Several advances in GSM/EDGE and CDMA2000 radio solutions have been made specifically to tackle the challenge of delivering optimized radio coverage in regions where little or none exists today, in a cost-effective, low-risk way.
For instance, there are new radio systems using features to optimize downlink power and uplink sensitivity, that enable the delivery of much larger cell areas from a single Radio Base Station (RBS), reducing the number of radio sites required in a particular location. In this way, CAPEX per square kilometer can be reduced significantly - often by more than half.
The latest radio technologies offer coverage-optimized solutions that provide a very flexible way to add capacity as traffic demands take off - up to ten times initial capacity with just one site visit. However, the operator only has to make the decision to add capacity once traffic levels have grown substantially, reducing investment risk and making pay-back calculations more realistic.
In addition, a scalable mobile core is needed to support profitable penetration - so operators can build out their network step by step as the number of subscribers and capacity demands increase. In this way, investments can always be kept at a minimum.
