CSR (Cambridge Silicon Radio), Intersil and SMART Modular Technologies have collaborated to produce a mini-PCI card combining Bluetooth and 802.11b wireless protocols.
The combo card uses CSR's channel skipping technology, minimising interference between the Bluetooth and 802.11 radios and improving the throughput of the Bluetooth radio by as much as 50% over solutions that rely on MAC level signalling. SMART expects to make samples of the card available in January 2003.
Intersil's 802.11b chipset PRISM 3 chipset is combined with CSR's BlueCore2 chip to produce a reference design with a mini-PCI standard form factor, that will enable it to be integrated into notebooks, PDAs and other battery-based portable devices.
The PCI solution provides Class 2 Bluetooth and has been developed to achieve Bluetooth radio receive sensitivity better than -82dBm and power output +2dBm (typical). The 802.11b radio receive sensitivity is better than -85dBm and power output +16dBm (typical).
