CSR Powers USI's Consumer Handheld WiFi/Bluetooth Combo Module

6/17/2003 - CSR (Cambridge Silicon Radio), the world's leading single-chip Bluetooth company announced that its Bluetooth technology, BlueCore, is being used in a new combination WiFi and Bluetooth module from Taiwanese manufacturer Universal Scientific Industrial Co Ltd (USI). The module, which benefits from the low power consumption and small footprint of CSR's BlueCore, is targeted at consumer handheld applications such as PDAs, Smartphones, digital cameras, camcorders and printers. The USI combo module measures a compact 22x29 millimetres and is intended for embedding directly into the handheld device.

Given the proximity of the Bluetooth and 802.11b radios, the module employs CSR's channel skipping technology, minimizing interference between the Bluetooth and 802.11b radios and improving the throughput of the Bluetooth radio by as much as 50 percent over solutions that rely on MAC level signalling. Combining both wireless technologies into one card allows a notebook PC, for example, to connect to a wireless LAN using the faster 802.11b technology, and at the same time, to lower power Bluetooth peripherals (e.g. printers, mice and keyboards) or mobile handsets or to synchronize PDAs.

USI is incorporating Agere Systems' WaveLAN(tm) 802.11b wireless networking chip set in the combination Bluetooth/Wi-Fi module.

"Wireless users want the freedom to move untethered without losing their connection," said C.Y. Wei, Corporate Senior V. P. and General Manager of USI's Communication Business Group. "Our module combines two key wireless technologies - 802.11b and Bluetooth - to enable even greater data sharing and connectivity options for mobile applications. Moreover, USI's design expertise and manufacturing capacity offer customers total solutions to differentiate their products by quick time-to-market, best performance and desirable quality."

Eric Janson, worldwide vice president, marketing, CSR commented, "Because CSR silicon includes the full feature set of the Bluetooth specification and delivers the best Bluetooth performance in terms of coexistence with WiFi radios, our BlueCore technology is the standard choice for such combination designs."
