How it works
The radio is connected to the antenna array by a four way splitter. Since this divides the power from the radio by four, we added a 250 mW amplifier to the radio to compensate.
The four directional antennas giver better coverage than the previous single, omni antenna, and since the amplifier is bidirectional (i.e. it amplifes incoming as well as outgoing signals) we pick up coverage there, too.
The system increased the efficiency of the packers by relieving them of the task of manually recording their work, and eliminated the supervisor's time to tally the time sheets. In addition, they now have historical data that they can analyze.
This radio does a wireless hop back to another access point connected to their LAN.
The final installation:
Conclusion
The sectorized antenna is a great solution for outdoor coverage, especially considering the expense of installing access points outdoors.
