Trimble Offers License-Free Radio Solution for Robotic Total Stations

New GeoRadio 2.4 GHz Provides High-Speed, Long-Range Data Link that Reduces Radio Interference on Busy Job Sites

SUNNYVALE, Calif., May 21, 2004 – Trimble (NASDAQ:TRMB) today introduced the GeoRadio 2.4 GHz for surveying applications using robotic total stations. The new radio solution allows for license-free use in most areas worldwide. By using state-of-the-art spread spectrum technology, the compact, low-power GeoRadio 2.4 GHz reduces radio interference and resists jamming for superior performance on busy job sites.

By using the globally available 2.4 GHz Industrial, Scientific and Medical (ISM) devices band, the GeoRadio eliminates the need for licensing. Rather than using a fixed channel, the radio’s spread spectrum technology enables signals to ‘hop’ over a wide range of frequencies. The sending and receiving radios change frequencies in unison, creating reliable communications over a spread of frequencies and reducing the vulnerability to interference, jamming and multipath fading. The Trimble GeoRadio 2.4 GHz uses the frequency range 2401 to 2470 MHz. 

The 100mW GeoRadio 2.4 GHz system also provides a long-range radio link that reaches up to 1,200 meters (3,937 feet). Users can measure more points without moving the total station, increasing efficiency and productivity on the job site.

Easy to use and versatile in functionality, the GeoRadio 2.4 GHz radio is controlled by the user’s choice of field software, whether it’s the Trimble Survey Controller, Trimble Survey Pro or Geodimeter CU software. The user can even switch the radio on and off through the software. The integrated solution can also be used with the Trimble ACU, TSCe and TDS Recon Controllers.

The GeoRadio 2.4 GHz is fully compatible with the Trimble 5600 Total Station Series and the Geodimeter 600 series and will be offered as an upgrade for existing users. The GeoRadio 2.4 GHZ is expected to be available mid-June of 2004 through Trimble’s Geomatics and Engineering dealer network.
