Telemedicine is becoming another natural area of applying M2M and IoT solutions. Remote diagnostics and monitoring of patients enable to reduce the costs of health care system through proactive prophylaxis and rehabilitation supervised in an automatic way. By applying new technologies, it is possible to collect data from remote diagnostic devices installed at patient’s home (e.g. regular measurement of blood pressure, weight, glucose level etc.) or use mobile devices as an alternative to doctor’s appointments. Some people may find it surprising that these systems are also used to monitor health and condition of pets, for example, special leads for cats and dogs.
