Amended from PhysOrg:
 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.
Siemens will be one of the world's first companies to offer
standard-compliant WiMAX radio networks, including end devices, to
fixed and mobile network operators.
“This successful test demonstrates that we have met our ambitious
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 now 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 even when the radio link between sender and receiver
includes obstacles like trees or buildings.
