As we move from 5G to 6G, edge computing is one of the concepts that needs revisiting. Its core idea still intriguing: Instead sending all data and tasks an end user's device cloud, possibly covering thousands kilometers introducing delays lower-bounded by propagation speed, servers deployed in close proximity user (e.g., at some base station) serve as proxy for cloud. This particularly interesting upcoming machine-learning-based intelligent services, which require substantial computational...
