For example, you can think of a cell phone network as a type of distributed system, consisting of a network of internet-connected devices that share resources workload. Software and hardware components are autonomous and execute tasks concurrently. Today, there are a variety of architectures and systems in use. Peer-to-Peer.

When it comes to latency the authors measured RTTs for four 5G base stations spread across the city, and 20 other Internet servers nationwide. Unsurprisingly, the more network traffic and hence the more you’re using the radio, the more power 5G consumes. It accounted for 55.18% of the total energy budget of the phone!
