Agere demos 162-Mbit/s wireless LAN
The research is being done by a group of chip and systems companies at the Eindhoven University of Technology in the Netherlands. "We have shown the proof of concept and are working towards delivering silicon chips and systems. A lot more work needs to be done before a commercial system is available," Roman Polz, marketing director for Agere Systems' Client Systems Group in EMEA, told CommsDesign.com.
Polz said the group hopes to have a silicon solution ready by 2004. He would not name the project's partners, but said they included other chip makers as well as companies with systems expertise.
"We are committed to delivering technological advances that will support data-intensive applications and drive widespread growth in the wireless LAN industry. This demonstration offers a glimpse of the advances Agere is pursuing to fuel the expansion of wireless data beyond e-mail for business users into home applications such as multimedia entertainment," Polz said.
Polz said the group believes the technology will be able to compete effectively with wired communications links operating at over 100 Mbits/s, such as Fast Ethernet. Other groups are looking at similar approaches to very fast wireless networking using the 5-GHz range, and Polz added that the IEEE has already started looking at getting such technology standardized within the 802.11 umbrella.
The demonstration combines multiple input multiple output (MIMO) and orthogonal frequency division multiplexing (OFDM). Together, the two technologies are able to produce a robust wireless data link that can transmit data at more than 162 Mbits/s, depending on the total number of antennas deployed. OFDM technology divides the frequency band into numerous parallel sub-channels to guard against interference, while MIMO transmission significantly increases data rates with several antennas transmitting data streams at 54 Mbits/s and operating in the same frequency.
Data is transmitted with three separate transmitter and receiver antennas. The demonstration shows that the growth in data throughput increases proportionally to the number of antennas.
