Summary
DVB based Outbound – 2.5 to 52.5 Mbps
Inbound bit rate – 38.4 to 307.2 Kbps – R.S.
Coding
Stand alone remote unit with routing
capabilities
Large networks using shared HUB are cost
effective for delivering Internet service to
remote areas
Possibility of bundled service of telephony
and Internet on the same platform
It contributes to bridge the digital divide
immediately
