LoRa Network Server

When asking what is LoRa, you may get several different answer. One thinks it's  essentially the LoRa modulation, giving the extraordinary radio performance. Other one says it's the LoRaWAN protocol, as that is the only well specified part of the system. Third one may consider it's all about the Network Server where all the network management functionality is implemented.

In LoRa networks, especially when considering public network approach, the Network Server plays central role. Gateway is intended to be a simple packet forwarder and thus being inexpensive part of the system. At the moment there are three network server providers:
Actility is perhaps the leading supplier with most commercial deployments in place at the moment. Espotel recently joined Actility's certification program in order to ensure end-devices are compatible with the ThinkPark back-end.

LoRaWAN certification acknowledged by the LoRa Alliance guarantees interoperability of end-devices with any gateway manufacturer. However, LoRa Alliance  does not specify the interface towards Network Server, thus it is implementation specific. That's why different back-end providers may have their own certification programs, like Actility does.

The test network is very easy to set up. The supplied gateway is pre-configured to ThingPark and requires no user configuration at deployment, just blug & play. Power-over-Ethernet with provided power injector makes cable installation easy. Only internet connectivity is required. There also exists variant with cellular data modem instead of Ethernet.

Edit 2015-8-26:
According to the feedback I have received, there are several other Network service providers emerged, including Lace, Loriot, Senetco, and The Things Network. I consider that as positive sign, meaning there are many parties who believe in LoRa technology. The ecosystem is stronger all the time.
