To maximize frequency spectrum efficiency, Allocated frequency for LTE
technology should be concerned about further upgrade to LTE-A technology
21. 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.
