	Cordless Telephones
		Cordless phones and their base stations have output powers much too low for exposures to exceed internationally accepted guidelines and HPA does not consider there are particular safety issues with their use.
		Cordless phones are held to the head like mobile phones and some of the radio waves they produce are incident on the head.
		In summary, the technical standards for cordless phones and their base stations indicate that they have output powers much too low for people's exposures to exceed internationally accepted exposure guidelines and HPA does not consider there are particular problems with their safety.

	On the ETSI's radar - What's cooking? - DECT (Site not responding. Last check: 2007-10-31)
		DECT (Digital Enhanced Cordless Telecommunications) is a high capacity digital radio access technology for cordless communications in residential, business and public environments.
		For network operators DECT is also a cost-effective and flexible alternative to conventional cable/fibre connections into customers' premises, by providing "Wireless Local Loop".
		All DECT systems are based on a main standard that is the Common Interface (CI), which is often used in association with the Generic Access Profile (GAP).

		DECT covers wireless PBXs, telepoint, residential cordless telephones, wireless access to the public switched telephone network, Closed User Groups (CUGs), Local Area Networks, and wireless local loop.
		DECT defines only the radio connection between two points and can be used for remote access to public and private networks.
		The DECT Common Interface radio standard is a multicarrier time division multiple access, time division duplex (MC-TDMA-TDD) radio transmission technique using ten radio frequency channels from 1880 to 1930 MHz, each divided into 24 time slots of 10ms, and twelve full-duplex accesses per carrier, for a total of 120 possible combinations.

	Digital Enhanced Cordless Telecommunications - Wikipedia, the free encyclopedia
		DECT is recognised by the ITU as fullfilling the IMT-2000 requirements and thus qualifies as a 3G system, as a part of the IMT-2000 group of technologies, DECT is also referred to as IMT-FT (Frequency Time).
		DECT GAP is an interoperability profile for DECT.
		For this reason, a suite of DECT handsets is generally purchased together, for instance a base station with three handsets.

	European Cordless Technology Coming to U.S. - 6/1/2006 - Wireless Week - CA6339281 (Site not responding. Last check: 2007-10-31)
		The European cordless telephone system known as DECT, or Digital Enhanced Cordless Telecommunications, is headed to the United States, aiming to provide voice services for PBX systems in small- to medium-sized enterprises.
		DECT (the "E" used to stand for European) is a cellular telecommunications system but with small cell sizes with a radius of 300 feet or less.
		One significant difference between Europe's DECT and what will become available in the United States is in Europe, the system runs in 20 MHz of spectrum (1880-1900 MHz), which is double the size of the United States' allocation.

	The Ultimate Digital Enhanced Cordless Telecommunications Dog Breeds Information Guide and Reference
		DECT or Digital Enhanced (former European) Cordless Telecommunications is an ETSI standard for digital portable phones, commonly used for domestic or corporate use.
		A major difference between the systems is the cell radius — DECT cells have a radius of 25 to 100 meters, while GSM cells are 2 to 10 km.
		In this case, a DECT radio link replaces the normally wired connection between the final PSTN distribution point to the subscriber.

		DECT carriers have been defined for the whole spectrum range 1880 MHz to 1980 MHz and 2010 MHz to 2025 MHz in the ETSI standard.
		Additionally the DECT portable continuously analyses the signals to ensure that the signals originate from the base station to which it is connected and has access rights.
		Although DECT has been in use for a number of years now, its flexibility and performance have meant that it is still the major technology used for cordless phones.

	Wireless Networking & Technology, Wireless Communication, Broadband Wireless.
		The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g., radio transmitters and receivers, remote controls, computer networks, network terminals, etc.) which use some form of energy (radio frequency, infrared light, laser light, visible light, acoustic energy, etc.) to transfer information without the use of wires.
		The term "wireless" should not be confused with the term "cordless", which is generally used to refer to powered devices that are able to operate from a portable power source without any cable or cord to limit the mobility of the cordless device through a connection to the mains power supply.
		It is interesting to note that some cordless devices, such as cordless telephones, are also wireless in the sense that information is transferred from the cordless telephone to the telephone's base unit via some type of wireless communications link.

	Define DECT - Digital Enhanced Cordless Telecommunications (Site not responding. Last check: 2007-10-31)
		Meaning of DECT — “Digital Enhanced Cordless Telecommunications”, is a flexible digital radio access standard for cordless communications in residential, corporate and public environments.
		A DECT system is based on a network of low-power radio base stations, and provides coverage throughout a premise, indoor or out.
		Whereas GSM is optimized for mobile travel over large areas, DECT is designed especially for a smaller area with a large number of users, such as in cities and corporate complexes.

	Art Digital Design: cordless telephone portable phones downloads
		Cordless telephone- A cordless telephone or portable telephone is a telephone with a wireless handset which communicates with a base station connected to a fixed telephone landline (POTS) via radio waves and can only be operated close to (typically less than 100 metres of) its base station, such as in and around the house.
		The cordless handset is powered by a battery which is recharged by the base station when the handset is connected to the base station when not in use.
		Digital cellphone systems are also offered in the PCS band, which is radio spectrum that was auctioned off by the U.S. government in the mid-1990s.

		David P. over at Boing Boing discovered that the benefits of DECT's (Digital Enhanced Cordless Telecommunications) 1.9 GHz extends to baby monitors as well, when he found that all standard baby monitors use either the 900 MHz or the 2.4 GHz range for communications.
		DECT seems to be all the rage these days whenever someone wants to make a cordless handset or headset, and Thompson isn't one to miss out on the boat.
		The next step is to roboticize this machine (which has already been done with a cordless lawnmower but not very well) like a roomba, and then you won't have to cut the grass ever again.
