Method and arrangement in a network control node, for performing access control of a mobile node in a handover from a source cell to a target subscriber group cell. The multi-band antenna includes a conductive patch separated from a ground plane by a dielectric material. If the network printer is adapted to print onto label media containing embedded RFID transponders, and the RFID interrogator is oriented with respect to the network printer so that a mouth of the printer is disposed within the interrogating range, the information can be written to an RFID transponder embedded in a corresponding print label of the label media. A rupture member has a first side exposed to the activation chamber and a second side exposed to the interior of a base pipe. The method further includes the steps of monitoring an output signal of the microsensor, comparing the output signal to an expected value when the microsensor is in the test mode, and determining if the microsensor is functioning properly as a function of the comparison.
