1. A signaling arrangement for use in a wireless local area network, comprising:
- a) a scanner for electro-optically scanning indicia to be read, and for generating an indicia signal indicative of the indicia, the scanner having a wireless, radio frequency transmitter;
b) a system manager having a radio frequency receiver in wireless communication with the transmitter of the scanner for receiving the indicia signal transmitted by the transmitter, for processing the indicia signal, and for generating an acknowledgment signal indicative that the indicia signal has been processed, the system manager having a wireless, radio frequency transmitter; and
c) an indicator having a radio frequency receiver in wireless communication with the transmitter of the system manager for receiving the acknowledgment signal, and for generating an alert signal noticeable to a user upon receipt of the acknowledgment signal.
