In practice, because this transmission is once in a while, the amount of cross interference should be in-significant. On the other hand, I am more concerned at the robustness of the protocol used and its real-world ability to get the data across without being interfered.
Is this technology going to interfere with WiFi? (is it broadcast at 2.4GHz?)...I already have so much interference with 7 devices at home that try to connect to connect not to mention all my neighbors that in some rooms have stronger signals than my router...strangely enough freshly purchased iPAD is the worst while two iPhones never get messed up, some laptops come in the middle losing Internet connection only ocasionally, so is the wireless printer...do I need another wireless signals at home? NO! (in addition I do have wireless garage door opener, security system and few cordless phones in addition to smart grid meter my energy supplier installed without my knowledge)...Kris
