Abstract:
1. A bar code reading terminal comprising: a bar code reader unit; a manual trigger; a hand held housing encapsulating at least one component of said bar code reading terminal, said housing being configured so that a user can actuate said manual trigger when grasping said housing, said bar code reading terminal being configured so that when said manual trigger is actuated said bar code reader unit produces a decoded bar code data message; a radio transceiver encapsulated by said hand held housing and having a maximum output power and an operating power; wherein said radio transceiver is operative in a 2.4 GHz spectrum of an Industrial, Scientific, and Medical (ISM) band; wherein said radio transceiver is further operative to hop across a plurality of frequency channels in said 2.4 GHz spectrum when said bar code reading terminal is in a connected state so as to reduce interference with other devices operating in said 2.4 GHz spectrum; and wherein said operating power of said radio transceiver is limitable to a power limit that is less than or equal to said maximum output power of said radio transceiver and is operator selectable from a set of power limit values including said maximum output power and a plurality of additional values, so as to reduce interference with other devices operating in said 2.4 GHz spectrum.
