What Is Wireless Spread Spectrum Communication?
What Is Wireless Spread Spectrum Communication?Answer: 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
