Background HistoryBackground History IPoS is the colloquial way of referring to IPoS is the colloquial way of referring to

Telecommunications Industry Association Telecommunications Industry Association Standard (TIA) -1008[1] which is a proprietary Standard (TIA) -1008[1] which is a proprietary standard developed and implemented by Hughes standard developed and implemented by Hughes Network Systems. Network Systems.

For any “Technical Contribution” to become a For any “Technical Contribution” to become a standard there must be extensive initial standard there must be extensive initial engineering committee work and subsequent TIA engineering committee work and subsequent TIA community review.

It was approved in November 2003[1] It was approved in November 2003[1]

The BasicsThe Basics

IPoS is a system that allows the use of IPoS is a system that allows the use of satellites to extend the possibilities and range satellites to extend the possibilities and range of the largest network of all, the Internetof the largest network of all, the Internet

It uses space-based transponders as an It uses space-based transponders as an additional link in wireless communicationsadditional link in wireless communications

It has “always on” or “occasional” use It has “always on” or “occasional” use reliability ratings over 99.8% which is even reliability ratings over 99.8% which is even higher than that estimated for fiber optic higher than that estimated for fiber optic communications [3] communications [3]

The BasicsThe Basics

IPoS works as a kind of mirror in the IPoS works as a kind of mirror in the sky to relay IP Datagrams sent from sky to relay IP Datagrams sent from one part of the earth to another. one part of the earth to another.

Think of IPoS as just one more link in Think of IPoS as just one more link in the overall Internet Backbone. It is the overall Internet Backbone. It is our cable in the sky that allows people our cable in the sky that allows people in diverse locations to be connected. in diverse locations to be connected.

The BasicsThe Basics

Remember, IPoS is just the mechanism Remember, IPoS is just the mechanism that has been designed to get IP that has been designed to get IP datagrams from one location to another datagrams from one location to another when satellites are used to facilitate when satellites are used to facilitate wireless communications. wireless communications.

This means that IPoS and IP itself can This means that IPoS and IP itself can be worked on and improved be worked on and improved independently of each other. independently of each other.

Why would anyone want Why would anyone want IPoS?IPoS?

It eliminates geographical barriers that It eliminates geographical barriers that limit traditional methods of IP datagram limit traditional methods of IP datagram transmission such as through ground based transmission such as through ground based cable and wireless systems. cable and wireless systems.

No need to invest in “expensive terrestrial No need to invest in “expensive terrestrial networks.” Plus, it is very efficient and networks.” Plus, it is very efficient and allows successful, simultaneous allows successful, simultaneous transmission with other services such as transmission with other services such as television.

Services?Services?

IPoS allows “single-hop” transmission IPoS allows “single-hop” transmission [6] of voice, data, and video that have [6] of voice, data, and video that have been encapsulated in IP datagramsbeen encapsulated in IP datagrams

IPoS systems also allow simultaneous IPoS systems also allow simultaneous transmission of digital television [6] transmission of digital television [6] using additional transponder capacity. using additional transponder capacity. Also radio, telephone, and non-IP Also radio, telephone, and non-IP communications services can be communications services can be bundled with IPoS bundled with IPoS

SummarySummary

IPoS (TIA-1008) was developed by Hughes IPoS (TIA-1008) was developed by Hughes Network SystemsNetwork Systems

It is widely recognized within the It is widely recognized within the telecommunications community as the telecommunications community as the medium for transmission of IP Datagramsmedium for transmission of IP Datagrams

Think of IP and IPoS as two Think of IP and IPoS as two interconnecting highways. Where one interconnecting highways. Where one starts another ends and vice-versa starts another ends and vice-versa
