Wireless data communication

According to my understanding if data has to travel through wires and beyod a point it has to travel in a wireless environment, the data is decrypted at the access point and will again be encrypted here depending on what encryption technology the access point is using. Is it correct? Please correct me if I am wrong. Thanks

Thanks. We'll let you know when a new response is added.

Wireless access points don’t always encrypt data specifically.

If the access point is configured without encryption then the connection will not be encrypted.

If the access point is configured for encryption then as the data flows from the wired network through the access point the data will be encrypted over the air. The access point at the other end (or computer with a wifi card) will then decrypt the data and send the unencrypted data over the hard wire network.

Data can be transmitted over the hard wire network as well using IPSec.

    It depends on your encryption settings in your AP but wireless data running over WEP or WPA is encrypted between your computer(s) and the AP or other computers. Beyond that (i.e. out to the Internet) it's no longer protected unless you're using SSL/HTTPS, a VPN, etc.
