Wireless Communication System Operates In Spectrum Unaffected for FCC February Reallocation Process

LAS VEGAS, NEVADA, SEPTEMBER 15, 2008—Clear-Com® Communication Systems, a Vitec Group brand, is taking another step in the evolution of its unique CellCom® digital wireless beltpack system with the newly enhanced CellCom® (formerly CellCom10) Version 2.0, to be displayed at LDI 2008 (Booth #668). The popular wireless intercommunication system now features enhanced beltpack capacity, Interrupted Foldback (IFB) functionality and improved group operations between beltpacks, party-lines and other external inputs.

Supporting Clear-Com’s strategy of providing ubiquitous communication, CellCom is a digital wireless intercom system based on a cellular architecture that offers license-free communication and can allow up to 20 beltpacks to roam seamlessly between remote active antennas. In addition, it operates in the 1.9GHZ frequency range, and will not be affected by the migration of competing wireless systems to the 2.4GHz range once the FCC in February 2009 performs its RF spectrum reallocation.

“In today’s busy broadcast environments, production staff members are expected to support multiple job functions, creating an increased need for wireless connectivity,� says Stephen Sandford, Clear-Com® CellCom Product Manager. “In Version 2.0, we have doubled the number of beltpacks that a base station can support, giving users the freedom to communicate while on the move and improving the crew’s flexibility and efficiency. It’s also a major plus that it operates outside the of 2.4GHz band, which will likely be a very crowded place after the FCC RF spectrum reallocation process�

Additional new features available in CellCom Version 2.0 include three configurable IFBs, allowing the user to assign IFB keys to any number of beltpacks, which can then be programmed to act as IFB talent receivers or as the originator of the interrupts.

“This integrated IFB capability allows the user to listen to audio feeds while enabling other users to interrupt that audio feed at any point,� Sandford says. “For example, a director using a beltpack has the ability to interrupt the broadcast feed to deliver instructions to a camera operator listening to the broadcast via an IFB key. This provides true standalone IFB system functionality with program source feeds and beltpack interrupts mixed and routed to beltpacks that act as wireless IFB receivers. The user also has the option of working in conjunction with other IFB systems where the interrupts are generated from the CellCom beltpack keys.�

Other new components include the Wireless Party-line groups. This feature allows the user to seamlessly mix party-line users, external inputs and beltpack users in the same group without

The new CellCom system is centered on a highly programmable 1RU base station from which an operator can manage and oversee all communications for up to 20 digital wireless beltpacks. The system can be controlled from both the bright front-panel display on the base station or remotely via an Ethernet-connected PC that runs the configuration software.

The base station links wirelessly to the beltpacks by the remote Active Antenna, which enables users to roam freely throughout the broadcast facility while maintaining consistent communication without loss of signal. All transmission takes place in the license-free 1.9GHz frequency band, which helps eliminate interference with other wireless products such as PCs, talent microphones, IFB and in-ear monitors.

Another key benefit of the system is that each wireless beltpack and wired intercom connection on the rear of the base station has its own full-duplex port. The voice communication from each port is sampled, mixed and re-routed throughout the system as desired. As each wireless beltpack has its own timeslot, it can be individually addressed by the base station, allowing multiple combinations of beltpack-to-beltpack and small-group conversations to be held simultaneously.

Note: Due to trademark limitations, CellCom® products, including CellCom Version 2.0, are available in the U.S. and Canada only. In all other countries, the FreeSpeak® brand represents the same digital wireless intercom system (with minor technical differences). FreeSpeak 2.0 is making its debut at IBC 2008, September 12-16, 2008, Amsterdam RAI Centre, Stand 9.C40a.
