Wireless communication or just wireless , when the context allows is the transfer of information between two or more points that do not use an electrical conductor as a medium by which to perform the transfer. The most common wireless technologies use radio waves. With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios , cellular telephones , personal digital assistants PDAs , and wireless networking.
While mHealth has application for industrialized nations , the field has emerged in recent years as largely an application for developing countries , stemming from the rapid rise of mobile phone penetration in low-income nations. The field, then, largely emerges as a means of providing greater access to larger segments of a population in developing countries, as well as improving the capacity of health systems in such countries to provide quality healthcare. The field broadly encompasses the use of mobile telecommunication and multimedia technologies in health care delivery. The term mHealth was coined by Robert Istepanian as use of "emerging mobile communications and network technologies for healthcare". While there are some projects that are considered solely within the field of mHealth, the linkage between mHealth and eHealth is unquestionable.
