Expanding Medical Telemetry

While the inability of Wireless Medical Telemetry Service (WMTS) receivers to reject compliant signals from the immediately adjacent commercial band represented a profound risk to patient safety, it also opened up an extraordinary opportunity to expand the capacity and capability of medical telemetry systems. The fact that today’s WMTS receivers are sensitive to interference from the commercial band means that they have the ability to be software redefined to utilize commercial spectrum. Thus, when TerreStar and the medical community were unable to resolve interference concerns over Smart Grid network deployment, the company made a radical proposal to utilize the commercial resource for medical telemetry operations. In protecting life-critical networks, TerreStar would also give them the channel capacity to significantly increase the scope and sophistication of their operations.



Assessing the Clinical Impact of Interference Induced Patient Monitoring Failure

Patients monitored by medical telemetry systems have a significantly higher probability of surviving a cardiac arrest.  Making highly conservative assumptions, it is possible to begin constructing a model that estimates the negative clinical impact of WMTS interference. While there are many variables in any risk assessment, it is clear that widespread interference to WMTS networks will have unacceptable clinical consequences, including fatalities. It was this fundamental conclusion that convinced TerreStar to agree with medical industry calls for the suspension of Smart Grid network deployment.


“Hospitals should be in a position to benefit quickly from the additional capacity. TerreStar’s aggressive proposed performance milestones demonstrate its motivation to work quickly with manufacturers, hospitals and ASHE to deploy wireless monitoring devices in its spectrum. Because of the proximity of the TerreStar spectrum to existing 1.4 GHz WMTS spectrum, we understand that WMTS manufacturers may be able to modify their equipment relatively easily to access the additional spectrum.”

Using Commercial Spectrum to Significantly Expand the WMTS Resource

The deployment of commercial spectrum for medical telemetry applications promised to permanently eliminate interference while doubling the capacity of current WMTS systems.  More capacity means the ability to service more patients with significantly expanded capabilities.


“GE will be ready to deploy wireless medical telemetry systems that use TerreStar’s 1.4 GHz spectrum. We appreciate TerreStar’s interest in protecting WMTS systems from harmful interference and enhancing wireless medical telemetry capabilities in response to growing healthcare needs.”

Expanded Capacity for More Patients and Enhanced Clinical Functions 

The addition of commercial spectrum for wireless medical telemetry would significantly increase both the number of patients that can be monitored and the depth of data that clinicians can capture.  More monitored patients with richer patient data means higher rates of survivability.
