Wireless Medical Telemetry Systems (WMTS)
Consulting and Troubleshooting
Growing concerns about interference resulting from new digital television transmitters and greater use of Private Land Mobile Radio equipment makes it critical that a proper Wireless Medical Telemetry Service WMTS RF Spectrum Analysis sweep is performed for each installation. Connect802's predictive RF CAD modeling design can create WMTS installation plans based on hospital blueprints.
The American Society for Healthcare Engineering (ASHE) provides frequency coordination services in the WMTS radio bands. Once you've obtained your coordination certificate it's time to design the receiver antenna infrastructure for the WMTS system in the hospital. That's where Connect802 Corporation comes in...

like Draeger Medical have developed
telemetry devices based on industry-standard
Wi-Fi. For example, Draeger's "Infinity
Telesmart System" provides a view
of all monitored ECG leads, heart
rate and pulse oximetry while at
the patients side (see picture on
this page's top banner) while passing
alarms and alerts to a central monitoring
station. Of course, any medical telemetry
based on a Wi-Fi wireless network
demands that the in-building wireless
LAN provide full, consistent coverage
and capacity. Connect802 can help
with today's most sophisticated Wi-Fi
telemetry systems by dispatching
an engineer to perform a coverage
validation survey confirming that
the wireless LAN will support proposed
or existing Wi-Fi medical telemetry
equipment. Connect802 can also design,
install Wi-Fi wireless LAN equipment
to remediate any coverage gaps discovered.
Wireless Medical Telemetry Service (WMTS)
The Federal Communications Commission (FCC) defines wireless medical telemetry service telecommunications in 47 CFR 95.1103(c): "The measurement and recording of physiological parameters and other patient-related information via radiated bi-directional electromagnetic signals."
Equipment operates in the UHF television frequency range on unused Channels 7-12 (174-216 MHz) and 14-16 (470-668 MHz). Three licensed operating bands are specified in FCC 95.630: 608-614 MHz, 1395-1400 MHz, 1427-1434 Mhz. WMTS medical telemetry is licensed for use only in a healthcare facility by authorized healthcare providers (i.e. no home or vehicle/ambulance use).

WMTS RF Spectrum Analysis Consulting and Troubleshooting
Connect802's broad scope of RF spectrum analysis experience and expertise is ideally suited to the task of on-site analysis, consulting, design and troubleshooting for Wireless Medical Telemetry Service WMTS systems and Medical Implant Communications Service (MICS) systems. Our engineers have a deep understanding of the technology. They also understand the human element: greater patient mobility and comfort as well as increased healthcare worker efficiency. Our engineering teams have worked in the largest hospital facilities as well as the most rural community medical centers. We understand how to get the job done with a minimum of disruption to patients, doctors, nurses and staff.

Wireless Medical Telemetry Service Communication Problems
Monitoring consoles report "squelch" events when transmissions from patient transmitters are disrupted. We have found two significant issues that regularly cause problems with WMTS systems. In the first case, a careful assessment of the quality of UHF television or 802.22 WRAN transmissions is required. High-power, licensed broadcasters in the community may have equipment that's bleeding over into the WMTS channel space. The second common issue relates to environmental noise most typically associated with fluorescent light fixtures in close proximity to WMTS antennas on the ceiling. Connect802 uses RF spectrum analysis equipment as well as EMI (Electromagnetic Interference) monitoring tools to track down the issues.

Nationwide Wireless Medical Telemetry Service (WMTS) Consulting
Connect802 is one of the only independent consulting companies that offers consulting and RF spectrum analysis services Wireless Medical Telemetry Service systems and has the experience and expertise to know how in-building Wi-Fi wireless networks, Bluetooth headsets and cordless phones, and other noise and interference sources interact with the WMTS equipment. That's because Connect802 is also a nationwide 802.11 Wi-Fi wireless network integrator, providing Wi-Fi design and consulting services. We're also experts when it comes to 802.16 WiMAX and the emerging 802.22 WRAN (which operates in the UHF frequency range along with WMTS).

WMTS Frequencies in the UHF Television Broadcast Range Because WMTS operates in the same frequency range as broadcast UHF television and the emerging
802.22 Wireless Regional Area Network (WRAN) standards it's critical that a professional RF spectrum sweep
be performed both before and after installation as well as when problems arise.
