| How do I read these numbers?
I have some question for ask:
What do these numbers mean?
With antenna modif----Without SRN -------=98 ------= 68 Signal+ ----=-1 ------= -1 Noise- -----=-100 ----= -100 SNR+ ------=99 ------= 99 Signal -----=-2 ------= -32 Noise ------=-100 ----= -100 Flags ------=001 -----= 001 Beacon ----=100 -----= 100
I have some pictures but I don't know to post it.
Thanks! |

| Looks like a good mod to me... but then I can't be the judge (conflict of interest ). Anyone else?

| reply to Ssoc Well, I was hopeing someone else would read them for him as I am not so sure I understand what I see there. It looks like he has a 30 dB better link, some of the other numbers don't feel like they agree with that.
Takers?

| reply to Ssoc Ikarus, Thanks for your reply, I did check your link about antennas, it is what I did.
I'd like to know if it's better or not.
Thanks! |

Yeah, it's a better link, one hell of a lot better. Stick one on the AP too.

join:2002-07-01 23490 | reply to Ssoc The apparent 30 dB increase in signal could be explained if the author (Ssoc) actually built two of these and put one on the AP and one on the remote.

| Ssoc;
Did you build one or two of these reflectors? Did you put one on the AP and on the USB device? I ask because the signal figures seem high!? I would like to know why your signal figures show 30 dB improvement in link? This is very high, too high, actually. What width are your reflectors? They look like they are eight inch reflectors, is that correct?
Thanks in advance.

Yes I built two reflectors, but I only used one because there was not difference using both. The reflector size is about 1/3 round can (maybe 1 more) by 3.5 |

| Cool! LOL, wouldn't you know. All we have done is make an improved "Pringles" antenna!!! Well guys enjoy this puppy.
When time permits, I'll revisit it. I have a couple of links to drop in tomorrow, and am building a nice new version of the outdoor AP. You'll like it when it is done. It's kinda pretty, actually.

| reply to Ssoc You guys intereted in one of these parabolic designs built as a clip on?
As I type, I have on my desk the plastic mold that will duplicate (but with a high degree of accuracy) a five inch design of this reflector.
We are looking at the possibility of marketing them. For outdoor installs they would have to be completely enclosed, but I can get you ten dBi, with an F/B around 20 dBi, pretty cheap. I think the first run will be about 200 pieces. After those are sold, we'll talk about mass production.
Excellent device for short haul LOS work, also excellent for security appliations in SOHO environments.

| A little ingenuity goes a very long way...
Just a $.99 cookie sheet is all you ever really needed, or an empty Foster's can and a pair of tin snips, or that pringles can the fellow above documents. Get any of those at any corner store and save yourself the drive, or use a nickel's worth of tin foil that was the point, wasn't it? Some people can do something with nothing, other's need consultants (award winning consultants, to boot).

The program used to model that reflector was 4Nec2. It can be found here:
»www.qsl.net/wb6tpu/swindex.html
The DWL-650 does not have a means to attach an external antenna, so there is very little you might do to improve it's antenna except to modify the card to accept an external antenna. Here is a link on how to do that:
»c0rtex.com/~will/antenna/
Finally here is another hack of the DWL-650 that worked quite well for me:
»osiris.urbanna.net/antenna_desig···rt_dish/
To be quite honest though, I really like the "Kipper Tin" biquad design or a discone design for laptop use. Look at these:
Biquad »manuka.orcon.net.nz/wififi.jpg »manuka.orcon.net.nz/wifibowt.gif »manuka.orcon.net.nz/wifibiqd.gif
Discone: Well... I see the only page I knew of that shows how to make one is gone, so I guess that will be then next thing I do on the web site.
