Would suggest you state the name of your recommended router, that affiliate link only works correctly in US (VPN tested), takes me in UK to "NETGEAR R8000 Nighthawk AC3200" I know that isn't WiFi 6, I own it (bought 2014), and it is AFAIK the very first Tri-Band Router, and not what you intended to link to, which is this one (found by setting my VPN to new York). NETGEAR Nighthawk Pro Gaming 6-Stream WiFi 6 Router (XR1000) - AX5400
Going from Wi-Fi 5 to Wi-Fi 6 is like going from hub to a switch! It’s that big of a jump! If there was one adjective to describe Wi-Fi 6 it’s “ efficiency”. Everything about Wi-Fi six is geared towards efficiency faster speeds are an afterthought. It’s hard to believe that every single standard of Wi-Fi before Wi-Fi 6 your ax point could only talk to one device at a time and it gets the whole channel bandwidth rather it needs it or not! Talk about an inefficiency!!! Honestly Wi-Fi 6 seems to have been created out of necessity because of IOT devices. It’s really a shame that most smart home manufacturers are lazy and cheap, almost none put Wi-Fi 6 radios in their devices!
@ultradeadd I’m not in a job yet, I’ve still got some more university courses to finish. However, I’ve finished all but one of the classes in the cybersecurity program. The last few classes are all related to organizational risk and stuff.
I recently subscribed and I felt the need to comment. Thanks a lot for keeping the videos professional and didactic, in a time when nearly all UA-cam videos seem to be aimed at children with low attention spans, where even scientific and didactic videos have to be filled with jokes, awful editing, sound effects and showing the host making all kind of annoying facial expressions to grab the audience attention, it's quite a pleasant experience to watch a video where I can learn without those distractions, and having such great animations that go straight to the point help to a better understanding. It almost feels like an early 2000s video, back when didactic videos were meant to teach and not entertain. The ironic thing is, this is even more entertaining than those modern youtuber focused tutorials.
Studying to get my foot into IT support and I have to say 9/10 most of the questions I've had have been answered by your videos. Please keep up the amazing work, it's truly appreciated.
A number of manufacturers do not follow the WiFi 6 certification, but are still marked as a WiFi 6 product. The problem here is that they do not follow the Wi-Fi Alliance standard 160Hz from the ax standard (up to 1733 Mbps - 4804Mbps on the shorter 5GHz channel), but instead 80MHz which theoretically stops at 450Mbps. What you have to do before you choose one, if you want to really upgrade the speed at home, is to check in the manual that 160Hz is max. Do not buy anything lower, because then the performance is also worse and you do not really have a real WiFi 6 router.
Your videos are amazing !!! I work in Tech Support with no background in IT or college degree and your videos have helped me soooo much! Keep it up !! :D
Really informative and helpful video. I am an IT helpdesk and still learning new IT technologies. Thank you PowerCert for this upload, very helpful indeed, and your animation is easy to understand. Great work!
lol I've been watching your videos for a few years now. Infact, they're one of the main reasons I got into IT - because they were free to watch. May I ask around what age are you? lol your voice never changes. Thx for the video, I have a router that supports 802.11ax.
Only a few channel are there for such great content. Really appreciate your hard work. Started from the first video and now in the middle of this channel.
Because I understood clearly the explanation, I subscribed--- No frills, no fuzz, just a plain and easy-to-understand narrative. Thank you and stay safe.
I've watched many many tech YT vids and yours are up there as clear, concise and accurate; where you assume the viewer has an attention span greater than a goldfish's. It may help to have dedicated a short section to the client devices and the compatibility needs for them to be also WiFi6 to get the most out of the new Standard. Keep up the great work!
You forgot to mention this also applies to separate access points. With an access point, you can put it in the best location and you can also have more than one, if needed to provide coverage. Many APs can use Power over Ethernet (PoE), so you don't need to have AC power nearby.
This video is a fantastic resource! Thank you so much for creating this! This is very good information, was easy to understand, and I was pleased to learn the benefits of Wi-Fi 6 and Wi-Fi 6E.
My IP provider just sent me a new modem and router (2 piece system). I noticed when my cell phone (Samsung S21 Ultra) connected to the new equipment, it showed a little "6" next to the wifi signal bars. I didn't know what that meant, so I started looking for info to explain it and came across your video. You do a wonderful job explaining it and now I'm super excited to have this new equipment. Thanks 🙂
Clean, clear, crystal presentation and learner digest! I learned more about ICT from you. No need bg music and wild animation. Simple is Best. keep up the good work man!
I just recently got a WiFi 6E network adapter for my PC and we upgraded our modem/router with Xfinity. ( We plan to buy our own very soon ). Before we changed to WiFi 6 I had experienced lag and not so great download speeds. After we got everything updated My PC our speeds improved by a lot and also I have not experienced lag at all. it is the main benefit I am excited about. Playing Call of Duty this is what I experienced: Wifi 5 Latency 150+ms and would even jump often to 400ms up to 999ms for a few seconds Wifi 6 Latency 35ms most of the time. sometimes jumps to 45ms and very rare will go to 50ms. I do not feel any lag. if there is it is barely even noticeable. This is worth every penny.
I bought Wifi 6E network interface card (NIC), but my router / modem is TP link (dual antenna). Do I need to change tp link also? So if that what I need to buy to fully compatibility?
Thank You So Very Much for putting your time and effort into these excellent videos! I found your information on WiFi 6 incredibly interesting and edifying!
As a WiFi technician, thanks for the information about new WiFi standard. Yet there's still other thing needed to consider about WiFi performance: router spesification and distance between WiFi to device. Usually router has limitation about how many devices can connected at the same time with maximum bandwith given by ISP before it's reduced (For example, TP-Link WR840 could handle 3-4 devices for normal usage or 2 devices for streaming usage before bandwith speed archieved by connected device reduced). Depend of spesification given by the manufacture. Distance between WiFi to device also important, some devices can only receive WiFi in a short range while the other could receive it in more extended distance (don't forget if a wall, door, etc. could act as a barrier to WiFi signal).
2.4ghz & 5ghz still having issues of interference from legacy client devices around ( 11n or 11gn or simply with Wi-Fi 5 or Wi-Fi 4 devices around) . You might less throughput having legacy devices around you. MU-MIMO few frames can't understand by legacy clients. Pure Wi-Fi 6 & Wi-Fi 6e network will work well in 6Ghz . Go for Wi-Fi 6e with 6ghz radio having wider channel width with 160Mhz , have lower latency, higher supported data rate, with proper multi channel planning across campus, with MBSSID beacons making faster scan perfect for fast roaming. 6ghz supports multiple channels around 80 in USA. it's perfect for outdoor deployment. Even Wi-Fi 7 forum started for wider and faster wireless network. MU-MIMO works partially well in 6ghz
This channel is such a gold mine on UA-cam! Could you please share me which software tool is used to create such wonderful animations? because I also would like to create contents like you in the future.
Hey thank you for these videos, helping me a lot in my work, it helps to have a clear well spoken and rewindable explanation with these animations just makes it sink in better. Thanks 👍👍👍
Wi-Fi 6 is a high density version of Wi-Fi 5. 5G LTE is a high density version of 4G LTE. High density doesn’t make communication faster. High density allows access points and cell towers to communication with more devices at once. High density also saves power consumption by allowing allowing more devices to be packed into a small space without needing more APs or cell towers. High density is similar to adding more lanes to a road to handle more traffic at once on the same roadway. For more than a decade, all Ruckus Wireless access points have been high density allowing up to 512 devices in the same 300 foot diameter and have also been using OFDMA with Beamforming to improve MU-MIMO capability.
@@gamecubeplayer Regardless of the generation of Wi-Fi to which you refer, you only get the top rate of throughput of any Wi-Fi protocol when BOTH a device AND an wireless access point can negotiate a match with enough channels and fast enough baud rate to meet the top rated throughput of that Wi-Fi generation. Since mobile devices move, that negotiation and communication is always changing. More on that later. Wi-Fi 4 and Wi-Fi 5 access points were 2 channel providing 2x2 which meant 2x2:1 or up to 2 streams out (AP to device) and up to 2 streams back (device to AP) to 1 device at a time. This is SU-MIMO This worked for all smartphones, printers, wireless devices, and laptops of the time. The devices of the time were 2x2 or 1x1, there was rarely ever more than 25 devices on any AP, and the devices rarely conducted more than Mbps of communication, so SU-MIMO was able to keep up. The one major exception for devices was the Apple MacBook Pro which had a 3x3 wireless card. Before Wi-Fi 6 when many APs began using 3x3, the MacBook Pro only used using 2/3 or 1/3 of it’s capability. If you needed full throughput like that needed in Final Cut video editing, one connected to their network via 1Gbps Cat 5 cable. There were virtually no Wi-Fi systems capable of fully supporting the MacBook Pro and the few other other 3x3 devices of the time. Ruckus Wireless R series was the only Wi-fi system that always had OFDMA and MU-MIMO on 3x3:3 and 4x4:4 capable APs during Wi-Fi 4 and Wi-Fi 5. Xirrus also had multiple APs at the time with 3x3:3 and 4x4:4 capability, but they didn’t always have MU-MIMO or OFDMA. They could talk to to 4 devices at once using 1x1, 2 devices at once using 2x2, or 1 device at a time in 3x3 or 4x4. Both Ruckus and Xirrus systems were capable of handling 256 - 512 devices per AP. The way they would be able to talk maintain communication with 512 devices was by installing 2, 4, or more 4x4:4 radios and forcing all devices to use 1x1. The multiple radios using 1x1 allowed these APs to work with 8 or 16 devices at at time. These APS also had 2 or more 1Gbps ports allowing 2Gps or more to be split by up to 512 devices often at 8 or 16 devices at a time. You wouldn’t get maximum throughput, but you could have an HD video playing simultaneously on up to 512 devices at once. You would mainly see Ruckus and Xirrus in auditoriums, stadiums, convention centers, shopping centers, and some hotels where it was common to have more than 100 devices in a 300 foot diameter, the common maximum range around a single AP at the time of Wi-Fi 4 and Wi-Fi 5. The Ruckus and Xirrus APs of today can easily handle 512 or 1,024 devices in that same 300 foot diameter with 8x8:8, OFDMA, MU-MIMO, from 4, 8, or more radios and two or more 2.5 Gbps or 5Gbps multi-gigabit ports to provide that provide near perfect Wi-Fi service and 4k video streaming via current HEIC protocols in extreme high density and extreme interference environments. This is necessary because I and many others carry multiple devices in that same 300 foot diameter circle which may also include digital signage, POS, security, surveillance, access control, climate control, public address, and AV systems which is double, triple, and quadruple the number of devices in the same space only 5-10 years ago. Luckily, high density systems are being standardized now in current communication technologies even in basic home Wi-Fi systems. The same Arris and Motorola that provide home internet communication are now part of Ruckus Wireless. The irony now is that since many smart devices are still 2x2 or 1x1 (printers, smartphones, IOT devices, smart home devices, security cameras, security sensors, digital audio systems, digital signage, security systems, access control systems, public address systems, home automation systems, and such), these devices may see their own maximum throughputs reached, but these devices will never reach the maximum throughput of the AP or the Wi-Fi protocol. Other factors also contribute to less signal throughput. Distance between AP and device, the obstructions between them, electromagnetic interference, and over saturation (too many devices for the AP to handle) are the 4 most common problems one faces in ensuring Wi-Fi quality and reliability. Since the broadcast power of a device is often much less than that of an AP, a device can hear the AP even when the AP can’t hear the device. Mobile devices are often moving with humans (large bodies of water that mitigate wireless broadcasts), so even if the device can maintain connection, the mobile device may never see maximum throughout. Now, almost all wireless systems provide a way to measure signal from AP to device, but at the same time, virtually all Wi-Fi systems fail to provide a way to measure signal quality from device to AP. Again, Ruckus has that covered with an app that runs on devices to test throughput and signal in both directions. Various types of beam forming are used by some APs to improve signal propagation from AP to device, but there are virtually no mobile devices with beam forming to help ensure signal return to AP.
This video was so timely. I purchased a Linksys wifi6 router this weekend knowing nothing about the wifi6 standard. But once it was installed i instantly noticed the speed improvement. Now I know why.
Your content is great as ever.... Can you make a video about WPA3 authentication...? And how it is protecting the handshake which was use earlier in previous WPA versions??
Actually not, wifi 6 is using less energy to transfer data than wifi 4 & 5 bcus its more efficient. The problem the router still expensive and the cheap one is very lackluster. Wifi 6E will use more energy tho. Very confusing naming.
@@kalijasin "You asked about power consumption NOT effective radiated power. Two totally different things." And therefore you wrote max. power supply rating. It is very different thing too. When you have 12V/1.5V power supply - it does not mean it consumes 18 Watts. It can supply 18 Watts at max and consume something like 22W max. (because of efficiency of these small power supplies). Real consumption of these Soho routers is between 5 and 15 Watts - you have to measure it. The reason of power supply (adapter) manufacturer chosen is just about the price, availability or what they have "in the house" (this is nice example of Asus, as they use these 19V adapters for everything and it would expensive to design something new).
Wow very good video! I just Ordered a 6ghz router I have about 20 overlapping networks where I am it's amaizing it works at all, there is nobody on 6ghz according to my analyzer
A couple clarifications are needed. OFDMA seems to serve the same function as MU-MIMO so where is the difference? Also I would love to know how reverse compatibility is handled...Please do a video on how something like Wifi 6 is adapts or is compatible with Wifi 5 devices... In fact the all of the other differentiating technologies could use their own video.
MU-MIMO and Beamforming are working on the same mechanism - sounding null data frames with feedback from clients, so they both are very, very uneffective and properly don't work (still today) - due to high overhead needed for this medium sounding. These technologies try to send different frames to different clients from different transmiters - but in whole channel, minimum 20 MHz. OFDMA works by splitting these 20 MHz to smaller channels and sending data to different clients at once - and hey, OFDMA and MU-MIMO are stackable! Reverse compatibility is handled by trigger frames before OFDMA data frames, these trigger frames promote the medium busy for the length on following data frame, and all other "gears" of protocol are still the same. And remember, that preambles of all data frames are still very slow, very inefficinet and very long - but it gives this great compatibility to Wi-Fi that works years and years back.
@@andrewparamonoff I'm tempted to get a new WiFi-6 router. Our family's iPhones 11 & 13 Pro can take advantage of 803-ax. All our other devices use 803-g,n, or ac. I have a NETGEAR R6400 router that has served well for three years. Thanks for a great video!!
@@zee9276 Just google the phone and specs, the product page for the Mi 11 on Xiaomi's site shows it does do wifi 6. I have around 40 wifi devices at my house, and only my phone does wifi 6, so it doesn't help me much. (I got one anyway because of a sale, it's newer than my old router and has quite a bit better range.)
This is probably the best video I have seen about wifi 6. However, I would like to know what if wifi 5 or older exists on the network. With the carts going to separate devices, can wifi 6 send cards to AX devices while also talking to AC devices or does the entire network completely stop when talking to older devices? I think only in about 2020 did nearly every device like smart TVs and tv sticks and refrigerators supported AC, so it will be another 5-10 years until all devices are wifi 6, not just your new phone and laptop. So will wifi 6 be useful or do you need to wait 10 years until wifi 7 is out for wifi 6 to work?
4:33 Improvement in beamforming? The beams are focused in one or two directions off an antenna, you need to know where they are pointing to benefit from the concentrated beam or you will not have good reception.

Before Wi-Fi 6 when many APs began using 3x3, the MacBook Pro only used using 2/3 or 1/3 of it’s capability. If you needed full throughput like that needed in Final Cut video editing, one connected to their network via 1Gbps Cat 5 cable. There were virtually no Wi-Fi systems capable of fully supporting the MacBook Pro and the few other other 3x3 devices of the time.
Ruckus Wireless R series was the only Wi-fi system that always had OFDMA and MU-MIMO on 3x3:3 and 4x4:4 capable APs during Wi-Fi 4 and Wi-Fi 5. Xirrus also had multiple APs at the time with 3x3:3 and 4x4:4 capability, but they didn’t always have MU-MIMO or OFDMA. They could talk to to 4 devices at once using 1x1, 2 devices at once using 2x2, or 1 device at a time in 3x3 or 4x4. Both Ruckus and Xirrus systems were capable of handling 256 - 512 devices per AP. The way they would be able to talk maintain communication with 512 devices was by installing 2, 4, or more 4x4:4 radios and forcing all devices to use 1x1. The multiple radios using 1x1 allowed these APs to work with 8 or 16 devices at at time. These APS also had 2 or more 1Gbps ports allowing 2Gps or more to be split by up to 512 devices often at 8 or 16 devices at a time. You wouldn’t get maximum throughput, but you could have an HD video playing simultaneously on up to 512 devices at once. You would mainly see Ruckus and Xirrus in auditoriums, stadiums, convention centers, shopping centers, and some hotels where it was common to have more than 100 devices in a 300 foot diameter, the common maximum range around a single AP at the time of Wi-Fi 4 and Wi-Fi 5. The Ruckus and Xirrus APs of today can easily handle 512 or 1,024 devices in that same 300 foot diameter with 8x8:8, OFDMA, MU-MIMO, from 4, 8, or more radios and two or more 2.5 Gbps or 5Gbps multi-gigabit ports to provide that provide near perfect Wi-Fi service and 4k video streaming via current HEIC protocols in extreme high density and extreme interference environments. This is necessary because I and many others carry multiple devices in that same 300 foot diameter circle which may also include digital signage, POS, security, surveillance, access control, climate control, public address, and AV systems which is double, triple, and quadruple the number of devices in the same space only 5-10 years ago. Luckily, high density systems are being standardized now in current communication technologies even in basic home Wi-Fi systems. The same Arris and Motorola that provide home internet communication are now part of Ruckus Wireless. The irony now is that since many smart devices are still 2x2 or 1x1 (printers, smartphones, IOT devices, smart home devices, security cameras, security sensors, digital audio systems, digital signage, security systems, access control systems, public address systems, home automation systems, and such), these devices may see their own maximum throughputs reached, but these devices will never reach the maximum throughput of the AP or the Wi-Fi protocol.
Other factors also contribute to less signal throughput. Distance between AP and device, the obstructions between them, electromagnetic interference, and over saturation (too many devices for the AP to handle) are the 4 most common problems one faces in ensuring Wi-Fi quality and reliability. Since the broadcast power of a device is often much less than that of an AP, a device can hear the AP even when the AP can’t hear the device. Mobile devices are often moving with humans (large bodies of water that mitigate wireless broadcasts), so even if the device can maintain connection, the mobile device may never see maximum throughout. Now, almost all wireless systems provide a way to measure signal from AP to device, but at the same time, virtually all Wi-Fi systems fail to provide a way to measure signal quality from device to AP. Again, Ruckus has that covered with an app that runs on devices to test throughput and signal in both directions. Various types of beam forming are used by some APs to improve signal propagation from AP to device, but there are virtually no mobile devices with beam forming to help ensure signal return to AP.

Tip Top Video!
Clearest explanation I've ever heard on WiFi in general.
Thanks
I love the WiFi thermostat on fire, nice touch
This video was so timely. I purchased a Linksys wifi6 router this weekend knowing nothing about the wifi6 standard. But once it was installed i instantly noticed the speed improvement. Now I know why.
Where can I purchase Linksys Wifi6?
This Wi-Fi 6 is a pretty burning topic on the current period and I have a mediatek-powered TV that supports Wi-Fi 6. Thanks for explaining it.
Thanks for explaining what WiFi 6 is. And nice video presentation. It really helps some of us, see and understand, what is being discussed.👍
Another clear, easy to follow video of something I had a very small clue about.
Video was so easy to understand, that I subscribed.
Do you see the Wi-Fi 6 channel in the SSID? Any details what is need on the laptop or desktop to receive the signal?
Nice video and please upload a video explaining evolution of all WIFI versions
Was thinking about that.
Your content is great as ever....
Can you make a video about WPA3 authentication...? And how it is protecting the handshake which was use earlier in previous WPA versions??
What about Range?
Impact on speed when multiple devices exchanging data simultaneously?
Thanks for explaining in simple layman terms! The graphics are very helpful!
OMG, I literally have a report to write about wifi 6 for my university.. and boom here it is.
Thank you
Thanq so much for making a video on networking plz keep on making video like this i like it so much
Very educational, clear, and helpful illustrations. Thank you, friend. :)
Your explanation is very easy to understand . Great job
Wonderful - as always.. Thanks for sharing.
What about power consumption? Does wifi-6 use more power than wifi-5? Thank you for your videos :-)
Actually not, wifi 6 is using less energy to transfer data than wifi 4 & 5 bcus its more efficient.
The problem the router still expensive and the cheap one is very lackluster.
Wifi 6E will use more energy tho. Very confusing naming.
1:58
It varies.
Wifi-6 routers:
Tp-Link Ax1800 (Archer Ax21) - 12V/1.5A
Linksys Ax3200 (E8450) - 12V/2A
ASUS AX1800 (RT-AX55) - 12V/1.5A
Wifi-5 routers:
Linksys EA7300 - 12V/2A
Linksys EA7500 12V/3.5A
Netgear Nighthawk R700 - 12V/3A
Asus Rt-AC88u - 19V/2.37A
Note: You asked about power consumption NOT effective radiated power. Two totally different things.
@@kalijasin "You asked about power consumption NOT effective radiated power. Two totally different things."
And therefore you wrote max. power supply rating. It is very different thing too. When you have 12V/1.5V power supply - it does not mean it consumes 18 Watts. It can supply 18 Watts at max and consume something like 22W max. (because of efficiency of these small power supplies).
Real consumption of these Soho routers is between 5 and 15 Watts - you have to measure it.
The reason of power supply (adapter) manufacturer chosen is just about the price, availability or what they have "in the house" (this is nice example of Asus, as they use these 19V adapters for everything and it would expensive to design something new).
Wow very good video! I just Ordered a 6ghz router I have about 20 overlapping networks where I am it's amaizing it works at all, there is nobody on 6ghz according to my analyzer
I really love your videos man!
Great explanation , i have used this to expakinb to my clients how the wifi works
A couple clarifications are needed. OFDMA seems to serve the same function as MU-MIMO so where is the difference? Also I would love to know how reverse compatibility is handled...Please do a video on how something like Wifi 6 is adapts or is compatible with Wifi 5 devices... In fact the all of the other differentiating technologies could use their own video.
MU-MIMO and Beamforming are working on the same mechanism - sounding null data frames with feedback from clients, so they both are very, very uneffective and properly don't work (still today) - due to high overhead needed for this medium sounding. These technologies try to send different frames to different clients from different transmiters - but in whole channel, minimum 20 MHz. OFDMA works by splitting these 20 MHz to smaller channels and sending data to different clients at once - and hey, OFDMA and MU-MIMO are stackable! Reverse compatibility is handled by trigger frames before OFDMA data frames, these trigger frames promote the medium busy for the length on following data frame, and all other "gears" of protocol are still the same. And remember, that preambles of all data frames are still very slow, very inefficinet and very long - but it gives this great compatibility to Wi-Fi that works years and years back.
@@andrewparamonoff I'm tempted to get a new WiFi-6 router. Our family's iPhones 11 & 13 Pro can take advantage of 803-ax. All our other devices use 803-g,n, or ac. I have a NETGEAR R6400 router that has served well for three years. Thanks for a great video!!
@@Bippy55 how to find out if my phone is compatible with wifi 6 or at least close? I have Xiaomi Mi 11
@@zee9276 Just google the phone and specs, the product page for the Mi 11 on Xiaomi's site shows it does do wifi 6. I have around 40 wifi devices at my house, and only my phone does wifi 6, so it doesn't help me much. (I got one anyway because of a sale, it's newer than my old router and has quite a bit better range.)
@@michaeldmorrison 40?!!??!
Just when I was considering to buy one, you posted this video )
:)
You have made an excellent video. Keep it up
Very useful video ..do more videos on wireless technology..thanks in advance 😀
Long time waiting you :)
Great video, quickly explained everything very well. Thanks!
Probably learned more here than any of my tech classes in one 8 minute video lol.
Thanks for the videos. Excelllent channel.
I am weirdly extremely excited to watch this😂
I also thank you for this video that helped me to better understand the capabilities of my Wi-Fi 6 router.
Great video! Super informative. Thank you very much.
Thanks for the refresher!! Great video.
This is probably the best video I have seen about wifi 6. However, I would like to know what if wifi 5 or older exists on the network. With the carts going to separate devices, can wifi 6 send cards to AX devices while also talking to AC devices or does the entire network completely stop when talking to older devices? I think only in about 2020 did nearly every device like smart TVs and tv sticks and refrigerators supported AC, so it will be another 5-10 years until all devices are wifi 6, not just your new phone and laptop. So will wifi 6 be useful or do you need to wait 10 years until wifi 7 is out for wifi 6 to work?
Nice thanks for explaning in detail
please tell me which software u r using
I really like your series of tech videos. Have you done one on VPNs?
Another great video with the latest info. Who needs expensive books. Thank you😊👍.
Great video and simple explanations.
Nice and helpful video, great explanation.
4:33 Improvement in beamforming? The beams are focused in one or two directions off an antenna, you need to know where they are pointing to benefit from the concentrated beam or you will not have good reception.
Great content. So simple. I’m not afraid to say it. I love you.
