Does Cellular Data Drain The Battery Faster Than Wi-Fi?

The video explains the process of data transmission, involving the generation and propagation of electromagnetic waves using a transmitter and receiver. It highlights the power consumption differences between GSM and Wi-Fi, noting that mobile data generally consumes more energy due to the need to maintain a constant cellular connection. The video also discusses how distance affects power output and the impact of weak cellular signals on battery life.

What is the role of a transmitter in the data transmission process?

• To maintain a cellular connection

• To generate data and send it as electromagnetic waves

• To receive data from electromagnetic waves

• To convert data into a text message

How does the distance between antennas affect power output?

• Power output doubles with distance

• Power output remains constant regardless of distance

• Power output increases with distance

• Power output decreases by the inverse square of the distance

Which scenario consumes more power: browsing over GSM or Wi-Fi?

• Browsing over Wi-Fi

• Neither consumes power

• Browsing over GSM

• Both consume the same power

Why does mobile data consume more energy than Wi-Fi during streaming?

• Because Wi-Fi requires more power to maintain a connection

• Because mobile data does not use electromagnetic waves

• Because mobile data maintains a constant cellular connection

• Because Wi-Fi routers are farther away

What happens to Wi-Fi power consumption when it is not in use?

• It remains the same

• It drops close to zero

• It increases significantly

• It doubles
