Dope Tech Episode 2

<<@b.c.academy7151 says : Watching how wifi works using wifi😅>> <<@yigajonathan4744 says : I also have an idea,maybe a video explaining Wireless Access points would be nice . Also explaining Mesh WiFi systems>> <<@yigajonathan4744 says : I have really loved this video,am gaining alot of knowledge>> <<@hanoksworld says : Thanks for the clear explaination>> <<@zazugee says : good to know, i found out that file transfer in my N router LAN was as slow as my DSL when i used a 10year old laptop and raspberry Pi5>> <<@weevilgaminghi says : That's so nice 👍 to find out that Hawaii introduced a working WiFi concept first. Makes me proud. Much like learning that Hawaii was the first to have lights in a capital building. Iolani palace had light first before the white house.>> <<@leskaighin8903 says : A fascinating insight>> <<@steve7720 says : 802.11ad and 802.11ay should be included and used more. Not many people know about them.>> <<@DANJONPEARCE says : great vid>> <<@ahmadabuazoum6015 says : Thank you for share>> <<@Anonymous51701 says : Didn’t know John Lennon knew computer stuff too>> <<@TheRealHaloCorps says : This channel gives me Bletchley Park vibes. Subscribed.>> <<@wisteela says : Extremely informative>> <<@johngangemi1361 says : Great video Chris!>> <<@burgermeister7244 says : I swear, Chris. Your videos are great. I've said it before but I'll say it again: I'm a huge fan.>> <<@r0galik says : Very nicely explained>> <<@SBPepperminion says : 1:05 It should've been called IE³ for simplicity at the time.>> <<@genericelaf1007 says : You always make amazing videos. Thanks>> <<@gkossatzgmxde says : I would have liked more info on how the bandwidth degrades with users accessing a single access point, e.g. in a full coffee shop.>> <<@ZijZijnZijnZoons says : Great introduction to WiFi! Thanks for the info!>> <<@whoever2838 says : so wifi direct is pretty much Bluetooth but consume more power?>> <<@monkeypoohonyou says : Top class research and explanation. Amazing work as always!>> <<@techrescuestl says : veryvery helpful. Well done, Chris!>> <<@lindaoffenbach says : A tad late to this but astonishing well clarified once again 👌>> <<@jerrystraight4916 says : Very informative! Good Show! Explains a lot. Now using my 'AC' WIFI Dongle instead of the 'N' Wifi Card lol card was very slow it runs at 144 MBPS{WIFI 4) and the 'AC' Dongle(WIFI 5) runs at 433 MBPS. Can't wait for wifi 6>> <<@dcc1165 says : YAFIV (Yet Another Fabulous and Informative Video) :). I've been in the WiFi game since it game out (with those ugly antennae you'd have to connect to the back of the laptop screen) but the content in this video has really filled in the blanks as to "what came when and how did it all evolve". Keep this content coming...even though most of us who subscribe are familiar with the topics of your videos, your content makes knowledge more thorough and therefore, more valuable. Keep up the great content!!>> <<@oneeyedphotographer says : WEP was always weak, it could be broken in a usefully short period of time, and then someone found a much faster crack to the extent it kept only the nice guys out.>> <<@HomeForTheLDly says : i came because i was hoping you would explain why it is wifi frowned upon so much on when it comes to gaming. but i'm excited to learn about wifi 7 in 2024,, so not all bad>> <<@nebyounce3523 says : Great video! Learned alot>> <<@itai90f11 says : A mustache would look good on you Chris>> <<@kirkleadbetter1093 says : So if building a house in the next few years, does it make sense to wire with ethernet cabling, or just go with wifi?>> <<@temyraverdana6421 says : Thanks, a very useful lesson>> <<@modoc852 says : No, cont listen to another frickin limey>> <<@srvuk says : An excellent breakdown that will demystify some aspects for many who are not interested in intricacies.>> <<@matthewday7565 says : There were also a few non-standard implementations, now insignificant, such as a wide channel 22 mbit mode derived from 802.11b and a similar excursion of "Super-G" derived from 802.11g. One complexity of using multiple standards together is that some equipment can be set to "Greenfield Mode", which turns off support for older protocols, which MAY improve throughput if they are not required and not present on the channel from any nearby networks. The problem with greenfield mode, is it removes the protective wrapper of lower speed busy signalling around higher speed traffic, so conflicts may occur if lower standards are present on the channel from another network>> <<@Girder3 says : Hoping for a video on Bluetooth generations soon.>> <<@darrennolan3332 says : Great video Chris. I wonder would you be able to do something similar about the evolution of the Bluetooth development. Thanks again for the great work you do.>> <<@Alias_Anybody says : The funny thing with all the LAN, WLAN and USB standards is that for me the limiting factor is still ALWAYS the speed of the network itself, never router to network card, network card to CPU or CPU to RAM/disk. Like frick, why is internet still so bad in many places on this planet?>> <<@abhijeettiwari1 says : Can u make a video on how compiler or interpreter works>> <<@dktr_SP4OX says : Nothing dumber than those Wifi names 4, 5, 6 they came up with. Instead of such nonsense, it should be something like 'AC 160MHz 2x2' or 'N 40MHz 1x1,' and you immediately know what's going on, instead of some numbers for idiots.>> <<@robinbrowne5419 says : Very interesting. Thank you. I always wondered what all those numbers and letters meant. PS - I did what you said and looked at the Properties of my wifi connection and it says I am watching you on WPA2. So if I have learned anything from your video, that means I am on Western Pennsylvania Atlantic channel 2. Lol. Cheers :-)>> <<@SourojitBh says : Awesome presentation, thanks a lot!>> <<@davidunwin7868 says : Good video. I've been using WiFi since 2004 and I've always found consumer grade equipment (eg a modem/router/WiFi AP all in one) to fail after a year or two and need to keep rebooting it. Or if doing a large data transfer over WiFi, the router will crash. I've given up on consumer grade gear and now invested in business-level gear for home network (specifically TP Link Omada). I've been running for a year on it without any problems. You get what you pay for.>> <<@AndersJackson says : Link-local IPv6 network address are not needed to be secret. Not compared to public IPv6 addresses.>> <<@sameerGhs says : all 802.11AC wireless cards support both 2.4 and 5 ghz bands>> <<@GizmoFromPizmo says : When we built our house back in the late 1990s, I thought I was the coolest nerd ever because I had the house wired for 1Gb Ethernet (Cat. 5e). Now days, it would be foolish to go to that added expense when you can simply put up an 802.11 Access Point or repeater. All my iSCSI connections are via wired Ethernet but I have a couple network devices untethered (printer and tablet).>> <<@timanderson5723 says : Your choice of presenting colorful items on a white background is awesome.>> <<@andrewwalsh531 says : A great explanation of wifi standards & generations, thank you! It's always a source of frustration for me how little throughput my home network seems to achieve, though I have hardware capable of much higher performance. Determining for certain the bottlenecks, ie., A) my service provider, B) my broadband router, C) my wireless router, D) my client devices, or E) all of the above......I really need to sharpen my skills in this area :)>> <<@adrianwilliams763 says : Excellent and informative>> <<@CypherOzzie says : https://www.nma.gov.au/defining-moments/resources/wi-fi#:~:text=In%201992%20the%20first%20Australian,technology%20from%20CSIRO%20in%201997. In 1992 the first Australian WLAN patent was filed for, the US patent was filed for in 1993 and approved in 1996. This led to the creation of prototypes and the founding of Radiata Inc by Dave Skellern and Neil Weste from Macquarie University. They took out a non-exclusive patent on the technology from CSIRO in 1997.>>
