Clear-Com Storms Into Vegas With Tempest Wireless Intercom
Clear-Com, a Vitec Group brand, will debut Tempest 2400 and Tempest 900, a wireless intercom system, at NAB2007. The new Tempest has been engineered to avoid the need for licensing and frequency coordination. Utilizing Frequency Hopping Spread Spectrum in conjunction with TDMA technology, Tempest operates in both the 2.4 GHz and 900 MHz bands.

Tempest is a timely solution to a problem wireless communication system users will face upon the completion of the DTV transition in early 2009. Those who have been operating wireless equipment in the 500-600 MHz portion of the UHF band will find that spectrum crowded with UHF DTV transmissions. The 700 MHz band will not offer solutions because those frequencies are slated for auction and public safety uses.

Operating in the unlicensed 2.4 GHz and 900 MHz bands, Tempest is unaffected by the reallocation of the UHF-TV spectrum. State-of-the-art 2xTX Transmission Voice Data Redundancy sends each packet of audio data twice on different frequencies, and through different antennas, which assures uninterrupted, high-quality audio communications.

Tempest can interoperate with other Clear-Com intercom systems and those from other manufacturers through four-wire and two-wire connections. Each base station can operate up to five wireless belt stations, and by stacking up to 15 base stations together, 75 independent wireless belt stations can be integrated into the intercom system.

Clear-Com will be in booths C5912 and C8725.

With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
