Summary take away

Summary• 5G Evolution plans will pave the way to the next-generation of higher speeds for

customers • Not waiting until the final standards are set to lay the foundation • “Data on our mobile network has increased about 250,000% since 2007” (Donovan Jan

2017)

• Greater speed and overall network performance brings huge opportunities• Video, IoT, 4K video, AR/VR, smart home and cities, autonomous vehicles and
