WIreless Bridge/Antenna Layout Question

Renegade 34G
Level 1
Level 1

I'm trying to figure out the best way to get network to a remote building which is about 1000 feet away and to a parking lot just below the remote building. I attached a simple diagram which shows what I'm discussing.

 

Distances

Main building to Remote Building: 1000 feet.

Main building to farthest end of parking lot: 1600 feet

Remote building to farthest end of parking lot: 100 feet

 

Needs

Remote building: less than 10 devices, PC/laptop, scan gun, printer, etc.

Parking lot: 2-4 security cameras

 

I need to get network connectivity to the remote building and to the parking lot. There is currently no power to the parking lot. I would be able to mount the AP on top of the main building which would be about 80 feet in the air. Between the main building and remote/parking lot is nothing but open field. Very easy to shoot a wireless signal I think.

 

My question is, could I use a directional antenna to shoot from the main building to the two locations assuming the antenna will arc 180 degrees? I was thinking I could have a point-to-point from main building to remote building using a bridge and have wireless signal to the security cameras.

Or should I get three access points with antennas? One on main building and one on the remote building doing a point-to-point and the third using a directional to shoot to the parking lot giving wireless signal to the cameras?

 

Also, is there a document that lists the distances per antenna/ap? I found a couple documents but some state that the AP’s can only go up to 500-1000 feet and I’ve seen some that say they can go miles.

Directional antennas (yagis) typically have a small azimuth (angle of radiation).  I didn't see where you indicated the azmith between the remote sites, but I suspect trying to hit both sites with a yagi at the head end is optimistic.

I typically place a high gain omni at the master, with directional antennas at each remote end.  Going 1,000 feet isn't an issue... I have links much longer than that.

If there is doubt, then do the math :

AP tx power + antenna gain - coax loss - free space loss = recv signal level
