What are the benefits of DECT over WiFi handsets?

DECT started out as a protocol for voice, whereas WIFI started for
data. It has less interference with other devices using the same
frequency.

We've noticed that our DECT sets have much longer battery life than
WiFi equivalents. John you are correct many have WiFi networks in
place already, but be cautioned - are they voice ready?

This is certainly a benefit to DECT however if there is already a
WIFI network in place the customer would typically want to leverage
it for voice without bringing up a second wireless network and a
third IP network to manage. Caution is needed for Voice on WIFI but
potentially has much broader coverage.

The WiFi network equipment will be critical to the experience and ultimate solution and this is where there is significant differences between WiFi manufactures. The typical key here is the number of VoWiFi handsets in use on an AP, roaming requirement as well as the data use at the same time and if the WiFi network has the ability to support true bi-directional QOS

I totally agree and the real issue is that there are significant
differences in how WiFi manfactures provide the increased coverage
benefiting both voice and data. Along with this is the total number
of devices for both voice and data. Hospital for example have
virtually the same coverage requirements for voice and data and
dovetailed with this is their need for location tracking. A
'Cellular' approach to the WiFi architechure, seamless handoff,
ubiquitous coverage and bandwidth management by applicaiton along
with the the ability to support bi-directional QOS for voice as
well as large number of wireless devices in concentrated locations
appears to address all the issues. A manufacture that addresses at
least these requirements allows for all three requirements to be
supported by a single infrastructure leverageing that capital
investment.
