A few weeks before,
we featured the news release WiFi and Bluetooth chosen for phone from
Cambridge Silicon Radio: "CSR's intelligent RF design ensures trouble-free WiFi, Bluetooth and GSM/GPRS co-existence".
In September 2007, we covered the news from Cambridge Silicon Radio
concerning its BlueCore6
- take a look at IC upgrades Bluetooth possibilities
which says: "BlueCore6 includes CSR's AuriStream technology, which provides toll quality voice calls and is capable of a 40% reduction in power consumption".
Take a look also at the news release from Cambridge Silicon Radio, Revenues illustrate continued Bluetooth domination,
as well as Boards speed Bluetooth hands-free development from Ezurio,
and Single chip FM radio transceiver on display from Silicon Laboratories.
