What Is 4G Wireless Internet?
The term 4G wireless Internet refers to the use of the fourth generation of wireless communication standards to provide Internet access on a scale that is equivalent to cellular phone coverage. This technology is used by a variety of service providers across the U.S. and allows for mobile broadband data transfer rates that may rival or exceed common home Internet speeds.

Background
-
The fourth generation of wireless communication standards, known as 4G, was developed by the International Telecommunication Union. These standards provide uniformity and compatibility for consumers and service providers that use 4G technology. The goal of 4G is to provide interoperable mobile speeds of up to 100 Mbps. This technology is the successor to the widely used 3G mobile networks, and 2G and 1G before it.
Wireless

Wireless Internet is the ability of a computer or other electronic device that has a modem to connect to the Internet without any physical cable connecting it. This is typically achieved through Wi-Fi access points in public places or private routers that may be located in businesses or homes. While the method of connecting is the same, towers often used by cellular phone companies distribute 4G wireless Internet. This technology allows for high-speed Internet access over a large area. Many electronic devices support 4G wireless Internet, including computers, tablets, cell phones and routers.

Speeds
-
Third generation, or 3G wireless technology provides average download speeds of 600 Kbps to 1.4 Mbps. With 4G, average speeds have increased to 3 to 6 Mbps. Actual speeds vary according to the service provider and location of use. These speeds are more in line with home Internet options such as cable and DSL. As the networks expand and the the technology used is continually advanced, speeds should increase and come much closer to the 4G standards set forth by the ITU.
Additional Information
-
As of May 2011, the coverage area for 4G networks is still expanding across the U.S. as the various providers steadily put additional infrastructure in place. Most major metropolitan areas are currently supported. Cell phone companies such as Verizon, Sprint, T-Mobile and AT&T, as well as many cable companies such as Time Warner and Cox support 4G wireless Internet. Much like its predecessors, 4G wireless Internet will require a subscription cost from any major company. Free Wi-Fi hotspots will continue to exist for the technology in many public locations.
