IRVINE, Calif.--Intersil Corp. today gave a loud endorsement to an industry task group, which voted on Thursday to move ahead with plans to set standards for higher-speed wireless networks with data rates up to 54 megabits per second in the 2.4-GHz spectrum.
The company said the stage was now set for the adoption of a new IEEE 802.11g standard, which will extend data speeds in the 2.4-GHz band from 11 Mbits per second in the current 802.11b "Wi-Fi" format. Intersil predicted that the vote by Task Group G of the IEEE 802.1 Committee will ensure backwards compatibility between future 54-Mbit/sec. wireless networks and today's Wi-Fi systems.
Intersil said the proposed 802.11g standard now includes backwards compatibility with mandatory modulation schemes that work with both the 802.11b Complementary Code Keying (CCK) and the 5-GHz band 802.11a Orthogonal Frequency Division Multiplexing (OFDM) format. Two optional modulations schemes--CCK-OFDM and CCK-PBCC--are also allowed if systems manufacturers choose to add them, according to Intersil, which sells chips for existing standards in wireless local area networks (WLANs).
The IEEE task group vote is "a huge win for the wireless industry for several reasons," according Gregory Williams, president and CEO of Intersil. "First, it is backwards compatible with the large installed user base of over 11 million Wi-Fi products. Second, it meets our customers' demands for significant speed increases in the 2.4-GHz band, necessary for multi-channel DVD-quality video and CD-quality audio applications."
Intersil said it is now developing a new chip set for the 802.11g segment and plans to introduce the product by the second quarter of 2002. The Irvine company said the new chip set will implement the current proposal's mandatory CCK and OFDM modulation schemes, supporting data rates up to 54 Mbit/sec.
