LoRaWAN Classes
LoRa-Alliance.org
LoRaWAN device classes
CLASS NAME INTENDED USAGE
A
(« all »)
Battery powered sensors, or actuators with no latency constraint Most energy efficient communication class. Must be supported by all devices
B (« beacon »)
Battery powered actuators Energy efficient communication class for latency controlled downlink. Based on slotted communication synchronized with a network beacon.
C (« continuous »)
Mains powered actuators Devices which can afford to listen continuously. No latency for downlink communication.
Typical Device Examples
Class A: Report status a few times per day
No planned actuation required
Extremely low energy
Class C Maintenance and index info a few times per day
Constantly listens for network «ping»
For low-latency actuation
Class B Report moisture, a few times per day
Turn valves on or off
with a few minutes latency
Very low-energy,
which depends on latency

Coin Cell battery life
• Low power is essentially a protocol issue
• LoRa uses an asynchronous access method : no network access fixed cost
• Mainly limited by battery self-discharge

Security
LoRa-Alliance.org
Security Design objectives :
• Reference to a well known security framework
• Make it possible for end users to transport data opaque to the network
— re-use of IEEE 802.15.4/2006 Annex B (CCM*)
— RFC4493 (MIC)
— Separate integrity and encryption secrets
— AES 128 with 128 bit key length
