Cassidian and Astrium Services interconnect regional Tetrapol networks via satellite

Cassidian and Astrium Services have added a a new dimension to the Tetrapol standard by creating the possibility of interconnectign regional networks over satellite. 

A live demonstration recently took place in Brazil with the aim of showcasing an end-to-end communications solution for border surveillance and to demonstrate what features can be added to a Tetrapol network when interconnected via satellite. 

Secure radio communication via Tetrapol networks from Cassidian are already in use by the Brazilian federal police department, Departamento de Polícia Federal. Nine regional Tetrapol IP networks ensure reliable coverage from the country's Atlantic coast to the Brazilian borders with Peru, Venezuela, Argentina and seven other countries. 

Tetrapol regional networks are usually interconnected using terrestrial connections. In remote areas like the Amazon Forest where terrestrial telecommunications infrastructure is poor or nonexistent, the Astrium Services’ SKYWAN technology can now enable the interconnection of several networks over satellite with DAMA technology to share bandwidth between all the nodes. 

Thanks to the scalability of the Tetrapol solution, a wide set of Tetrapol services can be offered with a tactical temporary or permanent regional coverage. The satellite link also provides Internet access, video and other applications in parallel to the Tetrapol voice communication to remote locations, thereby providing a wide range of data transmission capabilities. 

Oriximiná (pictured), where the demonstration took place, is a small city situated on the Amazon in the North of Brazil, is best reached by a four hour boat trip from the city of Santarém. Its remote location was chosen to simulate the harsh environmental conditions that border surveillance groups face on a daily basis. 

Attending the demonstration were representatives of the Brazilian Ministry of Justice as well as several federal agencies involved in border surveillance. Astrium Services and its partner Cassidian (both EADS companies) presented a showcase exhibiting simultaneous voice, video and internet transmissions to separate handheld devices, all while maintaining perfect network stability and excellent voice quality. 

Captain Albércio from the Brazilian National Force said: ‘We have been seeking a solution like this for over four years. The National Force is required to operate faultlessly also in remote areas throughout Brazil, like the Amazon Forest and on the outmost points of the Brazilian Border. 

‘This all-in-one solution provided by Astrium Services and Cassidian combines satellite communications with digital radio trunk in such a way that the troops will have mission-critical digital radio and Internet access in the midst of the jungle and can stay connected with our headquarters in Brasília. 

‘Beyond that we have the possibility to connect with the radio backbone of the Federal Police which will allow us to have access to information from all Brazilian States. For sure it will increase the safety and the effectiveness of our operations.’

Through its ND SatCom product range, Astrium Services is a leading global supplier of satellite-based broadband VSAT, broadcast, government and defence communication networks and ground station solutions. Its innovative technologies are deployed in broadcast and media, enterprise and telecom environments, as well as government and defence, worldwide.
