Assuming you mean 1000 METERS or 1 km, linear not area, even with a perfect area of coverage (flat or below, not obstacles with perfect line of site) that's a pretty tall order. Is this a consumer/hobby usage or professional? Consumer products you should consider linking several routers with some type of bridging/repeaters/WDS. You can use cheap routers (under $30) with DD-WRT firmware if they are Broadcom based and you are comfortable with basic networking and firmware flashing. Or you could purchase out-out-the repeaters to fit the location (wired, wireless, powerline, etc. ~$100) If this is for a commercial or professional, there are plenty products -rather "solutions"- at the price and supports levels one would expect. Same stuff they put on top of a telephone phone or power tower is some areas.
