Wireless TCP/IP application over 500' outdoors

I have an electronic photo finish system that runs over ethernet using 100mbps cable. Because of multiple finish lines outdoors, I would like to run this on a wireless 802.11n network at a distance of up to 500'.
I have been successful indoors in the range of 25-30' using a Linksys router as an access point and but outdoors the performance drops off to unacceptable at about 100'. Any ideas on how to extend the range and do this outdoors?

Consider using a Meraki (www.meraki.com) MR58. Both long range, offers directional antenna, and enviromentally safe for outdoors.

The Meraki looks like it would work but is a bit too pricey for this application. Since this is always a temporary setup - usually for a single day - it doesn't have to be "industrial strength. It can also be reasonably well protected from the elements. Is there something that would use an external antenna with a more standard off-the-shelf router or access point?

Most outdoor units are in that price range. If you indicate you can protect it from the elements, you might consider an MR16 at about a third of the cost. This AP does not have external antennas, but should do the job. You can obtain up to 3 units on a test basis from Meraki, so you can try before you buy. Given that you move them, the cloud controller feature might be of interest.

If you don't want a new AP, then consider a repeater to relay the signal.

If these AP's are outdoors and isolated, then how do you power them? UPS?

Oddly enough, there always seem to be outdoor outlets where there are finish lines. We do use UPS units for the cameras and would plug in an access point or router as well.

I know nothing about repeaters. Can you enlighten me? Thanks.

A repeater would go somewhere in the middle between the remote AP's and the receiver, depending upon range. Since you use Linksys, here is one of theirs.

You could certainly buy it cheaper than at the cisco store.
