Re: GoCDMA Pakistan
Yaar UMTS is based on W-CDMA (Wide-Code Division Multiple Access) … Yes CDMA has slightly different standards in other countries like in Japan where it’s called CDMA-2000 … The main difference to the GSM Networks is the Technology it’s based on … GSM uses TDMA (Time Division Multiple Access) … which isn’t sufficiant enough for broadband services/purposes … The only problem with CDMA is, that it has a “breathing feature/problem” in the Network … means once the number of users becomes high in a certain area at a time the range of the Broadscasting-Cell becomes shorter … the higher the number of users in a certain area the shorter the range of the respective broadcasting cell … that’s why sometimes u’ll have drop-outs or in other words “no Service” in crowded areas … It’s designed to maintain the speed of the service which then causes the drop-out of certain users who have a greater distance to the Broadcsating-Cell than others … means if u r only 3km away from it and someone else is 6km away, he is more like to be dropped-out of network than u …
In Japan they had to increase the number of the Broadcasting-Cell upto three times of the originally planned number … that causes higher roll-out (set-up) costs for the Service-Provider … That’s why most EU-Countries waited until UK rolled out and they could benefit from their experience …
