5Ghz Networks
 

I am looking for a decent 802.11a access point/client unit but not one with b/g support as it is going to be for a backhaul on my network, i have setup plenty of 2.4Ghz networks but i need some extra range on this one as it will be over 10 miles unless someone can point me in a better direction.

Re: 5Ghz Networks
 

Do you have any expectations of access speed?

Re: 5Ghz Networks
 

well i only need to have about 2meg throughput.

Re: 5Ghz Networks
 

Quick, back of fag packet calculation with LOS between the sites and a 22dbi panel antenna at each end* fed with 5m cable of you should be good for about 11 miles at 6mbps.

Don't forget your licence ;)

*Based on the bridge's power output & gain factors staying with in legal limits

Re: 5Ghz Networks
 

Can you recomend a make/model because a google at it finds loads of a/b/g stuff i just need a 5Ghz only! argh google

Re: 5Ghz Networks
 

No probs:

Re: 5Ghz Networks
 

I wish i could afford such luxuries do you know anything in the lower price bracket, as im trying to get a few customers in the new area im moving into to see if its viable to purchase better equipment? i looked into buffalo as i find there kit is unbreakable but found nothing in the 5ghz stuff.

Re: 5Ghz Networks
 

OK this Net-El one is a far cheaper alternative and seems to be a common offering around the lower price points but I have no idea as to the efficiency or robustness of this kit. It's a dual band bridge: 2.4GHz and 5GHz Band B/C

Re: 5Ghz Networks
 

iv no idea if this will get the longer range, id rather go for 22DBI highly direction dish types but something like this panel with intigrated wireless to save on the cable loss perhaps...

the 5Ghz doesnt need a licence, you can get long range with unlicenced open kit too, with the right directional high gain arials over line of sight for point to point and point to multipoint setups....

oc your going to get a lot better coverage with 2.4Ghz 11N if you use highly directional line of site, assuming if you dont have a lot of 2.4Ghz between sites...

the spec of that Motorola PtP 400 lite Bridge Kit Includes:
2 x Motorola PtP 400 lite Units
2 x Mounting Brackets
Price: £3,456.00 (£3,974.40 inc. V.A.T.) kit is a little OTT today for 22Mbps it seems, you could get a microwave 1gigE radio for that...

Re: 5Ghz Networks
 

Operation in bands a and b are licence free but don't forget that the maximum permitted eirp is significantly lower than that of the licensed band c and you would technically be breaking the law if the gain of the antenna you were using caused you to exceed these limits.

That's just the official line of course...

Re: 5Ghz Networks
 

true, but you are allowed to use as high a power / by DB gain so as to cancel out any pigtail connector loss and cable loss you might get in the total output calcs, it takes a little more thought but doable to keep it totally UK legal.

Re: 5Ghz Networks
 

There's a useful-ish calculator on here which provides a rough idea. You have to play around with the figures to suit the UK regs though.

http://www.cisco.com/en/US/products/hw/wireless/ps5279/

I have a slightly more involved tool here but it most certainly isn't in the public domain ;)

Re: 5Ghz Networks
 

i cant find the page now , but i seem to remember that all UK external unlicenced Point to point wireless kit gets a higher total DB gain/power allowance rating than your average internal consumer wifi kit, for some reason upto 200mW seems to stick in my mind, but cant find the page to verify Doh!

Uncle Peter, are you a radio Ham or Pro radio guy playing with your interesting wireless toys ;)

Re: 5Ghz Networks
 

Thanks for the input the item from solwise seems to be good, like i said its just to try and get some usomers in a new area my main links are usually SAF 7.5Ghz they are amazing and i get nearly 100meg throughput on those!

Re: 5Ghz Networks
 

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

Re: 5Ghz Networks
 

Mean eirp (that mythical measurement):

Band A: 5150-5350MHz: 200mw

Band B: 5470-5725MHz: 1w

Band C: 5725-5850MHz: 4w

Re: 5Ghz Networks
 

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!

Re: 5Ghz Networks
 

Fancy running some tropo(scatter) on 5GHz?

http://www.marcorsyscom.usmc.mil/sit...m/TRC-170.html

150miles at 4Mbps is not unheard of

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

Re: 5Ghz Networks
 

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 :angel:(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...:sleep:

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

what did you end up going for benny?

Re: 5Ghz Networks
 

Next you'll be using it for moon bounce ;) :D

Re: 5Ghz Networks
 

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) :erm: very slowly apparently...

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

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

Re: 5Ghz Networks
 

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 :D
