What does a VPN Use to Ensure that any Transmissions that are Intercepted will be Indecipherable?

What does a VPN use to ensure that any transmission that are intercepted will be indecipherable?

The tunnel (logical path) con- tains private data that has been encapsulated, and the VPN contains private data that has been encrypted. The encapsulated data (or packets) are encrypted for confidenti- ality, so if any packets are intercepted on the public network, they are indecipherable without encryption keys.

What is Bluetooth's rate of transmission?

Bluetooth operates in the same 2.4- to 2.483-GHz unlicensed spectrum as Wi-Fi. It uses a technique known as frequency-hopping spread spectrum (FHSS), where the data is divided into chunks and transmitted via a carrier that hops from one random frequency to another. Data is transmitted at a 1-Mbps rate using FSK.
