Engineer - Once you have done this, then you must fill back in the holes you created. If you have ever seen the reuse pattern for a K=7 (i.e. frequency can be reused every 7th cell), then you can see that once you put the first one in you have to put in like 28 cells to build the coverage back up.

Just FYI, Analog averages a reuse of 7 cells, but NA-TDMA averages about 4 and GSM around 3. Still, a significant pain in the rear when you need move to denser population of users.

It would be MUCH better to swallow his ego a little, spend $5B on a CDMA upgrade everywhere (via OVERLAY using LUCENT equipment) and cut his losses

The killer is executing a smooth transition of handsets without losing their installed customer base. No easy answers.

I stand corrected. thanks Clark, Engineer for clarifying the frequency re-use issues. It sounds as if capacity gains created in a TDMA system by adding cells are even more difficult than I previously assumed but that additional spectrum is not required.
