Over Half of Cellular Backhaul Capacity will be Ethernet by the End of 2011
While microwave will remain the most common last mile link medium, Ethernet is playing an increasing role in supporting backhaul needs for cellular and WiMAX networks. Over half of cellular backhaul capacity will use Ethernet by the end of 2011, reports In-Stat. The transition to Ethernet will vary by region, depending on where mobile operators are in their transition to 3G and LTE networks. more

It's Make Or Break For WiMAX, Says Analysys
This year will be decisive in the development of WiMAX, which experienced major setbacks in 2007, says Analysys. "WiMAX suffered a major setback when the partnership between US operator Sprint Nextel, one of the technology's strongest advocates, and Clearwire fell apart in November," says Andrew Parkin-White, Principal Analyst at Analysys, and co-author of Mobile Market Perspectives 2008 (A summary of recent research into the evolving mobile market). more

High-Reliability Gallium Nitride HEMT for Use in Base Stations
Fujitsu Laboratories has announced the development of a new high-reliability technology for high power gallium nitride (GaN) high electron-mobility transistors (HEMT), as used in mobile phone base stations (amongst other uses). The new technology enables the transistors to operate even at the high temperature of 200 degrees Celsius for more than one million hours, equivalent to over 100 years, under pinch-off condition with a drain voltage of 50 volts(50V), thereby enabling the world's longest lifecycle for GaN HEMTs. more

STMicroelectronics Offers Turnkey Solution for Mobile WiMAX Base Stations
Shortly after the IEEE ratified the new 'mobile WiMAX' standard (802.16e), STMicroelectronics has announced its turnkey solution for 802.16e base-station modems. WiMAX/IEEE 802.16 (Worldwide Interoperability for microwave Access) is a global standard-based technology for broadband wireless access. Ratified last month, the new 'mobile' 802.16e standard ushers in a seamless, nomadic phase of WiMAX, where base stations can communicate with moving devices, allowing users to move around and maintain their broadband connection. more

Motorola and Intel Jointly Promote WiMAX
Motorola and Intel have announced plans to collaboratively foster greater industry momentum for WiMAX and to advance the use of mobile WiMAX technology, based on the proposed IEEE 802.16e standard, for both fixed and wireless broadband applications. Intel and Motorola plan to collaborate on specification efforts within the WiMAX Forum in an effort to ensure that network and device interoperability issues are addressed adequately. more

Siemens Communications recently succeeded in completing the first live data transfer with SkyMAX, a new end-to-end WiMAX ( Worldwide Interoperability for microwave Access) solution based on the IEEE 802.16-2004 standard, in its test lab in Milan, Italy. During the live link between a modem and a base station in the 3.5 GHz frequency spectrum, data was transmitted at a top speed of up to 12 megabits per second in 3.5 MHz bandwidth. Transmission rates as high as this had only previously been achieved with early proprietary systems. more
