We are taking over a new warehouse in the next few months. The business has a requirement for total Wireless Coverage on the Warehouse shop floor for use by stock pickers (with mobile devices). The key challenge I see here is the fact that the racking will block/reflect the RF signal. This can be addressed by using many many APs with directional antennae. I was wondering if anyone out there has any other tips for deploying a WLAN in a warehouse environment.
