It operates in 5 GHz band, and uses a 52-subcarrier orthogonal frequency-division multiplexing (OFDM) with a maximum raw data rate of 54 Mbit/s, which yields realistic net achievable throughput in the mid-20 Mbit/s. The data rate is reduced to 48, 36, 24, 18, 12, 9 then 6 Mbit/s if required.
Bluetooth uses short wavelength radio transmissions in the ISM band from 2400-2480 MHz
802.11a uses a 5.0 frequency and supports 54 Mbps, and doesn't encounter interference from cordless phone, microwave ovens, and bluetooth devices.
It uses radio waves. The frequency band is the same as some cordless telephones.
Radar uses radio waves.
The XM Radio satellites use S-band frequencies from 2,332.50 through 2,345.00 MHz, and Sirius Radio uses adjacent frequencies 2,320.00 through 2,332.50 MHz.
XM is a satellite radio and comes to you via satellite. AM doesn't need to use satellite to broadcast it uses a radio band. If AM needed satellite we wouldn't have had it since the 1920's.
The Citizens Band radio is defined to be a short distance radio communications device. Its uses includes cheap and efficient talking between two stations without any interruptions.

Radar is an object-detection system that uses radio waves to determine the range, altitude, direction, or speed of objects
Radar stands for "Radio Detection and Ranging." It is a system that uses radio waves to detect the presence, direction, distance, and speed of objects such as aircraft, ships, and precipitation in the atmosphere.
