The PoE product includes two units: an Injector and a Splitter. An Injector inserts current into the unused wires in a standard network cable (pins: 4, 5, 7 and 8) allowing the cable between the Injector and the Splitter to transfer power and network signals simultaneously. The maximum distance between the Injector and Splitter can reach 100m/328ft, as defined by the IEEE 802.3 standard.(See the Solution Options.)

By eliminating the need for power cords, PoE has following benefits:

• Cost saving

The cost of deploying PoE is much lower than a traditional electrical circuit.

• Ease of network planning

The system designer has more flexibility to locate network devices. Independence from power outlets makes it easier to relocate devices or obtain the best performance, e,g: fine-tuning the RF coverage of an AP.

• Steady Wireless LAN connectivity

PoE allows a Wireless Access Point to be placed close to the antenna, thus avoiding signal loss over antenna cable.
