When we all carry personal phones around, will their be enough bandwidth capacity in the cellular system to handle all the phone traffic. How will the assumptions that underly capacity estimates hold up when more/most calls are made from/to callers static in a cell instead of moving from cell to cell ? Jeff Sicherman
