Faster Wi-Fi tech rumored to be arriving on Macs in 2013

Apple's next round of upgrades to its Mac computers are rumored to include a new, faster version of the ubiquitous 802.11 Wi-Fi spec.
Citing sources, The Next Web says Apple is working with Broadcom to include 802.11ac Wi-Fi technology in its Mac lineup, a move that would increase wireless networking speed when used with 802.11ac routers.
The 802.11ac Wi-Fi standard, which Broadcom has called "5G Wi-Fi," supports up to three streams and speeds of up to 1.3Gbps on the 5GHz band. That speed is dropped down to 450Mbps over a three-stream version
