1W transmitter is only usefull when you have other end(s) also having 1W transmitters... And generally 1W transmitter is usefull in really long distance links etcetc...
But generally speaking there is no hard itself to have capability of 1W transmission, even when not used.

What I'm wanting to maybe use these for is in an ALIX board replacement for our co-op WISP's aging Orinoco AP1000 APs.
The Orinocos currently are using 1W amps, and it would be great to eliminate that.
We have distances of up to almost 10 KM from the APs to the clients.
Anyway, I'm going to buy one of these for my prototype and see how it performs - I was just wondering if anyone on the board had got one yet... _________________ linksys GSv2, Gv4, Gv2, GLv1, G-TM, Buffalo wbr2, whr, whr-hp, whr-g125, wli-tx4-g54hp, Moto wr850gp, Alix.3C2

Sash,
We're in our sixth year with hundreds of subscribers, and yes, we do need 1W APs.
I just think it will be better to try to do them with less devices. _________________ linksys GSv2, Gv4, Gv2, GLv1, G-TM, Buffalo wbr2, whr, whr-hp, whr-g125, wli-tx4-g54hp, Moto wr850gp, Alix.3C2
Well you are correct that 1W device will carry further than "normal" access point, but please you still have to understand that you clients will need 1W transmitter too in order to benefit anything, eg it doesn't help that you can yell far if other person can't yell as far as you in order to response.

Some of our AP antennas are 16 dBi omnis, some are 17 dBi sectorals, some are multiple sectorals with splitters, sepending on the AP.
Some of our Client antennas are 19 dBi panels, some are 21 dBi grids and some are 24 dBi grids - mostly also depending on location. Most clients are wrt54g(v<=4) some are buffalo HP, some are HGA 8186s, and some are old CB3 bridges.
our target used to be about 16 SNR at the accesspoint, but our new target is for an SNR of 20 at the accesspoint.
Anyway, I'll get this card and see how well it works in my Alix prototype. _________________ linksys GSv2, Gv4, Gv2, GLv1, G-TM, Buffalo wbr2, whr, whr-hp, whr-g125, wli-tx4-g54hp, Moto wr850gp, Alix.3C2

thats a rebranded compex card by the way ...
Just a quick clarification on that comment. I'm with Freespace Systems who brings you this radio...
It is true, this is an item that Compex is making for us. They are a key partner for us and build many items for us with our design input and specifications. This radio is one of them. It is not available from any other outlet other than ourselves and our distribution network.
I'll try to monitor this thread to answer any questions you may have, but I'm not a regular here.
Guys, he has a reason to use a high power card. He did mention that he is using splitters and possibly long run wires. Sash, as long as you compensate for the loss of running long wires and splitters, there shouldn't be any issues with it.
So yes, there is a benefit for a high power card in this case. I am sure that he is not trying to reach longer distances, he most likely is attempting to have a very strong signal with little loss from the transmitter to the antennas, and the antennas need to be very directional to be able to pickup the weak signals from the customers, so I see the need for multiple antennas in order to cover a large area. I don't see a reason for him being wrong, actually, seems like he knows what he needs. _________________ Firebox II with DD-WRT, 1 Atheros PCI card, 400MHz AMD K-6 2 CPU, 128MB RAM, 256MB CF Card

this is true for the sending path. for the receiving path its more complicated and not easy to handle. you cant compensate the ATT in a acceptable way. _________________ Forum Guidelines...How to get help
