Preventive maintenance

Maintenance of the radio includes measurements which do not interfere with the
communication. Measurements which do interfere with the communication can
also be conducted when the radio is in operation, provided that the measurements
are performed at a time when there is no traffic or the traffic can be rerouted. With
the Nokia Network Management System (NMS), service measurements can be
performed in a centralised manner for the entire network without having to move
physically from station to station. However, any measurements performed with
external measuring instruments must be conducted locally.
Record the measurements so that they can be compared with earlier results and
used to detect significant changes in the results. Store the measurement records at
the location where the measurements are conducted, that is, the records of
centralised measurements in the central monitoring room, and the records of
external measurements at the equipment station.
