Answer 2

The spread spectrum approach to wireless communications is employed today in Wi-Fi and some cellular networks to obtain the following benefits:

enhanced reliability - mitigates the impact of wireless interference on a communication channel

increased bandwidth - exploits additional wireless spectrum to better utilize and share bandwidth among multiple channels

improved security - limits the ability of attackers to intercept transmissions

The main idea behind spread spectrum is to separate a wireless communication into a set of related transmissions, send the messages over a wide range of radio frequencies, then collect and re-combine signals on the receiving side.

Several different techniques exist for implementing spread spectrum on wireless networks. Wi-Fi protocols utilize both frequency hopping and direct sequence spread spectrum
