Linksys Signal booster...

Configuration and operational information about stumbled AP's

Linksys Signal booster...

Postby renderman » Sun Nov 24, 2002 8:58 pm

Since the crash, the original post was lost, but someone was inquiring about the new Linksys AP signal booster.

I got a chance to check these out.

It stacks on top of the AP and runs a little patch cable between the AP antenna hookup and the booster, the antennas get moved to the booster.

I asked about the stats and was informed that until the FCC cert came back they could'nt say, but a little bird told me it's near 1 watt and the antennas are about 24db

Should be shipping in the first week of December.

renderman,

Thorn had posted the original message, how did you get your hands on one? are they available anywhere yet?

any idea on price yet?

i had emailed linksys and got the following:

The WSB24 should be out in 4-6 weeks. Please keep checking the website for official announcement


Thanks

renderman,
I think the figures they gave you were inflated, or somebody misunderstood something. Here's why:

The original antennae are 2.2dBi or so. If the amp is about 30dB (1 watt), and you merely move the existing antennae, then total output would be in the 32dB-33dB (1.6 to 2.0 watt) range.

A 24dB antenna added to a 30dB unit would boost the level to 54dB (about 200 watts), which far exceeds the FCC/Canadian levels for Point-to-Point 802.11b transmissions of 48dB (50 watts).

I have seen on another board, that these are about 24dB (250mW). That may be speculation, but would still be legal to add a 24dB antenna to that level of output.

Of course, it may lie in the middle someplace, where it is legal to use the original antennae, but not a big dish.

Quite likely. The antennas on the unit are the original 'rubber ducks', so all the gain is from the AMP, not any aditional antenna.

I have seen on another board, that these are about 24dB (250mW). Of course, it may lie in the middle someplace, where it is legal to use the original antennae, but not a big dish.


When I asked what the output was, they said '24db'. The refused to tell me directly what the wattage was, though from my line of questioning it was confirmed to be a bit below 1 watt.

Apparently the FCC approval was supposed to be given on Friday, so it should be available on thier site shortly (I have no idea how to look)

eamonn: Comdex had a few for show, but they were'nt in use which was a good thing since there was enough 2.4Ghz traffic as it was. They are saying first week of december for shipping.

24dB = 250mW, which is what I'd heard elsewhere. If they refused to tell you what the wattage is, but gave the output in dB then they probably didn't know how to convert. I'm assuming that they were marketing (not engineering) types. They were probably told "24dB", and told to repeat it if asked.

As far as the FCC site, you can search on brand names, models, etc.

Linksys products have a grantee code of PKW-(some more numbers here).

Go here (fcc-id search page) and type in 'pkw' in the grantee code and hit search.
All the linksys products show up. I just checked and didn't see this device listed.

This is a good page that will convert mW to dBm and vice versa.

Yup, YDI has all sorts of nice calculator pages. Not everything you needed for 802.11b, but almost!

Does anyone know how to build their own signal booster? Having to buy additional products to add functionality that should be there in the first place is not my idea of fun.

Building your own amp is generally a bad idea. It's difficult even if you have electronics building experience, due to the critical measurements and the test equipment needed to do it right. The ARRL has the books you'll need. Don't forget to observe the FCC limits.

One thing is for sure.

A device like this will make stumbling much easier. When dealing with WLAN RF, more isn't always better. If somebody is able to pick up your signal 2 blocks away vs. having to sit outside of your business or home, you become much more vulnerable to attack.

2 WAP11's strategically placed in a home or small business will offer just as much coverage for the same money, and also has the advantage of load balancing... among others.
