When it comes to IoT connectivity is usually a vital component & so we can offer experience in the following connectivity methods:
Which to choose?
Each has it's strengths a weakness but they can basically be broken down into range & bandwidth:
WiFi is typically implemented by either USB dongles or onboard (e.g. Raspberry Pi).
Mobile (or cellular) requires modules that are widely available.
LoRaWAN is now available as a single chip solution. It can be an ideal communication solution for IoT projects that require low power consumption. LoRaWAN can be a stand-alone solution or can be paired to a gateway & a network backbone to facilitate internet connectivity. The Things Network is a community based gateway service allowing to facilitate such connectivity.
We established a RAK7243 gateway service in Feb 2020 & can attest to its scope & reliability. It's approaching a hundred thousand packets received & going strong!
