Wi-Fi on a light pole, 300 m from the IDF

On a golf course there is no building to put a switch in. A hardened cabinet on posts is the IDF; a GL-4xTH-RPF beside it reaches a cart-path light pole 300 m away over one Cat6 pair, with a DC cable alongside.

   The course

   A light pole on the cart path by the green, and nothing else for 300 m. The only infrastructure on this side of the course is an outdoor cabinet on two posts at the tree line, fed by a utility circuit and a fiber strand from the clubhouse. That cabinet is the IDF.

   The outdoor IDF

   A sealed steel cabinet with a louvered door, bolted to galvanized posts over a concrete pad. Inside there is no rack: a DIN rail with a breaker and surge protection, a terminal block, and a small outdoor DC power supply. Conduits come up through the floor of the cabinet.

   Two small power supplies

   An IP67 aluminium power supply on the back panel takes the utility AC from the breaker and puts out 48 V DC. Its output goes straight onto the outdoor DC cable that leaves the cabinet for the pole. Beside it, a 90 W IPC-PS-90 USB-C power supply on a GFCI receptacle powers the host on the post outside.

   Meet the GL-4xTH-RPF

   A sealed IP67 ReadyLink host mounted on the cabinet's post, where a rack switch could never live. Four ReadyLink copper tails, two 10G SFP+ fiber uplinks, and no fan. It takes its power over USB-C from the IPC-PS-90 in the IDF. The first tail is spliced to an outdoor Cat6 for the pole; three tails are spare for the next poles.

   300 m to the pole

   The DC cable and the Cat6 share one conduit in the grass beside the cart path for 300 m, come up through the pole's base and run inside the pole to the box. One pair of the Cat6 carries ReadyLink between the host and the client; at 48 V the DC cable drops only about 3 V on 12 AWG over the run. Nothing runs down the outside of the pole.

   IPC-4STP in the pole box

   A 3 × 2.2 × 1.4 inch ReadyLink client in a weatherproof box on the pole. The DC cable lands on pins 1 and 2 of its 6-pin terminal (12 to 48 V DC local power), the Cat6 pair on the PT1 pins beside them. It is provisioned and monitored from the host in ReadyView.

7. 7

   GE1 PoE+ to the Wi-Fi AP

   A short outdoor Cat6 from GE1 goes back into the pole and up to the access point near the top. The client powers the AP with PoE+ over the same cable that carries its traffic, so the pole needs no outlet and no injector. Coverage lands on the green and the tee.
