GSM is a mobile communications technology that converts voice conversation into digital data, and transmits this data between phones via cellular transmission towers.
Microwave radiation is generally defined as that electromagnetic radiation having wavelengths between radio waves and infrared radiation. Microwave radiation can be forced to travel in specially designed waveguides. Microwave radiation can be transmitted through space or through the atmosphere in a microwave beam from a microwave antenna and the microwave energy can be collected with a microwave antenna.

Coaxial cable
Coaxial cable, or coax, is an electrical cable with an inner conductor surrounded by a flexible, tubular insulating layer, surrounded by a tubular conducting shield. The term coaxial comes from the inner conductor and the outer shield sharing the same geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who first patented the design in 1880. Coaxial cable is used as a transmission line for radio frequency signals, in applications such as connecting radio transmitters and receivers with their antennas. |
RF connector
A coaxial RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection.
