Cellular Tower Strength Surveys for RF Radiation Safety (MPE) 5G Cell Phone Signal and Rooftop Antenna Surveys

Cellular Tower Strength Surveys for RF Radiation Safety (MPE) 5G Weak Cell Signal and Digital TV / WiFi – Wireless Coverage

If your company or property is frustrated by dropped calls, slow data downloads and “Out of Service Area” messages on your smartphone, Android cell phone, iPhone, PDA, etc. ScanTech can help. We measure the signal strength (both overall spectral amplitude and by individual frequency block) of all major carriers such as Verizon, T-Mobile / Sprint and AT&T on 2G, 3G, 4G, 5G, LTE, PCS and AWS networks. We also measure digital TV signals in remote areas of the United States where broadband cable / DSL / optical carriers are not readily available.

Also, if you have a prospective property you are investigating and need a survey as a part of due diligence to evaluate what cell phone coverage will be, we can gather data that will identify weak signal areas and help point towards cost-effective solutions.

There are several reasons for poor reception which includes:

  • Geography such as being in a low lying area with respect to a cell tower (elevation) or linear distance to the nearest tower(s).
  • Cell tower antenna orientation and power (ERP or Effective Radiated Power) with respect to your specific location. There is a tradeoff between directionality and gain from any given antenna. The more directional the antenna, the higher the gain, but also the lower the power in directions where it is not aimed. Sidelobes also waste power in directions that the antenna is not aimed in.
  • Attenuation caused by distance, elevation, significant terrain, (such as hills, valleys, lakes, mountains, etc.) trees and vegetation, building materials, (all of them weaken RF to some extent including glass) large equipment, areas that are heavily shielded by plate or “chicken-wire” metal, and “shadowing” from other nearby structures.
  • Heavy cellular subscriber bandwidth loads at peak times
  • Destructive interference caused by complex cellular RF reflections bouncing off of objects and creating null zones at critical nexus points.
  • Poor sensitivity and / or low signal to noise (SNR) ratios of the end user device which can vary by manufacturer, model, manufacturing variations, physical damage, firmware, etc.
  • Localized RF interference such as WiFi, wireless microphones / audio setups, or other equipment such as cell phone RF jammers.

We also perform FCC RF Compliance Safety Surveys with regard to MPE (Maximum Permissible Exposure) for antenna arrays, repeaters and other radio frequency emitting equipment on rooftops, etc.

    Hi I live in a large HOA and parts of the development have poor cell service (4G). How do we define the issue(s) to address them at a community level rather than for each home owner. Important to us as it affects out ability to contact HOA Maintenance staff during the business day or off hours snow or other storm clean-up.

    Jim,

    I don’t do residential work or engage homeowners, and I certainly would not want to deal with an HOA. I suggest you contact either the Better Business Bureau or an attorney. It sounds like a real mess with complications arising from the terrain, vegetation, diversity of cellular phone carrier services and phone models.

    I do not offer arbitration services which would be required for something this involved – please see the above suggestion.
