Multipoint-to-Point (Interactive) Connectivity
The Multipoint-to-Point network provides two-way interactive communications between a central hub earth station and multiple remote user terminals.
This connectivity is used for because it reduces the technical requirements of the remote locations.
Each remote VSAT must have the ability to transmit data back to the same satellite as the hub uses to broadcast out.
In a Multipoint-to-Point network, transmission data rates are asymmetrical, meaning that the hub transmits at a much higher data rate than each remote VSAT.
Multipoint to point connectivity, combining an outbound broadcast with multiple inbound transmissions from remote terminals.
Solid lines represent the broadcast from the hub.
Dotted lines indicate multiple access transmissions from the VSATs.
