Wireless Link Calculator On A Cell Phone
Casey Halverson writes "Ever been out in the field and wanted to make a quick wireless link calculation, but didn't have a computer or internet connection handy? Or maybe you're just too lazy to turn the thing on? Well now you can, from your xHTML capable cell phone. PocketSOM can calculate a wireless link, telling you your signal strength, whether or not it meets local FCC/IC/EU regulations, and even an expert analysis system that will tell you how you can improve your wireless link and what kind of performance you can expect. People like us (the SeattleWireless admins) are using it right now - here's a screenshot."
What's my link now? *walk a little* What's my link now? *walk a little* What's...

Crudely Drawn Games
This is pointless Any good engineer can do it with a slide rule!
"Ever been out in the field and wanted to make a quick wireless link calculation, but didn't have a computer or internet connection handy?"
Yes, I have that problem all the time! Why should an average Joe like me struggle with complex trigonometry when this handy little device let's me do wireless link calculations in the field like a pro? No more time consuming manual wireless link calculations for me. Are you still doing wireless link calculations with a fiddly old wireless link calculation slide rule? Throw it in the garbage! You don't need it anymore thanks to this handy gizmo. Don't be a laughing stock because you can't do quick wireless link calculations in the field... act now!
By the way, what's a wireless link calculation? (Don't you love it when an article assumes you know exactly what it's talking about?)
Read Pynchon.
What's your GCNSEQNO?
WAP / XHTML applications like this can be a lifesaver. Why don't we spend more time deveoping these and less time porting inane games to our phones? (Because games create money)
Make sure you keep the image quality high enough to capture every nuance of the subtle faux wood-grain background (and by background I mean 68.3% of the image), not forgetting the coffee cup stain.
Be sure to include the whole of the phone including every dialing digit, because that gives context to the screenshot.
Well done. You passed the 0.5 Mb threshold, but still shy of the 0.6 standard. Try a brightly coloured background (a stained tartan kilt plus sporan should do) next time. Remember you want to get to at least 1.5 Mb so it won't fit on a floppy.

it doesnt even validate
you do know about doctypes, character encodings and how xhtml and html parsers work right ?
without a doctype using or even calling it xhtml is worthless and the parser will use plain old html quirks mode (aka html 3), good effort but no cigar, you could of also scripted this in WMLS then the client would not need to post forms and would be able to update the display in realtime, the user could even use it offline then and store the WML locally.
and you call yourself a nerd ?
"Ever been out in the field and wanted to make a quick wireless link calculation..."
Umm, no. I have; however, been out in the field and wished my cell phone would get a goddamn signal.

DRM is like antifreeze, to the MPAA/RIAA it's sweet, to the consumers it's poison.
"Ever been out in the field and wanted to make a quick wireless link calculation"
Nope. Next question.
It can be done using only software modifications! It's how some network operators measure their networks. I've seen a picture of around half a dozen mobile phones (each a different make) attached to a piece of wood, with cables plugged into the standard connector on the bottom, running back to a black box (think it was actually a laptop). The system then logs field strength for each phone as a function of position (GPS is also attached).
Wouldn't this be better suited as a Java MIDlet? What if you have no signal? What if the server is down? No additional bandwidth charges (for those with carriers that do). And probably quicker response times. And no worries of the site being slashdotted.
Document the calculations and I'll make a MIDlet in a couple of hours. I can find basic equations, but they take into account additional variables (cable loss, receiver related variables) which you don't use.
it measured the actaul field strength of your wireless link. If you are doing field meseaurements you would have your laptop or wireless equipped PDA with you anyway. I really cannot see the fscking point or carrying around another bit of gear that does less than all the other bits of gear I carry around.
