In one embodiment, a network control module permits any or all of power signals, traffic signals and controller command signals to be carried on as few as one wire or cable to a first port of the network control module. In another aspect, a “peripheral array” includes a network control module (in any one of a number of different possible embodiments), with one or more peripheral devices, such as antennas, attached to or coupled with the network control module outputs. In one embodiment, RFID “smart shelving” may be fabricated in sections, with several (for example, 4, 8 or 16) antennas in each section, and as few as one cable coupling adjacent sections. Additional embodiments are described and claimed.
