Signal Measurement: The router measures the signal strength of the device at various angles, determining the best direction to enhance signal transmission.
-
Signal Direction: Instead of sending data in all directions, the router focuses the signal towards the identified device, creating a more stable and robust connection.
-
Continuous Adjustment: As devices move or change locations, the router adjusts the signal direction on the fly, ensuring optimal performance at all times.
Types of Beamforming
There are two main types of beamforming:
-
Explicit Beamforming: This method requires both the router and the connected device to support beamforming. The router and device communicate to determine the best transmission path and settings.
-
Implicit Beamforming: This technique can function with devices that do not explicitly support beamforming. The router uses its antenna array to estimate the location of connected devices and optimize signal paths accordingly, although this may not be as effective as explicit beamforming.

What is WiFi Beamforming?
WiFi Beamforming is a technology used in wireless networking that focuses the transmission of data towards the specific location of connected devices rather than broadcasting it uniformly in all directions. This targeted approach helps improve the performance and efficiency of WiFi networks. Essentially, instead of sending signals out in a broad area where some may go unused, beamforming enables the router to direct its signals more precisely, enhancing the quality of the connection.
As a result, devices that support beamforming can experience stronger signals, reduced interference, and improved range. It is particularly beneficial in environments with multiple devices connected, as it helps in optimizing the data transfer to each device individually, rather than treating them as a collective group. By utilizing beamforming, users can enjoy a faster and more reliable wireless experience.
How does WiFi Beamforming work?
WiFi Beamforming works by using sophisticated algorithms to locate connected devices and then adjusting the direction of the wireless signals based on those locations. Routers equipped with this technology can identify the position of devices in real-time, which allows them to “form” beams or directional signals toward those devices. The router takes into account factors like distance, obstacles, and device sensitivity to optimize signal strength.
These adjustments are made dynamically, meaning the signals can change direction as devices move or as new devices connect to the network.
