mHealth is a component of eHealth. mHealth is a general term for the use of mobile phones and other wireless technology in medical care. To date, no standardized definition of mHealth has been established. The Global Observatory for eHealth (GOe) defined mHealth or mobile health as medical and public health practice supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants (PDAs), and other wireless devices. mHealth involves the use and capitalization on a mobile phone’s core utility of voice and short messaging service (SMS) as well as more complex functionalities and applications including general packet radio service (GPRS), third and fourth generation mobile telecommunications (3G and 4G systems), global positioning system (GPS), and Bluetooth technology. mHealth is also used for disease surveillance, treatment support, epidemic outbreak tracking and chronic disease management.

mHealth is considered of extreme importance in making healthcare more accessible. It has the potential to reduce cost and increase the quality of healthcare. mHealth can combine patient treatment and care technologies with human health control devices to influence each other. This technology thus has the potential of embedding technologies which can improve human health more efficiently.
