Abstract

A wireless communication network (222) transmits (232) operation enabling and/or inhibiting information to a wireless communication unit (100, 210). In response to the information, a processor (108) of the wireless communication unit (100, 210) selectively enables or inhibits transmission and/or reception of wireless signals to and/or from the at least one wireless communication unit (100, 210) in a frequency band selected from a plurality of selectable multi-band frequencies or a signal format selected from a plurality of selectable multi-formatted signal types. This provides the advantage that an operation of a communication unit with respect to frequency bands or signal formats can be configured and re-configured, even after the communication unit has been sold to an end user. Such a reconfiguration can be at the request of the end user, or alternatively can be performed independently by the network operator or manufacturer of the communication unit.
