Hospitals becoming wireless hotbeds

Over the last several years, many hospitals have gone from being no-cellphone zones to wide-open wireless environments, with multiple types of wireless networks co-existing to provide anywhere communications and real-time delivery of medical testing data and telemetry. The challenge is to put in a wireless infrastructure that can evolve, providing reliable coverage but also controlling interference and managing so that wireless becomes a true safety net. Having multiple types of wireless systems at work within one building, including wireless data networks, cellular voice networks and telemetry networks, can create interference, which is what led to the early ban on cellphones in hospitals.
