Companies building 802.11ac products don’t have to implement beamforming, but if they do, they must do so in a prescribed fashion. The IEEE didn’t make the same mistake with the 802.11ac standard that’s in today’s high-end devices. Some vendors developed pre-paired 802.11n kits (with Netgear’s WNHDB3004 Wireless Home Theater Kit being one of the best examples), but such kits tended to be expensive, and they never had much effect on the market. Used a different implementation, beamforming wouldn’t work. The router you bought might have employed one technique, but if the Wi-Fi adapter in your laptop First, a bit of background: Beamforming was an optional feature of the older 802.11n wireless networking standard, but the IEEE (the international body that establishes these standards) didn’t spell out exactly how it was to be implemented. Fortunately, beamforming is finally becoming a common feature in 802.11ac Wi-Fi routers, at least at the high end. Instead of broadcasting a signal to a wide area, hoping to reach your intended target, why not concentrate the signal and aim it directly at the target? Sometimes the simplest concepts are the most difficult to execute, especially at retail prices. Simple that you wonder why no one thought of them before.
