Aastra Introduces DECT CAT-iq to Business HD Voice

Contributing Editor

CAT-iq has been around for a while, but it is still a pleasant event to see it arriving on the corporate desktop. Aastra says it is the first vendor to offer HD voice to "corridor warriors" with its SIP-DECT 3.1 release.

Aastra says the SIP-DECT release 3.1 gives it a series of industry firsts including, the first enterprise DECT handset with CAT-iq certification to offer HD quality audio (well, if you're CAT-iq 1.0 certified, you have to have G.722), the first to offer a DECT network with a Gigabit Ethernet (GigE) backbone, the first to offer a comprehensive CAT-iq solution for business DECT, and the only company with a DECT/WLAN standard combo base station.

Included with the new release/launch of SIP-DECT 3.1 are the Aastra 650c DECT phone Aastra's DECT base stations, including the RFP 35 IP for indoor use, a "combo" RFP 43 WLAN , the RFP 36 IP with built-in antenna s for outdoor use, and the RFP 37 IP for use with external antennas for outdoor communications. All of the new base stations fully support CAT-iq and Gigabit Ethernet.

Aastra's SIP-DECT 3.1 can be integrated with Aastra's communications servers, SIP compatible call mangers, IP Centrix or Microsoft Lync with certified gateways.

Operating on a reserved and regulated piece of spectrum, DECT delivers a RF disciplined, managed solution for cordless handsets. It's a much better experience and more reliable than the potential hit-or-miss experience using 2.4 GHz Wi-Fi-based phones when someone turns on a microwave oven. I prefer to have DECT phones over Wi-Fi because of the typically longer range of a DECT from its base station and to keep 2.4 GHz and 5 GHz bands open for data use.

DECT phones have been a niche offering in the enterprise, with the technology more commonly appearing in residential and small office/home office handsets. However, the DECT forum has a technology roadmap to extend use of the wireless standard to ultra low energy (ULE) applications for battery-powered consumer devices such as alarm systems and security cameras.  

For enterprise applications, DSP Group executives have discussed the potential for scaling DECT ULE from a couple hundred nodes (devices) up to more than 2,000 devices to support applications such as enterprise automation and various machine-to-machine (M2M) processes.   DECT can provide data rates of up to one Mbps, giving it the capability to easily support low volume data transactions all the way up to video.
