Broadcom’s BCM4335 chip will be available in Q1 2013 for mobile and other small devices. Among other things it provides the latest Wi-Fi speed improvement by supporting the 802.11ac amendment to the wireless networking standard.
Low power Bluetooth and better battery life will allow users of mobile devices to leave Bluetooth running for longer. This makes connecting to Bluetooth beacons to find indoor location viable. Unfortunately the discovery phase of the Bluetooth protocol is slow limiting its usefulness as the device moves quicker.
Broadcom has announced their BCM4752 chip with support for 802.11ac and low-power Bluetooth. Naturally the new chip is smaller and uses less power.
