• Bi-directional end-devices (Class A): End-devices of Class A allow for bi-directional
communications whereby each end-device's uplink transmission is followed by two
short downlink receive windows. The transmission slot scheduled by the end-
device is based on its own communication needs with a small variation based on a
random time basis (ALOHA-type of protocol). This Class A operation is the lowest
power end-device system for applications that only require downlink
communication from the server shortly after the end-device has sent an uplink
transmission. Downlink communications from the server at any other time will
have to wait until the next scheduled uplink.
• Bi-directional end-devices with scheduled receive slots (Class B): In addition to
the Class A random receive windows, Class B devices open extra receive windows
at scheduled times. In order for the End-device to open its receive window at the
scheduled time it receives a time synchronized Beacon from the gateway. This
allows the server to know when the end-device is listening.
• Bi-directional end-devices with maximal receive slots (Class C): End-devices of
Class C have nearly continuously open receive windows, only closed when
transmitting. Class C
