The Things Network (TTN) is a global LoRaWan public network kernel based on crowd-source infrastructure. This initiative sounds really interesting in my point of view because it breaks one of the main LoRaWan issues : the country based operators organization.
Related to this good point, the negative point is the current area covered by a such network limited to the contributor localization, generally in the main cities.
That said, I’m convinced : when you want to create a private LoRaWan network you have to manage a network kernel managing gateways, device authorizations… You can do it yourself, you can pay someone to do it for you or, eventually, you can lever TTN for this use. As a counterpart you will extend the network and offer this benefit to any around. That way it makes sense and gives large opportunities to the networks and it’s private users.
Long introduction for a technical topic … How to join this network once you have a Kerlink LoRa Iot station available ? Continue reading
Sigfox has announced end of last week the opening of the device Geo-location service. This solution allows to get the location of a device based on its radio signal.
The downlink process is the way a sensor can receive data from the network. This process is really useful if you need the device to execute an action or if you want to change the sensor behavior.
Episode 3 & 4 of my Youtube series about LPWAN is about antennas for LPWAN and impact on object design. The episode 4 go deeper on the way to improve radio performance by tuning and adapting antennas with matching circuit.
The RF 868MHz is a public bandwidth European Low Power Networks (LPWAN) as Sigfox and LoRaWan are using for communicating.
