Higher frequencies can use less power, but will reflect off of dense surfaces. The 900MHz radio system is at a lower frequency and will penetrate surfaces more easily . Tempest 2.4GHz systems are more reflective and tend to be affected more by bodies, foliage, or moisture that can attenuate the signal.

The V-band as defined by IEEE is a frequency range from 40 to 75 GHz . IEEE uses letters to signify a range of frequencies from 1 to 110 GHz. The V-Band is license free in many countries and is most often used for wireless backhaul and point to point/point to multi-point radio links.
Read moreWhat is a band in communication?
In telecommunication, a band – sometimes called a frequency band – is a specific range of frequencies in the radio frequency (RF) spectrum , which is divided among ranges from very low frequencies (vlf) to extremely high frequencies (ehf).
