HIPERLAN 1 MAC Layer
nCompatible to ISO MAC
nSupports time-bounded services via a priority
scheme
nPacket forwarding
–support of
directed (point-to-point) forwarding and broadcast forwarding (if no path information is available)
–support of
QoS while forwarding
nEncryption mechanisms
–mechanisms
integrated, but without key management
nPower conservation mechanisms
–mobile
terminals can agree upon awake patterns (e.g., periodic wake-ups to
receive data)
–additionally,
some nodes in the networks must be able to buffer data for sleeping terminals and to forward them at the
right time (so called stores)
