SkyWAN
®
uses an MF-TDMA system supporting a variety of satellite network topologies (fully-
meshed, hybrid, star). Main network features are:
- Wide hopping range (from burst to burst) over 800 MHz (transponder hopping)
- Data rates from 64 kbit/s up to 10 Mbit/s per channel, up to 8 channels are supported
- Highly dynamic assignment of transmission capacity
- Integration of real-time and non-real-time applications into a packet switching architecture
- Frame Relay switching, including Quality of Service (QoS) support
- IP routing, including QoS support
- Acceleration of transmission control protocol connections (TCP-A)
- Support of many applications like
- Traditional telephony systems (ISDN, analogue)
- Voice and Video over IP (V2oIP) with efficient header compression
- LAN interconnection via Frame Relay and/or IP
- GSM backhaul solutions
- SNMP based network management system
- L-Band transmit- and receive interface between indoor unit (IDU) and outdoor unit (ODU).
SkyWAN
®
Technology offers the following advantages over competing satellite communication
technologies:
- Flexibility: By allowing meshed, star and hybrid topologies, SkyWAN
®
networks can be
ideally adapted to diverse customer requirements.
- Versatility: By supporting IP based and legacy network protocols any type of business
communication may be supported.
- Scalability: From small networks consisting of few stations to large ones with hundreds of
stations SkyWAN
®
networks can be tailored cost efficiently to customer demands.
- Availability: The built-in Master/Backupmaster functionality with automatic switchover es-
tablishes a network without single point of failure.
- Performance: Symbol rates ranging from 100 to 6000 ksps per carrier allow support of
high bandwidth applications.
- Efficiency: By defining a common bandwidth pool for station groups, overall network band-
width consumption is reduced by statistical multiplexing.
