The real world result is 802.11ac not only enables you to enjoy the fastest 100Mbit (and beyond) fibre optic broadband speeds all over the house, but to enjoy it along with multiple streams of Full HD content, super low latency gaming and blazing fast home networking all at the same time. By contrast Linksys’ own EA4500 (identical except being limited to 802.11n) managed 10.6MBps (84.8Mbit) dropping to 2.31MBps (18.48Mbit) under the same conditions.

This was most clearly seen with the Linksys EA6500 which hit speeds of 30.2MBps (241.6Mbit) when connecting to a device just two metres away, but still performed at 22.7MBps (181.6Mbit) when 13 metres away with two solid walls in the way. The combination of these two technologies is profound. This technology has been around in proprietary form (it made a huge impact in the D-Link DIR-645), but now it will be inside every 802.11ac router and every 802.11ac device. Rather than throw out wireless signal equally in all directions, WiFi with beamforming detects where devices are and intensifies the signal in their direction(s). The second key factor is 802.11ac makes ‘beamforming’ a core part of its spec. 5GHz is also necessary to support the faster speeds of wireless ac. This more than counters the fact that, in lab conditions, 5GHz signals do not actually broadcast as far as 2.4GHz signals. While some more modern routers broadcast 802.11n in 5GHz as well as 2.4GHz they remain relatively rare.Ĭonsequently, the 5GHz spectrum tends to be ‘quiet’, meaning much less interference from neighbourhood Wi-Fi. The first point to make is the 802.11ac standard lives entirely in the 5GHz spectrum. While speed is what will likely sell 802.11ac routers, range is equally important. It is a marketing ploy where the manufacturer has added the 1.3Gbit theoretical maximum speed of 802.11ac to the 450Mbit theoretical maximum speed of 802.11n. In addition no 802.11ac router released so far has packed more than six antennas.Ī final point: beware routers claiming speeds of 1,750 Gigabits. Smaller devices like smartphones tend to fit only a single antenna, but it gets even bigger in tablets (typically two to four antennas) and laptops and televisions (four to eight). Wireless 802.11n supports a maximum of four antennas at roughly 100Mbit each, where 802.11ac can support up to eight antennas at over 400Mbit each.

Happily this gain is likely to increase as 802.11ac devices advance. So 2.5x faster when close to your router is a good rule of thumb (though far more at distance, which we’ll come to shortly). In our experience wireless n performance tends to top off around 50-150Mbit and our reviews of draft 802.11ac routers have typically found performance to be closer to 250-300Mbit. These figures are ‘theoretical maximums’ that are never close to being realised in real world scenarios. So wireless ac is roughly 3x as fast as wireless n? No. It is vastly quicker than the 450Mbit per second (0.45Gbps) headline speeds quoted on the highest performing 802.11n routers. This translates to 166 megabytes per second (MBps) or 1331 megabits per second (Mbps). With any new wireless technology speed is always the headline-grabbing feature but, as with every wireless standard to date, the figures tossed around can be highly misleading.ġ.3 gigabits per second (Gbps) is the speed most commonly cited as the 802.11ac standard. That said you will need both an 802.11ac router and an 802.11ac device to enjoy the standard’s biggest benefits.

Similarly you can upgrade to an 802.11ac router and it will work happily with all your existing devices. This means you can buy an 802.11ac-equipped device and it will work just fine with your existing router.

The first thing to get out of the way is – like past Wi-Fi standards – 802.11ac is backwards compatible with 802.11b, g and n.

Video: How to improve your home’s Wi-Fi network As this standard is built into routers, laptops, tablets, smartphones, televisions and much more we look at what enhancements it will bring over its predecessor, 802.11n, and whether it is worth getting excited about. Last week governing body the Wi-Fi Alliance certified the ‘802.11ac’ standard, paving the way for the mass roll-out of ‘wireless ac’ devices. What’s the difference between 802.11ac and 802.11n? We explain the ins and outs of new-gen and last-gen Wi-Fi standardsī, g, n, ac… wireless standards haven’t had the most logical of alphabetical progressions, but it has just had the most important.
