Car-mounted radio of the digital wireless communication 

Range of application:

NT868 car-mounted wireless radio is a kind of anti-interference that is offered for the army and special department, radio of the secret communication, have data transmission and digital speech function, used for moving and fought the individual soldier in the forefront and connected with mainly, such departments needing to prevent terror from attacking as the equipment , airborne troop , customs , frontier of communication commanding , special force while arranging ,etc., can be regarded as the terminal of SPD-2000 digital trunking systerm.
 
Property summary:

NT868 car-mounted radio adopts the latest wireless and baseband technology, it has the secret algorithms that it is unable to decode the figure up to 96 digit, per second 10 jump of anti-interference ability.The GPS module of inside is regard as GPS mobile terminal. The data transmission interface linking with PC directly, can offer the speed of 9.6—19.2Kbps. There are Perfect network scheme and order. High sensitivity , clear speech, compatible simulation converses.
