LoRaWAN duty cycle abuse

@JTAG

Putting a wideband “high” power signal with a bandwidth and frequency matching an application (like gps / gsm / FM radio / wifi ) will block that application. Receiver blocking by an in-band interferer is a problem for 95% of every wireless link on the world.

Quite right, but that waht I’m talking about isn’t just trivial jamming.

a TTN gateway, backer edition.

I’m thinking about getting ten units. Street lights are Class C nodes, with ten transmitters I most probably can legally block their RX2 Oh, I even don’t need GWs, ten half-Watt modules are enough…

The real problem is that no one is actually obliged to follow LoRaWAN spec (or TTN fair access policy).

Neither LoRaWAN nor TTN fair-use policy has any teeth here. They are both advisory. But the regional regulations about ISM band use are controlled, either by duty cycle or AFA/LBT. If someone breaks those rules then it is illegal and they are open to prosecution.
Like CE marking, its a complaint-driven process. If you complain enough, the local regulator should take action.

Start with googling for “lora preamble selectivity”, my dear electrical engineer and hobbyist. At the momement, LoRa seems to be double Dutch for you Meditate, and you’ll reach you’ll reach enlightenment.
