When was 3G technology introduced?

Launch of 3G The first global pre-commercial launch of the 3G network was in Japan by NTT Docomo in 1998, and it was branded as FOMA. The first commercial launch of the technology happened on October 1, 2001- also by NTT Docomo in Japan.

What are the features of CDMA?

Salient Features of CDMA Individual conversations are encoded with a pseudo-random digital sequence and then transmitted using a wide frequency range. CDMA consistently provides better capacity for voice and data communications, allowing more subscribers to connect at any given time.

What are the parts of 3G network architecture Mcq?

There are three major parts to a 3G mobile network:

• A Radio Access Network (RAN). This is a hierarchical arrangement of cell towers and base stations.
• A core network (usually IP) tying the RAN to the 3G service network.
• A service network reached through the core network.

What are the features of GSM?

Listed below are the features of GSM that account for its popularity and wide acceptance.
