The protocol supports a network of up to a few hundred terminals, depending on the carrier bandwidth and the amount of traffic generated per terminals. However, the protocol can be adapted for use in larger systems, including multi-channel systems.
Data-Link Layer Protocol
The GateHouse Demand Assigned Multiple Access (DAMA) Protocol Stack is a Data-Link Layer (LLC/MAC) protocol for small tactical satellite radio systems supporting data and voice services.
Supporting voice and data
Typical use cases are closed tactical UHF, L-Band, or S-Band radio networks with a limited number of nodes supporting voice and data services such as command/response, chat, or limited file transfer.
Directly from terminal to terminal
A single node serves as the Primary Channel Controller (PCC) and manages the assignment of bandwidth on demand to terminals in the channels. All other terminals act as clients and request access to bandwidth as needed. Data transmissions are directly from terminal to terminal (via satellite), with no need for a separate ground-station downlink carrier, and low latency end-to-end links.
