LTE networking: extending the reach for sensors in mHealth applications

Sensor and electronic-health networks are widely utilized at home and in industry/research applications. In a local sense, a sensor-to-sensor network can have a range of a few meters to a couple of hundred meters (ZigBee Pro can extend this range up to 2000 m). With the deployment of mobile technology in the healthcare space (mobile-Health 'm-Health') and using cellular coverage, the range can virtually be unbounded. However, supporting bounded delay (end-to-end delay), class of service, and quality of service for critical sensor-mHealth applications may become challenging. This challenge can be alarmingly extended when thousands of users run their sensor-mHealth applications simultaneously and depend on limited coverage of the cell tower to transmit their health-related data across. In this paper we will discuss how the 3rd Generation Partnership Project-Long Term Evolution networks can address such aggregation issues, and discuss the challenges and provide recommendations.
