Northrop Grumman’s European subsidiary, Northrop Grumman Park Air Systems, has added voice over internet protocol (VoIP) capability to its range of air traffic management radios.

The firm is offering the VoIP facility to meet the demands of the air traffic management (ATM) environment on the PAE T6 range of VHF and UHF radios.

Northrop Grumman Park Air Systems managing director Charles Houseago said that as telecom networks migrate to internet protocol capability, ATM providers will be able to benefit from the cost and performance improvements that these networks offer.

The PAE T6 radios deliver VHF digital linkmMode 2 (VDL-2) data link radios with integral IP communications to support next generation data communications applications.

The PAE T6 will continue to support legacy interfaces including E1 and traditional analogue connections to allow seamless integration with a wide range of established systems and networks.

The Northrop subsidiary supplies ATM systems for air-space operations worldwide.
