system is not a mandatory deployment according to the International Convention for the Safety of Life at Sea (SOLAS) [10-13].
One disadvantage of UHF
technology is that UHF
readers require line-of-sight, so they won't work if stored in pockets or briefcases.
The handset is also compatible with Motorola CLS/CLP, Kenwood and other UHF
radios (FCC license required).
A joint position among the ASMG member states in favour of a co-primary allocation in the UHF
spectrum for broadcast and mobile at WRC-15 would foster the option to roll out low-cost mobile broadband services in the future, especially in underserved areas.
By enabling interoperability between UHF
and VHF radios on the same network, federal agencies, National Guard units and civilian personnel will be able to coordinate more effectively in the event of a major incident or civil emergency.
From the standpoint of physics, military UHF
must be the preferred option to connect war fighters to each other and to their support systems.
To design a near-field and far-field UHF
RFID antenna, some structures have been presented.
The near-field RFID system is conventionally used at low frequency (LF, 125-134 kHz), high frequency (HF, 13.56 MHz), and ultra-high frequency (UHF
, 840-960 MHz) bands, but far-field RFID systems only operate at UHF
Since the launch of the first Ultra High Frequency satellite in 1978, several replacement UHF
satellite constellations have been launched as satellites neared the end of their life cycle and to support an increasing demand in UHF
) to reply back to the reader, which consistently can achieve longer range than a passive tag.
The software-defined CM300/350 VHF and UHF
air traffic control radios will provide Voice over Internet Protocol (VoIP) capabilities along with improved ground-to-air communications performance.
