performance when multiple concurring applications, each with different latency

and throughput requirements, compete for network resources. By using WMM,

end-user satisfaction is maintained in a wider variety of environments and traffic

conditions. WMM makes it possible for home network users and enterprise

network managers to decide which data streams are most important and assign

them a higher traffic priority.
