Maximum Bitrate is a key QoS parameter in mobile networks that helps to manage bandwidth allocation. It is a Quality of Service (QoS) parameter, that defines the maximum data rate of a specific service or traffic flow.

MBR allows the network to better manage its limited radio resources, especially during periods of high network usage or congestion, by limiting the maximum data rate for certain services.

Maximum Bitrate is not the same as the actual experienced data rate, as the actual data rate depends on various factors such as network congestion and device capabilities.
