FHSS - Frequency Hopping Spread Spectrum

[@sadunkumara3699]

My lecturer took two hours to explain this simple thing. Thank you. May u live long

[@pattty847]

why can't youtube offer degrees?

[@oUtLawMaNia]

The most underrated lecturer on the internet! You put things into perspectives that are so easy to grasp, thank you very much!

[@20SG20]

Plain, simple, and to point. I respect you, Professor Sunny. ❤️‍🔥.

[@talismanicac]

The simplest and easy to understand concept of DSSS & FHSS by you on youtube. ♥️

[@larryshulman8845]

excellent video series, probably one of the best I have ever seen , clear, imaging based, understandable for an old engineer like me that responds to visuals first and math 2nd.

[@gabodiaz984]

Please Teacher Sunny !!!! Dont stop to make videos . These are really easy and interesting to get them

[@sunnyclassroom24]

Thank you for supporting !

[@Icefy_2024]

I Love It When The Notification Comes, "Someone Has Subscribed Your Channel" 😁 It Always Makes My Day!

[@danielbradley753]

This is great, your voice is very clear and concise through the video and the explanation seems obvious 🎉 Just why I need

[@sunnyclassroom24]

Great to hear!

[@mariodelzo]

Thank you so much, I was reading a whole book for many hours, but with this video I just take 5 minutes to ilustrate the ideas very clear and summarize. Hope find more videos of other topics with this didactic , well done!!

[@sunnyclassroom24]

Wonderful!

[@silverbell6160]

I love your explanations, they are so clear and simple. Great!

[@RaviKumar-mf8kk]

Thank you very much for the simplification in such a short and nice video.

You re welcome !

Hedy Lamarr sent me here. Amazing invention. 👌

[@sunnyclassroom24]

Thank you for watching!

You put the whole sea in a single glass. That’s magnificent

Whats nice about non-native english speakers is that they speak simple to understand sentences and don't use informal speech. And that actually makes it easier for non-native speakers to understand.

[@aaaaa2332]

Hello sunny it was a really nice lecture. Short and sweet. Please make a video on ofdm

[@sunnyclassroom24]

I will. It is on my to-do-list. I will upload it soon, hopefully.

[@aaaaa2332]

@@sunnyclassroom24 thanks for your quick response.

[@sunnyclassroom24]

No problem. I normally answer within 24 hours unless I travel or business trip.

[@sunnyclassroom24]

OFDM - Orthogonal Frequency Division Multiplexing I do not know if you watched it on my channel.

[@junwenteh]

Simple and straight to the point, thank you!

[@TheSkyLegend]

Just a simple correction here. The time that you mentioned as the Hop time is the Dwell time. The Hop time is the amount of time needed to move from one frequency to another, which does not exist in your graph.

[@vighneshnayaks7379]

Thanks a lot, got to know FHSS at superficial level, and did better job than my lecturer.

[@aneupan]

Very well explained. I liked that you videos are short, but at the same time very detailed. You've earned a subscriber. And, please make the future videos shorter too. Thank you.

[@sunnyclassroom24]

Thank you ! you made my day!

[@NaqeebAl]

Thank you Sunny, some of the best explanations on KZbin. It's clear that you spend time and care in making the animations for these videos and it's nice to see the tens of thousands of people who benefit from them.

[@sunnyclassroom24]

Wow, thanks! That is my passion to do .

[@JimK0QJC]

Very good. Your graphics are excellent. Thank you.

[@RagibShahariar]

I wish you had released these videos in my undergrad -_- God bless.

[@brunatogomes1627]

the best expanations i have ever seen

[@sharvind8852]

Thank you so much for this very simple explanation.

[@Anonymous-ed4id]

This is so beautifully explained!

[@antoniopintus8568]

Just great! thank you very much for sharing those classes! top!!!

[@sunnyclassroom24]

My pleasure!

[@tuxuday]

How a packet once sent by the sender, can hop to different frequency before reaching the receiver? Changing frequency requires energy! So i reckon once a packet is sent it will be in the same frequency. Maybe the next packet will be in different frequency.

[@mortenlund1418]

He means the packet is divided and send partly on the different channels.

[@juanwallace3053]

@@mortenlund1418 Thank you!

[@romansteinebrunner5735]

A packet is always sent on one frequency, but the next packet will be on another Channel. As you Said, the frequency of an Already sent packet Canon be changed

[@NerdyDumbProductions]

Thank you again Sunny, love your lectures :)

[@rayantoufaily6061]

incredible, I learnt so many things

[@MrNandu32]

Great information about the FH.

[@Onvervain__]

Very easily explained 🔥

[@javierlujan9249]

Thank you for your easy explanation, this is really helping me a lot, thank you sir

[@sunnyclassroom24]

You are very welcome!

[@nilshrestha9147]

i think the data packet doesnot jump to another frequency in the middle of transmission,instead i think the user data packets are send in a certain sequence using the various small channels ,and through which channel it will go is already decided before sending

[@stevenshakes978]

Thank you Sunny!

[@dennisasamoah2213]

Btw, nice and short lecture to explain the concept..... good job

[@sunnyclassroom24]

It's my pleasure

[@electronicprojecttutorial]

Very clear explanation!

[@Toto-cm5ux]

Very interesting but how does the receiver know the hopping-pattern in FHSS WiFi technology ?

[@rvscootin3457]

Excellent example - Thanks!

Good video, great teching skills!

[@rasswanth4968]

Good Lecture Sir.

[@maxheadrom3088]

One question: the packages change frequencies or the sender and receiver change the frequency used for each package? I mean, a package sent in F2 will always travel in F2 but the next package will be sent through F5 and so on. Thanks!

[@mortenlund1418]

I see this is a security benefit, but is it also benefitting regarding interferrence? That I dont see?

[@sunnyclassroom24]

because there is a pattern in hopping, and noise or other interference do not have a pattern. When the receiver gets the signals, they can retrieve original signals and get rid of noises.

[@Constitution1789]

So it's relatively secure? Better or the same as DECT 6.0?

[@needsomehike]

is it used today in our wireless 2.4-5 GHz wireless networks?

[@ANALOGTecHII]

What is the time of hopping in GSM voice signal

[@violinvvv]

Very clear, thank you

[@KellenSantana-s7r]

Excellent ❤

[@anandprakash9457]

Sunny Sir, what if the eavesdropper is listening on all the 79 channels ?

[@cenkcaba5757]

thank you so much. very nice

[@jakubadamczewski3477]

Another amazing video, thank You!

[@tanmoydutta5846]

But I have one question: How can data transmission signal change its frequency abruptly "during transmission"???? Isn't frequency change done from devices?

[@fraserbc]

There's a mistake in this video. What he is calling hop time is actually dwell time and the time inbetween transmissions is hop time which isn't shown on this graph

[@Cyberfako]

I would like to ask how reciever know the changed frequency ? Reciever listen depends on what in this protocol ?

[@augmentos]

Are there any military jammers that can block FHSS without blocking all frequencies?

[@fraserbc]

If you can predict what the next channel is then yes but the crytographic algorithms and keys which determine that are closely guarded secrets

[@augmentos]

@@fraserbc so you are saying essentially FHSS would be impervious to gov scanners on an unpredictable Algo?

[@rohullahhussaini3351]

thanks Sunny, you're awesome

[@sunnyclassroom24]

Thanks a lot.

[@hafissafwan]

Good explanation better use 1.25 speed while watching

[@sunnyclassroom24]

Thank you for supporting!

[@sheharanshrestha9382]

Why was the 2.4GHz frequency band divided into 79 narrow frequency channels? Why not 83.5 narrow frequency channels since the difference between 2.4Ghz and 2.4835GHz is 83.5MHz where each channel was considered to be 1MHz wide.

[@mayurgare]

Nice Explanation THANK YOU

[@bhuvaraga]

Question: How does the receiver know what pattern is used for this transmission? Is it first sent and agreed before transmission?

[@jeffreydijkstra3391]

Both receiver and sender have a predifined hopping sequence not knows by other devices

[@rsstnnr76]

How does it jump though?

[@ismailhamzaansari179]

To avoid interference and to provide more security

Sir what if two different signals land on the same channel at the same time. For example, signal S1 and another one S2 use the same channel F2 at the same time T3.
