What is 4G?

4G is not a company, a service, or a device. Like 3G, which ushered in voice and data technologies such as EVDO and HSPA, 4G ("4th generation") technology is the next evolution in wireless communication. It is a broad term used to describe all of the advances in wireless technology that will eventually replace 3G technology.

One of the strongest objectives for 4G technology is to create a network capable of providing fast speeds both indoors and outdoors with premium quality, making tasks like video conferencing, VOIP, and music and video downloading much smoother than what is currently available. High security will also be a priority as developers work to create new 4G systems.

While a full-scale deployment of 4G is still a ways off - likely in the 2010-2015 range - there are emerging new technologies already being tested and, in some cases, deployed. WiMAX, or Worldwide Interoperability for Microwave Access, is already available in many locations around the world and debuted in the US in September of 2008. WiMAX is available in several regions of the US from Clearwire under the brand name CLEAR (Sprint's XOHM product is being re-branded to merge with CLEAR) and is also re-sold by Sprint ("Sprint 4G") and others like Time Warner Cable and Comcast in select markets. Long Term Evoution, or LTE, is a second 4G technology, which carriers including Verizon Wireless and AT&T are developing to employ as the eventual broadband successor to UMTS. Verizon plans to launch their first LTE markets in the US in 2010. T-Mobile has also upgraded some of their network to HSPA+, which they are marketing as "4G".

As more 4G technology and services become available, 4Ginfo.com will continue to be a top source for all the latest news, developments, and products. We will be launching 4Gstore.com for the sale of products and services as soon as they become available.
