Smart Radio RM-1690 Summary Datasheet

The 1690 MHz band ranges from 1670~1710 MHz. In 2014, the FCC in collaboration with NTIA reallocated the band to commercial wireless use. Operations in the 1690 MHz band consist of military tactical radio relay, air combat training systems, tracking, telemetry, and control data communications for control of spacecraft. Federal agencies and the military also use this band for law enforcement video surveillance and robotics, terrestrial telemetering operations for aircraft, missile flight testing, fixed point-to-point microwave relay communications and unmanned aerial systems.

This band’s transmission characteristics make it desirable to achieve a good balance of range and penetration for mobile ground-based robots. The RF signals at 1690 MHz have the ability to propagate further distances via two mechanisms: penetration and diffraction. Penetration refers to 1690 MHz waves ability to penetrate through building walls, vegetation and other obstacles. 1690 MHz waves can go through multiple building walls making it an excellent choice for applications that do not have a direct line of sight between sender and receiver. Diffraction describes the characteristic of a 1690 MHz wave that it can go around an object such as a building or vegetation. 1690 MHz waves have smaller Fresnel zone.
