Supported Protocols

IEEE 802.15.4

The 802.15.4 is a standard developed for Wireless Personal Area Networks (WPANs). WPANs convey information over short distances among the participants in the network. They enable small, power efficient, inexpensive solutions to be implemented for a wide range of applications and types of devices. Some key characteristics of an 802.15.4 network are:

  • An over the air data rate of 250 Kbit/s in the 2.4 GHz band.
  • 16 independent communication channels in the 2.4 GHz band.
  • Large networks (up to 65534 devices).
  • Devices use carrier sense multiple access with collision avoidance (CSMA-CA) to access the medium.
  • Devices use Energy Detection (ED) for channel selection.
  • Devices inform the application about the quality of the wireless link (Link Quality Indication).

The 802.15.4 Standard defines two network topologies, both using one and only one central device (the PAN coordinator). The PAN coordinator is the principal controller of the network.

  • Star Network Topology – In a star network, all communication in the network is either to the PAN coordinator or from the PAN coordinator. That is, communication between non-PAN coordinator devices is not possible.

  • Peer-to-Peer Network Topology – In a peer-to-peer network, communication can occur between any two devices in the network as long as they are within range of one another.

Zigbee

Zigbee is a specification for a suite of high-level communication protocols using small, low-power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). Zigbee is targeted at RF applications that require a low data rate, long battery life, and secure networking. Zigbee and IEEE 802.15.4 based networks consist of many devices working together supporting sensing and control applications. Ubiqua PA has support for Zigbee 2007 stack profile 1 and 2, application Zigbee profile HA, SE, HC, CBA and TP2:

  • Zigbee Stack Profile 1 (also known as Zigbee).

IETF 6LowPAN

6LowPAN is not a protocol, is the name of the working group in the Internet area of the IETF. The 6LowPAN group has defined encapsulation and header compression mechanisms to allow IPv6 packets to be sent and received over the IEEE 802.15.4 based networks. The base specification developed by the 6Low PAN IETF group is RFC 4944, the problem statement document is RFC 4919. Several functionalities have been obtained from this work:

  • Adapting the packet sizes of the two networks IPv6 and IEEE 802.15.4.
  • Address resolution.
  • Differing devices designs.
  • Differing focus on parameter optimization.
  • Adaptation layer for interoperability and packet format.
  • Addressing management mechanisms.
  • Routing considerations and protocol for mesh topologies in 6LowPANs
  • Device and service discovery.

Zigbee Light Link gives the lighting industry a global standard for interoperable and very easy-to-use consumer lighting and control products. It allows consumers to gain wireless control over all their LED fixtures, light bulbs, timers, remotes and switches. Products using this standard will let consumers change lighting remotely to reflect ambiance, task or season, all while managing energy use and making their homes greener. Some features:

  • Long battery life mesh technology.
  • AES 128 encryption used to protect lighting network against unauthorized use.
  • Interoperable with other Zigbee profiles.
