Limitations: data rate, packet size, 30 seconds uplink and 10 messages downlink per day Fair Access Policy

(Kalon33) #48

@arjanvanb I didn’t found that info in TTNmapper FAQ, do you know which packet rate (nb of seconds between packets, or packets/min) is authorized in SF7 (BW125) in Europe when performing mapping (and only mapping of course)? As for R&D, I imagine it’s higher than what is defined in Fair Access Policy? Because it’s hard to map with 5 minutes or so between packets with a moving node…

Thanks for your help.

For mapping and any R&D, any duty cycle regulations for one’s region would still apply as usual.

The Fair Access Policy is a daily maximum of 30 seconds. As even a zero byte application payload would be fine for mapping, you could send 647 packets in SF7, with a delay of 4.6 seconds (assuming a 1% maximum duty cycle). So, you could be mapping for almost an hour without hitting the Fair Access Policy either. Even more, it’s not enforced yet.

Same values for 1 and 2 bytes application payloads (plus the 13 bytes header)

If I set up a private network as described in your tutorial , is Fair Access Policy automatically disabled or is there a configuration parameter to do that ? Thanks


Fair Access Policy isn’t enforced yet on the public servers, nothing to disable on private networks either.

When a ‘Link Check commands’ is used, the TTN send an Downlink with empty payload.
Is this downlink is count in restriction ( 10 downlink per day ) ?
Thank for response

All downlinks count, also downlinks sent in response to requests sent by the device. This includes ACKs to confirmed uplinks and responses to MAC requests such as LinkCheck for example.
