The discussion was closed on 24 august 2018 with a consensus to merge. Cell vs user throughput in simple words cell throughput is the packet bits sent by transport layer per second to ue, while user throughput is the received bits by ue per second. They tell you two different things about the data in your network, but theyre closely related. If your calculated throughput does not meet your applications baseline throughput requirements, you must increase the bandwidth of the resource that you identified as the bottleneck.
This is called the 3 db bandwidth, also known as the cutoff frequency. Understanding latency versus throughput system design. Throughput for the purpose of this article will be understood to be measured from the arrival of the first bit of data at the receiver, to decouple the concept of throughput from the concept of latency.
