("Bluetooth" is a term generally designating digital wireless communication among personal-computer-associated devices i.e., "digital enhanced cordless telecommunication" between laptops, personal computers, personal digital assistants, cell phones, printers, digital cameras, etc.
Domestic sources are sources people choose to have or use (voluntary), for example a mobile phone, a cordless phone (digital enhanced cordless telecommunication (DECT)), and a microwave oven (though it is recognised that concerns about each of these domestic sources can be very different).
AR tools will enable developers to enhance cameras' functionality by displaying information like directions, adding digital objects and enhancing digital objects.
Meanwhile, the European Conference on Posts and Telecommunications (CEPT) had begun work on another personal communication system, known as DECT (Digital Enhanced Cordless Telecommunications, formerly Digital European Cordless Telephone).
DECT (Digital Enhanced Cordless Telecommunications) technology was recently approved for use in the U.S. and has better call quality and range than 2.4GHz and 5.8GHz and doesn't suffer from wireless network interference.

Other wireless phones, e.g. cordless phones of the Digital Enhanced Cordless Telecommunication (DECT) type, are also common and can be as frequently used, if not more so.

During this measurement, the participants were asked to fill in a diary recording acute symptoms at noon and in the evening before bedtime as well as the frequency of mobile phone calls and DECT phone (Digital Enhanced Cordless Phone) calls in the previous hours.
