Tachyon

Safe, secure collocation and aggregation facilities for your equipment, so you can deliver services to your customers right to the last mile. It acts as an aggregation point for your access network.

Tachyon nodes are at strategic locations in our network, covering all major metros and small towns where we have network footprint. This means you can build your own core network by positioning your equipment close to your customers’ sites and efficiently backhauling traffic between the last-mile and your core network.

Architecture

Tachyon lets you host your network equipment wherever your customers are.  It is a cost-effective way to aggregate traffic in a geographical area.
