As per my knowledge, AT Command and TNP1 protocols are used in TETRA
protocols used for network device.
Communication rules are called protocols.
The full name of GSM is "Global System for Mobile Communications." It is a standard developed to describe protocols for second-generation (2G) digital cellular networks used by mobile phones. Originally developed in Europe, GSM is now widely used around the world for mobile communication.
A TETRA mast is a structure used to support antennas for TETRA (Terrestrial Trunked Radio) communication systems, which are widely utilized in emergency services and public safety networks. These masts facilitate reliable, secure, and efficient communication for users such as police, fire, and medical services. TETRA masts are designed to provide extensive coverage and can be equipped with multiple antennas to handle various frequencies and communication needs.

difficult to say
micro wave is used in cell phone communication.
They are; mobile phones are no more dangerous than a radio station.
AMPS
mobile means portable, phone is used to communicate. so the mobile phone is giving us the meaning that the communication device which is can be portable.
the frequency used in mobile communication should be greater then 30mhz so cannot be reflected by the ionosphere thats why we are using a frequency of range less ghz so called "radio waves"
The ZigBee module is a collection of high level protocols used for communication that can be used to create personal area networks from digital radios.
