How much RF exposure should a cell site transmitter have?

In the case of cellular and PCS cell site transmitters, the FCC's RF exposure guidelines recommend a maximum permissible exposure level to the general public of approximately 580 microwatts per square centimeter.

Why do cellular phone transmitters emit RF radiation?

Cell phone and two-way radio transmitters are typically lower power. Pager, cellular telephone base station and two-way radio antennas often emit RF radiation in short “bursts.” The strength of the signal surges when these devices are utilized. For instance, RF exposure can only occur when a radio is keyed. Otherwise, the transmitter is inactive.

What is a cellular base station antenna?

Commonly used cellular base station antennas are of the panel type, usually around one foot wide by four to six feet tall, and may be arranged in a triangular formation as a cluster of antennas to serve three sectors. A “hot zone” is a location where a high RF field exists that exceeds FCC limits for exposure.

Where should you not go if you have a radio station?

There are some areas (such as previously mentioned TV and radio broadcasting sites) where no one should go, unless the equipment is powered down and taken off-line due to the hazards of being in close proximity to the broadcast antennas. Effects of RF Radiation

How much RF energy does a rooftop antenna use?

They range from one to five megawatts of effective radiated power. These are the strongest sources of RF energy found on rooftops and particular caution should be used if required to access regions near the actual antennas. Understanding RF Signals

What is an in-building emergency responder Communications Enhancement System (Erces)?

An In-Building Emergency Responder Communications Enhancement System (ERCES) is a wireless communications system used by first responder and emergency services personnel, such as police, fire, emergency medical, homeland security, and disaster response agencies.
