What is aN RF Emissions Study?

A radio frequency (RF) emissions study is a comprehensive evaluation of the electromagnetic energy (EME) emitted from both tower and rooftop RF transmission sites. The findings of this evaluation are compared to the Federal Communications Commission (FCC) guidelines for human exposure to RF radiation and to Occupational Safety & Health Administration (OSHA) guidelines for safe work practices in and around hazardous environments.  

The FCC mandates that the RF emissions levels be calculated and kept on file. This file then needs to be updated every time there is a change in the RF environment.

Why Conduct aN RF Emissions Study?

The RF emissions study provides the following benefits:

 

 

 

RF Signage is required when:

 

Sample Customer Measurements:

Below you will find a sample Field Measured RF Analysis in conjunction with a Predicted RF Computer Model & Analysis.  Based on the measurements below our customer rooftop indicated a few hotspots of Radio Frequency Fields (RF) which exceed FCC Limits for RF Exposure.  3Z Telecom assisted this customer by restricting public access to these hotspots.  In addition, we posted signage notifying all personal accessing the roof that Radio Frequency fields may exceed the FCC Rules for Human exposure. The customer was provided our detailed RF Emission Compliance Report indicating compliance with FCC Regulation. The customer now has peace mind and can rest easy.

Don’t let this happen to you: This Antenna is Emitting High RF Energy in the direct path of a stair case.  The general public and workers using this stair case must be notified of this potentially harmful RF Hotspot; RF Signage is required.  In addition a Site Safety Plan must be developed to turn off/ deactivate the Radio Waves Emitting from this antenna when this stair case is in use.

Description of 3ZTelecom’s Core Services?

• Radio Frequency (RF) Emission Study
  Data collected includes the site dimensions & photos, locations & identifications of all transmit antennas, and EME measurements throughout the site. This data is used to create a site EME profile using our RF exposure modeling software. In addition, our technicians verify that the proper safety regulations 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.
  
  
• Predicted RF Computer Modeling & Analysis
  An analysis can be conducted with no actual site visit on a tower or similar stand-alone structure by calculating the theoretical ground exposure (maximum permissible exposure - MPE) at the base of the tower assuming the "worst case" effective radiated power (ERP). We will provide a Tower Emissions Certification Letter that acknowledges the calculated results, demonstrates site compliance and provides standard site safety recommendations. This letter of certification then provides 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.
