Which statement describes encryption in wireless networks?

Encryption in wireless networks scrambles data as it travels over the airwaves, making it unreadable to unauthorized parties who might intercept the signal. This directly prevents interception of data in transit, ensuring confidentiality. It does not primarily provide increased protection against spyware, which is typically addressed by antivirus software and secure browsing practices. While encryption can be part of an overall security policy, its direct function isn't to use policies to prevent unauthorized users; that's handled by authentication mechanisms like WPA2/3 passphrases. Converting electrical current to radio waves describes the function of a wireless adapter or access point, not encryption itself.
