In noisy, dusty production environments—factories, chemical plants, mills, etc.—in-building wireless communications canbe a convenience, a boost to productivityand, in dire situations, a life-saver. Digital Enhanced Cordless Telephony(DECT) is an ideal wireless solution forthese environments because it supports a secure, dedicated, voice-only network in an assigned frequency band. This eliminates or minimizes interference from RFID devices or scanners. DECT also requires a shortened planningcycle when compared with Wi-Fi and isconsequently more easily scalable. Handsets for production environments Avaya DECT 3740 / 3749 WirelessHandsets are specifically designed forrugged production environments. Theseshock and scratch-proof phones withback-lit keypads, large displays andenhanced liquid and dust protection aredesigned to enable users to quickly makeand receive phone calls (including CallerID), take advantage of hold, conferencingand messaging and get efficient accessto additional Avaya Aura® CommunicationManager capabilities. The built-in speakerphone, headset compatibility and text messaging simplifycommunications for workers in widely distributed production locations. Communications takes place over adedicated, encrypted wireless network.Batteries support up to 18 hours of talktime and up to 150 hours of standby time(10/80 hours on the 3749). The 3749 DECT telephone has an ATEXcertification (EMEA and US) so that it canbe used in areas where an intrinsicallysafe device is required (e.g., the chemicalindustry, mills). Built-in sensor and alarming capabilitiesmake these handsets a good choice forisolated or other high-risk work environ-ments where an employe might be working alone. They can be integratedwith building security systems. The DECT standard is widely used inEurope and was approved in the UnitedStates in 2006.
