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.
That was awesome! I knew nothing about beamforming. Makes me think of other Home network stuff that might be cool as well. Base2 ethernet stuff (MoCA and powerline ethernet) seem to come up as questions a lot as do mesh networking and the value of backhaul for multiple node households (which seem to be most of them lately). Another one that seems to come up is WiFi appliance age. Some devices seem to get less reliable as they get older.

2:33 Maybe when talking about optionality of beamforming in 11ac "Wi-Fi 5" you should not try to illustrate with mandatory beamforming of 11ax "Wi-Fi 6" with MIMO clearly defined… 2:44 Or you could google-up its model number before purchasing or scanning its signal with Wi-Fi info app on your phone before checking out off the store.
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.
Don't be so negative. In my flat one new WiFi-ac AP with beamforming (price about 105$) resolved all problems with blind spots, that can't be fixed even with 3 older WiFi APs. Meassured real speed is at 94/95 Mbit which is almost the maximum of internet connection I get (100/100) at the edge modem :)
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).
@@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.
for omini directional antenna, the direction that your antenna pointing to has the least signal strength. And many home wifi routers' antenna is just deco
Good explanation about a technology I never really understood. Now it makes sense and I won't be using it any time soon anyway. My internet is more than adequate at my apartment. (:

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.
Wasn't this method used way back in the 1990's that those Radars of Jet Fighters had as it was called Electronically Scanned Array? In which multiple antenna arrays can form beam scans much similar to the "beamform" router. Huh, it's just now that they decided to use the tech.
How about a smart aiming device? Like actual aiming, with a motor to turn around and all that? That must work wonderfully well i suppose, 2 antes shoud do the trick, on for signal transmission, another to find out to where it shoud aim the actual data transmission antenna..well both will transmit but still, u get the idea...one is the beam the other just the gessing haha

Wait. so "Beamforming" is more like "optimize interference at specific position" and not " delete waves everywhere else and only project the frequency in a general direction? So Beamforming, like the name suggest does NOT provide Spatial Division for reuse of frequencies?
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.
why nobody mentions the length of the wifi wavelength that is 12.5 cm and in which space you can adjust the place of a device to archive maximum performance of the transmition ? at least mention it , even in inches (about 5 ) .
maybe dont use a dipole omni antenna and just use a parabola thats actually directional also beamforming is military radar tech originally (phased array)

Holy crap this video hurt, this is only about half right. While transmit beamforming may make literal sense, there absolutely is receive beamforming, think about how old rabbit ear TV antennas worked, adjust (beamform) to receive a better signal.
