Figure 4 Typical TDM/TDMA network diagram.
 HUBLESS TDMA Network (see Figure 5) consists of equal Earth Stations (Hubless Stations) that
interact with each other through a common TDMA channel (1). This channel is used by all Hubless
Stations to send and receive information with dynamic reallocation of the resource on demand.
Theoretically, all network resources can be concentrated just for transmission or receive of one
particular Network Station, if no other traffic in the network.
One of the Network Stations acts as a Master and takes over the functions of dynamic network
resource allocation between other Stations. To ensure Mesh interactions between all the Stations a
satellite link budget should be designed in such a way that all Stations properly receive each other.
The minimum criterion is that all Network Stations properly receive the bursts of Master Station and
vice versa. However, the network designed under such minimal criteria will behave as Star-topology
system with a center at the Master Station.
High-speed demodulator in Hubless TDMA network is not in use and can be used to receive some
additional traffic via MCPC carrier, such as broadband Internet. It could be a carrier from the same or
from another satellite.
