IEEE 802.16n: 10GigE?

Posted by Sam Churchill on

A Project Authorization (PAR) for IEEE 802.16n is said to be working its way through informal committees. Anticipated to deliver 10 Gbps (fixed) and 1 Gbps (mobile) within 3-5 years, WiMAX 3.0 is anticipated to be ten times the speed of today’s fastest networks, using 4×8 MIMO and channel ganging.

Using ten, 6 MHz “white space” channels, WiMAX 3.0 is expected to finally kill off broadcast television, enabling mobile cable television stations in a backpack.

It was only this week that the IEEE approved the 802.16m standard. The IEEE 802.16m standard, also known as WiMAX 2, will deliver 100Mbps to mobile users. The International Telecommunication Union (ITU) approved IEEE 802.16m as an IMT-Advanced technology back in October, 2010.

IEEE 802.16m enhancements include multi-user MIMO, multicarrier operation, and cooperative communications. It supports femto-cells, self-organizing networks, and relays. Major worldwide governmental and industrial organizations, are adopting the WiMAX 2.0 standard.

Samsung supports the WiMAX 2 standard, demonstrating a WiMAX 2 trial system at 330Mbps, at CEATEC in Japan, last year. Japan’s UQ Communications demonstrated wireless streaming of full-HD 3D videos over a WiMAX using the Samsung gear. The first 802.16m dongles should be available to consumers in late 2011, with more wide-spread commercial deployments starting in 2012 (pdf).

The WiMAX 2.0 standard is backward compatible with 802.16e, the current WiMAX standard.

Although WiMAX 2 may be ready to roll out next year, Sprint, which owns 54% of Clearwire, may be leaning towards LTE on the Clear 2.5-2.6 GHz spectrum. Currently Clear uses three different 10 MHz channels per sector. WiMAX2 would double the bandwidth to 20 MHz.

Instead of consuming a total of 60 MHz, however, WiMAX 2 enables spectrum reuse, where the same frequency is used on all sectors. Users avoid interference by using different sub-channels on the COFDMA carrier.

Dell’Oro predicts global LTE deployments will exceed $6 billion by 2014, with annual revenues of the overall annual infrastructure market revenues forecast to reach $43 billion over the next 5 years.

The five biggest telecom equipment manufacturers in the world, Alcatel Lucent, Ericsson, Nokia Siemens Networks, Huawei and ZTE aim to get a piece of that action, but they’re all going with LTE and the next iteration – LTE Advanced – which offers speeds similar to WiMAX 2.0.

Clearwire’s CTO John Saw tell’s Light Reading’s Dan Jones about their LTE and WiMax 2 trial in Phoenix.

John Saw says they’ll test 802.16m in Phoenix when production gear is available. That may be soon.

ABI Research says more than two billion of the world’s population is now being covered by high-speed data networks, with more than 500 3G networks, and over 300 WiMAX and LTE announcements to date. World-wide, mobile devices with integrated wireless broadband are expected to top 2 billion by 2014, according to research firm In-Stat.
