Broadcom over the weekend introduced its latest consolidated multi-wireless chips, a combination of Bluetooth 4.0 and the forthcoming 802.11ac, which offers more than twice the speed of existing 802.11n technology and yet is up to six times more power-efficient handling the same amount of data. The new chips can also handle FM and conventional 802.11 2.4GHz and 5GHz bands, and are expected to debut in early 2013 for use in smartphones and tablets.
