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

==Civilian==
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.<ref>'''Halo: Glasslands''', ''pages 70, 358''</ref> It is known to house civilian network channels such as [[all-news channel]]s.<ref>'''[[Halo: Contact Harvest]]''', ''page 38''</ref> Public COM channels are also known to broadcast cartoons.<ref>'''Halo: Contact Harvest''', ''page 290''</ref> [[COM pad]]s and [[chatter]]s are also linked to public COM networks, and each has its own COM address.<ref>'''Halo: Contact Harvest''', ''page 42''</ref> An "all-COM address" is an official broadcast sent to all communications devices on a given planet. Colonial [[Governor]]s or other high-ranking officials have the authority to broadcast such transmission.<ref>'''Halo: Contact Harvest''', ''page 189''</ref>

==Military==
The term is often used to refer to the name for radio communications systems of [[United Nations Space Command|UNSC]] units. COM allows instantaneous contact between people, ships and [[military base]]s. 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 relay]]s to serve as links to orbiting satellites and relay communications between colonies.<ref>'''Halo: Reach''', campaign level, ''[[Noble Actual]]''</ref>

===UNSC COM channels and systems===
'''[[UNSC battle network|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.<ref>[https://www.halowaypoint.com/en-us/news/community-update-summer-red-summer-blue '''Halo Waypoint''': ''Community Update - Summer Red, Summer Blue'']</ref>

'''E-BAND''': Emergency broadcast channel.<ref>'''[[Halo: Ghosts of Onyx]]''', ''page 159''</ref> 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 [[Terrence Hood|Lord Hood]]'s Reinforcements of their position. Used as an emergency COM Channel.<ref>'''Halo: First Strike''', ''page 156''</ref>

'''FLEETCOM 7''': Short for [[UNSC Fleet Command|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.<ref>'''[[Halo: First Strike]]''', ''page 7''</ref>

'''[[GROUNDNET]]''': A groundside communications network.<ref name="adjunct">'''[[Halo: The Fall of Reach]]''' (2010), ''Adjunct''</ref>

'''HIGHCOM''': Short for "[[UNSC High Command|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.<ref>'''Halo: The Fall of Reach''', ''page 6'' (2001 edition)</ref>

'''[[Secure Network|SECNET]]''': A data network used for secure communications.{{Ref/Reuse|adjunct}}

'''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 [[Heads-up display|HUD]] of other members of their team. Similar to SQUADCOM.<ref>'''Halo: First Strike''', ''page 13''</ref>

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

===Covenant===
The [[Covenant]] and its [[Covenant remnants|splinter factions]] use various communications technologies of their own. The [[Covenant battle network|battle network]], or battlenet, is one known application of Covenant [[Covenant military|military]] communications technology.<ref>'''[[Halo: Combat Evolved]]''', campaign level, ''[[Halo (Halo: Combat Evolved level)|Halo]]''</ref>
