Physical Channel Conclusions Communication works quite well under laboratory conditions

Most newer technologies are not yet ready for SE deployment

Yes, switched power supplies and certain devices affect thecommunication and the system is dynamic and unpredictable

Filtering helps a lot

Communication at peak times, in dirty environments and

between separated circuits are problems

There is still work to do and some issues needto be solved until we get there Lets do it!

Conclusions

Reliability, low cost and ease-of-use are crucial

One of the strengths of ZigBee is the SE-Profile

PLC may solve Basement-Access-Problem

Combining ZigBee RF with PLC (or other media?) Increases accessibility and reliability

Creates new opportunities on both sides Never underestimate technical challenges resultingout of suboptimal communication media types

First tests with the proposed bridge look promising

In our view SEP V2.0 incl. IPv6 is the way to go
