7 WHITE PAPER DECT DENSITY
At large sites with optimal conditions and a relatively few simultaneous
users, the number of DECT units deployed can be much higher than
shown on page 6. Learn more about a large deployment of Sennheiser DW
Series headsets at a EE contact center at www.sennheiser.com/eecase.
For inspiration please see the EE case story movie which goes into detail about
the deployment process and the performance benefits of a wireless solution.
How to increase DECT density?
Typically, the number of employees increases when a company expands.
This will often lead to the use of more headsets in the office and thereby
increase the density. In many cases, this is not a problem but if the num-
ber of simultaneous users increases dramatically it may be necessary to
address the issue.
Today, it is possible to boost density in order to deploy a larger number of
DECT units at one site by making a few choices regarding the DECT devices.
Choose low power mode
This means that you choose a shorter range for each device. The employee
will not be able to use the full range, but in reality this is not a problem.
If, on rare occasions, an employee has to communicate more than 80-120
meters away from the desk then he or she simply switches to high power
mode.
Choose narrowband mode
Wideband mode (150 - 6.800 Hz) delivers a better voice quality but it also
occupies two of the available DECT channels. The number of channels
cannot be increased which makes narrowband mode (300 - 3.500 Hz) a
good option. The voice quality is still acceptable and each device only
occupies one DECT channel. Sennheiser DECT headsets can switch to
narrowband even in PC mode compared to similar products.
Close the audio connection when you are not in a call
The auto link function of the Sennheiser DECT headset automatically links
the headset with the base station when taken the headset out of the
charging cradle. Make sure that the users close the auto link when they are
not in a call by inserting the headset to the magnetic charging cradle again.
Otherwise the device will block channels in the DECT bandwidth. In this way
more capacity is available thus making it possible to deploy more units in
the same office environment.
Enjoy music via headphones
It is very convenient to use a DECT headset when listening to music but it
makes a lot of sense to switch to wired headphones instead. Otherwise the
music takes up two DECT channels on its own and limits the total number
of devices. Encourage the users only to use headsets for communication
and to enjoy music via headphones.
