Seems M$ knows where to advertise... I wonder if they'll sue me for copyright infringement because that image has their name in it..

I'm interested in talking to you. Check out my website and you'll find out why.

I have Tons of Positions(TM) open right now... we develop software to perform Radar Cross Section Analysis.


Now, for those of you who clicked before reading on, the only drawback is that I have no money, so there is no pay :) It's all just for fun, but still something you can do to keep your skills up and have something to put on your resume if you're between jobs. There are about half a dozen of us right now.. it isn't such a bad gig :)

My website's terms of service explicity state that all email sent to recipients at my server become my property and that the sender agrees that he/she has no guarantee of confidentiality, regardless of any content within the actual email.

Neat trick eh? It either becomes yours, or the sender commits fraud... my lawyer says it probably wouldn't hold water, but it sure as hell might scare somebody :)

Also, before you go run out and buy a high gain antenna, be mindful that any consumer access point has TWO antennae - one for transmit and one for receive, so you'll need two high gain antennae. Access points that only have one antenna actually do have two. The receiving antenna is external and the transmitting antenna is an internal stubby. here is a picture of the inside of one of my D-Link 900AP+ access points. You can see the stubby transmit antenna on the right.

What I did for my long-haul link is remove the coax and connector from another access point, and swapped it with the stubby. This leaves me with one access point having two external antenna jacks and one with two internal stubbies. The latter is fine for use around the house while the former handles my local hotspot. Here is a picture of my antenna pair.

I think I was able to put together a single AP/Antenna pair for about $700, which included the two antennae, the custom cables, the two AP's required to make one with two jacks, and all the necessary hardware, weatherproof enclosures, mounting frame, power over ethernet (homemade), and support structure.

The longest link I've been able to establish to date is a 9.1mile link at 1Mbit, which survived for about 45 seconds. I can reliably make 2 miles at 22Mbit as long as the other side has the same setup.

Federal law preempts the ability to complain about interference in the ISM band. This is unlicensed spectrum to which no one individual or entity has any elevated use rights over any other individual or entity. This is good for adoption, although overcrowding may become an issue.

Even if only consequential, Part 15 protects joe blow average user from any recourse from a big corporation that wants to use the spectrum.

I will probably have first-hand experience with this shortly, as my new free public hotspot is aimed directly at the Starbucks down the street from my eighth floor condo. :)

Unfortunately for me, the law only allows 36dBm EIRP for point to multipoint links, so I'm trying to get a point-to-point link with a friend of mine who lives just a little further down the street, in which case I'm allowed 48dBm EIRP (which for those of you who don't know logarithmic math, is almost 16 times as much power) :)

And yes, I do have a businees connection of which I am perfectly allowed to resell the bandwidth... Here's a picture of my antenna array, just before I added the isolation fence and other goodies to prevent coupling..

Just to put some things into perspective, here are some numerical results. These were obtained on my dual-athlon 1.4GHz w/ 1GB of RAM. The task was to compute the TE and TM surface currents induced on a circular cylinder 10 wavelengths in circumferece and having a relative permittivity equal to 4-j2. The program simultaneously solves the perfect electric conducting case. The surface was discretized into 60 cells using 120 unknowns (way overkill, but just to prove the point) using the Integral Equation Asymptotic Phase method.

g77 Compiler (-O2 -malign-double -funroll-loops): 24.11s
Lahey Compiler (equivalent paramters): 16.45s

As you can see, there's really no comparison, except that the lahey-created binary uses about 10% more RAM than does the one created with g77. This is just a summary comparison as I did not go into measuring the difference in the error of the two results compared to a reference solution. I'm assuming that both solutions are about the same with regard to accuracy.
