The document discusses the third generation (3G) of mobile telecommunications technology. 3G networks were introduced in 1998 and provide higher data rates and non-backward compatible transmission compared to previous generations. 3G offers advantages like more bandwidth, security, reliability and rich multimedia services, but also has disadvantages such as expensive licensing fees, infrastructure costs, and large phone sizes.

2. THIRD GENERATION
 3G, short form of third
generation, is the third
generation of mobile
telecommunications
technology
 A NEW GENERATION OF CELLULAR
STANDARDS HAS APPEARED
APPROXIMATELY EVERY TENTH YEAR
SINCE 1G SYSTEMS WERE
INTRODUCED IN 1981/1982. EACH
GENERATION IS CHARACTERIZED BY
NEW FREQUENCY BANDS, HIGHER
DATA RATES AND NON–BACKWARD-
COMPATIBLE TRANSMISSION
TECHNOLOGY. THE FIRST 3G
NETWORKS WERE INTRODUCED IN
1998 AND FOURTH GENERATION
"4G" NETWORKS IN 2008.

4. ADVANTAGES OF 3G
MORE BANDWIDTH,SECURITY AND
RELIABILITY
INTER PORTABILITY BETWEEN SERVICE
PROVIDERS
HIGH DATA SERVICES
RICH MULTIMEDIA SERVICES
NEW RADIO SPECTRUM TO RELIEVE
OVERCROWDING IN EXISTING SYSTEM

5. DISADVANTAGES OF 3G
 EXPENSIVE INPUT FEES FOR THE 3G SERVICES
LICENSES.
 NUMEROUS DIFFERENCES IN THE LICENSING
TERMS
 IT IS A CHALLENGE TO BUILD THE NECESSARY
INFRASTRUTURE FOR 3G
 EXPENSES OF 3G PHONES
 LARGE CELL PHONES
