Measuring the cell of a base station

¤ Temporarily secure the measuring base station in the position in which the base sta-

tion is to be installed.

¤ Establish a telephone connection between the two measuring handsets or activate

the continuous test tone of the measuring base station (

£ page 38).

¤ Move away from the base station with the handset, observing the display and the sig-

nal in the earpiece, until the limit value of –65 dBm is displayed or a wireless transmis-

sion boundary is reached (e.g., lift, exterior wall). Transfer this point to your plan and

enter the value in the measurement log.

¤ Use this method to determine the border line around the base station. The theoretical

ideal case of a ring-shaped transmission is considerably altered in reality by walls

(depending on the construction material) and metal furnishings.

¤ Check the voice quality in the limit areas using the connection to the second measur-

ing handset or the measuring tone of the base station.

¤ Enter deviations in the reception signal measurement of the voice quality in the layout

plan or the measurement log.
