How Mobile Phones Work Behind the Scenes

adamengst writes "We seldom think about how our mobile phones actually work, but in this TidBITS article, Rich Mogull pulls back the covers and peels away the jargon to explain why text messages work when voice calls are dropped, why your battery lasts longer in some places than in others, why you're not allowed to use phones on airplanes, why you can be notified of a voicemail message when your phone never rang, and more."

      You forgot the best part about texting. Assuming it's not at night, you can do it more inconspicuously while driving!

    1. Dial number, tower recieves signal and discards number.
    2. Dial again, tower connects and routes call around the world before connecting to the called number.
    3. Tower waits for conversation to begin and injects random noise, removes every third word, and then disconnects.

    However a friend of mine who is a balloonist years ago told me what happened when he used a cell phone in flight - chaos! ... multiple cell towers cannot easily handle being contacted by a single phone moving 500miles an hour.

    Holy shit! What type of balloon was your friend piloting? Was it one of those Led Zeppelins I've heard so much about?
