	Private Mobile Radio (PMR) Jargon
		PMR is the oldest form of mobile communications – it has been in use for over 70 years.
		PMR is particularly well suited to operations requiring the passing of frequent short voice or data messages from a central point to individuals or groups of personnel.
		The receiving radio is tuned to the same radio frequency as the transmitter, but will only "unmute" its speaker, allowing the message to be heard, if it can detect that the appropriate tone is present.

		Mobile phones allow connections to be made to the telephone network, normally by directly dialling the other party's number on an inbuilt keypad.
		Most current mobile phones use a combination of radio wave transmission and conventional telephone circuit switching, though packet switching is already in use for some parts of the mobile phone network, especially for services such as push to talk.
		Mobile phones began to proliferate through the 1980s with the introduction of "cellular" phones based on cellular networks with multiple base stations located relatively close to each other, and protocols for the automated "hand-off" between two cells when a phone moved from one cell to the other.

	Professional Mobile Radio - Wikipedia, the free encyclopedia
		A trunked version of the Private Mobile Radio (PMR) concept that is defined under the standard MPT 1327 (MPT1327) is widely used and provides significant advantages over the simpler single station systems that are in use.
		One of the problems encountered by mobile signalling systems is that of clashes when two or more mobile radio units try to transmit at the same time on the control channel.
		The mobile radio unit will randomly select a slot in which to transmit its request but if a message is already in progress then it will send its access message in the next available slot.

	Mobile phone - Wikipedia, the free encyclopedia
		Mobile phones are also distinct from cordless telephones, which generally operate only within a limited range of a specific base station.
		Mobile phone use on aircraft is also prohibited, because of concerns of possible interference with aircraft radio communications [4].
		Professional mobile radio systems are very similar to cell phone systems and attempts have even been made to use TETRA, the international digital PMR standard, to implement public mobile networks, but normally PMR systems are sufficiently separate from the phone network to not really be considered phones but rather radios.

	Mobile phone - Facts, Information, and Encyclopedia Reference article
		A mobile phone, also known as a cellphone, mobile, or handphone, is an electronic telecommunications device with the same basic capability as a conventional fixed line telephone, but which is also entirely portable and is not required to be connected with a wire to the telephone network.
		The mobile phone communicates via a network of base stations which are in turn linked to the conventional telephone network.
