Which technique is designed to provide communication between two moving units called mobile station. 

  1. Cellular technology

  2. Mobile switching

  3. Paging

  4. Advanced mobile phone system
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cellular technology is designed to provide communication between two moving units called mobile station.

Cellular communication is designed to provide communications between two moving units, or between one mobile unit and one stationary phone or land unit (PSTN). ... Each base station is controlled by a switching office, called a mobile switching center (MSC).

Cellular technology is what mobile phone networks are based on, and it's the technology that gave mobile phones the name “cell phones”. Cellular technology basically refers to having many small interconnected transmitters as opposed to one big one.

A cellular network or mobile network is a communication network where the last link is wireless. The network is distributed over land areas called cells, each served by at least one fixed-location transceiver, but more normally three cell sites or base transceiver stations.

Cellular (cell) phones operate with radio frequencies, a form of electromagnetic energy located on the electromagnetic spectrum between FM radio waves and the waves used in microwave ovens, radar, and satellite stations. Cell phones do not emit ionizing radiation, the type that damages DNA.
