Commsonic has added a multimode multirate QAM modem and IEEE802.16 channel codec to its family of broadband communications IP.

Commsonic has added a multimode multirate QAM modem and 802.16 channel codec to its family of broadband communications IP The CMS0004 modulator and CMS0006 demodulator support QAM orders from 2 to 256 and are intended for a wide range of applications including terrestrial, cable and satellite links carrying up to STM-1 capacity (155Mbit/s)

The CMS0005 channel codec implements all of the physical-layer formatting, deformatting and FEC functions specified by the IEEE802.16a wireless metropolitan area network (WMAN) standard.

This new OFDM-based standard supports datarates up to approximately 100Mbit/s and has been designed for the robust delivery of multimedia services over fixed point-to-point and point-to-multipoint wireless links in the frequency range from 2 to 11GHz.

Its most immediate application is as a non-line-of-sight (NLOS) backhaul technology for 'hotspots' operating the 802.11 wireless LAN standard.

Commsonic's IP family is supplied with a source-level (VHDL) licence and includes vector-matched C++ models for use in system simulations.

Other family members include configurable Reed-Solomon and convolutional FEC codecs.
