Compliance with FCC Human Exposure to Radiation and RF Susceptibility of Medical Instruments 

HARTECH has performed rigorous studies of radiation susceptibility of medical electronic (ME) equipment to radio transmitters. These include handheld radios used by public safety agencies, external radio transmitters and new internal hospital systems. As more and more wireless medical instruments are introduced into hospitals, radiofrequency radiation can effect the readings of both life sustaining and non-life sustaining instruments. HARTECH performs studies in hospital environments to determine whether RF radiation meets FDA (ME equipment International standard IEC 60601-1-2) and FCC RF susceptibility standards. 

HARTECH specializes in making calculations per FCC OET Bulletin 65 "Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields" to make sure the FCC standards are met. Every station license applicant must certify they meet those standards. At highly complex sites with a multitude of RF sources, HARTECH is available to make radiation measurements and certify the site is within the standards.

Performing Modeling Services to Assure Successful Transmission

HARTECH performs highly technical and specialized computer analysis to assure a client that an adequate line of sight exists between two proposed microwave terminals. Analyses are customized to meet the specific requirements of each customer's situation. Our experts use a 30 meter topographic data base equivalent to USGS 7 1/2 minute quad maps to provide elevation data at specific latitudes and longitudes. These modeling services have been utilized to develop many radio systems in rugged terrain including the Rocky Mountains as well as in flat terrain.

HARTECH also assists clients by generating the Federal Communications Commission (FCC) contours for broadcast and two-way radio applications and to predict coverage of radio systems through modeling. Additionally, our sophisticated programs enable us to analyze all radio frequencies at a given site and determine potential interference.

Aiding in Evaluating Cellular/PCS/Two-Way/Paging Sites

HARTECH aids governmental agencies in evaluating radio/wireless siting proposals for site permits. We also work with governmental agencies in reviewing and updating their rules and regulations. Public Wireless Systems (PWS) including cellular/PCS services have only begun a major proliferation of new sites as phone and broadband capacity increases are required.

Designing Two-way and Microwave Radio Systems to Meet Each Client's Unique Needs

HARTECH has proven its ability to design analog and digital radio systems and to give clients a competitive edge for more efficient and effective communications.
