Don't look now, but the speedy WiFi router you just bought may already be old hat. Huawei has tested WiFi based on a future standard (802.11ax) that can hit 10.5Gbps -- about 10 times faster than what you typically get out of an 802.11ac connection today. The trick, the company says, is making more efficient use of the airwaves. The new technology is smarter at allocating wireless spectrum, juggling data between multiple antennas and cutting back on interference. Huawei doesn't even have to switch to ultra-high frequencies to make the magic happen; its approach works on the same 5GHz band that many WiFi networks already use.
