Modern signallers are responsible for the battlefield voice and data
communication and information technology infrastructure or in common English terms, they may carry a backpack radio transceiver used to communicate to forward operating bases (large and small outposts for the military), using a variety of media. All types of wire (line), satellite and
ionospheric radio communication are employed. These include common radio systems such as HF/VHF radio and UHF/SHF radio (operated in line of sight, for example). Cellular radio and telephone systems such as
TETRA are also becoming common.
In addition to day-to-day soldiering, the signaller is required to be competent at a number of skill levels in the following topics:
*Maintaining Power Supplies (Batteries and Charging for example)
*Radio sets; storage and logistics; installation and operation; maintenance and repair at unit level.
*Station Organisation; Managing Radio Nets and Maintaining Net Discipline for example, map marking, log keeping etc.
*Voice and wireless telegraphy procedure (using Morse code or RATT (
Radio assisted Teletype) for example). Formal message procedure, electronic mail.

runners were essentially army messengers and couriers that ran from place to place, culminating in the extensive World War 2, Korea and Vietnam use of the backpack transceiver, eventually becoming unit-based radio and unit-to-HQ based field "telephone".
Specially designated soldiers in a unit would and still do, have a single soldier with a backpack transceiver and large telescoping antennae that can be as tall as 10 meters or 20 feet.
It is also called RTO, which stands for "Radio Telephone Operator". At the field, soldiers usually call them RTO, rather than Signaller. They are soldiers specializing in military communications in the military, mainly operating wired/wireless communication equipment or sending telegrams to commanders from the front line according to the command line, including field headquarters and control agencies.
