5. The Main Drivers of 5G Mobile Data Traffic: Thousands of times growth Mobile Internet & IoT Connections: Up to 100 billion

6. Services & User Demands Users expect better, yet more cost-effective, services and experiences with mobile internet and the IoT. In addition to satisfying cost and experience demands, 5G will also need to meet extremely high security requirements, particularly for services such as e-banking, security monitoring, safe driving, and mobile health. 5G will also be able to support lower power consumption to build a greener mobile communication network and to enable much longer terminal battery life, especially for some IoT devices.

7. 5G Scenarios & Performance Challenges The 5G scenarios include at least dense residential areas office towers Stadiums open-air gatherings Subways fast ways high-speed railways wide-area coverage. These scenarios, which are characterized by ultra-high traffic volume density or ultra-high connection density or ultra-high mobility, may be quite challenging for 5G.

41. All-spectrum Access All-spectrum access can exploit a variety of spectrum resources for mobile communications, including high and low, paired and unpaired, licensed and unlicensed, contiguous and non- contiguous frequency bands, to increase data rates and system capacity. The frequency bands below 6 GHz are preferred due to their good propagation characteristics. The abundant unused spectrum resources between 6 GHz and 100 GHz can serve as supplementary bands of 5G. The main challenges of all-spectrum access include channel measurement and modeling unified access for low frequency and high-frequency bands unified high-frequency access & backhaul implementation of radio frequency (RF) components.

43. Efficiency Requirements 5G needs to make significant improvements in the following aspects: Spectrum efficiency: 5 ~ 15 times Energy efficiency: 100+ times Cost efficiency: 100+ times
