The signal strength LED works for both GSM and GPRS modes; however the dBm reading is only
seen on the keypad in GSM mode.
Aerial Siting
ALWAYS do a site survey to find an area of strong signal before
installation. Installing a Com GSM with a weak signal is bad
installation practice.
The aerial should be mounted vertically (see below) at the point
of strongest signal. This is usually the highest point in the
building (often the loft area).
The aerial must be installed internally
Avoid installing the aerial directly under metal roofs or within
metal skinned buildings because this will reduce the signal
strength and may inhibit operation completely. If this is
unavoidable, the strongest signal will be found away from the
metal roof or close to large external windows or skylights.
Avoid installing the aerial close (2 metres) to cable runs,
ducting, structural metalwork, metal pipes, water tanks and
electronic equipment, e.g. photocopiers, fax machines etc.
These can have similar effects to metal roofs.
Reliable operation is unlikely with a low signal strength. If the
display shows that the signal strength is 40% (-88dBm) or lower,
you should improve the signal strength. This may be achieved
by repositioning the aerial. The GPRS aerial lead should not be
cut, therefore repositioning the aerial may require that the
Premier Elite Com GSM is also repositioned. The aeriel lead
may be extended by a maximum of 10 Mtrs.
The DualCom® CS2366 Radio Test Set is ideal for surveying a
site. This handheld unit can check the availability, signal
strength and interference status of all surrounding Base
Stations. In addition, it will identify the best location for a GPRS
aerial within the building, help to avoid sources of interference
and can confirm the availability of a GPRS service at the
proposed site.
Where a Nokia ‘Net Mon’ phone is available and a Vodafone
SIM Card is fitted, it may be used in the same manner as the
CS2366 Radio Test Set.
Alternatively, a Vodafone mobile phone may be used to locate
the point of strongest signal. The signal strength indicator is
normally a bar or line at the side of the display on the mobile
telephone. Note: The mobile phone MUST use the Vodafone
network. A mobile phone that uses a different radio network will
NOT show the correct signal strength.
This ‘mobile phone’ method cannot provide information on the
availability, signal strength and interference status of all radio
Base Stations in the surrounding area. Use of the CS2366 Radio
Test Set is recommended.
When you have identified the point of the strongest signal, make
a note of this point and use it when installing the
Premier Elite
Com GSM aerial.
Remember: It is always easier to find the point of strongest
signal before the equipment is fitted to a wall. Moving aerials,
cables, trunking etc. after installation is wasted time and effort.
