COM

From Halopedia, the Halo wiki

(Redirected from SATCOM)

Shorthand for "Communications", COM is a term used to describe networks and radio communications systems of varying kind.

Civilian[edit]

In civilian context, COM refers to communications channels such as Public COM, which appears to be similar to modern-day television or Internet and may be connected to Waypoint due to the systems' similar nature.[1] It is known to house civilian network channels such as all-news channels.[2] Public COM channels are also known to broadcast cartoons.[3] COM pads and chatters are also linked to public COM networks, and each has its own COM address.[4] An "all-COM address" is an official broadcast sent to all communications devices on a given planet. Colonial Governors or other high-ranking officials have the authority to broadcast such transmission.[5]

Military[edit]

The term is often used to refer to the name for radio communications systems of UNSC units. COM allows instantaneous contact between people, ships and military bases. There are any number of COM frequencies or networks for any number of tasks. COM systems are standard equipment in all armor systems, as well as vehicles and ships. Many human colonies have networks of communications relays to serve as links to orbiting satellites and relay communications between colonies.[6]

UNSC COM channels and systems[edit]

Battlenet: Short for the distributed battle management and communication network. It is the major UNSC military communications network used for battlefield management and tactical support.[7]

E-BAND: Emergency broadcast channel.[8] Little-used public frequency. After the fall of Reach, Anton-044 used the E-Band to transmit a signal of Oly Oly Oxen Free. It was also used by the UNSC forces on Onyx to notify Lord Hood's Reinforcements of their position. Used as an emergency COM Channel.[9]

FLEETCOM 7: Short for Fleet Command. Public frequencies were used around the planet Reach. Broadcasts on FLEETCOM 7 would reach any UNSC navy ship in range of the sender.[10]

GROUNDNET: A groundside communications network.[11]

HIGHCOM: Short for "High Command", this band is used by and to contact the ranking officers in UNSC High Command.

SATCOM: Short for Satellite Communication. Frequencies reserved for communications with orbiting satellites, sometimes to relay information to orbiting ships, sometimes for communicating with people or units in another section of the planet. COMsat stations must be in orbit in order for SATCOM to be usable.[12]

SECNET: A data network used for secure communications.[11]

SQUADCOM: Frequencies reserved for use among small units in a specific area. Squadcom has a very small range, it is usually intended to be broadcast over short distances. Usually, radio-communications that take place in Halo: Combat Evolved occur over a SQUADCOM.

TACCOM: Short for Tactical Communication. Frequencies reserved for sharing of information between small units on the battlefield. While audio communication is not possible on TACCOM, one team member can upload images, NAV points, and sensor information into the HUD of other members of their team. Similar to SQUADCOM.[13]

TEAMCOM: Private communications channel for a small number of military and covenant units, usually a Fireteam.

Covenant[edit]

The Covenant and its splinter factions use various communications technologies of their own. The battle network, or battlenet, is one known application of Covenant military communications technology.[14]
