Can any of these experts please *quantify* these enormous costs incurred by cellphones that happen to be in the vicinity of a cell tower? What *percentage* of capacity does a non-communicating cellphone occupy when it is not currently transmitting or receiving? In my *expert* opinion, these are insignificant, immaterial costs. And rightly so, since the cellular infrastructure is engineered to minimize such costs! This is essentially nonsense. On 02/09/2010 05:49 PM, Dave Farber wrote:

The cell has to reserve codes (CDMA), time slots (TDMA), or channels (OFDM) for any client with which it has established a conversation, and can't continuously do this for every cell phone in the vicinity.Dave, It's worth mentioning that this applies to wired broadband too; every connection means a session allocated on an ISP BAS, and equipment is usually spec-ed for X simultaneous PPPoE connections; in fact, Cisco charge significant license fees to ISPs based on the number of concurrent connections (active or not). -- AlexArchives
