Not sure on the distance, but have you looked at free space optics?

I have a number of links that are about 3 miles in length, and looking
for the MOST COST EFFECTIVE solution to create high capacity
throughput (45 mbps FDX or 100mbps HDX or higher), and conserve the
precious unlicensed spectrum under 6Ghz used for PtMP last mile to end
user (5.3 and 5.8 Ghz, etc).
60Ghz - Can't go the distance :-( (rumored comming down as low as 9
grand)
70 Ghz - Adequate. 4X distance of 60Ghz. But way to expensive. (40
grand - 1Gb).
92 Ghz - Adequate same distance or greater than 70Ghz. But way
expensive. (40 grand- 1Gb, 22 grand -100mb Fdx)
38Ghz - Adequate range. Radios super cheap from surplus or Ebay. (as
low as $1000). Must pay license fee to license holder (although as
little as $50 a month).
The advantage of the 90Ghz technowlegy is their pencil beam size, that
makes interference near impossible. So for longevity possible worth
its price.
So my question is....
What other options are there? Are there any?
I know there is 26Ghz unlicensed.
Any of the options sub $10,000?
So far, it looks to me that the lowest cost solution is to get some
surplus 38Ghz gear.

Subject: [WISPA] Frame size update (Matt,et al). VL nows supports 1600
bytes +
Well Matt, thanks to your questions I pushed them through the
Alvarion R&D
folks and wanted to inform y'all of what I learned. I discovered that
BreezeACCESS VL as of version 4.0.23 supports jumbo packets of 1600
bytes +
4 bytes of CRC. If VLAN is used the length is the same 1600 + 4
bytes. It
works both ways UL and DL. Engineering has apparently tested it with
Smartbit card 7710 type. Same while inspecting the packets with
Ethereal.
So is that adequate for what you and others are doing, such as with
MPLS?
