C4i has received a contract modification for the delivery of its SwitchplusIP end-to-end Internet Protocol (IP) voice and data communications system to the Royal Thai Air Force (RTAF).

The contract extension follows the original contract awarded to the company in 2008 for the delivery of the air defence system to the RTAF. The SwitchplusIP voice and data communications system consists of over 20 operational sites linked together by an advanced IP network throughout the country, to provide a true ‘system of systems’ solution.

Following the initial deployment, the system can be easily expanded to accommodate additional sites, operators or assets including a mobile air traffic control system that can be networked, allowing Command Centre operators to utilise and communicate with remote assets and operators through the IP network.

The system is available in three variants; a mobile-dismount IP-based system for in-vehicle or dismount applications; command-post for larger single-site applications; and command-centre for distributed, multisite applications.

C4i’s managing director Peter Harrison said the SwitchplusIP system will provide operators with transparent access to communication assets located all across the country. The SwitchplusIP can also be used for mission-critical applications such as military operations centres, transport command and control, public safety applications and transportable vehicle-based communications solutions.

Deliveries under the contract are expected to take place in the first quarter of 2012. The communications systems are also used by the US Department of Defense, Australian Defence Force, Croatian Air Force, Singapore, New Zealand and the Republic of China Navy.
