Defect – a Defect is a malfunction in the Software due to the Software failing to perform according to its specifications;

Effective Date – the date on which the Cloud Services are commercially accessible by Customer;

End-User License Agreement (EULA) – the underlying agreement with generic terms and conditions between TTI and Customer, of which this SLA is an exhibit;

Incident – operational occurrence in the software as a result of a Defect, that degrades the Availability and which is validated by TTI as a degradation of the Cloud Services;

Order – TTI's product ordering documentation or purchase flow as described in the EULA;

Reseller – authorized entity who resells TTI products to a Customer on TTI's behalf;

Software License – commercially available and downloadable software products, referred to as "Enterprise" or "Self-Hosted" deployments;

5. End-device and gateway requirements

SLA provisions apply to devices and gateways that meet the following requirements. The reason for these requirements is to allow Customer to apply best practices for reliable and scalable deployments. For cases that do not meet these requirements, this SLA is offered on a 'best effort' basis. TTI may decide to not treat or resolve such cases at all, in which case Customer will receive a notification.

Devices are required to:

  1. Be LoRa Alliance certified;
  2. Have a DevEUI issued from an IEEE block, from the device maker or the Customer;
  3. Be assigned DevAddrs issued by the Network Server of The Things Stack Cloud;
  4. Have not been registered on another LNS before with the same security keys;
  5. In case devices support a configurable join interval, joins must back off to at least 10 minutes after several failed attempts;
  6. In case devices support a configurable initial data rate for join-requests, they must start at least on SF9;
  7. Implement time randomised uplink messaging;
  8. Implement ADR for stationary devices.

Gateways are required to:

  1. Check for configuration (and preferably firmware) updates periodically, and be able to update their frequency plan and cluster address remotely;
  2. Detect connection loss;
  3. Reconnect automatically after losing connection, with backoff and jitter to prevent 'thundering herds'
  4. Re-resolve DNS when reconnecting.
