LoRaWAN General

Q1. Frequency band for LoRaWAN in India?

-When we tried to find the official stance of India on this frequency band, we found a document published in 2005 by the Ministry of Communications and Information Technology in India designating the 865 MHz to 867 MHz as a license-free band for the use of low power equipment .

Q2. Big Endian Vs Small Endian?

• Big-endian is an order in which the "big end" (most significant value in the sequence) is stored first (at the lowest storage address). Little-endian is an order in which the "little end" (least significant value in the sequence) is stored first. For example, in a big-endian computer, the two bytes required for the hexadecimal number 4F52 would be stored as 4F52 in storage (if 4F is stored at storage address 1000, for example, 52 will be at address 1001). In a little-endian system, it would be stored as 524F (52 at address 1000, 4F at 1001).

Q3. Basic Characteristics of LoRa Modules ?

• Receive current : 11 mA ; Transmit Current : 120 (RFOP = +20 dBm, on PA_BOOST) to 20 mA (RFOP = +7 dBm, on RFO_LF/HF Pin).
• All valuable resources : https://www.semtech.com/products/wireless-rf/lora-transceivers/sx1276#download-resources
• Sensitivity : -148 dBm.
• 20 dBm - > Max Power (100 mW)
