The '''proselytization network'''{{Ref/Reuse|Enc22}}, informally termed the '''Covenant battle network''',{{Ref/Novel|TF|Page=38}} or '''Covenant battle net''',{{Ref/Level|Id=halo|CE|Halo (Halo: Combat Evolved level)|Halo}} or simply the '''battlenet''',{{Ref/Novel|FS|Page=55}} is the term for [[Covenant]] communication systems maintained to allow instantaneous contact between units, vessels and planets. It is the equivalent to the [[human]] [[COM]] systems. Following the defeat of the Covenant, various [[Covenant remnants]] have been shown to use the battle net or modifications of it for their own purposes.

==Overview==
[[File:H2_Communications_Module.png|150px|thumb|Covenant communications nodes were used to receive information from the proselytization network.]]
In contrast to its [[UNSC]] [[UNSC battle network|counterpart]], proselytization network was used by the Covenant for domestic, religious and military functions - as opposed to the humans' purely military use cases. The system was designed as a top-down tool for use by the [[San'Shyuum]] and [[Sangheili]] leadership on [[High Charity]] to transmit orders down the chain, but not to receive updates from subordinate nodes. Various methods were used across the network to spread its messages, depending on the importance of the message in question. Central leadership on High Charity could use [[superluminal communications]] links to broadcast orders via [[FLEETCOM (Covenant)|FLEETCOM]] to tithe-worlds and [[Covenant fleet|fleets]] directly, with these imperatives modified by local satraps and commanders spread via the use of less sophisticated [[Covenant comm node|comm nodes]].{{Ref/Book|Id=Enc22|Enc22|Page=217}} All star systems inhabited by the Covenant are fitted with regional [[coordination platform]]s - space stations managed by the [[Ministry of Concert]] to serve a variety of functions involved with the managing of the Covenant's day-to-day affairs with their ancillary functions including serving as nodes in the proselytization network.{{Ref/Book|Enc22|Page=224}} The battlenet is standard equipment aboard all Covenant vessels, which have both intra- and inter-ship battlenets.{{Ref/Novel|FS|Page=63}}

As a consequence of their generally lax computer security and its use in civil and military affairs, the proselytization network was often broadcast entirely on unencrypted channels - something able to be employed against the Covenant via the use of human [[artificial intelligence]] systems. These networks could be accessed by even the communications equipment inside a suit of [[MJOLNIR Powered Assault Armor/Mark V|Mark V MJOLNIR]] armor, with the AI [[Cortana]] able to access and gain information on Covenant force deployments several times throughout the [[Battle of Installation 04|campaign]] on [[installation 04]].{{Ref/Reuse|halo}}{{Ref/Level|CE|The Truth and Reconciliation}} The chaos introduced into the ranks of the [[Fleet of Particular Justice]] by the [[Flood]] outbreak was sufficient to overload the fleet's network, making it near-impossible to access information through it.{{Ref/Level|CE|Two Betrayals}}

Near the end of the Human-Covenant War, during the [[Battle for Earth]], a [[Quick to Adjust|defected Huragok]] was captured by [[Alpha-Nine|a squad of ODSTs]], and the Huragok agreed to share information in the Covenant battlenet after interrogated by [[Sergeant Major]] [[Avery Junior Johnson]].{{Ref/Level|ODST|Coastal Highway}} Two days later, the battlenet fell into disarray again, this time following the [[Prophet of Truth]]'s departure through the [[Portal at Voi]] at the close of the [[Battle of Voi]].<ref name="loot2">''[[Halo Legendary Crate]]'', ''[[Halo Legendary Crate/Data Drops|Data Drop #2]]''</ref>

===Sesa 'Refumee's heretic faction===
[[Sesa 'Refumee]] [[Sesa 'Refumee's heretic faction|heretic faction]] had its own battlenet, but the storm approaching the [[Threshold gas mine]] masked the arrival of [[Thel 'Vadam|the Arbiter's]] team and put the Heretics' battlenet into disarray.{{Ref/Level|H2|The Arbiter}}

===Jul 'Mdama's Covenant===
During the [[Battle of Requiem]] in [[2557#July|July 2557]], Cortana monitored a new battlenet used by [[Jul 'Mdama's Covenant]] to learn more about the situation.{{Ref/Game|H4}} During the early stages of the battle, Cortana detected reports of [[Promethean]] resistance on the battlenet while [[John-117]] fought through [[Core of Requiem|Requiem's core]].{{Ref/Level|H4|Forerunner (level)|Forerunner}}

During the [[Requiem Campaign]] in [[2558]], Jul 'Mdama's Covenant mainly used one of the [[shield world]]'s Forerunner subnets to communicate rather than their battlenet.<ref>''Spartan Ops'', [[Didact's Hand/Hairy Call|S104 ''Hairy Call'']]</ref> Later, Dr. [[Catherine Halsey]]'s comm signal was discovered to have bounced off into 'Mdama's battlenet after being traced to "[[Lockup]]."<ref>''Spartan Ops'', [[Key/The Hammer|S109 ''The Hammer'']]</ref>

In [[2558#October|October 2558]], while [[Blue Team]] was [[Operation: BIRD IN HAND|on]] ''[[Argent Moon]]'', Jul 'Mdama's battlenet suddenly lit up as a [[Jul 'Mdama's Covenant|Covenant remnant]] fleet arrived at the station, causing the team to change their plan to [[self-destruct|scuttling]] ''Argent Moon''. As the team made their way through the station, they picked up chatter on the battlenet about [[Jul 'Mdama]]'s death in the [[Battle of Kamchatka]].{{Ref/Level|H5|[[Blue Team (level)|Blue Team]]}}

===Banished===
The [[Banished]] use a modified version of the Covenant battlenet to connect to different [[FOB]]s and important Banished facilities such as [[Outpost Tremonius (location)|Outpost Tremonius]]. After the Master Chief took control of Outpost Tremonius, he inserted [[the Weapon]] into a terminal where she easily removed the location from the Banished system, securing it.{{Ref/Level|Hi|Outpost Tremonius}} After the Master Chief secured each of the UNSC FOBs in the area, the Weapon removed them from the system as well, securing them. Each time an FOB was secured, the Weapon was able to secure data on Banished operations from the battlenet, including major bases and high-value Banished targets.{{Ref/Game|Hi}}

== Covenant battle network frequencies ==
These frequencies are most commonly used by the Covenant, but it seems that they occasionally utilize the UNSC D- and E- Bands.
