Covenant battle network
From Halopedia, the Halo wiki
This article is about the Covenant communications network. For other uses, see Bnet.
The Covenant battle network, often referred to as the Covenant battle net, or simply the battlenet, 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.
Covenant battle network channels are sometimes broadcast on the same frequencies as the UNSC COM, but to date, there is no explanation why; given the fact that this would broadcast the communications of both sides and potentially give up plenty of battle plans for the enemy. The Covenant have been known to broadcast their tactical data through unencrypted battlenet channels. The battlenet can be isolated for deep space broadcast, as well as inter-ship and between units. The battlenet is standard equipment aboard all Covenant vessels, which have both intra- and inter-ship battlenets. It can also be accessed through ground communication equipment such as communication nodes.
The Covenant inter-ship battlenet has a curious feature: a system of communicating orders throughout the Covenant fleet. Transmissions carry embedded sub communiques containing orders for ships to various jumps, rendezvouses and tasks. The efficient system allows orders circulating more quickly throughout the Covenant. However, it seems to have poor counter-intrusion security, as AIs like Cortana seem to have no problem in hacking it.
Through John-117's in-suit communications array, Cortana accessed the Covenant battlenet several times over the Battle of Installation 04 in order to gain intelligence. The battlenet was broadcast over all of Installation 04 and by monitoring it, Cortana was able to discern Covenant activity over the ring. Some of the things she was able to find out provided needed answers about the Covenant activity and the nature of the installation. Cortana also used it to find the crashed UNSC Pillar of Autumn in order to destroy Installation 04. At this point, Cortana mentioned that she was going to search "what's left" of it, indicating that all the chaos threw the battlenet into serious disarray. While raiding the Truth and Reconciliation a second time, Cortana discovered that the battlenet was in such disarray that she couldn't even bring up ship schematics. As a result, she had to rely on records from the last raid to figure out where to go inside the ship.
Near the end of the Human-Covenant War, during the Battle for Earth, a defected Huragok was captured by a squad of ODSTs, and the Huragok agreed to share information in the Covenant battlenet after interrogated by Sergeant Major Avery Junior Johnson. 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.
Jul 'Mdama's Covenant
During the Battle of Requiem in July 2557, Cortana monitored a new battlenet used by Jul 'Mdama's Covenant to learn more about the situation. During the early stages of the battle, Cortana detected reports of Promethean resistance on the battlenet while John-117 fought through Requiem's core.
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. Later, Dr. Catherine Halsey's comm signal was discovered to have bounced off into 'Mdama's battlenet after being traced to "Lockup."
In October 2558, while Blue Team is on Argent Moon, the Jul 'Mdama's battlenet suddenly lights up as a Covenant remnant fleet arrives at the station, causing the team to change their plan to scuttling Argent Moon. As the team makes their way through the station, they pick up chatter on the battlenet about Jul 'Mdama's death in the Battle of Kamchatka.
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.
