Measuring procedure
The following sequence is an example of a possible measuring procedure:
Depending on the situation and aim of the measurement, a different procedure
may be used. We shall be looking here at a measurement procedure using 2 test
radio units.
Typical Sequence of a Measurement Procedure
• Mount the two test RUs on the first or second position according to the plan and
supply power using plug-in power supply or battery box.
• Activate the "Look Around Mode" on one test HA, switch to test system "T", and
begin measuring the first RU.
• Measure out the planned coverage area of the first test RU and enter the
measured values at the key points (critical areas, most distant points, overlap
zones, etc.) on the plan. If the measured values are not satisfactory, find a better
location for the test RU and re-measure the same coverage area. The measured
values entered on the plan must always also contain a reference to the location
of the measured test RUs. Only in this way can measurement series be compared
to each other and the best possible location be determined for the test RU.
• Switch over to the second RU and measure out its coverage area as described
above.
• In the overlap area of the two test RUs, a value of at least 40 should be
measurable.
• Check the connection quality at the critical points with a loopback connection.
• Once the coverage range of the two radio units has been measured out, the radio
units are repositioned. It may also make sense to measure out only part of the
coverage range and then to shift only one of the two radio units.
Tip:
If two people are involved in the measurement, it is advisable to maintain
a continuous call connection. The use of headsets allows the connection
quality to be monitored both visually and acoustically at the same time,
and also allows the personnel involved in the measurement to
communicate with one another. If a person is located at the test RU, the
optimum location for the RU in terms of connection technology can easily
be determined.
