Great to be a part of this wonderful group and people and iam getting to see many things in this group with like minded around. I am a Project Manager working for an LoRa based solution deployment for one of my projects.
I have some queries and hereby requesting for your valuable suggestions.
We are setting up lora network in India with Frequency band and following are facts below:
The setup is arranged such that base station/gateway would support 5000 devices over a 9km range.
(Here we are planning for one base station fixed with clear LoS. I assume that LoS is crucial aspect for considering number of base station for 5000 end devices. Please suggest?)
Nodes are class A devices with 12 uplink messages/device/day (10 bytes per uplink msg) and 1 download message/device/day.
(Here i have a couple of doubts,
- if my consideration of 1 Downlink msg/device/day is valid, then also I hear that for class A for every uplink message there is a downlink ACKs required. So is my consideration for downlink messages number right for my 13 uplink msgs/device/day? Please suggest.
- Is TTN fair access policy limits and duty cycle dependent of region/frequency band?)
- I understand that in LoRa there is no such solution for FOTA for all devices at once.
(Here i have a doubt if individual firmware upgrading is viable for these 5000 number of devices or any such alternate approaches proven. Also if anyone in their previous experiences have performed FOTA under their LoRa setup, then for what all aspects is firmware upgrading done?)
Looking for your suggestions.
