UHP HUBLESS Full Mesh Network

UHP Hubless TDMA is a versatile VSAT network, operating without a central Hub. It can support any network topology (star or mesh) and is a good fit for many applications. Every Hubless TDMA station has similar architecture and may communicate with the others over a single-hop satellite link, while one station is designated as master and is responsible for maintaining the timing and allocating bandwidth.
The smallest size Hubless TDMA network consists of only two stations which communicate via a common TDMA carrier. This network can be expanded up to 2 000 sites operating via up to 8 MF-TDMA carriers shared by all stations simultaneously. Such network development does not require any hardware replacement of the existing sites. Affordability of the equipment combined with highly-efficient utilization of satellite capacity ensures the best total cost of network ownership. Hubless TDMA is also a good choice rational solution for replacement of obsolete SCPC channels; this can significantly boost the total traffic in the system, due to statistical multiplexing of user traffic with sophisticated QoS policies.
Owing to software-definable architecture of the UHP platform, Hubless TDMA technology can be a good entry solution for a private
VSAT network, eliminating the need for expensive central
infrastructure at an early stage of network rollout. At any time Hubless TDMA network can be remotely switched to TDM/TDMA mode without replacing any hardware or even visiting the sites.
