FHSS - Frequency Hopping Spread Spectrum

In 802.11 standards, three different modulation/transmission methods are used to transmit wireless signals: 1) Frequency Hopping Spread Spectrum, or FHSS; 2) Direct Sequence Spread Spectrum, or DSSS, and 3) Orthogonal Frequency Division Multiplexing, or OFDM.

These techniques are used for several reasons, including the reduction of natural interference, noise and jamming, and prevention of detection and interception.

In this lesson, I will focus on one of spread spectrum modulation methods used in wireless communications: Frequency-Hopping Spread Spectrum, or FHSS.

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

[oUtLawMaNia]

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

[SG]

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. ♥️

[larryshulman]

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.

I want to give u a huge for doing this, u dont imagine how important for me was to understand this and on what im doing, thank u, thank u, people like u are the real changers, cuz keep the knowledge passing tru generations... U rock man! 🎉

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

[RaviKumar-mfkk]

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

[danielbradley]

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

[silverbell]

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

[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!!

[junwenteh]

Simple and straight to the point, thank you!

Hedy Lamarr sent me here. Amazing invention. 👌

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.

[vighneshnayaks]

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

[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.

[sharvind]

Thank you so much for this very simple explanation.

[JimKQJC]

Very good. Your graphics are excellent. Thank you.
