CDMA 1x 2000, GPRS, 3G or EVDO is wireless or mobile broadband internet service connection which has unstable connection. They will have different speed all the long time while you are trying to access. Sometimes you got a high speed connection and another time they will have poor connection. CDMA 1x 2000 and GPRS service are working on the same channel with voice and messaging (SMS) services. It means while the traffic of both voice and messaging are on high demand, the CDMA 1x 2000 or GPRS connection will get poor one. Giving a priority and capacity is applied to each BTS for all services which used the same RF resources. And usually Telecommunication Company is giving priority to voice and messaging services rather than data service. Both services also have bigger resource RF capacity on the BTS rather than data service or mobile broadband internet service. We can understand it since right now the high demand from subscribers is voice or messaging service

To avoid poor connection on mobile broadband internet service, usually Telecommunication Company applies several technical and non technical solutions on the current network infrastructures. Non technical solution could be limiting the capacity of wireless internet subscribers. It means that Telecommunication Company will not expand network infrastructures to accommodate new subscribers and they only maintain the current subscribers. Meanwhile technical solution could be;

1. Adding new network infrastructures to cover the poor performance on mobile broadband internet service at certainty areas

By this mechanism, it means Telecommunication Company should install Base Transceiver (BTS) at the areas where wireless or mobile broadband internet service is getting poor performance. This is expensive way and usually they will do this mechanism once those areas are definitely lack of RF resources

1. Applying different charging bases

This is to differentiate the quality of service on mobile broadband internet service. To the areas where no RF capacity issue, time base charging is the first option. Meanwhile to the areas experience lack of RF capacity, charging system base on volume is fairy. This is avoiding more complaints from subscribers

Both mechanisms above are caused by RF capacity issue. Meanwhile RF capacity is not the main point where unstable connection to wireless internet service is going on. The other one is international bandwidth capacity. To optimize international bandwidth capacity issue, Telecommunication Company could apply one of the following mechanisms;

1. Inserting bandwidth management to the existing network infrastructures

Telecommunication Company will limit the bandwidth capacity to each protocol while subscribers browse to internet. For example, streaming video will only have 5 Mbps to all subscribers, downloading file has 5 Mbps, http protocol is highest priority etc

1. Inserting cache/shape engine

By this mechanism, Telecommunication Company will give an option to their subscribers whether the traffic they will retrieve on the laptop/compute is shaped or normal. While they choose shaping option, the speed will be faster but the quality image will decrease
