communication through VSAT
(i) Optical fiber provides a wider bandwidth and so greater data rate flow through over conventional copper cables.
The worldwide internet mainly depends on the optical fiber link
SEA-ME-WE for its operation, which covers europe , middle asia and western asia. Optical fibers provides data rate upto 100 Gbps.
(ii) VSAT networks are basically satallite communication, it stands for 'very small aperture terminal' and are provided with dish antennas with very small dimensions of about 1m.
This communication is done in ku band and 'ka' band, which are also called microwaves.
1. Free Space Optical communication
2. Adaptive signal processing
3. Ultra Wideband Networks
4. Multitouch Sensing
6. Human Area Networks
and now it comes to topics concerned to seminar you can go for field like ,microprocessors,vlsi,emmbeded system,they are worth to disscus.
