• Data rate is a trade-off between the communication range
and message duration
• Devices and applications have a unique 64bit identifier. When
the device joins the network, it receives a dynamic (non-
unique) 32bit address
• 7 bits are fixed for the Things Network and leaving 25 bits
that can be assigned to individual devices, a procedure
called Activation
• LoRa uses multiple 128bit AES, along with frame counters to
defeat replay attacks

• Over-the-Air Activation (OTAA)
• The preferred and most secure way to connect with The
Things Network. Devices perform a join-procedure with the
network, during which a dynamic DevAddr is assigned and
security keys are negotiated with the device
• Activation by Personalization (ABP)
• In some cases you might need to hardcode the DevAddr
as well as the security keys in the device. This means
activating a device by personalization (ABP)
• This strategy might seem simpler, because you skip the
join procedure, but it has some downsides related to
security
