The 1815 MHz band ranges from 1780~1850 MHz. In 2014, the FCC in collaboration with NTIA reallocated the 1755-1780 MHz band to commercial wireless use. Most of the federal systems now operating in the 1755-1780 MHz will compress operations into the 1780-1850 MHz portion of the band. Operations in the 1780-1850 MHz band consist of military tactical radio relay, tracking, telemetry, and control data communications. Federal agencies also use this band for law enforcement, video surveillance, robotics, 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 1815 MHz have the ability to propagate further distances via two mechanisms: penetration and diffraction. Penetration refers to 1815 MHz waves ability to penetrate through building walls, vegetation and other obstacles. 1815 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 1815 MHz wave that it can go around an object such as a building or vegetation. 1815 MHz waves have smaller Fresnel zone.
