Which band is associated with GPS, Bluetooth, and cell phones?

Explanation:
UHF, which runs roughly from 300 MHz to 3 GHz, is the band that covers these technologies. GPS operates at about 1.575 GHz, which sits in the L-band but within the UHF range. Bluetooth uses 2.4 GHz, clearly inside UHF. Cellular phones operate across frequencies in the 800–1900 MHz area in many regions, all well within UHF. These systems rely on higher frequencies to allow compact antennas and practical data rates for portable, line-of-sight communication, which is why they all sit in the UHF band.
