  1. Passive Relaying? by nacturation · · Score: 4, Interesting

    I assume the "no active relaying" prohibition means that someone can't have waypoint stations to pick up and rebroadcast the signal to the destination. So this leaves the competition open to passive relaying.

    How well does the 2.4GHz spectrum interfere with power lines? Would it be possible to put up a structure so that it modulates the power signal which is then decoded on the other end in a similar setup? At the very least, it might win a "Most Creative Bending of the Rules" award or something. :)

  2. Not necessarily power limited by elgatozorbas · · Score: 5, Interesting

    Because WIFI operates in the microwave territory, you need a line of sight (LOS). These waves do not go 'around the bend', as e.g. long wave radio does. 'Around the bend' also implies 'around the Earth'. I can imagine that at some point the winners of this contest will no longer be limited by power, but by finding suitable high places to transmit and receive from.

  3. What would really impress me wouldn't be 35 miles by usurper_ii · · Score: 2, Interesting

    line of sight, it would be a three to five mile radius working through trees...and even hills. Now someone pulling that off cheaply and legally would be like pulling Excalibur out of its rock and it would impress the hell out of me. (by the way, I'm involved in a wireless ISP that is getting hammered by the local terrain).
