VSAT NETWORK

UHP broadband VSAT networks provide a variety of modern telecommunications services to different customer groups - small and large businesses, governmental and individual users. Satellite network ensures global coverage and its services are available virtually everywhere.It is the fastest and most efficient way to connect a number of remote users into a single global network with service quality comparable or exceeding performance of terrestrial infrastructure in large cities.UHP network uses efficient TDM/TDMA bandwidth on-demand multiple access to a satellite capacity. The typical UHP network consists of one Hub and number of associ-ated remote terminals. UHP terminals may operate in hub-and-spoke (star) topology or in mesh mode, when terminals are connected via a single satellite hop bypassing the Hub. UHP terminals require no local management and are fully managed by the Hub.

UHP TDM/TDMA HUB

The Hub consists of one or more UHP-1000 satellite routers. In its basic configuration, it has a single UHP-1000 router which transmits one outbound TDM carrier towards all the remote ter-minals and receives one inbound TDMA carrier shared between all the remotes. Additional satellite routers are required in order to support more inbound carriers and/or to create 1:1 redundant configuration in the Hub. TDM/TDMA Mesh feature allows single-hop connectivity between the remotes via the TDMA carrier also used in the inbound.    The Hub is typically installed in one or more 19” rack mounted chassis.

 The outbound TDM channel makes use of the most efficient modulation and coding technologies based on DVB-S2 (or DVB-S) industry standard. The design of the outbound channel, in com-bination with an innovative, bandwidth-saving TDMA protocol and LDPC FEC coding in the inbound channel, ensures industry-lowest operating costs and delivery of highest-quality services. UHP technology has unparalleled versatility and minimizes both CAPEX and OPEX, thus guaranteeing the lowest total cost of ownership for satellite network of any configuration.
