EME/NIR (RF Emissions) Studies

What is an RF Emissions Study?

photoThe FCC has set limits on human exposure to RF energy and has mandated that every time the RF environment at a wireless site is modified, a compliance study must be run to verify that the site is still within compliance to the FCC's limits. Sitesafe provides independent, professional, third-party compliance studies that meet the FCC's mandate and provide our customers with an increased level of liability protection. These studies can be performed on any type of wireless facility—tower, rooftop, water tower, etc.—and we have certified more than 20,000 rooftops and towers for RF compliance.

EME Site Visit and Analysis: Rooftop Sites

A site analysis is conducted 1) to collect site data that is not readily available, 2) take actual point-in-time EME measurements, and 3) to verify that proper safety procedures are being maintained. The data collected includes the site dimensions and photos, locations and identifications of all transmit antennas, and EME measurements throughout the site. Our technicians verify that the proper safety practices are in place at the site, such as: access to the site (restricted or open), appropriate safety signage, and availability of a site safety plan detailing hazardous regions. All collected data is entered into Sitesafe's proprietary RF exposure modeling software, which creates an RF exposure model. The model is then analyzed and a report is generated to certify compliance with FCC regulations, or necessary steps are outlined to attain compliance.

EME Site Modeling Report

A site modeling report uses customer supplied information including drawings, pictures, and antenna/transmitter specifications. These data are assembled and Sitesafe's proprietary RF exposure modeling software is used to predict the RF levels on the site. The model is then analyzed and a report is generated that either certifies compliance with FCC regulations or outlines recommended steps to attain compliance.

Non-Ionizing Radiation (NIR) Study: Theoretical Assessment

Sitesafe can conduct an analysis with no actual site visit on a tower or similar stand-alone structure by calculating the theoretical ground exposure (MPE) at the base of the tower assuming the "worst case" effective radiated power (ERP). Sitesafe provides a Tower Emissions Certification Letter that acknowledges the calculated results, demonstrates site compliance and provides standard site safety recommendations. This letter of certification serves as an independent analysis of the RF environment and can be used to demonstrate compliance with FCC regulations in the event of an audit or local zoning issue.

Site Safety Plan

A Site Safety Plan includes procedures to be followed for allowing access to the site, working in the RF environments, posting hazard signage and adding additional tenants to the site. The plan is an important element in maintaining a site that is in compliance with OSHA's guidelines for safe work practices in a hazardous environment. Sitesafe can provide a detailed site safety plan based on your exact site conditions upon request.
