An InterMesh (IM) is any network of decentralised high bandwidth endpoints communicating autonomously over low latency connections. The term The InterMesh generally describes the largest of these networks, which is available everywhere on Earth. There are estimated to be over a million IM networks of various sizes, the second largest being MarsNet. Various IM networks communicate with others via local or Exonet peering.

As the name suggests, the topology of an IM network is a decentralized mesh of devices and implants acting as transmitters, receivers, and relay points. Most transmissions are via Hyper-OFDM due to its power efficiency, as many IM devices run off power scavenged from the environment or the body housing the implant, but an IM is protocol agnostic and many links use higher bandwidth mediums. The routing protocol is similarly flexible, but in practice is almost exclusively via the Ad-hoc On-Demand Hyperplane Vector (AOHV) protocol due to the highly mobile data paths that are common in most IM networks.

In the BFC 70s the ability to affordably print basic smart dust InterMesh relays from home devices caused a several order of magnitude increase in the connection density in many urban centers. In the subsequent decades the falling cost and increasing capabilities of smart dust made large amounts of computing power available across large swathes of Earth as well as many of the colonies. As a result Infocom Agents start to be able to perform tasks such as run complex simulations, train models to solve issues, and provide AR and other complex entertainment from most locations on Earth.

The InterMesh is the default network for the super-majority of communicating devices, and is the default communication medium for most of humanity. One of its most popular functions is social networking, mostly via neural augmentations, allowing users to share their thoughts, emotions, and experiences directly. Most users have their Infocom Agent set up a DataVeil to control access to their data on these networks. Another widely used feature is health monitoring, allowing internal nanoswarms to sync the latest treatment protocols, although many users disable this due to security and privacy concerns.
