Our environmental services address several industries and government/regulatory bodies, primarily:

• Environmental agencies
• Energy authorities
• Telecommunication regulatory authorities
• Mobile telecommunications operators

Metocean (Meteorological and Oceanographic) Systems

Measurement of air, winds, waves and tides for data for analysis purposes: Meteorological (wind speed and direction, air temperature, air pressure, relative humidity, rainfall and visibility) Oceanographic (waves, tides and currents) and). This includes both real-time measurement and transmission via standard (e.g. GSM or TETRA) or bespoke technology, as well as remote collection for laboratory analysis.

Together with our strategic partners we can provide complete turnkey solutions.

Radio Frequency Hazards

        MPE Calculation

• RF radiation analysis is conducted in accordance with the FCC OET 65 MPE Standard and is performed to calculate near field and far field RF radiation levels for controlled (occupational) or uncontrolled (general public) for (a) on tower (b) off tower, and (c) rooftop configurations

        MPE Field Measurement

• Often it is not possible to calculate the RF radiation levels at a site due to lack of information concerning the antenna, frequency and power configurations used at a multi-carrier site or an antenna farm. In such cases, on site measurements of the RF radiation is recommended. The process entails travelling to the site with measuring equipment and making measurements to collect RF data to prepare the MPE report.

Zoning and Expert Witness

        Expert Witness Testimony

• Bridge Connect US offers litigation support and expert testimony services. Our expert witnesses are specialised in technical subjects including telecommunications, wireless communications, as well as electronic and electrical subjects. Our experts have experience in providing support before, during and after trials and regulatory procedures. This includes cases concerning damages resulting from mismanagement, breach of fiduciary responsibility, fraud and wrongful death, as well as administrative law cases involving compliance with US federal and state regulatory rules. In addition, we can provide expert witness testimony and assistance for any telecoms and wireless related to any zoning hearings involving RF radiation and tower siting.

        FAA Airspace Analysis

• Airspace analysis is often performed for Greenfield sites and existing structures to determine if the proposed structure height would interfere with instrument approach procedures. FAR Part 77 and TERPS are the basis for airspace analysis. While these rules and standards are complex and can be difficult to explain to sponsors of proposed towers and buildings, a study and report can show any potential problems to air navigation safety. FAA Notification for a proposed new structure or for alterations to an existing structure is not always required. However, a determination is recommended for any new tower or any alterations to existing structures in order to maximise liability protection and provide peace of mind. To obtain an FAA determination, an FAA notification is required. This requires the preparation and submission of an FAA Form 7460 along with supporting documents. Along with the form's submission to the responsible FAA office, monitoring the progress of the FAA's study and ensuring its completion is part of the service.

        FCC Licensing

• US FCC microwave licensing includes frequency coordination procedures and the preparation and submission of the FCC application forms. We can complete the frequency coordination procedures and documentation, as well as the completion of the engineering portions of the application. FCC Notification is required prior to the 5th and 10th year anniversaries of the PCS license issuance date. The FCC requires each PCS licensee to prepare and file a notification that the PCS licensee's network has reached its minimum required coverage benchmarks. We can prepare the engineering portions of the FCC notifications along with all the supporting documents and maps. FCC Tower Research shows for any given site, whether the tower owner is required to register the tower with the FCC. FCC Tower Registration requires the preparation and filing of an FCC Form 854. This submission ensures that the FCC tower registration can be completed in a timely manner.

        FCC Intermodulation Analysis

• Study Phase I
  For each site, we obtain the pertinent data on all users' transmit and receive frequencies, completion of intermodulation product calculations, and the delivery of a study showing the results and identification of any potential problems.

• Study Phase II
  This is a more detailed analysis. Normally it is not undertaken unless there are specific frequency interference problems at the site. Phase II involves calculating the intermodulation product signal levels as well as transmitter noise/receiver desensitisation analyses. A report is prepared and delivered based on actual site conditions utilising (a) manufacturers' transmitter noise and receiver de-sense curves, (b) vertical and horizontal space isolation graphs, and (c) insertion and rejection losses for duplexers, band-pass/notch cavity filters combiners, isolators, pre-selectors, and other filter and multi-coupling devices.
