A few months ago, I attended the 5G World Congress and listened to discussions around the many challenges and technical requirements facing 5G technology.
The questions everyone wants solved are:
- Which services actually require 5G access technology? What types of content demand the fastest service? According to lectures delivered by leading mobile service providers such as DoCoMo and KT, 5G networks need to deliver higher date rates to support applications such as 3D hologram video, VR and live broadcast.
- How will the networks support the exponential growth of end-devices requiring service brought about by IoT? As IoT end devices are carrying different ARPU models, 5G should address this challenge in improved cost per bit technology.
- What is the best way to support critical services such as voice, and how to build private networks (e.g. for connected antonyms driving cars) with zero latency and improved QoS, avoiding outages?
As 5G will be commercially launched only during the 2020 Tokyo Olympic games, it was agreed that the road to 5G will be via GIGA LTE that delivers 1Gbps data rates already.
