@bobbaberson3654 2 года назад

Dear Iain, these are all amazing videos. It is really tough to condense such complex material into short videos but maintain understandability of the it. This is really appreciated. You mentioned radar a couple of times. Do you have any plans to make a basic lecture on that? Maybe just simple doppler/ToF/AoA extraction or maybe something on MUSIC algorithm. I have been searching for a while for a decent explanation of MUSIC but it is hard to find one.

@iain_explains 2 года назад

I'm glad you like the videos. Thanks for the suggestion of a radar and MUSIC topic video. I'll add it to my "to do" list.

@iain_explains Год назад

... I just came across this comment again. I've now made a few videos on Radar, and plan to make more. I guess you may have seen them by now, but if not, then the ones I've done so far are: "Why is a Chirp Signal used in Radar?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Jyno-Ba_lKs.html , "What is a Stepped Frequency Radar Signal?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6JVGb3KpVqs.html and "How does a Radar Track Manoeuvring Targets?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ibvlKTGQ4zQ.html

@robertharvey6725 11 месяцев назад

Great explanation. I expect that by changing the delay one could cause the beam to sweep.

@iain_explains 11 месяцев назад

Yes, that's what's called Adaptive Beamforming.

@fifaham 3 года назад

Thank you Iain. Beam forming is an Amazing principle. So by adding multiple antennas (n Antennas) and injecting a delay circuits and adders we can form those shaped zones and select which receiver to have the best reception from specific direction. I imagine that if we have a programmable delay circuits with algorithm to control those delays and selecting the proper antennas then we can control those beams. Is that what is used in space division multiple access? We maybe able also to have intelligent algorithm that senses the RSSI levels, provide feedback to apply combinations of selecting antennas, adders and delay circuits and eventually automatically select the sending location. I wonder if such a thing already exists?

@iain_explains 3 года назад

Yes, that's right. It's exactly what happens in MU-MIMO. The process you've described happens in the matrix operations in the receiver (for receive beamforming) and the transmitter (for transmit precoding). See "What is Multi-User MIMO Communications (MU MIMO)?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0ncIWlhsu1A.html

@CanadianPranks12 Год назад

Interesting facts

@eightysevenmoore 8 месяцев назад

So… I created a machine monitoring daq using LabVIEW, mics and NI cRIO’s… about 4 months into monitoring a dyno i intuitively came up with this concept not knowing I stumbled upon beam forming by looking at hundreds of high speed wave form data… Thank you sir for plainly consolidating my mad-ness!

@markcraddock803 Год назад

Thanks a ton Ian. Not what I thought beamforming was. Excellent explanation of the theory of beamforming. Do you offer any in house training?

@iain_explains Год назад

I'm glad you liked the video. I'm not offering in-house training or tutoring at the moment, but potentially will in future. For now, the videos will have to do. Please do let me know if there are particular topics that you'd like to hear more about if I haven't covered it so far. Check out my web page which shows a fully categorised list of the videos: iaincollings.com

@BartomiejZogaa 6 месяцев назад

Thanks for explaination, now I'm wondering how the transceiver actually tunes to specific wireless client by selecting right delays?. Is it still in PHY or MAC layer ? Also how fast is the switching ? As if we have 4x4 router and two typical 2x2 clients how router assures signal from 3rd device will be still handled without comprising value added of two existing MU-MIMO clients?

@Ulrich.Bierwisch 2 года назад

I know beam forming from acoustic cameras that are using an microphone array to create a picture where you can see the source of noise. This allows to analyze what part of a machine, car, plane and such is emitting what noise. Might be a topic for another video.

@iain_explains 2 года назад

Thanks for the suggestion. I'll add it to my "to do" list.

@marcinrybakowski8926 Год назад

Great explanations. Is it possible to visualize near field beamforming (beam focusing) in similar way?

@iain_explains Год назад

Yes, but in that case the delays are not constant between different antenna elements.

@flyingpinguu 3 года назад

Thanks this made me understand it better! It still left me with a question though. If you look at an angle such that the phase shifting is exactly a whole period, the waves will still add up constructively there. How is it made that these side maxima are so weak in phased array antennas?

@iain_explains 3 года назад

Yes, that's a good observation. This effect depends on how far apart the antennas are spaced. Check out this video for more details: "How does Antenna Spacing affect Beamforming?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-amepyf9-E1w.html

@CrazyDBS Год назад

hello, I'm from Brazil and I wanted to know if beamforming also improves latency/ping in online games, thanks

@AetherXIV Год назад

great explanation. Now my question is... will this increase a person's exposure to harmful EMF?

@standardcoder1184 Год назад

6:40 Shouldn't that be 3 time the delay (and not twice) if we want the signal from non-equatorial source?

@j.jester7821 Год назад

I found implicit beamforming on netgear router actually adds a 200- 400 ms of latency. unacceptable.

@deepinmoutain Год назад

Thank you very much for the explanation. I have a question. Antennas are fixed on a wireless device. So, the distance between antennas will be the same. How does it work for different frequencies?

@iain_explains Год назад

Excellent question! The form of beamforming that maximises SNR (that I describe in this video) is inherently narrow band. In practice it doesn't have to be exactly half a wavelength separation, and there are approaches to designing beams that are wide band, but they come with a performance penalty in terms of SNR.
