Why 5G will be helpful even when 4G already provide more than enough max speed

1. Capacity

   With the devlopment of megacities on the earth and the development of Internet of Things, there are more and more people concentrated inside megacities and each people will have more and more devices connected to the wireless network, which would create congestion. With the introduction of 5G technology, it is expected to support more simutanious connection as well as allow higher total tranmission speed so that the speed can be experience by each individual device in dense environment can be improved.

2. Latency

   With the emergence of SNS, VoIP, mobile gaming and other time sensitive applications, mobile users are becoming more sensitive than ever to delays. Reduced latency can provide a much better user experience to whom that are using their wireless device for any near-real-time purposes

3. Energy

   Less energy consumption, more longeivity to your mobile devices, wearable devices, and cut the carbon footprint and energy bill

4. Mobility

   Enable the use of mobile data on high speed trainss without additional equipment that would otherwise be moving too fast to establish reliable connection. Possibly also improve aircraft connectivity.

5. New applications

   AR/VR/4K/8K/3D/AI/machine learning/cloud computingetc. are all new applications coming onto mobile that would require more and more data speed that would require nenw higher speed connection to handle.

6. D2D

   Bluetooth/Wifi direct/wigig/NFC?

Why Long Term Evolution LTE is not enough
