What is DTIM (Delivery Traffic Indication Message)?

A Delivery Traffic Indication Message (DTIM) is a sort of Traffic Indication Message. It tells the user about the buffered broadcast information presence on the access point. It is created within the periodic beacon at a frequency determined by the DTIM Interval. A higher DTIM period might expand the potential savings in power utilization. It diminishes the communication throughput. The longer a user portable may sleep and therefore the more power that a specific user device may conceivably save, when the higher DTIM period.
