We provide a variety of services related to the wireless industry.
H&E has performed hundreds of studies for wireless telecommunications base stations, or cell sites, throughout the West Coast. A radio frequency (RF) exposure study examines conditions for a proposed wireless telecommunications base station or for proposed modifications to a base station and includes a written report, suitable for filing with permitting agency.
In order to complete an RF study, we need to receive:

RF exposure vocabulary:
Many telecommunication carriers find it convenient to co-locate with other carriers, or perhaps a wireless base station is located near public safety antennas. In such cases, an interference or IMD study can be useful. Our IMD study examines existing frequencies in use and proposed frequencies at a wireless telecommunications base station to assess interference from proposed operations to existing or other proposed operations. Includes written report, summarizing results.
In order to perform a study, we need to receive:

Most of our H&E engineers have testified as expert witnesses in court, at hearings, or meetings on behalf of clients. We are credentialed by professional registration and by experience, and our expert qualifications are generally recognized and accepted on both sides. Increasingly as public concerns grow over RF exposure issues, we assist clients by explaining technical concepts to lay audiences.
