WMTS Frequency Coordination
Coordinate your WMTS frequencies quickly and easily

Welcome to the online interactive Wireless Medical Telemetry Service (WMTS) Frequency Coordination System, wmtssearch.com. The American Society for Healthcare Engineering (ASHE) selected Comsearch as their technical partner in providing frequency coordination services in the WMTS bands. The WMTS Frequency Coordination System allows you to quickly search for available WMTS frequencies, register them in the database, and download your coordination certificate.

In response to growing concerns about interference resulting from new digital television transmitters, low power television transmitters, and greater use of Private Land Mobile Radio equipment, the Federal Communications Commission (FCC) established the Wireless Medical Telemetry Service (WMTS), dedicating bands of frequencies for interference-free operation of medical telemetry systems. The WMTS bands are 608 - 614 MHz, 1395 - 1400 MHz, and 1427 - 1432 MHz. All transmitters operating in the WMTS bands must be registered in the database to ensure interference-free operation.

WMTS registration is easy, just follow these easy steps:

Step One: Contact ASHE to register the main facility or hospital where WMTS equipment will be installed. ASHE will issue a login and password to provide access into the WMTS Frequency Coordination System. If you have already registered with ASHE, proceed to Step Two.

Step Two: Use your login and password to access the WMTS Frequency Coordination System. Here you will enter the pertinent data for your specific WMTS deployment, conduct a frequency search, and download your coordination certificate.

Comsearch also offers the following WMTS Frequency Coordination Services:

• Coordination with the National Science Foundation (NSF)
  The 608-614 MHz band is shared with the radio astronomy service. There are 13 radio astronomy sites located throughout the United States. These sites have a protected radius of up to 50 miles. If your proposed WMTS deployment should fall within the protected radius of any of these sites, it is necessary to coordinate with the NSF. Comsearch will be automatically notified if your deployment falls within any of these protected radii, and we will initiate the coordination process with the NSF on your behalf.
• Coordination with the National Telecommunications and Information Administration (NTIA)
  The 1395 - 1400 MHz is shared with military radar systems. There are 17 radar sites located throughout the United States. These systems can have a protected radius of up to 55 miles. If your proposed WMTS deployment should fall within the protected radius of any of these sites, it is necessary to coordinate with the NTIA. Comsearch will be automatically notified if your deployment falls within any of these protected radii, and will initiate the coordination process with the NTIA on your behalf.
• Interference Analyses
  In situations where the WMTS Frequency Coordination System yields no available frequencies, Comsearch recommends that the user conduct a detailed interference analysis in order to assess the interference potential and possibly minimize the distance separation criteria. Comsearch will work to identify the physical parameters of the systems, and we will conduct a detailed analysis of interference potential between your WMTS system and the potential interference case.
• Training
  Need help understanding WMTS and how to perform frequency coordinations? Comsearch can come to your facility and provide hands-on training on how to use the WMTS Frequency Coordination System. This training class will also explain the complexities of deploying a WMTS system and why frequency coordination is important. We will also help you better understand interference mitigation and assist you in designing and deploying a system that minimizes interference potential.
