|Information transmitted over a wireless telecommunication network is much easier to intercept as compared to those transmitted over a wired network. This poses major security risks. For instance, the threat of an important file containing a company’s trade secrets transmitted over the wireless network faces the risk of getting intercepted by competitors.
Encryption deals with this issue of transmission security. Information transmitted over a wireless network is often encrypted in a difficult-to-decipher format, so that even when intercepted the information would be meaningless to the perpetrator.
