BUX,

It is more economic that anything here. You can stack microcells in TDMA, but like you say it is quite tricky. the big problem is that once you bisect a cell, you have to turn it's power down so that the adjacent cells cannot see you or interfere with you. 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. Unless BTS equipment got real cheap lately, this means for every double in capacity you have to spend 20-30 times in equipment. I do not think that wiht AT&T already at an economic disadvantage of 4:1 they need to go out and make that 28:1.

Basic answer....you can't get there from here and if Armstrong has market guys running his show rather than engineering econ people, he will be swept out faster than his predecessor...

I can't wait for the tracking stock to roll out, because they will have to raise $5B just to try to get back to even. 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. But corporate face can be a terrible thing to overcome. Look at ERICY.....
