Wifi, Bluetooth, and FM Radio On A Single Chip
Chip manufacturer Broadcom has just announced plans to begin manufacturing a new low-power chip featuring not 1, not 2, but 3 functional radio services on the same surface. Most chips in production now are relegated to a single wireless broadcast spectrum. As a result, any manufacturer that wants to integrate Bluetooth and Wifi on a single device has had to use multiple micro-chips, thus increasing power consumption and overall device size. Spectrum interference between Bluetooth and Wifi has stopped manufacturers thus far, but Broadcom seems to have developed a viable solution by using a single antenna for all 3 integrated services.

They can’t use a single antenna for all three – at a minimum you’ll have an antenna for 2.4GHz for BT and WLAN, and a second antenna for FM receive.
