WiFiWiFi -- Native for Multiple Network EnvironmentNative for Multiple Network Environment

WiFi MAC – designed for multiple Wi-Fi networks

Carrier Sense Multiple Access (CSMA)/Collision Avoidance (CA) to sense

the medium for other transmissions before transmitting, and hence avoid

collision.

Also avoids collisions with hidden nodes by using RTS/CTS transmissions.

- -

same band

Recognizing the signature of the interference (e.g. microwave, baby

monitors, BT etc.)

Selection the appropriate WiFi channel to operate.

WiFiWiFi – – Power, Burst Rate and EnergyPower, Burst Rate and Energy

J=P*t

Low power/Throughput does not assure battery life time – talk ENERGY Higher burst rate enables shorter Tx/Rx on duty cycles and longer sleep modes

Wi-Fi has undergone generations of power optimizationfor battery applications… and we are not done yet
