Many buildings and towers are leased property by RF communications providers and have warning signage regarding RF radiation. Roofers, other rooftop maintenance personnel and building tenants are understandably concerned with the hazards associated with Radio Frequency energy (NIRAD or Non-Ionizing Radiation) being emitted by this RF infrastructure.
ScanTech has full range capability of measuring RF emissions from virtually 0 Hz up to 90 GHz (X Band, K Band Ku Band, Ka Band, E Band, etc.) with a high dynamic range (from 0.001 mW / cm^2 to 265.3 mW / cm^2) to measure levels from well below to well above established safety standards established by the FCC, ICNIRP and Health Canada Safety Code 6 (2015). These standards include FCC OET 65 and ICNIRP 2020.
Also, 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 an RF radiation emissions testing survey as a part of due diligence to evaluate either what health hazards may exist or 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 RF 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 RF Radiation Compliance Safety Surveys with regard to MPE (Maximum Permissible Exposure) for antenna arrays, towers, repeaters and other radio frequency emitting equipment on rooftops, etc.
For a quote, please supply the following information:
1) Physical address of the facility and layout including rough square footage involved (Scope of Work) and also where the antenna(s) and / or cell / radio towers are located. If this is just a cell tower / radio tower, I STILL need a physical address. Pick one that is close to the site.
2) Contact information including email, best phone number(s) including a cell number
3) OFFICIAL company name (this will go on the Service Agreement and invoices) and the nature of your business / industry
4) Any significant information about the RF source such as how long it has been there and where it is mounted
5) Timeline to accomplish
6) Access logistics, onsite contact information and PPE required if any
7) What are your typical payment terms and what is your vendor vetting process like (what paperwork needs to be filled out for the on-boarding process IF needed as most of my work projects are “one-off” visits with no installation or physical contact with your infrastructure)
8) A brief narrative as to WHY you are requiring an RF / Radio Radiation survey or cellular tower field testing survey and consultation
Q. I’ve been asked by the Fire Department, Police, Public Safety, etc. of my city to perform a radio coverage test of some kind in this new / remodeled building as a part of getting our Certificate of Occupancy – do you perform such RF surveys? (also known as an ERCC or Emergency Responder Radio Coverage RF survey)
A. There has been a surge of interest and requirements in various municipalities / states regarding First Responders and other entities that ask for emergency communication surveys as part of the CO / permitting process for new and remodeled buildings that fall within certain criteria. Understandably in the event of an emergency situation, appropriate personnel should have reliable communication through their 2 way radios or other Radio Frequency communication systems. This is outlined in NFPA 1225 which is the overarching consolidated specification for the older NFPA 1221 and NFPA 1261 which covers in-building radio frequency strength threshold such as DAQ 3.0 and either a 95 – 99%+ coverage. NFPA 72 also covers certain aspects of RF coverage. There are also national and local ordinances which dovetail / overlap on top of these specifications and involve RF communication path survivability, battery backup, inspections and annual testing.
However, due to the high level of variance of brands, models, engineering quality, frequencies, manufacturing tolerances, battery power levels, and range of environmental scenarios such as building construction geometry, material, relative altitude, weather, operator knowledge / proficiency and so forth, ScanTech cannot offer this service at a cost-effective price or guarantee of performance. There is also a considerable specialized knowledge required in the areas of NFPA, (National Fire Protection Association) ICC (International Code Council) Nor can we recommend anyone else in particular because this is a specialty RF testing niche that carries potentially high risk.
What you are looking for is what is known as a ERCC (Emergency Responder Radio Coverage) survey and that involves systems such as DAS, (Distributed Antenna Systems) BDA (Bi-Directional Amplifier) systems or UDA (Uni-Directional Antenna) systems as well as exterior high powered donor antennas to connect to the EMS (Emergency Mobile Services) RF service network in that area. The other term for this is Emergency Responder Communication Enhancement Systems (ERCES). There are a lot of other acronyms related to this, but the biggest problem is finding a reasonable and honest survey that is NOT connected with a supply vendor. ScanTech is platform neutral and will never push or sell products and by the definition of how a structure is evaluated, you practically need to have familiarity with or have on hand systems that can supplement “dead zones” or areas of weak / unreliable reception.
Here are two companies you can contact that allegedly do consulting only (no product sales) in this field but ScanTech cannot guarantee what results and satisfaction you may have as we have no experience in utilizing them:

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,
>Hi I live in a large HOA and parts of the development have poor >cell service (4G).
I don’t do residential work or engage homeowners, and I certainly do 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.
>How do we define the issue(s) to address them at a community >level rather than for each home owner.
I do not offer arbitration services which would be required for something this involved – please see the above suggestion.
