Wireless has taken Healthcare by storm. From wireless LAN's to patient monitoring networks, from wireless PBX's to paging systems, from asset tracking to cell phones, today's hospitals are taking full advantage of the mobility, flexibility and speed of wireless technologies to improve the quality and reduce the cost of patient care. Add these technologies to the existing wireless infrastructure including walkie-talkies, aviation radios, security, wireless signaling, and building monitoring systems, then couple this with other devices such as fluorescent lights, power distribution systems, and microwave ovens—and then consider the interaction of all these systems with sensitive medical equipment, and it's easy to see that the RF environment in the hospital is one of the most complex known today.

Do you know what radiating devices are in your hospital, and which are susceptible to RF interference? Do you know all the frequencies being used in around your hospital, both transmitted and received? Do you know how these systems interact with each other? Comsearch can help you manage the exceedingly complicated RF environment in the hospital. Don't let your hospital be taken by the wireless storm.

  • As a technical partner with The American Society for Healthcare Engineering of the American Hospital Association (ASHE), we have developed and hosted the official frequency coordination database for Wireless Medical Telemetry Service (WMTS).
  • For over three decades, Comsearch has been helping businesses design and manage their wireless environments.
  • Our engineers have years of experience in identifying and solving a vast array of RF-related spectrum and propagation issues.
  • We have an unsurpassed depth of knowledge in RF engineering, spectrum usage and mitigation techniques.
  • We use state-of-the-art measurement equipment and techniques.
  • We can rapidly deploy engineers, as needed, to provide troubleshoot measurements to identify harmful RF interference source(s).
  • We work closely with ASHE to identify and address wireless issues in hospitals.

  • Proactive approach to avoiding interference to your wireless devices. Assess and minimize risk
  • Involve stakeholders
  • Benchmark wireless environment
  • Define where wireless devices can operate
  • Lay out a 5–10 year vision
  • Quick resolution of potentially debilitating interference to across the entire hospital

Case Studies
Here are a few interference incidents that have occurred in hospitals:

  • Walkie-talkie into defibrillator
  • FM radio into apnea monitor
  • CB radio into fetal heart beat detector
  • DTV into wireless telemetry (non-WMTS)
  • RF-surgery equipment into anesthesia monitor
  • Cellular phone into infusion pump
  • Fluorescent lights into wireless telemetry (non-WMTS)
  • Flat screen computer monitor into WMTS
