What Is The Difference Between 4G Internet And 3G Internet

You may hear about 4G and 3G over and over when you’re looking for a phone, yet you may have no idea what this means. When selecting a smartphone, you must also select a data network. Your choices are 3G and 4G Internet. In this article we will compare and contrast the two.

The first thing you need to know is that G is the first letter in “generation”. Each new generation of mobile phone means obsolescence for the existing generation. For example, 1G and 2G phones are the digital phones of the past.

In 2003, 3G phones were introduced in the United States. This brought along high speed Internet and mobile broadband. Today, there are many different incarnations of 3G, and you can get very high speeds, indeed. Now we have 4G technology. It is supposed to be faster, deliver better reception and voice quality and allow more data and network capacity.

Even though the International Telecommunications Union (ITU) made attempts to set 4G standard requirements, carriers simply ignored them, so there are really no standards. As with 3G, there are multiple incarnations of 4G, and performance may not be any better than 3G in some instances.

The best way to select the fastest 4G speed is to look at the results of popular and reliable testing. Recent tests found that the fastest 4G Internet speeds were delivered by:

* AT&t 4G LTE
* T-Mobile LTE
* Verizon LTE
* T-Mobile HSPA+
* Sprint LTE
* AT&T HSPA
* Verizon 3G
* Sprint 3G

You may be wondering what LTE stands for. This stands for Long Term Evolution. This is one of the many technical processes applicable to 4G Internet delivery. As matters now stand, we expect that Sprint will rise higher on the list as it develops its Sprint LTE Spark network.

Why should you change from 3G to 4G Internet?

More and more people everyday are switching to 4G phones, so simply being able to communicate  with others is a big reason. Of the big smartphone providers, Verizon provides 4G LTE coverage across the nation. Other nationwide services include MetroPCS and T-Mobile. AT&T’s LTE coverage is broad and continues to expand. Sprint will soon overtake them all.

What should you be careful of? Watch out for off brands that sell old technology. Lesser smartphone brands may try to pass off 3G or very early 4G cheaply; however, this technology will soon be obsolete. When purchasing a new smartphone, always go for the latest technology so that you won’t have to replace your phone before you even get much use out of it.

Why is 4G Internet so much better? When you are streaming video, surfing the Internet or transferring data you will definitely notice the big improvement in speed and quality with 4G. Be sure to get a service plan that can handle the amount of data use you need. When using 4G, it is easy to let this get away from you fast.

People who have switched from 3G to 4G are generally much happier with the speed of data transfer, but they don’t report a lot of improvement in problems with dropped calls. This has more to do with the carriers, some of which are still using older networks.

The bottom line is, if you want to be prepared for the future, a 4G phone is a must-have. Get the best technology you can afford and consider it an investment and a hedge against the need for multiple upgrades and replacements in future.

Convergence 4G Phones

Samsung and YTL Comms are leading companies to reveal a world first in convergence 4G phones. This phone is known as the “Yes Buzz” which is an “all-in-one” mobile and 4G “high speed broadband” phone. These 4G phones feature a keyboard and a key pad that slips out of the device.

The Yes Buzz synchronizes contact details and each Yes account will be offered with a “mobile”“phone number and broadband “Internet access. This will result in smoother convergence in data and voice. Customers can now enjoy higher speeds offered in the broadband and ways to enjoy voice solutions, SMS and mobile chat. Customers will be advised on buying credit in order to operate their services.

“Yes Buzz” 4G phones are structured mainly around what is known as a usage plan, whereby users are able to spend in accordance to the amount of data they use. The community for Yes 4G offers discounts up to 30% to their specialist customers who purchase and use data on a larger scale.

“Yes” has confirmed that the coverage is possible due to base stations (thousands) which are already providing up to 65% of coverage. This a big comparison to the P1 4G who only have up to eight hundred types of base stations available.

“Yes” has been regarded as the fastest 4G internet services provided by mobile. There are four gadgets on offer for these phones:

Yes Go

This is a portable broadband USB dongle and the connection rate is up to five times faster, compared to the usual 3G modem. The USB modem offers 270 level turning, hinged characteristics.

Yes Buzz is an application produced by the company known as Samsung offers more features than the basic cell phone. The 4G phones offer support types of messaging such as SMS, push mail, and IM.

The phone known as Yes Buzz does not require the use of a SIM card in order to operate and can act like a type of USB modem all at once.
The Yes Buzz phones are a leader for 4G Services and new types of generation phones. The joint venture between the two companies YTL and Samsung offer the very first type of 4G mobile phones to the world.These 4G options will create faster Inernet connections at afordable prices.

Benefits of Mobile 4g Solutions for 4g Phones and 4g internet

A lot of consumers have started to hear about these terms in recent years such as ‘mobile 4g’, but do not know what they are really about. This is fine as many consumers do not understand the intricacies of the networks surrounding them, but it is important to try and understand them. By understanding these networks, it becomes easier to recognizes the best mobile solutions out on the market. Let’s take a glance at what mobile 4g is all about and the benefits surrounding it.

Speed

Mobile 4g solutions are incredible because they offer speed that was never possible in the past. Most individuals have become used to using Wifi solutions that are simply not up to par.

The speed on Wifi solutions that can be seen at every corner just do not have that modern age ‘oomph’ that consumers require. This is why 4g networks have become an intrinsic requirement for those who want to be speed demons with their mobile devices.

The networks like in Telus Fort Saskatchewan are designed to offer unmatched speeds and this is on a short and long-term basis. One does not have to fret over reduction in speeds as they move from one place to another. It is more consistent than anything else out there and that is a major plus point.

Increasing Coverage

What about the coverage for one’s mobile? There is no point in having the world’s finest network, if there is no coverage to be found. This is why 4g networks are raved about because they are able to provide an all-encompassing coverage that is much better than anything else out there.

Coverage is essential in contemporary times and one cannot afford to go without their mobile devices for a long period of time. This is why it becomes imperative to find an option that will last long and provide consistent results.

Security

As mobile devices become such an invaluable and key part of everyone’s lives, it becomes imperative to have a quality security solution.

General networks just do not have the type of security features that are worth one’s time and money. Most individuals do a lot of things when it comes to their mobile devices such as banking, buying, and selling. In these cases, it becomes important to make sure the network has the right kind of security in place.

These 4g networks are imperative because of these security features that are of the highest quality.

Affordable

In the end, everyone wants the best overall package but at a price that is affordable for their budget. There is no point in looking at a great solution, if it takes a huge chunk out of one’s budget.

4g networks are great because they are wonderful when it comes to price ranges. Everyone can afford them without having to sell their house or car.

This is the way of the future and the networks continue to be upgraded, which increases their benefits as time passes by. This is as good as it gets for those who want the best.

Wired Explains: Everything You Need to Know About 4G Wireless

This article I came across at Wired.com written by Priya Ganapati really ties everything together in order that you completely 4G Wireless Technology enjoy!

If your smartphone seems more like a slowphone, hang in there. The next generation of wireless technologies, known as 4G, promises blazing-fast data transmission speeds.

The first 4G handset, Sprint’s HTC Evo, hits U.S. retail stores Friday, making this a good time to answer your questions about the fast wireless technology behind the Evo.

4G is just getting started, and even Sprint’s network is only available in a handful of cities. But in just about two years, 4G could be almost everywhere.  All major U.S. wireless carriers are working on upgrading their systems to 4G — though we would prefer if some, like AT&T, got their 3G networks working properly in the meantime.

So what goodness will 4G bring to the world and should you hold your breath for it? Read on for our quick guide to all those burning questions about 4G.

Got more questions? Ask them in the comments, and we’ll update this post with answers.

What is 4G?

4G is a loose term for the fourth generation of cellular communications, offering speeds that are about 10 times faster than they are on current third-generation, or 3G, networks.

Its higher data speeds could make smartphones much more comparable to PCs, giving them better multimedia and gaming capabilities.

What are the different 4G technologies?

Just as in the 3G world, 4G technologies fork into two broad camps: LTE and WiMax.

They’re not aligned with the old GSM vs CDMA split, though. This time, AT&T and Verizon are moving towards LTE, while Sprint has thrown its weight behind WiMax.

There’s quite a bit of debate on whether LTE and WiMax meet all the technical requirements to be classified 4G technologies. The International Telecommunications Union suggests that WiMax, the standard that Sprint calls 4G, is actually part of the 3G family, though Sprint markets WiMax as 4G and its speeds are comparable to current LTE speeds.

WiMax has its roots in the wireless broadband access industry and is supported by IEEE, while the LTE standard has been created by a consortium of mobile companies. WiMax requires a new network to be built whereas LTE is an evolution of existing CDMA/HSPA networks.

How fast will 4G be?

The maximum theoretical data transfer with 3G technology is 2 Mbps.  But in practice, you won’t get more than 500 Kbps to 1.5 Mbps, depending on your carrier, the location of the cell tower, congestion, etc.

4G ups the game.

WiMax can offer peak download data speeds of up to 6 Mbps and up to 1 Mbps for uploading data. WiMax rival LTE says it can do much better. It has peak download speeds of 100 Mbps and can support uploads at the rate of up to 50 Mbps.

But remember, these are theoretical speeds conjured by lab rats. Add a million devices on the network, downloading Comedy Central clips on Flash-enabled phones, video chatting, streaming the next chapter in the Saw movie franchise and uploading parodies of the latest Lady Gaga release, and those speeds will drop.

For a better idea of what you can expect with your 4G device, take a look at what tests on the Sprint WiMax and Verizon LTE 4G networks have shown. PC World reports that the HTC EVO 4G phonenever broke the 3 Mbps mark in its tests of the phone nationwide. And Verizon’s tests showed in the real world, its download speeds ranged from 5 Mbps to 12 Mbps and with upload speeds of 2 Mbps to 5 Mbps.

I want 4G now. Where can I get it?

About 36 U.S. cities including Seattle, Baltimore, Chicago and Dallas already have 4G coverage from Sprint. There are still some big names like San Francisco and New York missing from the list, but Sprint says 4G will arrive there by the end of the year. You can check out the detailed list of the cities that have 4G coverage on Sprint’s site.

Do I need a new phone to take advantage of 4G?

Yes, you will need a new phone. The first 4G smartphone is the HTC Evo, a device running Google’s Android operating system, which launches today. HTC Evo is a gorgeous device with a 4.3-inch touchscreen, two cameras, GPS navigation, HDMI output and mobile hot-spot capability.  The phone costs $200 with a two-year contract. Sprint is also charging an extra $10 a month, in addition to its standard data plans, as a service fee to access the 4G network.

If you don’t have 4G connectivity where you live, you can still use the phone with existing 3G networks.

Meanwhile, Samsung is creating a 4G phone for MetroPCS. The excitingly named phone SCH-r900 will have a 624-MHz processor, 128 MB of RAM, a 3.2-inch display, and Windows Mobile 6.1 operating system.

There’s been an iPhone 3G, iPhone 3G S.  So is an iPhone 4G next?

Sure, Apple can add the 4G tag to its next iPhone if it wants to, and “iPhone 4G” is how the company has referred to its next-generation smartphone in legal documents. But we doubt that it will have 4G network connectivity — unless Apple’s creating a phone exclusive to Sprint.

What are the 4G plans of the major U.S. carriers?

AT&T: The carrier plans to start trials of its 4G network later this year. AT&T will make the most of its LTE deployments in 2011. But even that may not be enough to free us from the tyranny of capped data consumption and gaping holes in its coverage.

Verizon: In 2009, Verizon tested its 4G wireless service in Boston and Seattle. Verizon said it plans to start offering the service commercially this year in about 30 cities so it can cover about 100 million users. By 2013, Verizon hopes to have the 4G service available nationwide.

Sprint: Sprint is leading the 4G charge with the network already available in at least 36 cities. By the end of the year, most major cities will be covered by Sprint’s 4G network.

T-Mobile: T-Mobile is in no hurry to get to 4G. Maybe because it first needs to get its 3G network in order. The wireless carrier is still talking about upgrading its 3G network to 3.5 G or HSPA+. HSPA+ will come to Los Angeles and other major cities in the United States this year, says T-Mobile. 4G is clearly a long way away.

MetroPCS: The first LTE 4G phone could come from MetroPCS, which is working with Samsung on the device. MetroPCS plans to start its 4G service later this year in cities such as Las Vegas.

Give me some background: What’s the history here and how did we get to 4G?

Cellular systems have evolved in four major phases or generations. The first generation, or 1G, technology was analog and transmitted voice calls only.

The second generation, or 2G, introduced digital transmissions and offered the first support for data, although the focus was still on voice calling. Second-generation phones are based on one of two standards: GSM (used by T-Mobile, AT&T, and most overseas carriers) and CDMA (used by Verizon and Sprint). In either case, average data speed on a 2G network is around 9.6 Kbps, about the same as a ’90s-era modems.

The intermediate “2.5G” level is where things get a little fuzzy. In the GSM camp, a standard called GPRS, which offered better data transmission capabilities, came to be known as 2.5G. GPRS has evolved into the EDGE networks (up to 400-kbps data speeds) still used by many phones today. As for the CDMA universe, 2.5G is referred to as 1XRTT, or just 1X. In the real world, it is known as EVDO and promises download speeds ranging from 600 kbps to 1.4 Mbps.

There’s been some debate on what constitutes 3G. Broadly speaking, 3G is defined not by the underlying technology, but by its speed: up to 2 Mbps. Verizon and Sprint’s 3G systems are referred to as EVDO, while AT&T and T-Mobile use HSDPA. A further level, known as HSDPA+ or Turbo 3G, can support download speeds of up to 14 Mbps.

The next step is 4G.

I want all the details, the nitty-gritty behind the two 4G standards. How do they differ?

LTE or Long Term Evolution, is a standard evolved by a group called the 3rd Generation Partnership Project. It is an all-IP network based upon the same core protocol of the internet, TCP/IP.

Both LTE and WiMax use the principle of Orthogonal Frequency-Division Multiple Access, which conceptually has been around since the 1960s. OFDMA is based on the idea of frequency-division multiplexing, which is a method to transmit multiple data streams over a channel.  In case of OFDMA, a digital data stream that needs to be transmitted is split into multiple pieces, each of which is modulated onto a separate carrier. These sub-carriers are combined together at the end.

The difference between LTE and WiMax lies in how they handle the channel for processing data. WiMax processes all the information in a wide channel. In case of Clearwire’s implementation of WiMax, that means the about two-thirds of the channel is used for downloads, while a third is used to upload data.

LTE splits the channel into two parts using frequency-division multiplexing, so the download and upload speeds are better balanced.

Just say it. Is WiMax better or LTE?

Peanut butter or chocolate? Lost or The Wire? Havaianas or Birkenstocks?  There’s no easy answer. It depends on where you are and what you can get access to.

If you want 4G now, WiMax is pretty much your only choice. It’s also an open standard supported by IEEE. And it is less expensive for service providers to upgrade their equipment to than LTE.

But LTE is coming and almost all the major U.S. carriers, except Sprint, will be supporting it. So ultimately, LTE might win in the long run.

Thanks for this Priya!

Everything You Need To Know About 4G Wireless Technology

Came across this great article over at TechSpot.com that everyone should read.  It was written by Jose Vilches enjoy!

While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind. With 4G the promise is that you can get real mobile broadband to go. In this piece we are going to tell you all about the technology and its benefits, who offers it or plans to, how much it costs, and the gear you need to enjoy the next generation of wireless broadband today.

But first, some background: 4G is the short name for fourth-generation wireless, the stage of mobile communications that will enable things like IP-based voice, data, gaming services and high quality streamed multimedia on portable devices with cable modem-like transmission speeds. It’s a successor to 2G and 3G wireless, whereby the first signified the shift from analog to digital transmissions, bringing data services like SMS and email to mobile phones for the first time, and the second refers to the advent of things like global roaming as well as higher data rates.

Think of wireless generations as a handful of services that get faster and more feature-rich as newer technology becomes available. The 3G networks that we use today allow us to stream video, download music and files, and surf the web at average download speeds from 600Kb/s to 1.4Mb/s. With 4G you’ll be able to do the same but at much faster rates, while the extra bandwidth opens the door for newer applications.

There are a number of standards and technologies pertaining to each wireless generation — GSM, cdmaOne, GPRS, EDGE, CDMA2000, UMTS (also marketed as 3GSM), HSDPA, among others. For practical reasons, we won’t be dwelling on the technicalities of each term and instead will move onto the ones that involve our topic of interest here: 4G.

Although no set of standards have been established as of yet by the International Telecommunication Union (ITU), the authority on such things, two competing technologies have been proposed: LTE and WiMAX. Many service providers often use the term 4G mobile broadband to describe the technologies they are offering based on their own, sometimes distorted definitions. However, current implementations are largely considered pre-4G, as they don’t fully comply with the planned requirements of 1Gbit/s for stationary reception and 100Mbit/s for mobile.

Besides speed, several other guidelines have been traced for wireless communication standards to qualify as 4G. In a nutshell, they should be very spectrally efficient, should dynamically share and utilize the network resources to support more simultaneous users per cell, have smooth handovers across heterogeneous networks, offer high quality of service for next generation multimedia support, and should be based on an all-IP packet switched network.

LTE

Short for Long-Term Evolution, LTE is considered by many to be the natural successor to current-generation 3G technologies, in part because it updates UMTS networks to provide significantly faster data rates for both uploading and downloading. The specification calls for downlink peak rates of at least 100Mb/s and an uplink of 50Mb/s, but going by real world tests its transfer speeds will more likely range from 5-12Mb/s for downloads and 2-5Mb/s for uploads.

LTE is being developed by a group of telecommunications associations known as the 3rd Generation Partnership Project, or 3GPP, as an eight release of what has been evolving since 1992 from the GSM family of standards.

There are two fundamental aspects of LTE. The first is that the technology finally leaves behind the circuit switched network of its GSM roots and moves to an all-IP flat networking architecture. This is a significant shift which in very simple terms means that LTE will treat everything it transmits, even voice, as data. The other big change relates to the use of MIMO technology, or multiple antennas at both the transmitter and receiver end to improve communication performance. This setup can either be used to increase the throughput data rates or to reduce interference.

Many big-name global operators and mobile communications companies are backing LTE in the race for 4G mobile broadband, including Vodafone, Orange, T-Mobile, LG Electronics, Ericsson, Nokia, Siemens, NTT DoMoCo, and others. In the U.S., Verizon Wireless has said it is going commercial with its LTE network in the fourth quarter, with 25 to 30 markets up and ready at launch. AT&T and T-Mobile claim they will begin to deploy LTE in 2011, but in the meantime both networks have moved to HSPA 7.2 and the latter plans to roll out HSPA+beginning this year. Theoretically these can support speeds of up to 7.2 and 21 Mbps, respectively, but in real world scenarios they are only marginally faster than most 3G data services.

The reason behind LTE’s strong industry support lies in the relative ease of upgrading from current 3G networks worldwide over to LTE mobile broadband, compared to the significant infrastructure build out that WiMAX has taken thus far. Fewer cell sites have to be built and penetration into buildings is better at the 700 MHz spectrum LTE uses. However, WiMAX deployments are already up and running while LTE’s formal debut is still a few months out.

WiMAX

WiMAX is a wireless broadband access standard developed and maintained by the IEEE under the 802.16 designation. As its name suggest, WiMAX can be thought of as an extension of Wi-Fi designed to enable pervasive, high-speed mobile Internet access on a wide range of devices, from laptops to smartphones. The current implementation is based on the 802.16e specification which offers theoretical downlink rates upwards of 70Mbps and up to 30-mile ranges.

Again, “theoretical” is the keyword here as WiMAX, like all wireless technologies, can either operate at higher bitrates or over longer distances but not both. Production networks being operated in the United States are seeing average speeds go from 3 to 6Mb/s, with bursts up to 10Mb/s. Like LTE — and Wi-Fi 802.11n for that matter — WiMAX supports MIMO technology, which means that additional antennas can increase the potential throughput.

There is no uniform global licensed spectrum for WiMAX, but three have been listed: 2.3 GHz, 2.5 GHz and 3.5 GHz. In the U.S., the biggest segment available is around 2.5 GHz and is already assigned primarily to Clearwire, a wireless internet service provider in which Sprint Nextel holds a majority stake.

In terms of total available 4G spectrum to deploy their services, Clearwire has several times more than its competitors, which have smaller portions of the 700 MHz band. However, Verizon and AT&T are not too worried about this as they can re-utilize spectrum being used right now for 2G and 3G services by upgrading these to LTE when the demand is there.

Furthermore, as mentioned earlier, the 700 MHz band that both Verizon and AT&T plan to use has enormously better range and penetration of buildings than the same power of signal at 2.5 GHz. Some experts have said that 700MHz will require as few as one-quarter as many base stations to offer identical coverage to 2.5 GHz.

As you might have guessed, the industry players behind these 4G technologies reflect the history of each standard. Whereas LTE biggest supporters are, in general, telecommunication service companies and handset manufacturers, WiMAX counts the likes of Intel, Cisco and Google among its most important backers. It should be noted though that many companies like Nokia or Motorola are members of both industry groups, with different levels of involvement.

The ‘Real’ 4G, Products and Availability

The ‘Real’ 4G Still a Long Ways Off?

Like we mentioned before, neither WiMAX nor LTE are truly considered a 4G technology by the International Telecommunications Union. As defined in their International Mobile Telecommunications Advanced (IMT Advanced) family of standards, these technologies must have target peak data rates of approximately 100 Mb/s on high mobility devices like cell phones and approximately 1 Gb/s for stationary devices like a 4G modem at home.

Just like the so-called 2.75G EDGE standard was developed to provide speeds several times faster than 2G data (GPRS) before 3G could be deployed, current implementations of WiMAX and LTE are largely considered a stopgap solution that will offer a considerable boost while WiMAX 2 (based on the 802.16m spec) and LTE Advanced are finalized. Both technologies aim to reach the objectives traced by the ITU, but are still far from being implemented.

In the United States, both T-Mobile and AT&T have moved to UMTS and various flavors of paired HSDPA / HSUPA, while on the CDMA front Sprint Nextel and Verizon Wireless support the EV-DO network. Download speeds vary from carrier to carrier depending on several factors, but on average they are somewhere between 600Kb/s and 1,400Kb/s.

In the case of Sprint, however, they’ve opted to go the WiMAX route because it was a near-term solution for which the company had enough spectrum to deploy right away. So while the ‘real’ 4G may still be a long ways off, we’ll take all the speed we can get at the moment. Today that’s 3-6Mb/s with Clearwire’s WiMAX service.

We expect operators to maintain their existing 2G or 3G networks for the foreseeable future, to support voice and narrower-band data while providing ubiquitous coverage. WiMAX and LTE will initially be deployed as an overlay network for fast data transfer rates, with multi-mode handsets (EV-DO / WiMAX or HSPA / LTE, for example) enabling users to get the best of both worlds as operators build out their 4G networks over several years.

Products and Availability

The biggest WiMAX provider in the U.S. is Clearwire, with their Clear service currently available in 30 markets including big cities like Atlanta, Las Vegas, Portland and most recently Houston. By the end of the year the company expects to expand its coverage to 80 major markets, reaching over a hundred million potential customers. Comcast, Sprint, and Time Warner Cable act as wholesale providers selling access to the same underlying WiMAX network as well.

Clear’s mobile and residential plans can be purchased by the day or by the month, with several no-contract options available. Home Internet service plans start at $30 per month for unlimited data, while mobile Internet plans start at $40 per month and a combination of the two is available from $55. True road warriors can also sign up for a dual-mode plan, offering the speed of Clearwire’s WiMAX network where available and 3G mobile Internet connectivity elsewhere.

 

Besides from choosing the plan that fits you, new gear is required to access this service. The easiest way to get up and running is with one of several USB dongles, which are available at low prices from Clear itself when signing up to a plan, or separately starting at $50 and all the way up to $225 for WiMAX and 3G coverage with the same device. There is also a range of stationary modems for home or office use, as well as Sprint’s Overdrive device, which serves as a portable hotspot for up to five Wi-Fi-enabled devices to hop on Clearwire’s WiMAX and 3G networks.

If you want support built inside your laptop, there are an increasing number of options out there with mobile WiMAX technology from Intel available out of the box or as an option. These range from netbooks to business-oriented laptops like the Lenovo ThinkPad Edge, which sells for around $900, and all the way up to luxury desktop replacements.

Sometime during this spring, Sprint is expected to release the first “4G” phone in the U.S. — and it’s a monster. Dubbed HTC EVO, this Android-based phone will sport a large 4.3-inch screen, 1Ghz Snapdragon processor, 512MB of RAM, an 8-megapixel flash-equipped camera capable of recording 720p video, a 1.3-megapixel front facing camera for placing video calls, and offer tethering of its speedy WiMAX signal to double as a portable hotspot. Of course, this will be a dual-mode smartphone, so outside of WiMAX areas the EVO will fall back to Sprint’s EV-DO Rev. A network.

On the other side of the fence, Verizon is expected to launch its LTE network in 25 to 30 markets before the end of the year. There’s not much we can tell in the way of pricing or product details yet, but we know the carrier doesn’t plan to launch its first LTE-based cell phone until mid-2011. Meanwhile, MetroPCS is also getting ready to roll out its LTE network in “various metropolitan U.S. markets” this year and is partnering with Samsung for the first compatible phone.

A Future of Convergence?

As you can guess, today’s debate lies on which technology has the most advantageous position. WiMAX is available now, but even Sprint and Clearwire’s highest ranking executives have admitted that LTE might eventually become the dominant 4G technology throughout the world. That’s not to say they are fighting an already lost battle. While they believe WiMAX has a lot of potential, and plan to continue pushing it, their decision to back this technology is all about timing. By the time LTE hits the market WiMAX will be available in at least twice as many cities.

On the other hand, GSM network standards dominate over 80% of the cellular markets worldwide, so it’s only natural that most mobile operators will want to move to LTE, as it’s rooted on the same technology they’ve worked with for over a decade — Verizon being the obvious exception with their network based on CDMA standards. Another important factor, as mentioned earlier, is that LTE requires significantly less infrastructure and thus will be cheaper to deploy.

Because both technologies are so similar there has been talk about them converging in the future. Clearwire CEO Bill Morrow emphasized this idea at the recent CTIA Wireless trade show, saying that the wireless industry should focus on the similarities between WiMAX and LTE rather than their differences. Motorola has added to this concept saying that they re-use much of its WiMAX technology when building LTE gear. Morrow envisions both technologies merging into one network standard, but even if that doesn’t pan out, he says they can add LTE to their network if necessary.

Verizon was quick to express doubt this will ever happen, but ultimately it’s up to the standards bodies and the driving forces behind them. Regardless if such convergence ever gains traction, for now WiMAX is at least a year ahead of LTE in terms of major commercial deployments and is moving full steam ahead. Clearwire will likely market WiMAX devices (and later on WiMAX 2) exclusively for the next 2-3 years, adding an LTE signal with minimal change to its antennas when — and if — the market demand is there as the LTE device ecosystem matures.

The leap to WiMAX in its current state is really more like going from dial-up to DSL. It’s a nice speed gain, comparable to some of the lower-end home broadband plans, but more of an intermediate step to something much faster. In the short term that could be LTE. We’ll have to reserve judgment until it’s available commercially, but the fact remains neither technology will make users want to drop their speedy cable modem service just yet.

If you are not looking to do extremely demanding broadband usage, and spend most of your time within Clear’s WiMAX coverage area, then the increased data speeds could be attractive for working at home or on the road without having to worry about finding a Wi-Fi hotspot. Sprint’s upcoming HTC EVO handset might also play an important role in getting new customer sign-ups, as the first and probably only smartphone capable of 3-6Mbps download speeds that can also double as a portable Wi-Fi access point for as many as eight devices.

As you can see Jose takes you from the current right to what looks to happen in the future.  I hope you enjoyed his article we sure did!

4G a.k.a. 4th generation wireless is the stage of mobile communications with data, gaming, IP based voice and high quality multimedia enabled on mobile devices. Its predecessors; 2G and 3G wireless are now outdated in most of the countries. 2G signifies the shift from analog to digital transmissions that brought email and SMS to mobile phones, while 3G went further by adding global roaming and higher data rates. 3G allow us to stream video, download music files and surf the web from 600Kb/s to 1.4Mb/s. 4G allow for the same with a much faster rate, and the extra bandwidth will open doors for newer applications.

There are various standards and technologies pertaining to each wireless generation. GPRS, GSM, CDMA2000, EDGE and HSDPA were all marketed 3GSM. 4G goes even further on improving these technologies and standards. The two competing technologies in 4G are LTE and WiMAX. The download speeds for 4G is planned as 1Gbit/s for fixed reception and 100Mbit/s for mobile.

Long Term Evolution or LTE is the natural successor to the current-generation 3G technologies. It updates UMTS networks to provide significantly faster data rates for uploading and downloading. LTE makes efficient use of the available spectrum with channel bandwidths from 1.25 to 20MHz. The transfer speeds will range from 2-5Mb/s for uploads and 5-12Mb/s for downloads. There are two important aspects of LTE. It leaves behind the circuit switched network of its GSM roots and moves to an all IP flat networking structure. The other aspect is the use of MIMO technology to improve communication performance. The reason for the popularity of LTE is the ease of upgrading from current 3G networks worldwide to LTE mobile broadband.

WiMAX is an extension to the Wi-Fi system in order to enable high speed mobile internet access on a wide range of applications. WiMAX offer a down-link rate of 70Mbps and up to a 30-mile range. WiMAX also supports MIMO technology, which means that additional antennas can increase the potential throughput.

The most significant benefit of 4G is the amazing speed. The increased bandwidth allows for much faster data transfer rates. It is highly beneficial for mobile devices. A superior, uninterrupted connection is guaranteed with 4G. Video chats and conferences are made easy with 4G.  Streaming music, videos and movies at a much faster speed is possible with 4G. Other benefits include: 4G has more coverage than Wi-Fi, and it covers up to 30 miles, complete connectivity is guaranteed at all times, 4G has more security, privacy and safety features and the pricing is affordable etc.
