The DEFINITY Wireless Business System (DECT Release 2) connects to the sys-
tem as adjunct devices, thus providing flexibility in setting up applications. It uses
an international industry standard that is more common in some parts of the
world.
This system features Lucent’s Wireless System Engineering Expert Design Sys-
tem. This patented software, which is unique in the wireless industry, analyzes the
building or campus space and determines how the wireless system should be
configured. It precisely recommends where the base stations should be located
within the structure or structures. The software effectively eliminates the most dif-
ficult aspect of wireless implementation and ensures maximum efficiency and
lower life cycle costs.
DEFINITY Wireless Business System
The DEFINITY Wireless Business System (international only) uses the latest
Digital Enhanced Cordless Telecommunications (DECT Release 2) technology —
the leading European standard adopted in over 70 countries worldwide. It
operates in the allocated 1880-1900 MHz spectrum. Since this is an unlicensed
frequency range, there is no charge for air time when operating in this band.
