OK, so?
● We will ship:– 50M smoke and co detectors– 40M to 50M appliance controls– 10M water heater controls– 5M thermostats– 1 – 2M refrigeration controls– ...
● We want to/need to/must interconnect these devices!

Goals
● Lots of Sensors – 100s; Many controls – 10s● No new wires; Reduce installation costs● Inexpensive - < $3 modules● Internet Connectivity● Open Standards

Open Standards
Standards are great – everyone should have one.
actually
“Efficiencies of proprietary solutions will be overcome by technology advances within one
development cycle”

What about Zigbee
● SNL● Stack is too:
– large – 64K– complex– expensive– untested– not IP compatible

Barriers to deployment● New Radio● New MAC – CSMS/CA plus GTS/Beaconing● New Network – AODV plus Cluster Tree● New API – Zigbee API plus ZODs● New Application
● CSMA/CA only MAC● AODV and IP● Sockets and SNMP
Risk Mitigation
