Radios for next generation wireless networks

The next generation Internet will carry even higher speed data to offices and homes. A high data rate wireless network is needed to continue high speed data transmission to the ever increasing number of wireless computing devices, such as notebooks and PDAs, and to support high data rate applications that require video, etc. Next generation wireless networks will require multi-carrier modulation schemes such as orthogonal frequency division multiplexing (OFDM) with high levels of modulation such as M-quadrature amplitude modulation (MQAM) signal constellation to support high data rates and throughput over harsh wireless channels in the 2.4 GHz and 5 GHz bands. The future network will also have to support existing wireless LAN systems/standards such as 802.11a/b/g. The radios in such systems will have to provide high performance and be highly linear.
