Human Exposure to Radio Frequency Fields: Guidelines for Cellular
At a cell site, the total radio frequency (RF) power that can be transmitted from each transmitting antenna depends on the number of radio channels (or transmitters) that have been
Emergency Medical Services Radio
The UHF frequencies are assigned in pairs. In semi-duplex mode the higher frequency of the pair is usually used by the mobile while the lower frequency is used by the base (usually a hospital).
Base stations and networks
The intensity of the radio waves is drastically reduced as the distance increases from the base station antenna. On the ground, in houses, and other places where people reside, the exposure levels from

FCC Human Exposure to RF-EMR: Guidelines for Cellular Antenna Sites
On a WTF, the total radio frequency microwave (RF/MW) radiation that can be transmitted from each transmitting antenna depends on the number of radio channels that have been authorized by the
ICNIRP | Base Stations
Base stations emit radiofrequency electromagnetic fields (RF EMF) in the range from several hundred MHz to several GHz. The exact frequency bands used differ between technologies (GSM, UMTS,
Land Mobile Radio (LMR) 101
Figure 2 depicts a basic LMR system that shows the flow of communication between emergency responders using portable or mobile radios, which are connected to a network of base stations,
What Is an Emergency Responder Communications Enhancement
When the signal can''t get to the portable radio due to interference, an emergency responder communications enhancement system needs to be installed to amplify and repeat the
Public Safety Primer
Police radio and other public safety services, such as fire departments and Emergency Medical Services (EMS), have traditionally been found in the VHF and UHF parts of the spectrum (45MHz, 150MHz,
