What is FHSS and DSSS?

Higher signal transmission rate (up to 11 Mbps) FHSS is a robust spread spectrum technique that is suitable to employ in harsh environments. DSSS is a sensitive spread spectrum technique that is influenced by harsh environmental conditions. FHSS is suitable for single point as well as multipoint communications.

What is direct sequence spread spectrum signal?

Direct sequence spread spectrum (DSSS) is a transmission technology used in local area wireless network transmissions. In this technology, a data signal at the sending station is combined with a high data rate bit sequence, which divides user data based on a spreading ratio.

Which is better FHSS or DSSS?

There are a lot of reasons, but let's only discuss one more. FHSS is a much better choice for a one-to-many type of communication while DSSS is better situated for one-to-one communication methods. Otherwise, FHSS is better for FM radio signals while DSSS is better for 802.11 WiFi transmissions.

What is used to define a DSSS channel?

What is used to define a DSSS channel? The center frequency being used by the channel.
