The problem is that Bluetooth is VERY short range so large distances wont work. It is designed to allow devices to communicate when they are physically close together without the hassle of plugging it in. That would mean multiple gateways around the home that would either communicate with higher power RF signals, or dare I say it....be WIRED together. 

 

Of course. I allow myself one mistake a year. That was it ;-) 

 

802.11 carries over a much greater distance thereby creating a different problem, when it is affordable enough for all your neighbours to use, the band will be flooded and even if the security issues are sorted (which would probably mean extra data for encryption) the throughput would slow down.  

 

It isn't a big deal. It is the same security as people use when setting up a VPN to access a corporate LAN "through" the internet. In fact handing over encryption to the OS actually improves things. I think that everyone agrees that wep is a total waste of time. 

 

Network congestion is why people upgrade from Hubs to Switches to partition the LAN effectively into separate LAN's. How do you partion the atmosphere ??? 

 

By using different channels 

 

As Mark said, each technology has its place but a cabled solution, whilst more hassle to implement, will always offer more bandwidth and greater security and greater flexibility. 

 

Phil has seen my house. I've said it before. It would cost THOUSANDS to install a wired system in my house, which is fairly typical of modern building practices. Unless you are installing a wired system at the building stage then a wired system is highly impractical. Come back and have the same conversation in five years, and I guarantee that HA will be more mainstream and it won't use CAT5! 

 

One of the driving forces behind the development of KAT5 was the fact that despite there being 47 channels in the UHF TV band, I couldnt find channels that would remain free from interference to allow 8 different signals to be distributed. 

 

Even in terraced houses there are enough channels in an 802.11 system to avoid conflict provided neighbours are prepared to cooperate, even in high density environments.
