5G and Wireless Communication for Beginners - What is Frequency?

The video tutorial explores the evolution of mobile communication from 1G, focusing on analog communication. It explains simplex and half duplex communication, highlighting their limitations. The transition to full duplex communication with the use of towers is discussed. The concept of frequency is explained using a ball analogy, emphasizing its importance in radio communication. The tutorial concludes with a brief overview of frequency bands used in communication.

What was the primary goal of the first generation of mobile communication?

• To enable video calls

• To make two radios communicate

• To browse the internet

• To send text messages

In simplex communication, what is the main limitation?

• Both parties can only receive messages

• Only the receiver can send messages

• Only the transmitter can send messages

• Both parties can send and receive simultaneously

What is a key feature of half duplex communication?

• Only receiving is possible

• Simultaneous sending and receiving

• Alternating sending and receiving

• Unlimited range

How did full duplex communication improve upon half duplex?

• By allowing simultaneous sending and receiving

• By reducing the range

• By eliminating the need for towers

• By using digital signals

What role do towers play in full duplex communication?

• They connect directly to the receiver

• They extend the communication range

• They are not used in full duplex

• They only receive signals

What does a frequency of 0.5 Hertz indicate?

• Half a cycle per second

• One full cycle per second

• Two cycles per second

• No cycles per second

In radio communication, what can frequency range from?

• Kilohertz to gigahertz

• Meters to kilometers

• Seconds to minutes

• Bytes to megabytes
