Let's say in 2008, you wanted to add additional wifi hotspots around your house. Wirelessly.
Well, you could have been doing it using DD-WRT (Router Firmware) on basically any old wireless router you had lying around.
Advance yourself ten years. And you've realized now people are adding Power Line extensions and wired access points. Small outlet hot spots. All virtually with different SSID's (Different Networks).
Why...? I have to ask, WHY do people continue to do this? The wall hubs have slim to NO power. TX or RX'ing
You're constantly struggling to keep them connected. And all the while, your device has to actively choose which network to be on/stay connected to.
Why not drop routers in place. On the EXACT SAME SSID, (2.4Ghz and 5Ghz spectrum) -- Have your "Smart" device choose which is the best signal. (Because it should)
I'd tell you the router I use, but I don't get money from them, nor do I have stock in the company. But for a small price. You can take a wireless router. -- Search for wireless SSID's -- Rebroadcast THE SAME SIGNAL.
It sounds too easy right? -- Well, it is. Most people just don't understand they can do this. Not to mention (HERES THE SECRET) remember wireless "Channels" -- That's how you extend wireless networks. You keep them off seperate wireless spectrums so the signals don't collide. (1, 6, 11) They have to be 5 segments a part.
On the 5Ghz spectrum it's 36, 48, 57, 149, 157 --
I still feel it's what we've shoulda been doing for the past twenty years. Unfortunately, society advances slowly. What do I know, I'm not a developer. :)
