Free wifi... info, and then questions...
First off, I just found out that Comcast is putting up free wifi access points all over the place. They are apparently built right into leased routers that they put in peoples homes and they are now turning them on.
I checked it with my smart phone on the way home from work last night... most of my hick town all of a sudden is one big free wifi access point...
With an external antenna I am pretty sure I would have really good coverage in much of my daily journey...
So that is the end of the "info part"...
Now, the question part...
First some background -
I am putting together a carputer system that will have a carputer in my truck, as well as wifi cameras in the horse/llama trailer that I will tow. I want that connection to be done wirelessly via wifi (Foscam cameras).
I also want to be able to connect to my home network when I pull into the driveway so I can download mp3's and such. I have a decent wifi access node at home (about 50 watts ERP - range about a mile).
So, I want to be able to to connect to my LAN, as well as any free wifi access points (Comcast infinity, McDonalds, Starbucks, JiffyLube, etc
I am not a wireless or network expert by any means. From what my thought process tells me right now, I think I might need two, or maybe three wifi xcievers in my truck to do what I need to do... One on the truck LAN side as an access point so that the trailer cameras can connect to it, and one one the truck WAN side (in client mode) to connect to free wifi access points.
I also want to connect to my home network... not sure if I would do that via the WAN client mode wifi xcvr or would I want another xcvr set up in bridge mode?
This is all starting to sound insane.
Any thoughts, suggestions?
I really don't want three antennas on the truck. The WAN antenna will of course be an external antenna for max range. The LAN antenna only has to go 25 feet or so max (to the horse trailer), so I can probably avoid an external antenna for that. My house is about a hundred feet from my driveway and my outside wifi access point antenna is about 10 dbd gain with transmit amplifier and receive preamp, so that should not be a big deal to connect to.
Also, can a wifi xcver in the "client mode" be configured to connect to a variety of access points automatically (home, xfinity, mcdonalds, starbucks), or do they want to be hard configured to connect to a single SSID?
Any thoughts, suggestions from those wiser than me would be appreciated.
