Is this hotspot link possible?

    Hey, I have been looking around the forums trying to get some info to setup my own hotspot. After doing some research, I was left with a lot of questions. Here's what I'm trying to do. I am creating a 1.3 km omni hotspot so that people in my neighborhood could do LAN games and transfer files wirelessly. The main problem is the maximum height is 1.5m (for the router) and it will be indoors. Also, some of my users will have no line of sight due to multiple houses in the way.

    Hardware - I was planning to use a Linksys WRT54G because none of the people that would connect would have SpeedBooster and I'm not sure if I need the extra RAM. I was wondering what version would be the best, and is the SpeedBooster add-on worth the extra $20 (CAD)? The versions I heard that were good are WRT54G V2.0 and WRT54GS V1.0.

    Firmware - I was thinking of using Sveasoft's Alchemy Firmware but I am open to suggestions. Most of my users will want to bridge routers (if possible) and I wanted to have user/password logins for all users and redirect them to a webpage. (Like at any normal hotspot when they first access the web) Also, bandwidth management features that set bandwidth restrictions for each individual user would be nice.

    Extra Equipment - I am willing to buy some extra omni antennas and I will push my power up to 250mw, but I am not sure if that will be enough, because wouldn't they need the same setup on their end? It could be possible for them to get extra antennas (except their budget it’s much smaller than mine so nothing too expensive)

    I am wondering if such a link is possible with this equipment and if I could keep it all within a $250 CAD budget. Also, if more equipment is needed, feel free to post so I can save up and do this link in the future.

    this isn't something easily acheived, you could use multiple routers and setup a WDS link for everyone but you may need more routers than you have depending on physical layout and who is participatinjg in your wlan.
    cranking the power up to 250 mw is a BAD idea you'll be burning out routers quicker than you can say "oh crap i just ruiend my router" which i'm sure will displease you and probably your neighbours even more so if you turn theirs up to 250 when it croaks... one of the WDS experts here can probably give you some advice but you'll probably need a router every house or two for it to work reliably.

    I have done some more accurate measuring, and the farthest target I would need would be 800m away. Also, what would be a safe power output on the router? 100mw?

    thats a pretty far distance, you'll definately need several links in between if you don't have high gain LOS directional antennas.
    100mw would even be pushing it, i've got my tx power on one of my routers at 75 and it doesn't seem any worse for the wear... you might need additional cooling, etc for higher powers.,..
    furthermore turing up the power also increases noise so you may end up having worse signal than before...
