IMEC's Smart Multiple Antenna Technology Enhances Capacity of Wireless Systems October 7, 2003 (HONG KONG) -- IMEC, Europe's micro- and nanoelectronics research center, announced a solution for a smart and flexible multiple antenna system that enables optimal use of resources in wireless networks. Besides various MIMO (multiple input multiple output) operation modes, it also provides SDMA (spatial division multiple access), a feature that by upgrading the access point with multiple antennas, increases the capacity. Trade offs can be made between reach, capacitance and power consumption. The solution will be proposed under IEEE802.11n and other upcoming standards and will lead to low-cost, low-power broadband wireless solutions. The solution also offers a next-generation wireless systems roadmap, taking into account backwards compatibility with existing standards and systems. Next-generation WLAN services target specifications of up to 100Mbps at ranges up to 100m. This requires an increase in bandwidth efficiency of up to 5 times that can be achieved through multiple antenna modems and suitable space-time processing. IMEC's multiple antenna technology targets the implementation of two different system concepts whereby multiple streams can be transmitted in parallel: transmitter (TX) processing and receiver (RX) processing. The distinctive characteristic of this technology is that it allows the use of conventional terminal transceivers without spatial processing requirements, keeping most of the complexity within the base station. This can be achieved by combining both schemes into a single entity where all the spatial processing - whether transmit or receive - is done at the basestation: transmit processing in the downlink and receive processing in the uplink. The technology effectively combines the increased data rate offered by MIMO with increased network capacity offered by SDMA. The Matlab models of IMEC's multiple antenna technology are available to give industry early insight into these solutions. (NE Asia Online Editorial Dept) neasia.nikkeibp.com
