Recently, 5G (5th generation technology standard
for broadband cellular networks or 5th generation wireless system) is
definitely a hot topic in the financial news and TV commercial, which is
depicted as the core technology affecting our future such as business models in
various industries (e.g. logistics, gaming, automated/connected vehicles), Cloud
& Edge Computing, and
lifestyles. As an active social media mobile
user following the fashionable technology, I am fascinated by how 5G can
pragmatically improve our working and social life. As a result, I try to explore what 5G can
really do from view of a technology novice.
The TV commercial is always highlighting 5G
with features such as high speed (10-20 times of 4G) and low latency, which are
crucial for IoT (Internet of Things), another closely
related hot technological concept. IoT
is generally portrayed as a network of things (devices/objects) with embedded
sensors, programs or other technologies where the things are connected and
communicated to exchange data over the internet. Riding on these connected data,
real time analytics, state of the art technologies like machine learning or AI,
connected systems could build up various SMART networked applications for us, e.g.
smart home, smart
office, enhanced VR gaming
experience, self-driving
car or connected cars, enhanced digital/video marketing with instant
interactions, smart
manufacturing, digital
transformation, etc.
Another powerful feature of 5G is that it can support up to a million devices per square
kilometer. This would provide a more
favorable platform for the Edge
Computing that allows computation and
data storage closer to the users or smart applications to improve the response
times and correlation of the connected devices, e.g. self-driving cards are
connected to ensure smooth flow of traffic and avoid accident. While Cloud Computing
provides the computing power and data storage resources to achieve economies of
scale, Edge Computing would be an enhanced version to address those system
applications closely connected and requiring fast response and instant
communications.
