I really love Reece Innovation Solar powered pod product developed by my friend Jose Marcelino. They’ve made a agricultural / industrial autonomous solar powered LoRaWan gateway for a really competitive price. With much more money to extend TheThingsNetwork in my city I would have used a such solution. But as this is just a hobby for me, I’m looking for really low cost solution, something under 500€ per gateway.
My main issue to extend the network is not really to find roof but to find some where I can pass an Ethernet cable and provide the power from it. I have some place where I could deploy new gateway in conduction to be cable-less. The network is not the main issue as most of the time a WiFi network is accessible. Powering is a larger problem to solve. Advantages of outdoor gateway: you have sun available. So, as Reece Innovation did, I decided to make my solar gateway, the main differences are: my will have no LTE communication capability (only WiFi) and it have to cost as less as possible.
Let see what I’ve done
I’ve been talking about this ultra low cost LoRaWan gateway in last October and ordered one. The time to get it has been long as it has been arrived in February this year. This sounds due to an early ordering as the product is now available, even on Amazon for a price under 180€.
This price is not so low if you compare to a Laird Sentrius but we are not talking the same product ! Here we have an outdoor gateway with PoE powering. That’s really interesting. The only missing thing is a LTE communication.
This gateway exists in two different version LoRa8 for 868Mhz zones and LoRa9 for 902 MHz zone.
Let’s see it in detail and find how to configure it for joining TTN.
The Things Indoor Gateway (TTIG) has been announced and distributed during the TheThings conference 2019. Since it was impossible to get some, victim of its success (and the little initial stock). From mid-august it is now possible to get some and I’ve bought one as soon as possible.
The Things Indoor Gateway is a low cost (70€ – 90€), 8 channels (EU868 full gateway), LoRaWan gateway running on TheThingsNetwork. You can’t expect a large coverage with a such solution to be used for city wide network but it will be perfect for covering a large house or a small building where you want to deploy LoRaWan sensors.
The Laird Sentrius LoRaWan gateway is a low cost, stable and easy to configure on The Things Network gateway. They are indoor gateway. I want to install it outdoor to offer a better coverage.
In certain situation the easiest way to install it outdoor is to use an external antenna and a long antenna cable. In some other situation this approach is complex to implement and the easiest way is to install the gateway outdoor with its antenna and network connection.
The best is to use an outdoor LoRaWan gateway. The price is usually > 600€. Even if in general the outdoor gateways includes GPS and Cellphone connectivity. In this post I’ll explain how I make one of Laird Sentrius outdoor because it costs less than 250€ for the gateway itself.
The Sigfox Micro basestation has been announced during the last Sigfox Connect event in Berlin. The base-station allow to extend the Sigfox public network, at low price, for your private location.
This post is detailing my experience with the micro base-station and the field test I’ve made on an industrial site.
