5Ghz Networks

What are the ERP limits for the band? Also is there any type approval (just that there normally is on UK stuff )

Mean eirp (that mythical measurement):

Band A: 5150-5350MHz: 200mw

Band B: 5470-5725MHz: 1w

Band C: 5725-5850MHz: 4w

hmm anyone know about these, really odd but seems like a good idea, a wireless AP in a tube

the Atheros AR2313 SOC, MIPS 4KC, 180MHz
isnt so great/good but still perhaps useable for low speed/users point to point links.

its got a Linux SDK so good for the open source 3rd party firmwares too, anyone tryed it!

Fancy running some tropo(scatter) on 5GHz?

150miles at 4Mbps is not unheard of

"Power: High" (it's actually 2KW )

looking a little more, i found some senao/EnGenius that have a REALLY good name in the Open Source community,Due OC to their far higher generic power output (keeping in mind UP's max UK power warning above OC) and RX sensitivity -95dBm or better....! in the Band A internal kit at least, cant say about these Band B externals, but it seems better than most looking at a few specs,
but i cant seem to find a Uk supplyer for you ,but didnt try to hard...

oh you could aways go and get a few of these http://www.wifi-stock.com/details/ubiquity_rs.html RouterStation motherboards 44.66€ and populate with your choice of (upto3) miniPCi radio's

RouterStation Software Specs

RouterStation ships with OpenWRT Kamikaze. Ubiquiti only provides limited support for the software, but full support for the hardware.

All documentation for the use of OpenWRT can be found at the following website:
http://downloads.openwrt.org/kamikaze/docs/openwrt.html
Please look forward to a quick setup guide for a single radio setup.
"

its odd though , given the Pro nature of these boards and supplyers, they DONT seem to carry 11n miniPCI radio's or even list them, but we know they exist as they are in a LOT of laptops today... and senao/EnGenius make one or two...

a few of these could be fun to play with at 36.96€ with some high gain directionals pluged into them

Next you'll be using it for moon bounce

[popper]

perhaps easyer to use a laser and that old mirror the US guys put up there, the one some guy on a bicycle rides up a hill to a ground based laser every day and fires it at that moon mirror and he's proved that the moons moving away from the earth (very moonbase Alpha,1999) very slowly apparently...

i wonder IF you Might get somewere with a bigger version of this

1Gbps Wireless - Under $10K


LightPointe says their new laser optics product line delivers Gbps speed for under $10,000. The FlightLite G combines low cost-per-bit transport, high transmission security, and SNMP management capabilities hin a compact, easy to install, and fully outdoor-rated unit, says the company.

but i'v gone a little OT with that...ROTFL

Moonbounce is great if nobody answers, with the delay you can always have a convo with yourself Trying to run data over EME would be interesting. Some of the big guns in the US are running 36ft dishes on 70cms.

You can get 99% reliability over 1200KM with forward ionoscatter on 50MHz. That would be 40-50KW into a 500ft rhombic (18-20dbd). I wonder if I can get a NOV for 40KW

Impressive for the day indeed. In more recent times, Dave W5UN is the top man.
