Internet comes in from fiber (full duplex up to 10gigabit possible) into a fiber converter in the hallway, then into the top white gateway in this photo.
It then gets split off into IPTV boxes in other rooms, the white phone converter (takes the ip phone signal and sends it into the old copper wiring, letting old style phones work like normal) and to the grey cable that goes into an S1300 here:
Seriously though. We have been housesitting and moving houses a lot. Rather than having to connect all our devices (probably about 12 including an Android TV box and Chromecast) to the house network every time we move I just connect them all to the GL.iNet router then WISP to the house WiFi and away we go and when we move house again, one connection and we’re away again!
Oh just remembered and the AR750s has a fancy 32GB sd-card acting as a SMB media server too and if the house has deads spots the Mango now fufils that purpose.
2 relays for door strike releases, 2 inputs for door contacts for monitoring door states, tied into internal GPIOs with a custom made cable. Thanks to MiFi LTE module these units are literally plug and play for our contract installers. We were originally using AR150s with Huawei LTE modems, but MiFi provides a cleaner more complete solution and saves a bit of cost too.
Yup, drilled 1 hole for relay connection and hole on opposite side for external 5V input from regulator board mounted below MiFi (Door strikes are 12V, so the entire system runs off a single 12V supply).
MiFi is acting as LTE gateway but also running custom software we built to allow relays to be triggered from our cloud platform and status to be shown in realtime. LAN interface is used for onsite troubleshooting in case LTE fails communication for some reason. LAN and Wireless also leave room for future potential (i.e. adding IP camera and possibly tying in other devices).
The relay board requires 5V power (also taken from the 5V rail of the MiFi since that’s a direct pass through I was told) but has transistors/driver circuit built in to be triggered by anything above about 2V. So works very well with minimal external components needed.
Most times I have to use it in WISP/Repeater mode; but sometimes I luck out (like this particular stay) and the hotel has real (and working!) Ethernet connections so I use it that way; the thruput is far better. Either way, I like to wire up my Fire Stick and laptop as the fewer active devices trying to contend for the WiFi channels the better.
