Frequency Hopping Spread Spectrum (FHSS) FHSS uses a narrow frequency band and 'hops' data signals in a predictable sequence from frequency to frequency over a wide band of frequencies. Because FHSS shifts automatically between frequencies, it can avoid inte...

Direct-Sequence Spread Spectrum (DSSS) The transmitter breaks data into pieces and sends the pieces across multiple frequencies in a defined range. DSSS is more susceptible to interference and less secure then FHSS.

About wireless networking notes
GoConqr OriginalWhat the wireless networking notes cover
The notes offer short readings on different parts of the unit. Media Access describes collision avoidance, while Ad hoc and Infrastructure look at ways wireless devices connect. Devices introduces wireless network interfaces and access points.
For a different focus, the notes on frequency hopping and direct-sequence spread spectrum describe how each method sends signals across frequencies. The note on sensor network optimisation brings together coverage, connectivity, energy and sensing range.
Make the notes work for you
Start with Devices if you want to review the equipment, then read Ad hoc and Infrastructure alongside it. Write a short comparison in your own words before moving to Media Access.
When you want to check what you remember, switch to a quiz on the unit page. If you would rather see connections between topics, try a mind map. Choose a note and make a brief summary as you read.
Frequently asked questions
Which note is a useful starting point?
Start with Devices if you want to review the equipment used in a wireless network. Then read Ad hoc and Infrastructure to compare direct connections with networks that use an access point. Media Access is a useful next note when you are ready to look at collision avoidance.
Do I need an account to use these notes?
No. Every note listed on this page is free to open and study without an account. The resources were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
What can I read about spread spectrum?
The page lists Frequency Hopping Spread Spectrum (FHSS) and Direct-Sequence Spread Spectrum (DSSS). The notes describe different ways of sending signals across frequencies. Read them together to compare their approaches, then use a quiz on the unit page when you want to check your understanding.
