SATELITE OVERVIEW
VSAT stands for �Very Small Aperture Terminal� and refers to receive/transmit terminals installed at dispersed sites connecting to a central hub via satellite using small diameter antenna.
VSAT technology represents a cost effective solution for users seeking an independent communications network connecting a large number of geographically dispersed sites. VSAT networks offer value-added satellite-based services capable of supporting the Internet, data, LAN, voice/fax communications, and can provide powerful, dependable private and public network communications solutions.
Generally, these systems operate in the Ku-band frequencies. Ku-band based networks, is used primarily in Europe and North America and utilizes the smaller sizes of VSAT antennas.
TECHNOLOGY
The iDirect iNFINITI series product line includes the 3000, 5000 and 7000 series of remote VSAT routers supporting different levels of user requirements as well as a family of line cards. The iDirect Infiniti series enables network operators to support SCPC, Mesh and Star networks to multiple satellites all from a single hub chassis. The hub solutions built from the iDirect Infiniti series TM platform will allow for scalability to multiple thousands of remote sites. To manage the entire network, operators will be able to use the iDirect scalable Network Management System (NMS) architecture to support global network customers with a single NMS for worldwide implementation.
The iDirect iNFINITI series line of remote routers includes a low cost model optimized for Internet protocol (IP) transfer (iDirect 3000 series), an enterprise class router designed to support business critical applications including VOIP and Video (iDirect 5000 series), and a high end solution offering full encryption and a PCI expansion slot for even greater flexibility (iDirect 7000 series). On the hub router side, iDirect is rolling out a series of interoperable line cards designed to support greater network functionality in a single hub chassis, and virtually unlimited bandwidth when multiple chassis are networked together.
EQUIPMENTS
1) The iDirect Series 3000 Satellite Router
As part of the Infiniti series, the iDirect series 3000 Satellite Router provides an economical entry point into satellite networking and is an ideal solution for small to medium enterprise customers with basic remote networking needs. Able to deliver broadband access of up to 18 Mbps downstream, and 4.2 Mbps upstream, the 3000 series can support all your IP applications remotely, including VOIP and basic Video. iDirect�s series 3000 Remote Satellite Router is a �single box� solution that includes a satellite modem, IP router, TCP acceleration over satellite, and QoS/prioritization in an easy to deploy, reliable design.

2) ANTENNA
Depending on the coverage of your location the antenna size may vary, the normal antenna would be 1.2m, the more the weaker signal the antenna size increases.
3) BLOCK UP COVERTER (BUC):
Earth station transmitter combining signal up-conversion and power amplification in a single unit normally located directly at the antenna input, or close to it.
4) LOW NOISE BLOCK DOWNCONVERTER (LNB)
LNB is a device that processes weak satellite signals directed by an antenna reflector into a feed horn, whilst introducing as little electrical noise as possible in the process.
