In as much as the technology itself is rather impressive speed wise, there seems to be quite a few hurdles that still need to be overcome before this technology has a chance to win over consumers and business alike. The good news is that it seems to be sufficient with three antennas on the receiving end, but the transmitter at this stage is using no less than sixantennas.

If 802.11ac is going to be developed this way, then it means that Wi-Fi as we know it is going to turn asynchronous, something we have a feeling quite a few users aren't going to be too keen on. On top of that, speeds at Gigabit level are currently only being achieved to a single receiver, whereas in a three user scenario the speed was dropped to an effective throughput of 120Mbit/s per user. This is still better than the current 802.11n standard, but far from ideal in a multi-user environment, something that Wi-Fi almost always is.

We're also moving to wider and wider data channels and the 802.11ac standard will move from the 40MHz per channel of 802.11n to 80MHz per channel. The 802.11ac standard is said to be ratified by 2013, so luckily there's still some time to work out the kinks. Faster Wi-Fi sounds like a great thing, but it almost seems like there's a need to come up with a better way of sending the radio signals, as we can't see a lot of router makers going down the route (no pun intended) of adding six antennas to their devices.
