Anyone has experience with deploying WiFi sensors with a mobile 4G/LTE modem? Basically I need the agents to be able to connect back to the server without a network infrastructure. I was thinking of using a 4G/LTE modem with Ethernet handoff. The modem should have global coverage, in particular I have a need for a deployment in Singapore. Thank you
Hi Stefano,
I recently got this information from one of our customers regarding mobile connectivity:
we’ve used 5G hotspots as a way to tell if the sensor is online or not by making use of the Ethernet port.
Typically, we aim to use direct patching to a managed network switch; however, that’s not always possible, so ad hoc technology could be considered.
I have used a few varieties of non-permanent infrastructure:
- Starlink Mini I used an Ethernet sensor as a remote monitor since a Starlink was being used as a live internet feed for a small broadcast network.
- Netgear Nighthawk M6 I have a pair of these and was able to use it on an outdoor sensor in a tricky spot at an event. It has Ethernet, so plugging in the wireless sensor was easy.
- Peplink BR1 Micro + eSIM plan This is pending testing - the router hardware is on order, but we use several Peplink products which allows us to utilize the eSIM subscription. This allows us to centrally and easily manage the cellular routers compared to the Nighthawk M6. We’ve used Cradlepoint products in the past, but the account management & UI aren’t as intuitive and streamlined as the Peplink iControl cloud ecosystem.
The last consideration in context to our mixed indoor/outdoor environments where we would make use of a cellular connection, it may be tricky getting power outlets. You’ll need 2x outlets total: one for the modem and one for a POE injector or USB connection (depending on which sensor model you’re using). If outdoors, house everything in some kind of NEMA box that’s plastic ideally.
I hope this helps!
