Broadcom has announced a single chip, the BCM4329, that combines 802.11n wireless LAN, Bluetooth and FM radio for use in phones and other handheld devices.
The 802.11n draft standard supports multiple streams of data on a single radio channel using multipath reflections, but this cannot be easily supported on mobile phones. However, there is a single stream option, which increases transfer rates using other parts of the 802.11n standard.
The combo chip will be available in products by the end of 2009.
As well as the usual 2.4GHz band, the chip can support wi-fi in the 5GHz which is less crowded and likely to become increasingly important.
