I think the world record is 310km for WLAN...
...I wouldn't want to be anywhere near the transmitters though!!!

Symbol sells antennae strong enough to cover this distance but one has to assume that it is L.O.S. only, obviously it is not specified in their brochure.
As codecref wrote before me, depending on the actual obstruction between the two buildings, i would not be surprised is a stronger antenna made it the full distance based solely on signal dispersion. If the obstruction is totally opaque then you would have to set up a relay/repeater on a structure (building or other...) that shares a L.O.S. with both the transmiting and the receiving ends of the signal. Of course this option works just fine but doubles both the cost and the paper work involved since you need permissions to setup a relay on someone else's structure.
Good luck anyway,

Gotta say, after just experiencing a situation with a power issue, go with Redline radios AN50's for this solution. use a relay point that is line of sight, and probably a 120' agl monopole. The cisco solution with 1410 radio's and 28dbi dishes would not work over 5 miles at 100mwatt. so beware of this model, on paper it works fine, in real life with no Fresnel zone probs, and no LOS issues over 5 miles is a non-solution with cisco and the FCC approved 100mwatt power setting.

Look at Orthogon,
They have the best NLOS PtP kit available today.
If you have an option to "daisy-chain" the wireless hops you may be able to go round or up and down in some way.
The kit costs about £8k here in the UK. So pretty expensive.
- have similar technology at cheaper prices, but are routing rather than bridging.

i got a Linksys 802.11G accesspoint and SMC 200mw Laptop card to link with an external HyperLinktech Patch Antenna
HG2418P 1.5 miles.
BTW FCC rules allow a full WATT without a license.
