The use of DECT technology for wireless communication in Broadcast has proven to be very effective for many studio talkback applications requiring full duplex operation. However, to achieve adequate coverage in a large facility, it required a complex and expensive arrangement of base stations, antennas and cabling. Now, Trilogy’s advanced IP DECT wireless platform provides a scalable infrastructure with simple interconnection of combined base stations and antennas over a standard IP network.

The IP DECT system offers many advantages over traditional UHF or VHF wireless equipment, with no frequency allocation and licensing issues to worry about and at a much reduced cost.

With up to 8 simultaneous channels in a network, and automatic handset tracking, the system is ideally suited to all Studio and Broadcast centre applications where operator mobility is required. The handsets are extremely robust and are suitable for all production personnel (Cameramen, Floor Managers, Lighting Crew etc) as well as engineers ‘on the move’.

Users can move freely throughout a building, or anywhere within range of a base station, with no interruption in communications. Indeed, the system is not limited to fixed studio environments, as base stations may be easily deployed throughout even the largest sports or entertainment venue, and without the technical constraints found with placement of UHF antennas.

Utilising SIP (Session Initiation Protocol) the IP-DECT system supports Trilogy’s Gemini and Mercury IP audio and control messaging, allowing mobile users to select to communicate in full duplex with individual and groups of operators in the main intercom system.

Similarly, Gemini or Mercury intercom panels can select to call specific handsets or entire user groups, as can any SIP enabled mobile phone, further extending the reach of the entire communications network.

Simplifying installation a simple web browser is used to configure IP addressing, static or DHCP operation and CODEC parameters for each base station.

Example Application Scenario The IP-DECT system may be specified in versions to suit DECT legislation in Europe, North and Latin America and can be supplied with a range of headset and charger options.
