The company provides support for Linux through Yocto Project or Buildroot and Debian and OpenWrt images can be provided. You will find additional information about the hardware and more details about the software at website for developers. Because the gateway supports Wirepas Massive, you may want to check the relevant section of the documentation.
But what exactly is Wirepas Massive? The explains the company (Wirepas) in a post titled “Best IoT Network”:
Our software provides wireless technology for corporate IoT. Battery-powered and built into your devices, it enables scalable, reliable and cost-effective IoT solutions. Connect billions of devices as dense as you want. On a standard ready-made radio with a frequency of 2.4 GHz.
Our software has no limits. Each device becomes completely autonomous to create a self-organizing and self-healing network. It can’t fail. You can try doing the same with Zigbee, Thread or Bluetooth Low Energy (BLE) Mesh, but it just won’t work. No other technology gives you that.
The Wirepas Network offers a horizontal connection layer for all IoT applications: collect data from your IoT cloud sensors, monitor remote devices, communicate device to device on a network with or without a cloud, and track the location of moving assets. All network intelligence is included in the Wirepas software to form a sustainable large-scale wireless network.
In principle, this is a network networking solution running on 2.4 GHz radio stations and designed for large-scale corporate IoT networks with up to 4 billion devices in one network. In fact, the company says customers have more than 100,000 devices installed on a network. Smart cities come to mind as an application.
The Finnish company also claims that battery-powered routers can run for more than 5 years with a 4000 mAh battery transmitting 1.5 packets per second, which is plausible because the gateway may not work as much on a network. … The technology used should be called Wirepas Mesh, but I guess the marketing team didn’t want to be outdone 5G “Massive IoT”, so it was changed to Wirepas Massive.
Only at that time two models are available for pre-order, one without Wirepas support for $ 221 and another with Wirepas for $ 231. More details about the SolidSense N8 Compact IoT gateway can be found at the SolidRun website.
