Challenge #1: Growth in MobileChallenge #1: Growth in Mobile DataData TrafficTraffic▪

Fast growth in mobile data traffic is being observed

–

Growth is expected to continue

▪

Slower ARPU growth compared to traffic growth

▪

Indoor environment is important–

Mobile devices are used up to 70% of the time in indoor

▪

Higher frequency band could be allocated to 4G in the future▪

2.5GHz, 2.6GHz, 3.5GHz

Bandwidth AggregationBandwidth Aggregation▪

Carrier aggregation is already in LTE-A and DC-HSPA

▪

Different types of aggregation could be seen in the future–

Inter-eNB aggregation

•

Aggregating carriers from different eNBs–

Inter-mode aggregation

•

Aggregating FDD and TDD–

Inter-RAT aggregation

•

Aggregating 3G, 4G–

Inter-technology aggregation

•

Aggregating LTE and WiFi
