4G
Abbreviation for fourth generation of mobile networks
In short and in plain language
4G is a widely used mobile network for data on the go.
Test tools have profiles for it, fast and slow. They play back a typical phone connection.
Speed still varies here. It depends on reception and on how busy the network is.
Definition
4G refers to the fourth generation of mobile networks, which mainly includes LTE. Measurement tools offer profiles such as fast and slow 4G that simulate typical mobile connections with limited bandwidth and delay. Even on 4G, speed varies with reception and network load.
