May 5th 2004 FOR IMMEDIATE RELEASE Supergold combat the interference threat that could kill off 802.11g 
This
press release in PDF-Format (25 KB)Universal solution for all manufacturers of Wireless LAN manufacturers Supergold claim the threat posed by third party interference to WLAN 802.11g communication could, if left unaddressed, could render the standard an industry ‘white elephant’. The company points to work being undertaken by the IEEE 802.15.2 Task Group to combat the threat of interference from Bluetooth equipped devices, which are now widely understood to compromise performance. Whilst the Task Group’s work will facilitate co-existence between WLAN and WPAN (Wireless Personal Area Network) systems, Supergold point to serious shortfalls in the proposals that ignore multiple sources of different types of interference experienced by 802.11g operating in the 2.4MHz spectrum. The IEEE 802.15.2 Study Group has for example, defined two sets of mechanism to enable coexistence, both of which, Supergold claim to be inadequate. ‘Collaborative’ mechanisms require WLAN and WPAN (Wireless Personal Area Network, typically Bluetooth) systems to communicate and collaborate in order to optimize use of the shared frequency. Several techniques have been defined, all of which compromise the potential throughput of either system, fail to address the threat posed by multiple sources of interference and totally ignore the problems caused by microwave ovens, portable telephone handsets, etc. Non-collaborative mechanisms allow systems to independently assess the quality of channels within the wireless spectrum in order to employ those that offer least interference. As with collaborative mechanisms, these techniques will not effectively address the problem posed by multiple sources of interference which will lead to unacceptable degradation of WLAN performance. Supergold claims that its technology, SIRS (Supergold Interference Reduction Scheme), which is compatible IEEE 802.11 standards while working independently, affords manufacturers an opportunity to combat the threat of interference without ongoing reference to standards bodies. Importantly, Supergold is making its encoding technology available to WLAN manufacturers free of charge for R&D and validation in order to prove concept and highlight the weaknesses of alternative solutions. Proprietary ‘two chip’ solutions impact production cost and only deal with performance on a co-location basis, that is, where both the Bluetooth and WLAN system operating on the same hardware, such as a notebook computer. As with IEEE802.15.2 mechanisms, ‘two chip’ solutions fail to address the interference from multiple third party sources and interference generated by non WLAN/WPAN equipment. By operating in the RF receiver chain independently of the IEEE 802.11x standards, Supergold’s SIRS addresses the issues of multiple sources of interference from whatever source operating in the same spectrum. An important benefit of operating independently of the standard whilst maintaining compatibility is that SIRS allows manufacturers to deal with the interference threat as standards evolve. Most important, implemented in the RF receiver, SIRS need only be present at one end of a connection in order to offer performance enhancement. This is important for manufacturers that expect to operate in multi-vendor environments. Supergold plans mass adoption of its technology by making it available free of charge to manufacturers that seek to prove concept and is in negotiation with leading chip set and system designers. It predicts that SIRS equipped systems will reach the market in early 05 in time for mass market adoption of 802.11g equipped WLAN equipment. Editor’s notes Supergold Communication Limited is a campus start-up company, which has rapidly developed high International recognition across the wireless community through its standards activities. Supergold is a research and development company specialising in coded solutions for wireless communications. Supergold technology improves the performance of air interface products by uniquely combining increased resilience to outside interference with improved data throughput. Supergold’s strength is in its expertise and IPR, which is targeted at fabless semi-conductor design houses and integrated circuit manufacturers/providers seeking to enhance competitive edge through embedded technology.
