It is rather similar like Nordic NRF24L.
The tablet transmits the bait in parallel multi-channel broadband spectra and waits the say-back from receiver a)was it received b) what was S/N ratio c) what was parity check code
One bad answer and bait is repeated "louder" and slower. Still not successful? Power is made maximal and speed minimal and it is repeated at more channels until receiver saluted "I have heared it clearly, sir!"
Slightly there is the difference between Lora and Nordic, just Lora is significantly slower, significantly less battery consuming, and about 3x...6x more far-beating than NRF. But NRF is about 6...10x cheaper and have micro-sized patch antenna at 2.4 GHz, whilst the Lora exists 433, 868, 915 MHz versions with duck-neck antenna.
Both exist as the separate tablets, but You shall economy an ENORMOUS amount of time, job and experience if buy a ready soldered item on pcb.
This receiver-transmitter complex have to be attached to Arduino (Atmel 328) or similar ARM (even Raspberry) what will programmatically serve it and feed with data. It may not be exploited without ARM. Software libraries for serviceing it is just abundant at arduino.cc
You can use direct transmission over tens of kilometers with LoRa, but the data rate will be correspondingly slow. Alternatively, you will eventually be able to use a LoRa satellite service like Lacuna’s offering in development.Yes I need to low power and long range. Some device could be placed in remote locations e.g. African farm or wilderness. Our aim is to send updated sensor data once a minute.
So, in regards to LORA am I correct in understanding there would need to be some form of gatway or existing mesh network in proximity? Are all LORA gateways connected?
How close do you need to be to a gateway?
So would the data be sent to a specific server where we can read the data from?
