VSAT Technology
Logical Wireless offers high quality VSAT satellite solutions to the business, hospitality and private community on the African continent. Our satellite solutions brings connectivity to the remotest of areas, providing Internet , Data, and Voice on Ku & C-band platforms, via state of the art Teleports in the United States and the Netherlands.

VSAT stands for “Very Small Aperture Terminal”, which refers to the technology whereby data is sent and received via an antenna. The antenna size istypically a 1.2m diameter for Ku-Band, or 1.8m diameter for C-Band. The difference between thetwo is the Frequenciy band in which they operate. C-Band systems operate on a lower frequency (3-6 Ghz) and are therefore less affected by rain fade, however due to the size of the hardware they are more costly.

Ku Band systems operate on a higher Frequency (12-14 Ghz), and allow for smaller antennas, but depending on the power of the satellite can be affected by bad weather conditions.

A typical VSAT installation will consist of the following:

• - A satellite antenna capable of transmitting and receiving data.
• - A BUC ( Broadband Up Converter) for transmitting.
• - An LNB ( Low Noise Down Converter) for receiving.
• - Coaxial Cable from the antenna to the indoor modem.
• - A satellite Modem capable of receiving and transmitting data such as E-mails,
•   Internet, VoiP or Video.

• - Connectivity where ADSL or Cable cannot be accessed.
• - Always-on, fast broadband services.
• - Quick deployment.
• - Secure data transmission.
• - Independent of Government operators.
• - Fixed Monthly costs, available in a variety of packages.
• - Private, Professionally managed Teleport.
• - 24/7 Monitoring and support.
• - Worldwide coverage.
• - Single hop, direct access to International Internet Exchanges.
• - Point-to-Point, single hop dedicated satellite connectivity.
• - No Data Caps
• - Redundancy

C- Band
Logical Wireless provides a shared network VSAT solution using the latest DVB-S2 technology developed by ECC (Efficient Channel Coding).

DVB S2 is a new satellite communications standard that provides unprecedented bandwidth and power efficiency and incorporates many advanced features, optimized for satellite communications.

DVB S2 technology developed by ECC, is the first to support optional interactive services (IS) modes defined by the DVB S2 standard. The most important IS feature is (ACM)-

Adaptive Coding and Modulation. ACM enables satellite operators to increase their bandwidth efficiencies by factors of four or more, compared to non ACM enabled systems.

The Satellite Office Solutions (SOS) product is aimed at the small to large business operator, who require a fast, reliable shared solution with low contention ratios and high guaranteed (CIR) bandwidth.
