| Chinese theater to zap mobile phone users |

| Because many Chinese theater-goers are notorious for refusing to turn off their cell phones during the performances, the Shanghai Grand Theatre will install a "ray gun" that jams all incoming mobile phone signals. |
| Unfortunately, this would never work in the US because some loudmouth would sue the theater owners. |

| Except that it won't work for CDMA by MysteriousStranger 10:26:57 pm mst / 25 December 2000 / # 1 |
| CDMA uses spread spectrum, which was developed (in a far more primitive implementation) during WWII precisely because it's nearly impossible to jam. Strangely enough, it was invented by Hedy Lamarr. Who says beauty and brains can't coexist? In its modern CDMA form, it's even more difficult to jam. |
