Beamforming provides help under in certain environments for devices that support 802.11ac.
In the real world, 802.11ac will most likely be known for its ability to offer quicker speeds at the range. 802.11ac accomplishes this by using the 5 GHz frequency, up to 160 MHz bandwidth, and a technology called Beamforming. Put simply, a router and a device (phone or laptop for example) that both contain Beamforming technology will seek one another out. This drastically increases data throughput between the two devices, whilst also lowering power consumption (the transfer will take less time).
The Razer Sila can “point” its antenna arrays at a client to provide better reception, range, and throughput while minimizing interference. This technique is known as explicit beamforming.
Explicit beamforming has existed for some time but was difficult to use because many manufacturers used different, incompatible versions. IEEE 802.11ac standardizes explicit beamforming technology so that routers, access points, and wireless clients from all conforming manufacturers can use the technology's full capacity. Explicit beamforming only applies to devices that are operating in the 5GHz bands.
Explicit beamforming can be controlled by the mobile app, under the "Advanced Features" section, or by a web browser, under "Wireless Configuration".
