3:06 is a bit misleading, technically beam forming does refer only to the directional transmission, but the same array of antennas can and does achieve directional gain in receiving, via maximum ratio combining. That basically means that while your client is not transmitting a stronger signal in the direction of the router, the router is "listening" in the direction of the client, and receives it stronger than it receives interference coming from other directions.

One of the main reasons why most optimizations focus on the access point and not the client, is because it is easier to deal with RF on the AP side due to fewer space and power constraints. For example, most smartphones have negative gain antennas (signal is sacrificed for more aesthetically pleasing antenna lines or other reasons). Due to the limitations and compromises on the client side, the AP can make up for it by broadcasting at 1 watt, thus a brute force method, and then beamform to further improve SNR. Since the mobile device cannot have a WiFi radio constantly pulling a wall, you may see transmit powers more in the 100mw range. Since the access point does not have significant limitations on size (such as a smartphone where they may want the WiFi radio to only cover 5 square millimeters), the access point can use a far better LNA and a signal path in general that prioritizes SNR. This is why AP makers moved to using higher transmit powers even as client devices stayed at really low transmit power levels. Think of it like a bat that can speak extremely loudly having a conversation with a human that speaks softly.

This becomes more feasable with higher frequencies, because antenna size also gets smaller and more antennas can be fitted inside the router. So it's more for the new 5GHz wifi, and it's also used in 5G.

You mention the donut shape you get from an antenna, but that's true of a single antenna broadcasting alone. If you have 2 antennae broadcasting simultaneously, they alter the shape of the signal from a donut, squeezing and stretching it. If they are parallel, the shape becomes a figure 8, centered between them. So, if your router has those 2 sticking up, but they can be laid flat out from the back of the router, and it is in the middle floor of a multi-floor structure, you'll be pointing that figure 8 up and down, which will cover more floors better than them standing straight up. I've used trickery like that to help focus the coverage of routers. Oh, and when people splay them 'fashionably' as the package often shows, especially on triple antenna layouts? Just all bad.

beam forming changes the convergence points not really the radiation or polar pattern moving closer to the AP could actually cause a momentary drop in signal as the waves arrive off axis from each other until it compensates, another technology, beamflex actually dynamically changes the polar pattern. But beamflex if implemented properly in the client can improve performance in both directions (as can beamflex).
@nikolausluhrs

@@uriahheep6730 I think we may be using different types of beam forming. What I meant is the method used in phased arrays which uses the phase shift in the signal to adjust the interference patterns into a more directed far field pattern. For wifi far field should start at most a foot away from the acess point. Theres some really good videos showing the steering of the beam based on relative phase of multiple transmitters. If you do it right you can have multiple beams sent at the same time which is super cool. But yeah like they said in the video its not really a thing in home wifi right now. It is however very much a thing in cellphone towers. Its a big part of what allows cell service to work at all.

Beam forming works much like phased array radar. It generates signals so that the interference is constructive ( stronger signal) at the location of the device. This does not mean that that would be the only point at which the interference is constructive, and it for not mean it is destructive everywhere else. This lets the receiver get the best possible signal, and while not eliminating interference from other wifi devices in the area it will substantially improve the signal to noise ratio for it.

Actually, ruckus has something called beamflex. It doesn't work at all like you've described. It uses actual directional antennae to actually direct the signal, not "sort of" bias a signal in a certain direction like with generic ac beam forming, which just works on the principle of phase rotation. A ruckus AP with beamflex will send beacons and answer probe requests in an omni directional way (like a normal AP), but it will then switch to directional for further communication. On average, we see a 3db gain, which is a doubling of the rssi. It can switch antennae (or combinations) on a per packet basis. You can see a pic of the inside here: webresources.ruckuswireless.com/datasheets/r610/ds-ruckus-r610-de.html Sorry, but you're just wrong.
