MKT, don’t get me wrong. I haven’t had said that 3G network is built for speech services ONLY – or have I?
I only disagree with you in that sense that it also makes sense to use it for speech. In some countries – it makes a lot sense to expand their wireless network (based in GSM) by using WCDMA technology, not GSM – and this is so, because with same amount of money operator get more capacity for both voice and data.
