  1. GSM

  2. CDMA

  3. TDMA

  4. AMPS
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

CDMA (Code Division Multiple Access) is a cellular network technology that uses a spread-spectrum modulation technique. This allows multiple users to share the same frequency band without interfering with each other.

Multiple choice

What is the term used for the technology that allows multiple users to share the same frequency band in a cellular network?

  1. Frequency reuse

  2. Time division multiple access (TDMA)

  3. Code division multiple access (CDMA)

  4. Space division multiple access (SDMA)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Frequency reuse is the technology that allows multiple users to share the same frequency band in a cellular network. This is done by dividing the network into cells and assigning different frequencies to each cell.

Which cellular network technology was developed by the Telecommunications Industry Association (TIA)?

  1. GSM

  2. CDMA

  3. TDMA

  4. AMPS
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

AMPS (Advanced Mobile Phone System) was developed by TIA and was the first cellular network technology to be deployed in the United States.

Multiple choice

What is the term used for the technology that allows multiple users to share the same time slot in a cellular network?

  1. Frequency reuse

  2. Time division multiple access (TDMA)

  3. Code division multiple access (CDMA)

  4. Space division multiple access (SDMA)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Time division multiple access (TDMA) is the technology that allows multiple users to share the same time slot in a cellular network. This is done by dividing the time slot into smaller time slots and assigning each user a specific time slot.

  1. GSM

  2. CDMA

  3. TDMA

  4. LTE
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

LTE (Long Term Evolution) was developed by 3GPP and is a fourth-generation cellular network technology. It is designed to provide high-speed data rates and low latency.

Multiple choice

What is the term used for the technology that allows multiple users to share the same spatial area in a cellular network?

  1. Frequency reuse

  2. Time division multiple access (TDMA)

  3. Code division multiple access (CDMA)

  4. Space division multiple access (SDMA)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Space division multiple access (SDMA) is the technology that allows multiple users to share the same spatial area in a cellular network. This is done by using directional antennas to focus the signals from the base station to the users.
