Figure 3 - Terralite Internal Network Schematic	Ground IP Satellites - "Terralites" consist of a group of Primary Cell Controllers (PCC’s) connected via Ethernet to a Satellite Link Controller (SLC). Each PCC provides service to a geographic area and the set covers all of the customer service area of the Satellite. A Satellite may cover a full circle or some segments depending on need and can be quickly modified as needed. Satellite Link Controller (SLC) Trunk Band operation used for bulk traffic between Satellites acts as router Balances traffic load to nearby Satellites manages inter-satellite encryption
Primary Cells Primary Cells illuminate a geographic area and provide access to the Nobell Transport Network to Customer Premises Equipment in that area. The antenna, power levels, and terrain determine cell coverage area. Within a satellite, they are connected with each other and a Satellite Link Controller.

Terralites communicate with each other using Satellite Link Controllers which are essentially IP routers with RF links. Each Satellite can communicate with other Satellites within its range to balance the load as traffic warrants.
