Being an early adopter and member of the LoRa Alliance since 2016 KELLER has a lot experience with LoRa.
LoRaWAN™: Long Range Wide Area Network, is a protocol developed by the LoRa Alliance.
The peculiarity of this new protocol is the efficiency; because LoRaWAN™ has the minimal power consumption, long range of communication (up to 15km in rural areas) and secure data transmission (with AES-128 encryption).
The range of communication is around 2km in dense urban area, up to 15km in the rural areas and is influenced by the position of the end device and of the gateway, if the gateway is mounted in an high place the cover will be major than if is mounted in a low place.
LoRaWAN™ is part of a bigger category of technologies named LPWAN, that stands for Low Power Wide Area Network, this technology was born for the necessity of sending and receiving messages from sensor that operate on battery, using the smallest amount of energy available to preserve the battery energy.
An excellent documentation of the LoRaWAN technology can be found here: https://www.thethingsnetwork.org/docs/lorawan/
