ABP stands for Authentication By Personalisation. It means that the encryption keys are
configured manually on the device and can start sending frames to the Gateway without needing
a 'handshake' procedure to exchange the keys (such as the one performed during an OTAA join
procedure).
With ABP the encryption keys enabling communication with the network are preconfigured in the
device. The network will need to provide you with a Device Address, Network Session Key and
Application Session Key.
