The New FCC Regulator`s Mobile Plan - Wireless 4G
(Page 3 of 3 )
4G is the much anticipated successor to 3G and 2G standards, making it the fourth generation of cellular wireless. A 4G system can upgrade already-existing communication networks and will provide a comprehensive and secure IP-based solution. Many have high hopes for this new technology, believing that it will take voice, data, and streamed multimedia to a new level, providing users with services on an anytime, anywhere basis at exceptionally higher data rates that previous generations.
4G is currently being developed to accommodate rate requirements. It will also work as a defense against new applications that will eat up a great deal of bandwidth, such as wireless broadband access, multimedia messaging services, video chat, mobile TV, HDTV content, digital video broadcasting, and voice and data, which actually don't use as much bandwidth as the others.
The following are considered to be the main objectives of new 4G standard:
A spectrally efficient system.
High network capacity: more simultaneous users per cell.
A nominal data rate while the client physically moves at high speeds relative to the station. A data rate of at least 100 Mbit/s between any two points in the world.
Smooth handoff across unrelated networks.
Seamless connectivity and global roaming across multiple networks.
High quality service for next generation multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc).
Interoperability with existing wireless standards.
An all-IP, packet-switched network.
By all accounts, the new 4G system should share and utilize network resources to adequately meet the minimal requirements of all 4G-enabled users. Not so surprisingly, the new FCC regulator has been the biggest proponent of 4G technology and has made it his goal to "unleash the spectrum" for 4G mobile broadband because, according to Genachowski, the next generation of mobile technology will drastically change the face of communication.
During his speech at the CTIA conference, Genachowski devoted a great deal of time to discussing the 4G system and the role it would play in his Mobile Broadband Agenda. "More and more I hear people say that broadband is the future of mobile and I agree. I also believe the reverse is true - mobile is essential to the future of broadband and the next generation of mobile technology (4G) will make all the difference," Genachowski said. "4G will provide mobile connectivity several times faster than we have today. It will provide a mobile Internet experience comparable to today's wireline networks -- data rates measured in megabits per second instead of kilobits, latencies in mere milliseconds."
Many mobile providers are already on board. According to recent reports, Clearwire has already launched WiMAX in 14 markets, while Verizon, T-Mobile, and MetroPCS have each announced plans to launch LTE over the next couple of years. It appears as if AT&T is ahead of the game, as they've already launched LTE in specific cities across the country. Despite this progress, the process to convert to 4G will take time. "It's easier to roll-out a press release than roll-out a network," Genachowski said. "There is a lot of work to do and I know it won't be easy."
