Once SPN (Small Private Network) firmware installed, it forms a data collector over a LoRa network.

The classical communication case is that LoRa end-devices (also called motes or end-point devices) emit frames and open short reception windows after the emission.

• The gateway listens to the emitted frames and records those coming from authenticated end-devices.
• The gateway may acknowledge or send a frame carrying a payload during one of the end-device's reception windows.
• The gateway records information associated with frame reception: timestamp, radiofrequency data (band frequency, SNR, etc…).

The SPN station can be connected to an IP network over:

• Ethernet.
• Wi-Fi.
• GSM.

The connection to the IP network is used to:

• Get received data.
• Push data to be transmitted.
• Manage the fleet.
• Configure the gateway.
• Update the gateway.
• Get the logs.

These features are accessible through the following services:

• Web interface (HTTPS).
• Local FTP server.
• Remote SFTP access.
• HTTPS REST API.
• SMS.
• USB flash drive.
• Node-RED

Detailed instructions about SPN web interface are available on the resources page.
