New Macs Getting 802.11ac?

Posted by Sam Churchill on

TheNextWeb says Apple’s 2013 Mac lineup will feature 802.11ac networking using Broadcom’s “5G” WiFi chips. Broadcom’s BCM4335 integrates a complete, single-stream 5G WiFi system – with Bluetooth 4.0, FM radio and software – on a single silicon die.

Mac products currently offer 802.11n connectivity, providing connections up to 450Mbps with three antennas. The 802.11ac standard, which uses the 5 GHz band exclusively, can deliver up to 450Mbps for one antennae and up to 1.3Gbps via three antennas.

The 802.11ac standard, also known as 802.11 VHT (Very High Throughput), uses the existing 5 GHz Wi-Fi band with wide 80 MHz or 160 MHz channels, improved modulation, and simultaneous multi-user MIMO for throughputs above 1 Gbps. Broadcom’s BCM4335 supports 20, 40, and 80 MHz channels with integrated support for Wi-Fi Direct and Miracast.

Broadcom announced their first 802.11ac chipset at last year’s CES, and in July, their chips for use in smartphones, tablets, and ultrabooks. Those chips should start hitting the market in the first quarter of 2013. Broadcom was the first chip vendor to sample 802.11ac chips and is now shipping devices for use in laptops and routers.
