Satellite CommunicationSatellite is a microwave device
consisting of receiver, repeater and regenerator in orbitSatellite
transmission involves sending signals to satellite that receive,
amplify, and transmit back to earth

Satellite Communication is Best SuitedFor signals originating
from a single site with simultaneous distribution to many remote
sitesFor remote sites which are located in geographically dispersed
areasFor delivery of large volumes of data to remote sites with
relatively small volume return channel
Multimedia Applications
Applications such as text, image, video and real time signals
served on a common transmission media are known as Multimedia
Applications.
Multimedia Applications (Contd)Significant Amount of Bandwidth
is required. Broadband Infrastructure is required.
What Is Broadband VSAT Network?It is a VSAT network designed to
receive and transmit wideband signalsA VSAT network that supports
multimedia application.
What Is Broadband VSAT Network? (Contd) A Broadband VSAT Network
is a flexible platform allowing multimedia services such as digital
video, WAN, Internet, video-conferencing and rural telephony on a
single infrastructure.
Benefits of Broadband VSAT NetworkSame resource can be shared by
a group of users.Efficient Utilization of Resources.Multiple remote
sites can get access to information concentrated in capital
cities.High network availabilityFast deployment
