Power line carrier seems good solution since Echelon LonWork
launchment. However, it faces barrier of power line performanc
quality. Thus, it seems to be better solution of ZigBee to replace
PLC. Zig-Wave is spin-off from ZigBee alliance to enhance easy-
deplyment policy to kick off the wekness of ZigBee.

We devote great effort to ZigBee home security and building automation
in Taiwan. Our goal is build ZigBee sesnors around a small home to
link to internet world.

Meantime, we put more human resosurce to overcome sophistake useage of
ZigBee. For instance, we try to build a easy HW and SW interface to
have users to set up home security by DIY.
