Ambulances need flexible mobile connectivity that can stand up to physical abuse, high and low temperatures, and physical contaminants, all while still performing flawlessly. With 3G/4G/LTE, emergency vehicles can use the in-vehicle connectivity to power mission-critical applications, not only for accessing patient records, but also for diagnosing and monitoring patients in the field. The demands for high-availability in these applications are not only mission-critical but are also life-dependent in most cases.
