IEEE 802.15.5 <strong>WPAN</strong> Mesh<br />
23<br />
• Additional promises made by the Mesh Task Group:<br />
– Extends distance <strong>and</strong> communication speed<br />
– Allows effortless installation of a communications infrastructure<br />
– Self-configures, is self diagnostic <strong>and</strong> self-healing<br />
– Provides resiliency, with no single point of failure<br />

Conclusions<br />
24<br />
• IEEE 802.15 <strong>WPAN</strong> Work Group was introduced<br />
– <strong>WPAN</strong> st<strong>and</strong>ards under active development<br />
• Increasing data rates to be expected<br />
• Low power consumption<br />
• Self-configuring networks<br />
• Coexistense of 802.11 is an issue<br />
• Future <strong>WPAN</strong> interests<br />
– mm-wave systems (@ 60 GHz)<br />
– Mesh networks (relaying)<br />
– MIMO?<br />
• Not (yet) implicitly included in IEEE 802.15 framework<br />
• Enables enhanced reliability (diversity techniques) <strong>and</strong><br />
capacity (spatial multiplexing)<br />
