In noisy, dusty production environments—factories, chemical plants, mills, etc.—in—building wireless communications can be a convenience, a boost to productivity and, in dire situations, a life—saver. Digital Enhanced Cordless Telephony (DECT) is an ideal wireless solution for these 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 planning cycle when compared with Wi—Fi and is consequently more easily scalable.

These handsets are specifically designed for rugged production environments. These shock and scratch—proof phones with back—lit keypads, large displays and enhanced liquid and dust protection are designed to enable users to quickly make and receive phone calls (including Caller ID), take advantage of hold, conferencing and messaging and get efficient access to additional Avaya Aura® Communication Manager capabilities. Communications takes place over a dedicated, encrypted wireless network. Batteries support up to 18 hours of talk time and up to 150 hours of standby time (10 / 90 hours on the 3745 & 3749). Wireless Handsets for Rugged Environments Avaya Wireless Handsets 3745 / 3749 avaya.com 1 The Avaya Wireless Handset 3749 is certified to ATEX (Atmospheres explosables) standard, Explosion protected and CSA (Canadian Standard Association) approved. It can be used in areas where an intrinsically safe device is required (e.g. the chemical industry, mills). Built—in sensor and alarming capabilities make these handsets a good choice for isolated or other high—risk work environments where an employee might be working alone. They can be integrated with building security systems. Enhanced security allows early encryption and re—keying during an ongoing call and also addresses the security risk of staying permanently open for registration by placing registration activation under user’s control. Secure Real—time Transport Protocol (SRTP) is available for voice encryption on an IP network. The DECT standard is widely used in Europe and was approved in the United States in 2006.
