Need Advice/help setting up Network

[Thenasty]

I need some advice of how and the best low cost solution.

I am helping out a School extend thier LAN/Internet connection to another building across the street. How far, you could throw a baseball from the one building to the next building, thats how close it is. So I figured maybe 35 yards/125 feet give or take.

There is a good LOS (line of sight) from the second floor from each building. I am aiming fo the First PLAN i roughly draft using Paint Shop. Where there is a RECEIVER on Building 1 and a Transmitter on the 2nd building which will be connected to hub/switch roughly 24 ports. I will like have to wire up the buidling 2 for this plan.

Second option I;m thinking is, from Building 1, a RECEIVER and from Building 2 Only the Workstations have the Transmitters (W-NIC). I am concern about signal strengh.

They just want to connect roughtly about 5 PC's in building 2, so they can access the Internet.


TIA for the any advice.

I would set up a wifi bridge using two routers set up as bridges. I dont know what you mean by "transmitter and receiver" tho... Networks are duplex so the interface devices will be transceivers. Wifi G would be good enough for the distance, but N has a better range. If you go your second route, it would cost more per each computer they added, and you would have more reliability problems. With two routers bridged you can place them in optimal locations.

thanks protokatie


So the best and low cost solution (range/signal will be no problem) will be something like this ?


the Linksys WET54G (Bridge)

Yup

Check out black box.  I did a similar setup to link a local church and rectory via wifi.  Put 2 wireless/switch/accesspoints in bridge mode in the two buildings, with an omni antenna in an attic window on one end and an external panel antenna on the other side.

The access points will only talk to eachother - no external access.  Turn on WPA and you even get half decent encryption.

Directional antennas will also make the system much less susceptible to noise and interference.  At minimum a omnidirectional gain type antenna will give a better signal but a directional antenna is best in ptp applications.

Except that we all know that some DB will come around and try to "improve" the connection by moving ---steaming pile of meadow muffin---. This is why a good omni antenna might be the best practise. Besides, from the sounds of the OP it is a minimal distance.
