"Data applications are becoming more and more important in all areas mentioned so far. Low data rate applications such as [[barcode reader]]s can as well be served as advanced application like [[Internet access]]. Today, DECT products provide data links with up to 552 kbit/s. New modulation schemes will rapidly allow the rate to grow up to 2 Mbit/s."

Eventually, as with the rest of [[healthy signal infrastructure]], probably the [[DECT]] [[standard]]s are required, and friendly retail should be encouraged to move this way: By reducing the number of devices to just one, this cuts [[e-waste]]. DECT can replace the existing phone infrastructure used in the friendly retail location, and provide huge advantages for multiple location organizations: | |||
:"equally suited for data and voice services in all environments, be it for a single line with one cordless phone, or for a large-scale system with several thousand users on various sites" | |||
:"In a multi-cell system such as a cordless PBX, [[handover]] from cell to cell is fully transparent to the user." And, it cuts the carrier out of the billing loop, as, for instance, each supermarket can carry traffic from the whole area surrounding it, without ever resorting to a carrier. If a manager of one store makes a call while at another store, everything is carried over the store net - not a public carrier. | |||
:"seamless mobile communications environment serving just a few up to several thousand users on one or more sites. The DECT digital radio technology permits very high densities of users to be served, in a secure and robust way and to profit by both voice and data services with a single infrastructure" | |||
:in [[Wireless Local Loop]] (WLL) it's "a rapidly available, low-cost, high-quality radio alternative to wired subscriber local loops, to bring public network voice and data services to subscribers. It enables quick network deployment, coverage to be built up as needed, and can be used as a replacement for the wireline, thereby reducing the initial capital investment for the operator." | |||
:"DECT and [[GSM]] networks, for example, can combine with the complementary strengths of both standards, to give users full mobility with integrated [[dual-mode handset]]s." | |||
