Clear-Com Launches 900MHz Version of Intercom

At this year's 2011 NAB Show, Clear-Com launched its new Tempest900 900MHz digital wireless intercom system, complementing the company's Tempest2400. Tempest900 is available in the United States and Canada, while Tempest2400 is distributed worldwide.

Company officials said Tempest900 offers much of the same operation, menu structure, and look and feel as the Tempest2400 system. It is also available in two- and four-channel versions and comes with the same set of features as the Tempest2400, including the ability to operate in normal, split, and shared modes.

The difference is that Tempest900 may provide improved coverage in areas where more structural penetration is required and in large enclosed areas where multipath interference would otherwise be a factor, according to the company. The longer wavelengths and wider symbol width used in the 902 to 928 MHz frequency range allow Tempest900 signals to break through dense walls and other structural objects more readily, increasing the range for users and reducing potential loss of audio.

"In the world of RF technology there is rarely a single solution for all applications or all environments," says Stephen Sandford, product Manager of the Tempest wireless systems, in a statement. "Tempest900 was created to perform in certain applications that may not be appropriate for 2.4GHz or other technologies. In other cases, it can perfectly complement other wireless intercom systems such as the Tempest2400 to address specific communication requirements."

A single Tempest900 in normal mode can support between one and five full-duplex wireless users who always need the ability to talk on the intercom system. Via a BaseStation in split or shared mode, it can support an unlimited number of users who need to monitor the conversation and can share talk capacity.

A total of five Tempest900 BaseStations can be co-located and connected together via their party line or four-wire intercom connections, offering a maximum of 25 Tempest full-duplex wireless BeltStations operating in close proximity. To further expand a system, Tempest900 and Tempest2400 can be used together, so it is now possible to combine up to 15 BaseStations, using 10 Tempest2400s and five Tempest900s, according to Clear-Com.
