Hi Esko,

Thanks a lot. I Will include your suggestions.

Ciao

Hi Luigi,

Thanks, this clarifies it I think! So now there is a two-level hierarchy to apply PASA addressing.

To introduce the new acronym I would suggest:


in figure Figure 2, where a PLC router in each room

->

in Figure 2, where a PLC router (PLC-R) in each room



And change ‘TV bell’ to ‘door bell’ ;-)



regards

Esko

Hi Esko,



Would the following updates figure + text c be more clear and address you concern?



Ciao

3.2.  Smart Home



   Smart home or home domotica is another example, as shown in figure

   Figure 2, where a PLC router in each room is used to connect home

   appliances (boiler, dishwasher, fridge, etc.) and devices (lights,

   doorbell, sound boxes, etc.) to the Home Gateway.  The network can be

   further extended if a switch/router is connected.  As it leverages

   the power line distribution, the network forms a typical tree

   topology as well.  Some observations and considerations are:



   *  Usually a Home Gateway bridges the smart home to the Internet.



   *  The Home Gateway, the PLC routers, and most of the home appliance

      are fixed in different locations.  They rarely move after setup.



   *  The smart home automation requires any to any communication.



   *  Lightweight communication stack with limited MCU and RAM

      consumption is desired.
