A radio transmission technology that spreads the user information over a much wider bandwidth than otherwise required in order to gain benefits such as improved interference tolerance and unlicensed operation.
The ability to transmit data or information over a wide range of frequencies, and then reassemble the message when it is received.
Technique to reduce and avoid interference by taking advantage of statistical means to send a signal between two points. A figure of merit for spread spectrum systems is "spreading gain" measured in DB. The two types of commercial spread spectrum techniques are frequency hopping and direct sequence.
