SUPPORT OF ZIGBEE HOMEPLUG STANDARD IN ELECTRIC METER

Currently Zigbee use for Smart Energy (SE) Demand Response Home Area Networks in multiple dwelling units (MDUs) and in some home types is a problem due to Zigbee devices targeting the 2.4 Ghz band an location of meters versus location of living area.  Problems also exist depending on the type of material the residence is made of.  This description addresses supporting Zigbee SE 2.0 Homeplug in electric meter as an option board since the option board will only be deployed in a sub-set of meters that require homeplug.  The sub-set includes approximately 6% single-family units, 100% of multiple dwelling units, homes with electric vehicles, and homes with HAN devices that utilize Zigbee based Homeplug controllers (appliances in the future).

The current electric meter solution is to provide Zigbee via an Ember 357 port on each meter.  Homeplug requires adding support over the SPI interface and utilizing general purpose IO pins to flag communication to SPI flash or SPI on Homeplug chip on an option board.  The GPIO pins should also be wired to support a serial interface to Homeplug chip option board because some Homeplug chips use a serial interface instead of SPI.  Use GPIO pins as chip select control to select SPI flash or Homeplug on the option board. 

This approach will allow devices on the HAN to look the same over wireless and over the wired Homeplug interface...
