CONT

One of the widely used satellite channel access protocols is demand assigned multiple access (DAMA). This technique matches user demands to available satellite capacity. Satellite channels are grouped together as a bulk asset, and DAMA assigns users variable time slots matching user information transmission requirements. While user notices no change in channel quality, the result is a dramatic increase of up to x4 in communications capacity, number of supported users and networks.
