Re: GlobalSat BU-353-S4 GPS receiver

be sure to add the "-b"("broken", read-only mode) argument to gpsd. That will prevent the device from reverting back to binary mode and causing issues.

Re: Raspberry pi wardrivers?

While conceptually there may not be differences, in reality, there are. The question becomes, how crazy do you want to get with the RasPi based WD rig? Some observations: - I was unable to get more than 4 cards (regardless of distributing them across powered hubs) to work on the Pi. My goal was to g...

Re: Rasberry Pi

I have found (for 2.4GHz), a 4-card setup to be extremely effective, setting card 1 to stay on channel 1, card 2 to stay on channel 6 and card 3 to stay on channel 11, with card 4 hopping through channels 2,3,4,5,7,8,9,10,12 and 13). If you configure a 3 or 4 card system as mentioned above, prepare ...

Re: Antenna Test: Alfa APA-M04

I'm already using two 12dbi antennas inside my car, "looking" through the side windows, yet the Mobile Mark 5dbi on the roof still seems more sensitive. That''s not surprising. Any antenna outside the car will do (potentially much) better than an antenna inside the car. There may be (at least trace...

Re: Antenna Test: Alfa APA-M04

Ok... Here's the idea. I'm referring to this as "the CUBE". You take a square (wooden?) box, of about 17" or so, with locking lid... I'm wondering if lining the inside of the box with foil might add a "ground plane" behind the antenna to capture multipath. You "tile" 4 14 dB outdoor plane antennas o...

Re: Antenna Test: Alfa APA-M04

I think I have a design in mind. It would be a bit costly, but.... would satisfy all of your criteria.

I'm debating whether or not to acquire the parts and build it. If I do, I will let you know what it entails.

Re: Antenna Test: Alfa APA-M04

Perhaps it's time for me to quick messing around and get a copy of the ARRL antenna book. Perhaps I/we could design something, or figure out how to re-purpose a (1.2GHz?) ham antenna for 2.4GHz.

Re: Antenna Test: Alfa APA-M04

It's really too bad that there isn't a mobile whip equivalent to this:

Re: Equipment test: Alfa Signal Amplifier Booster

No problem. Glad I could help. Yea, giskismet just crams everything into SQLite, and you can access the data by using 'sqlite3 wireless.dbl'

At some point, I'd like to import all of my stuff into Postgres.

Re: Equipment test: Alfa Signal Amplifier Booster

Thanks for that information. I think I will avoid that particular model, at least for the time being. I've made some tweaks to my 2.4GHz rig. I used giskismet to load everything into one, cumulative SQLite database, and I did some queries to analyze channel usage data. Looking at my 120k or so APs, ...

Ha! That's what I was thinking when I saw the article!

Re: Equipment test: Alfa Signal Amplifier Booster

Just curious about your continued research/use of these amps? Is it making a difference? Can you see a consistent improvement in your ability to pick up APs with it? Which cards are you using this with?

Thanks!

Re: 4 Alfa AWUS036 series USB wifi networking cards compared

I just ordered a 51. I'm looking forward to putting that card into the mix. While using inSSIDER on my laptop at work, I noticed quite a bit of 5GHz activity.
