Avaya announced a new set of IP-based wireless devices last week for businesses workers who want to be mobile within a work campus but also who want to remain connected to their voice and data network. The devices give users a choice of either voice-over-wireless-LAN (VoWLAN) or Digital Enhanced Cordless Technology (DECT) handset models.

The Avaya 3641 and 3645 VoWLAN handsets are specifically designed for industrial environments and offer “protection from dust, water or random impact” according to Avaya’s statement. The handsets support the 802.11 ‘a’ frequency, adding to Avaya’s standard ‘b’ and ‘g’ support which, according to the company “enhances voice quality through reduced wireless interference.” The new Avaya 3631 VoWLAN handset is designed for traditional offices that want a “sophisticated, yet low-cost solution” according to Avaya.

The Avaya 3711 IP Digital Enhanced Cordless Technology (DECT) Handset was designed by Avaya as a voice-optimized option to Wi-Fi. Avaya concludes that “DECT handsets are ideal for businesses that do not want to co-mingle voice and data on the same wireless network.”

Avaya’s new VoWLAN wireless devices are now available globally and while the IP DECT handset is currently only available in Europe and the Middle East, it is scheduled for release in North America next month.

Our analysis: While IP and DECT handsets are nothing new we believe “the more the merrier” when it comes to the competitive handset market. We also believe developing IP wireless devices to specific niche-markets (like an industrial setting) expands the VoIP environment in general and makes sense as IP communications are extended into increasingly diverse work environments.
