What is IPoS, and what does it do?
2
Background History

IPoS is the colloquial way of referring to Telecommunications
Industry Association Standard (TIA) -1008[1] which is a
proprietary standard developed and implemented by Hughes
Network Systems.

For any “Technical Contribution” to become a standard there
must be extensive initial engineering committee work and
subsequent TIA community review. [2]

It was approved in November 2003[1]
3
The Basics

IPoS is a system that allows the use of satellites to
extend the possibilities and range of the largest network
of all, the Internet

It uses space-based transponders as an additional link in
wireless communications

It has “always on” or “occasional” use reliability ratings
over 99.8% which is even higher than that estimated for
fiber optic communications [3]
4
The Basics

IPoS works as a kind of mirror in the sky to
relay IP Datagrams sent from one part of the
earth to another.

Think of IPoS as just one more link in the
overall Internet Backbone. It is our cable in the
sky that allows people in diverse locations to be
connected.
5
The Basics

Remember, IPoS is just the mechanism that has
been designed to get IP datagrams from one
location to another when satellites are used to
facilitate wireless communications.

This means that IPoS and IP itself can be
worked on and improved independently of each
other.
6
Why would anyone want IPoS?

It eliminates geographical barriers that limit traditional
methods of IP datagram transmission such as through
ground based cable and wireless systems.

No need to invest in “expensive terrestrial networks.”
Plus, it is very efficient and allows successful,
simultaneous transmission with other services such as
television. [6]

(paraphrased) [6]

Services?

IPoS allows “single-hop” transmission [6] of
voice, data, and video that have been
encapsulated in IP datagrams

IPoS systems also allow simultaneous
transmission of digital television [6] using
additional transponder capacity. Also radio,
telephone, and non-IP communications services
can be bundled with IPoS

Summary

IPoS (TIA-1008) was developed by Hughes Network
Systems

It is widely recognized within the telecommunications
community as the medium for transmission of IP
Datagrams

Think of IP and IPoS as two interconnecting highways.
Where one starts another ends and vice-versa
