well, isn't that what mobiline and extelcom didn't do when the GSM networks came in the market?

they were too complacent! they were too late to introduce new services / products that would match the offerings of the GSM networks even though the CDMA is also capable of doing all that.

now, where's mobiline and extelcom?

Now you bring out the CDMA, it would be fitting to share with you some comparisons of GSM and CDMA. CDMA is a recent technology alright and its logically had it’s roots older than GSM as it was used in WWII, Cuban Missile Crisis et al. The technology was tested effectively in 1991 for cellular communications. Hongkong was the first one to implement CDMA.

If you take the large wireless operators in US, most of them use the CDMA technology. Big firms such as Sprint, Verizon wireless et al support CDMA, while T-mobile and Cingular support GSM.

CDMA, comes up with:

Increased security for wireless communications
Duplex conversations
increased efficiency that allows a large network to handle traffic effectively (better return for buck spent)
Better battery life for phones as low power consumption
Better capacity and reach,


This means that it has cons too.

No international roaming
Newer technology
proprietary technology
WCDMA will not be available in Europe/asia till 2005 while GSM successor GPRS and EDGE is already in our hands.


Right now, GSM is a clear winner with 5-1 usage demographics. If you wanna have a worldwide coverage, go with GSM. That is why CDMA didn't take-off much here in Philippines. So obviously Mobiline adapt GSM with the help of merging with SMART.

Hope that was a useful enlightenment.
