"The Covenant Battle Network is in disarray!"

- Cortana to the Master Chief.

The Covenant Battle Network, or 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 system.

Covenant Battle Network channels are sometimes broadcast on the same frequencies as the COM, but to date, there is no explanation why; given the fact that this would hamper the communications of both sides and potentially give away battle plans. The Battle Net can be isolated for deep space broadcast, as well as inter-ship and between units. It should also be noted that the Battle Net was broadcast over all of Installation 04 and by monitoring it, Cortana was able to discern Covenant activity over the ring. Battle Network channels are also unencrypted usually, likely because the Covenant do not believe humans pose a threat either way and think that their extinction is imminent and unavoidable.

The Battle Net is standard equipment aboard all Covenant vessels, but ground communication is best made using Uplink Crates.

The Covenant inter-ship Battle Net has a curious feature: a system of communicating orders throughout the Covenant Empire. Transmissions carry embedded sub communiques containing orders for ships to various jumps, rendezvous and tasks. The efficient system allows Covenant orders to circulate more quickly throughout the Empire.

However, it seems to have poor counter-intrusion security as AIs like Cortana seem to have no problem in hacking it.

The first time that the Battlenet was mentioned is on the level Halo of Halo: Combat Evolved.
