Q2. What is called as DTIM?

Ans.

DTIM stands for Delivery Traffic Indication Message, used in Wi-Fi networks to inform clients about the presence of buffered broadcast and multicast frames.

DTIM is a parameter in the Wi-Fi beacon frame that indicates to clients how often they should wake up to receive broadcast and multicast traffic.
It helps in saving battery life for devices by allowing them to sleep for longer periods of time.
Clients can set their power-saving mode based on the DTIM interval specified by th...read more

Q3. Difference between wifi AC and Ax

Ans.

Wifi AC is the 5th generation of wifi technology, while Wifi Ax is the 6th generation with improved speed and efficiency.

Wifi AC operates on the 5 GHz band, while Wifi Ax operates on both 2.4 GHz and 5 GHz bands.
Wifi Ax supports MU-MIMO (Multi-User, Multiple Input, Multiple Output) technology for better performance in crowded networks.
Wifi Ax offers higher data rates and improved efficiency compared to Wifi AC.
Wifi Ax uses OFDMA (Orthogonal Frequency Division Multiple Access)...read more
