The terms CDMA and GSM are associated with

  1. direct-to-home television.

  2. telecommunications.

  3. life and General Insurance.

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

CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) are both mobile telecommunications standards used in cellular networks. They are fundamental technologies that enable mobile phone communication, not related to DTH, insurance, or airlines.

Multiple choice

_________ is/are canalization protocol(s).

  1. FDMA

  2. TDMA

  3. CDMA

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

FDMA (Frequency Division Multiple Access), TDMA (Time Division Multiple Access), and CDMA (Code Division Multiple Access) are all channelization protocols. They divide the available communication resource into channels - by frequency, time slots, or codes respectively.

Multiple choice

What is common between a GSM (Global System for Mobile Communication) network and EDGE (Enhanced date for GSM Environment)?

  1. Both deliver a data rate of 382 kbps

  2. Both use the TDMA frame structure

  3. Both use the same transceiver unit

  4. Both use phase shift modulation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Both GSM and EDGE use the TDMA (Time Division Multiple Access) frame structure as their fundamental multiple access technology, with EDGE being an enhancement of the GSM standard.

Multiple choice

Spot the odd technology from the group.

  1. WiMax

  2. LTE

  3. 3G

  4. 4G
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

WiMax (Worldwide Interoperability for Microwave Access) is a different type of technology compared to 3G, 4G, and LTE, which are all mobile telecommunications standards. WiMax was designed as a broadband wireless alternative to cable/DSL, while the others are cellular network technologies that evolved through generations (3G, 4G) with LTE being a 4G standard.
