Edge computing is a networking philosophy focused on bringing computing as close to the source of data as possible in order to reduce latency and bandwidth use.
In edge computing, the edge network stands between the cloud and the end-users, thereby, bringing cloud resources very closed to the end-users. This consequently provides tremendous real-time data analysis, reduce latency, low operational cost, high scalability, and improve the quality of services
5G and edge computing are inter-linked technologies that both work on improving the applications’ performance by enabling vast amounts of data in real-time. Unbelievably, 5G increases speed the speed up to 10 times that of 4G. In 4G data, the expected network latency is ~100ms, whereas, in 5G, the predicted network latency is ~10-20ms. Edge computing drastically reduces the network latency by processing the data closer to the end-user. Reading between the lines of your question, I think you’re suggesting that the high bandwidth, low latency characteristics of 5G would make it just a easy to send the “raw” data over the network, do all the processing “in the cloud”, and send back any necessary action, all with a minimum of latency and with no real concern about bandwidth.
