Abstract: A field calibration verification tool for a shunt type tension meter has a central body and at least one calibration portion connected to the central body. Each calibrating portion has a tapered portion and a measuring portion. The measuring portion has a specified calibration dimension corresponding to a specific calibration value obtained in a calibration lab. The calibrating portion is inserted into a tension meter up to the measuring portion, which produces a dial reading on the tension meter, which may then be compared to the specific calibration value.

Abstract: A method of controlling a radio access network entity of a data unit communication network is described, said radio access network entity being involved in providing a transport service to a radio terminal of said data unit communication network, said transport service being characterized by a set of values associated with respective service quality parameters, said method comprising: monitoring (S30) a communication quality at the radio access level of a communication between said terminal and an access point of said radio access network, and setting (S31) a congestion indication marking in data units of said transport service if said communication quality fulfils a radio communication degradation condition.

Abstract: In a method and a device a detection mechanism enabling a cellular radio system to detect deployment of two or more radio base stations having a small coverage area close to each other and configured to use the same scrambling code is provided. The detected information can be used as a trigger to automatically reconfigure one of the radio base stations having a small coverage area.
