The Wirelessly Home Area Network Application

• Enable the wireless interconnection of electronic devices within the home– Low and high speed throughput– Real time and non-real time data– Support prioritization and guaranteed bandwidth,

latency– Multiple simultaneous connections– Enable coexistence, interoperability, coordination

between all home devices– Coexist and interoperate with “visiting” or legacy

devices designed to other standards

Why Networked?• Coordination mitigates the Train Wreck

– 802.11b WLANs will enter the home this year– 802.15.3 multimedia apps target the home– Wherefore wireless VOIP phones?– Still have Bluetooth, HomeRF, 2.4 GHz cordless phone, microwave oven interferors

• Networking is the logical extension of– Necessary device coexistence– Desirable device interoperability

• Need not add much cost

The General Application Idea• A “Wireless Network Coordinator” (WNC), acts as a home

radio spectrum traffic cop• The WNC controls transmissions from all 802.11b and

802.15.3 devices in the home, assigning priorities and allocating bandwidth as needed

• Devices associate and communicate directly with each other

• Signaling occurs at data rates exceeding 40 Mbps, providing multiple simultaneous links

• 802.15.3 rate scales down to 802.11b– The WNC is an 802.11 point coordinator
