UMTS
Cdma2000
TD-SCDMA
LTE
Answer is Wrong!
Answer is Right!
The correct answer is D. LTE.
- UMTS (Universal Mobile Telecommunications System) is a 3G mobile cellular technology. It is the successor to GSM and is based on the GSM core network. UMTS uses W-CDMA (Wideband Code Division Multiple Access) for radio transmission.
- Cdma2000 is a 3G mobile cellular technology. It is the successor to CDMAOne and is based on the CDMAOne core network. Cdma2000 uses CDMA2000 (Code Division Multiple Access 2000) for radio transmission.
- TD-SCDMA (Time Division Synchronous Code Division Multiple Access) is a 3G mobile cellular technology. It is a time division duplex (TDD) system that uses CDMA for radio transmission.
- LTE (Long Term Evolution) is a 4G mobile cellular technology. It is not a 3G standard.
LTE is a more advanced technology than 3G. It offers higher data rates and lower latency. LTE is also more efficient than 3G, which means that it can support more users in the same area.
