Whatever.....anyway, has anyone noticed the divergence of T with the DOW? Word is that the funds are dumping DOW dogs to load up. Also, the IPO was oversubscribed by over a factor of 2. Not surprising (the volume), but it will need to be maintained for any type of strong jump. I don't see how that can happen in the near term. PS: E, I'm not an AT&T employee....I'm just a consultant for AT&T who is "spending" a past favor...hence the IPO allotment. Regards...

Generally, it is a non-productive use of time to engage in the TDMA/CDMA debate. However, in this instance and off the top of my head.... 1. Please comment on the fact that while CDMA originally promised a 10x capacity improvement, actual field results show that capacity gains on a system-wide basis have only averaged 4x - exactly what non-CDMA "proponent" mathematics predicted. 2. Please comment on the fact that CDMA equipment costs 3x more than the analog equipment it replaced - resulting in a relatively small improvement in capx cost per erlang for the carrier community which deployed CDMA. Juxtapose that metric against those carriers which deployed other digital air interfaces. 3. Please comment on the system design issues associated with the deployment of a high speed mobile wireless access system using QCOM's version of CDMA. For example, please discuss the implication for the system designer of the varying Eb/Nt requirements for the multiple modes of HDR. Here's a hint.... Message 11728986 4. On an operational basis, what will a near instantaneous high speed 2 Mbps burst do to the link quality of all other connected users both intra cell, inter sector and inter cell? If you wish to beat the drum for QCOM stock, be my guest though I don't think this is the place for it. However, a discussion of a carrier's decision to deploy CDMA or TDMA or GSM or some other alphabet soup air interface is a whole nother kettle of fish. ww btw, if you have trouble with question 4, try here...
