Spirea AB, a leading developer of integrated wireless solutions for the local area network (LAN) and personal area network (PAN) markets, today unveiled TripleTraC, the world's first dual band 5GHz/2.4GHz wireless LAN chip that features 802.11a, 802.11b and the European HiperLAN2 standard on a single chip. TripleTraC is designed for equipment manufacturers (OEMs) that are looking for low cost, highly flexible radio chips to enable consumer wireless devices to operate in wireless networking environments. The chip will begin sampling in Q2, 2002 and the company expects to be in full production by Q4 of 2002.
"TripleTraC enables our customers to smoothly and inexpensively migrate their products to next generation wireless networks," said Anders Oldeback, Spirea's vice president of sales and marketing. "Our achievement of the lowest cost, smallest form factor and highest power efficient radio flexible chip means that OEM's can enable wireless networking using almost any of today's standards and those emerging tomorrow."
The tri-mode, dual band CMOS radio comes at a time when the industry is debating when the demand for higher data rates of 54 Mbps offered by the 5GHz standard will outweigh the data rates of more common standards. TripleTraC will enable legacy applications to operate wirelessly and to smoothly migrate to higher data rates for broadband multimedia and digital video applications in enterprises and small and home offices (SOHO).
TripleTraC is a true single chip solution. The chip is based on a CMOS reconfigurable radio transceiver architecture. Moreover, the mixed-signal baseband is digitally programmable to accommodate different bandwidths for data rates reaching 22 Mbps in the 802.11b mode and 108 Mbps in the 802.11a mode. No external power amplifier, VCOs or channel filtering is needed.
"We recognized the RF characteristics of CMOS and realized that innovative design solutions at all levels; system, circuit and physical layout were needed to provide a robust, cost effective total solution," said Johnny Johansson, Spirea president and chief operating officer. "Our deep expertise in RF CMOS led us to combine the best in mature deep sub-micron CMOS technologies to deliver the first chip of its kind."
