The WDM8000 Data Radio Transceivers are designed primarily for data transmission and reception.
The design of the WDM8000 is based on the state of the art technology and the modulation is FFSK orGMSK. The WDM8000 Data is designed for 7.200 / 9.600 bps or 9.600 / 19.200 bps data transmission on ordinary 12.5, 20 or 25 kHz channels on any of the PMR frequency bands.
VHF low: 39-41 MHz
VHF low: 68-88 MHz
VHF high: 135-174 MHz
UHF1: 335-405 MHz
UHF2: 400-470 MHz
The Wireless Data Radio WDM8000 is built into a robust metal housing, which can be mounted on a DIN rail or on a plane surface by using brackets forming a part of the cabinet.
The SMA connector of WDM8000 gives the option to mount the antenna either directly on the modem or with an external antenna.
Programming of parameters such as configuration of the data interface, radio frequencies, power output (up to 5 Watts), etc. is performed by using a standard PC, through the built-in RS232 interface and dedicated software.
The WDM8000 series fulfils the European standards for data communication products and is manufactured and tested using the latest technology in order to achieve the optimum quality.
The WDM8000 is available for mobile and fixed applications.
For mobile users the design of the WDM8000 makes it possible to implement an internal GPS receiver in connection with systems in which such facilities could be appropiate.
