Does congestion happen on all networks ?
Yes. Call congestion tends to occur during the busiest times in the network, such as the busy peak hour drive times or at major events when there are a high number of users trying to make a call at the same time. Whilst it is difficult to eliminate congestion fully, Optus minimises the likely occurrence of congestion by adding additional capacity to base stations or placing temporary sites at major events such as V8 SuperCars events, Indy 300, AGP, The Melbourne Cup and New Years Eve.
