Summary

• Tablet, Portable PC, Video content and Cloud service would be key drivers to boost up network traffic.

• In next 5 years, Subscribers will grow 3.4 times while Data traffic will increase 9.5 times.

• At least 50 MHz spectrum would be required to support our forecast data traffic in 5 years

• Ways for efficient utilization : Coverage prospect, Capacity prospect, Capacity offload prospect

• Technology aspect, LTE would give better spectrum efficiency. LTE-A would make even better spectrum efficiency.

• 20-40 MHz bandwidth assigned by regulator for LTE-A and further new technology should be taken into account.
