You must plan for encryption in a wireless solution deployment.

Most Vulnerable In Transit: Sensitive data (passwords, health information, etc.) is most susceptible to interception while being sent over a wireless network. Encryption is crucial at this stage.

Encryption at Rest and in Memory: While also important, these are often handled with different cryptographic techniques depending on the system.
