That \"thing\" for cell phones costs about 5 cents to make, and sells in most places for $10 to $20. What it really does is enhanced the sellers pockets!
Speaking as a someone who has been in the wireless industry for 15 years, and a bench tech for much of that time. If that \"thing\" worked, the manufacturers would include it.
Some research on RF propagation would be pertinent to this discussion, given that phones are in the 800-900/1800-1900MHz range (depending on which continent you call home) and the Wif-Fi is in the 2GHz range.
Hacking RF is a little (sic) different than hacking linux. :wink:
That is *NOT* the thing that I\'m talking about!
I\'ve been a ham since 1979, received my commercial radiotelephone license in 1981, and a degree in electrical engineering in 1984. Was involved with radio long before any of that though. Worked for the Communication and Tracking group for ISS, see:
http://www.knology.net/~murphree/ and have been worked on two millimeter wave RADAR missile seeker programs.
This is essentially a re-radiator to be used in a car with an outside antenna and not the flexible pwb sticker scam that was sold. I haven\'t seen one advertised for a long time since most cell phones have added external antenna jacks since then. We do a similar thing at work with antenna \"hats\" for microwave transceivers.
WiFi is at 2.4 GHz as well as the amateur satellites that I have a S-band downconverter for.
It would feasible to build a coupling device for cards that do not an external jack. I dismantled a WiFi PCMCIA card recently and its antenna appeared to be a folded dipole when I was really expecting a patch. My next step is to hook up the DC-18 GHz spectrum analyzer that I have and measure antenna patterns from some of these cards.
The learning curve for hacking RF is probably far less than for Linux for most people...
