No talking while doing Data: Phone problem or CDMA problem

[Alchemist]

2G, 2.5G, 2.75G, 2.99G, 3G, 3.5G and now 4G.....all marketing terms....they seem to mean whatever the latest hype is....

CDMA2000 is part of the 3GPP2 set of standards but is not compatible with the WCDMA (UMTS) version of 3G, which is part of 3GPP and used in most of the civilised world (i.e. outside the US! ) Even in the US UMTS is fast becoming available, so there is uncertainty about the future of CDMA2000.

On WCDMA it is possible to do voice and data at the same time but is a function of the type of device you have (the so-called 'class').

So in the case of the Neotel service it could just be a limitation of the device but it could also be a limit in the standard. Not sure.

If there is such a cloud of uncertainty, why on earth did NeoTel adopt this as a technology standard? Or is Tata dumping all their old technology on South Africa while they upgrade all their other operations?

The the 2.99G was used in jest.

The main question I was asking is whether no simultaneous voice & data was also inherent in the design of GPRS/EDGE, both at a CPE and network level?

I know, was kinda agreeing....

I think it was, but will ask the right people on monday.

Never underestimate the power of Qualcomm.
