GSM (Global System Mobile), IS-136 (Interim Standard 136) and PDC (Pacific Digital Cellular) are the three most popular TDMA standards of second generation. AMPS is a first generation standard.
Which one is not a TDMA standard of second generation networks?a)GSMb)...
Explanation:
TDMA stands for Time Division Multiple Access, which is a technique used in second-generation cellular networks to allow multiple users to share the same frequency band by dividing it into time slots.
The options given are all second-generation cellular network standards that use TDMA except for AMPS, which uses FDMA (Frequency Division Multiple Access) instead.
AMPS (Advanced Mobile Phone Service) is the first-generation cellular network standard that was introduced in the early 1980s. It uses FDMA to divide the frequency band into multiple channels, and each channel is assigned to a single user at a time.
Therefore, the correct answer is option C, AMPS, which is not a TDMA standard of second-generation networks.
Summary:
- TDMA stands for Time Division Multiple Access, which is a technique used in second-generation cellular networks to allow multiple users to share the same frequency band by dividing it into time slots.
- GSM, IS-136, and PDC are all second-generation cellular network standards that use TDMA.
- AMPS is the first-generation cellular network standard that uses FDMA instead of TDMA.
