I am an old guy and a scientist, but have always kept up with technology. When bluetooth was being developed it was featured as a “personal” networking protocol. It then took a relatively long time to roll out. Bluetooth, by the way, was King Harald of Denmark, who unified the Danish tribes and was a big fan of blueberries. His subjects nicknamed him blue tooth!
Thanks you, I didn't know where the name originated. Wikipedia states "The first wire recorder was invented in 1898 by Danish engineer Valdemar Poulsen, who gave his product the trade name Telegraphone.".
Beautiful animation with a great explanation. However, you forgot to mention that modern Bluetooth protocols now require some sort of passcode to pair certain devices. I believe this is just a security measure to avoid unwanted, unauthorized or unrecognized Bluetooth connections from happening between certain devices.
since first video I've ever watched in this channel, I always feel, I should travel through time & show these videos to college lecturers & professors for better training.... thank you Sir (team) for making our lives simple & easy.....
I thought this was the best & simplest explanation of these two communication types that anyone would be able to understand...! Excellent job explaining it...!
Good overall view but lacking some of the newer features 1. Bluetooth now requests a passcode to connect (can still use a default preexisting passcode on some devices that don't support passcode entry). 2. WiFi is not only 2.4 GHz, it's also 5 GHz and 6 GHz now. There are also some non standard frequency ranges in use (I've seen 60 GHz listed). Lower the frequency the greater the range, higher the frequency the greater the speed but diminished range. 3. You can also run a network over Bluetooth, although it's slow and you would opt for WiFi instead if you had the choice
The video was made 2 years ago. Of course it will not have the updates that we have today. So I wouldn't use the word "lacking". It wasn't lacking anything at the time of publishing. 6 months from now there will be new updates. Technology is moving fast.
Excellent excellent explanation. Thank you for the graphics. Thank you for the narration and beautiful wording descriptors for each of those wireless connections.
Superb video. Been using both for years, but never really understood the difference. This video made it crystal clear in a way that is understandable to the viewer. Really nice job, and thank you for doing it.
Two points to mention: a) Bluetooth needs a password when pairing the devices; b) the purpose of Wi-Fi is primarily to form a network and then, if necessary, to connect to the internet via a router.
hi, To create a network is a router required? Or are you saying the router is only used as a hub to connect to the internet? Can two phones or other devices make a wifi network without a router with one device acting as a router? thanks
@@sbaxter4207 A wifi device 'can' work in two modes one is connecting to a router the other is direct to other devices no router, not all devices have the option. My HP printer does.
I was active in IT when Bluetooth was developed. The initial idea came from this. A salesman was in a customers office. He had just made a sale, and wanted to give the customer a receipt, but it was impractical to carry a printer around. So Bluetooth allowed the salesman to connect, wirelessly, to a printer in hte customer's office, and produce a paper receipt. One great (unknown today) advantage was that this was in the days before USB ports existed, and there were multiple cable interfaces available, which would have made hooking a laptop or simiar type device to a printer even more difficult .
When an American says "rowter" for this device it grates my ears. I,and many of my fellow Brits (but not all by any means) say "rooter" because most of us say "root" for route, as in path or direction. Great vid, though.
I am definitely glad you made this vid, because alot of people always ask, about the difference between the two. And those animations you use are really nice.
In addition to the Bluetooth USB adapter, there is also a WiFi USB adapter. The WiFi USB adapter is most commonly used for the internet. WiFi USB adapter is good if you do not have an internet router and you have an Android mobile phone and then via WiFi that is via WiFi USB adapter you can share mobile internet on a computer.
Hi, I am back. Where do I start from? There are so many different channels explaining internet things but...Nobody has a better terminology than you, do you have any idea just how great you are? You by far are my favourite channel on youtube. Thank you kindly for your time and effort in making this video. I really hope you realise that your time in making this video hasn't gone unnoticed. "Thank you" so much. 🙌
Thank you! I was wondering for years what it's all about. And no, I'm no beginner but did'nt feel I needed to go to trouble to find out. I used bluetooth to connect expensive ear buds to my smartphone and found out that manufacturers cheated on the public. The cheaper versions would not listen to the navigation app on my smartphone, but to phone calls only. The expensive ones would leave out the first letter of the directions of the app. So I never again purchased any bluetooth device or downloaded an app using it, let aside to buy hardware, for the last approx. 15 years. Still interesting to watching your video!
Cool. Thanks for this simple video explaining both technologies. I knew bits and pieces of both of them, but this video ties it all together. Take care.
I just found your channel😁 (just subscribed) nothing else like this channel on RUclips ! When you consider the content quality. And the ability to explain things so I can absorb it. ..... RUclips's algorithm sucks. because I should have came across your channel a long time ago! And you should have at least 50,000 subscribers. There's so many people that like technology content of this nature.
@@PowerCertAnimatedVideos I've just found your channel today, and it's great to find someone who's willing to explain the technical side of things in clear and simple terms to all of us non-geeks. Subscribed.
Essentially, both Bluetooth and WiFi are used to connect devices to each other (WiFi Direct is also a thing), my concern was why they both exist even though WiFi is seemingly superior. And from what I understood, it's that Bluetooth is more resilient to interference, it has more channels (70 vs 12, so the channels are thinner - more devices can connect to each other in the same space, consume less power and be useful, while fewer devices need a higher broadband, to connect to the internet for example.
The older bluetooth versions 1.0 and 2.0 required a 4 digit passwords especially you devices are of different brands. Except for android to ios pairing which really doesn't work, even on iphone 4 to android. Apple is pretty anal about their "proprietary" tech.
@@billferner6741 if you bluetooth data from iphone to iphone, you must turn on wifi. If there is no internet it won't work. Thank apple's paranoia for that stupid feature. On the other hand, i have never tried to bluetooth from iphone to mac and vice versa.
BT design was fpr stationary devices like AM/FM recievers, amps, tape decks and CD players in consideration. Many non-pro reviewers walk around with their phone in their pocket and cpmplain about drop-outs. Also phone volumes should not be higher than 75 -85% to avoid pops and crackling for BT connections as stated in the phone operating instructions.
This was very helpful. Can you maybe make a video on other communication technology like telephon networks and how they're different from the internet? Thanks for the informative videos man, may God bless you.
There is a password mechanic with the Bluetooth technology but these days they either opt to send the required password as a prompt to the targeted device, use a standard 1234-code mentioned in the manual or neglect the process entirely for the sake of convenience. Though, back in the early days Bluetooth was even less safe. I remember leaving Bluetooth on on my Sony Ericsson T610 and standing at a crowded station when I noticed unsolicited traffic between my phone and an unknown source trying to copy my data.
I’m watching this in the hope of solving a pairing issue between my camera and my phone. You’ve explained lots that I didn’t know about BT but I think my problem is going to require further research/troubleshooting
i always wondered as why industry didn't set a standard for combined use of Bluetooth and Wi-Fi. it is like, the handshake and connectivity authorizations happen over Bluetooth, all control signals go over Bluetooth but the actual data flows over Wi-Fi. as it is, both work from the same chip on a mobile so synchronizing both is not a hard thing to do. so, if I want to send files from my mobile to a friend's mobile, both mobiles could ideally connect and authenticate one another over Bluetooth, and once done and verified, the files would be sent over Wi-Fi which still again uses Bluetooth to ensure that the two mobiles are still close enough, else if they move away, the connection is halted or terminated. this is a security feature which can be implemented easily using Bluetooth.
You can share internet with bluetooth too and even there are some bluetooth Chinese bluetooth routers to connect older devices without wifi to internet wirelessly.
You are The one I was searching for last 2 years … @PowerCert Animated Videos Please make more videos on network connections and network traffic (incoming & outgoing) and also on CPU vs Memory usage and how it is calculated etc.
Very lucid explanation. Many thanks. About Bluetooth you could also have explained how the transmission and reception occurs. How the initial handshake occurs.
I still remember when we transfer Honey Singh's song by Bluetooth We just select 10 songs (because we can't send more than 10 files at once) and leave both phones overnight
There is multi-point bluetooth for one ear piece to many mobile-phones... IF the wifi-antenna were to be used to transmit emulated-bluetooth to broadcast to multiple bluetooth receiver speakers after pairing(within 10 meters)...
Talking about maximum range is very relative. Both BL and Wi-Fi can reach up to dozens of kilometers. You forgot to mention, that Wi-Fi is 802.11 protocol and BL is 802.15.1 protocol. Maximum range depends on the antenna gain and TX power of each radio transmitter. Speaking about interference between BL and Wi-fi. If your device uses the same chain radio transmitter for both BL and Wi-Fi and you have both BL & Wi-Fi turned on and transmit data threw them, then you can measure a significant interference especially on wi-fi , the speed drops probably to 10% which is extremely bad.
Bluetooth is usually one to one, items close to each other for simple tasks. Wifi is about a network where a lot of items are to be connected together, which can be very complicated if choose to.
