Glossary

access control list (ACL): A data table used by a device to determine which devices are authorized to
perform a specific function on the network.

ad hoc network: An ad hoc network is one created in a spontaneous manner. It usually has a short temporal and existense.

coordinator: An fully functioning device (also called FFD) that can provide synchronization services
by transmittng beacons. If a coordinator is the principal controller of a personal area network
(PAN), it is called the PAN coordinator.

device: Any entity ( RFD or FFD) containing an implementation of the IEEE 802.15 medium access control (MAC) and physical interface to the wireless medium.

fully functional device (FFD): A device capable of operating as a PNC or a device.

logical channel: The physical link is divided to logical channels.

personal area network (PAN) coordinator (PNC): The principal controller of a personal
area network (PAN). For example, in IEEE 802.15.4 - a network has exactly one PNC.

packet: Concated bits that are transmitted together across the physical medium.

personal operating space (POS): The space around a person or object that is typically about 10 m in diameter. The person can be in motion or stationary.

reduced-function device (RFD): A device operating with a minimal implementation of the IEEE
802.15.4 protocol.

wireless medium (WM): The medium used to implement the transfer of protocol data units (PDUs)
between peer physical layer (PHY) entities of a low-rate wireless personal area network (LR-WPAN).
