Q108. Which of the following are key features provided by SmartRadio?

Dynamic Frequency Assignment (DFA)

Intelligent load balancing

Enhanced distributed channel access (EDCA)

Airtime fair scheduling

Explanation
SmartRadio is a technology that provides intelligent radio resource management for wireless networks.
SmartRadio includes several features, such as Dynamic Frequency Assignment (DFA), which automatically adjusts the frequency allocation based on the interference situation; Intelligent load balancing, which distributes users among APs based on user density and traffic load; and Airtime fair scheduling, which allocates airtime resources fairly among users with different rates. Enhanced distributed channel access (EDCA) is not a feature of SmartRadio, but a standard mechanism defined by IEEE 802.11e to provide QoS differentiation for wireless multimedia applications.
