First live call with Siemens WiMAX solution

(Business News & Technology News, 13 Jul 2005)

Siemens Communications recently succeeded in completing a live data transfer with SkyMAX, its WiMAX solution based on the IEEE 802.16-2004 standard, in its test lab in 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. Siemens will soon offer standard-compliant WiMAX radio networks, including end devices, to fixed and mobile network operators.

“This test demonstrates that we have met our target of being ready for the commercial deployment of WiMAX in the second half of 2005,” said Christoph Caselitz, President of Mobile Networks at Siemens Communications. “We will make SkyMAX available to our customer for trials.”

The SkyMAX solution includes a base station that uses orthogonal frequency division multiplexing (OFDM ) technology and modems as end devices. OFDM technology protects wireless broadband transmissions against most interference from echoes and multipathing. The SkyMAX modems use Intel’s PRO/Wireless 5116 chip, the first on-chip system for WiMAX that is based on the IEEE 802.16-2004 standard.

"We are all the more pleased about the first live data transmission from Siemens since it uses the PRO/Wireless 5116 Chip that we officially presented in April of this year", says Christian Morales, Vice President of the Sales and Marketing Group and General Manager of Intel EMEA. "This brings us a huge step closer to the joint vision of wireless broadband networks and services. Users will find these new communication options as indispensable as they do DSL or wireless LAN today."

The connection between the SkyMAX base stations and a number of modems was tested in a non-line-of-sight setup. The results demonstrated that SkyMAX is able to deliver services such as Web browsing, video streaming, VoIP and file transfers with a guaranteed level of quality.
