Improved performance over 2G, including: Improved capacity;

A high degree of service flexibility, including: Support of a wide range of services with maximum bit rates

above 2 Mbps and the possibility for multiple parallel services onone connection;

A fast and efficient packet-access scheme.

A high degree of operator flexibility, including: Efficient support of different deployment scenarios, including

hierarchical cell structure and hot-spot scenarios; Support of evolutionary technologies such as adaptive

antenna arrays and multi-user detection.

What is 3G?

The Third Generation of Telecommunication hardware standardsand general technology for mobile networking, superseding 2.5G

3G networks enable network operators to offer users services likewide-area wireless voice telephone, video calls, and broadbandwireless data, all in a mobile environment

Provides data rates up to 14.4 Mbps on the downlink and 5.8 Mbpson the uplink.

Based on the International Telecommunication Union (ITU) familyof standards under the IMT-2000

An organization called 3rd Generation Partnership Project (3GPP)has continued work by defining a mobile system that fulfills theIMT-2000 standard. This system is called Universal MobileTelecommunications System (UMTS).

Why 3G?Limitations of 2G

Voice centric

Designed mainly for telephony application Circuit-switched High BER (Bit Error Rate) Low data bit rate (< 14.4kbps)

Too many standards globally

GSM, CDMA, PDC, PHS etc.

Isolated networks MAP based IS-41 based Difficult to roam between these networks

3G Handsets availability Now that government has announced 3G

Policy,handset manufacturers are gearing up tolaunch 3G compatible phones at affordable price.

Huawei Technologies is planning sell 3G entry-level phone within $80 to $100.

LG

s KU250 3G phone is priced at $100.

Motorola has about three 3G models rangingfrom Rs 14,000 to Rs 19,000 (i.e. $350.-$475)

Why lower subscribers

Pricing.

Lack of awareness of its benefits.

The lower subscriber numbers are a testimonial to the factthat private players should be allotted spectrum at theearliest - after all, government is losing money by delaying3G auction and the ones who have been allotted spectrumarent able to market/position it to consumers

All said and done, government owned companies needserious (and aggressive) competition from private playersotherwise, expect a suboptimal and mediocre 3G story.

Ericsson is BSNL's strategic partner

for 3G roll-out Ericsson is using its WCDMA/HSPA technology to help

BSNL, India's largest telecom operator, achieve India'sbiggest simultaneous launch of 3G services to date, across11 leading cities. The commercial launch of much awaited3G services in India will allow consumers to experienceenriched communications including rich voice, video anddata services.

Ericsson is BSNL's strategic partner for 3G roll-out in over400 of these cities.The mammoth roll-out will also strengthen BSNL's positionas a leading player with a broad offering includingWireline, GSM Mobile, CDMA mobile, Internet, Broadband,Carrier service, MPLS-VPN, VSAT, VoIP services, IN

Services to Indian consumers.

Why delayed?

3G services were delayed because of thespectrum issues, licensing issues and auctionprocess. There is still not enough clarity on the

policy front and there are lot of questions to beanswered.

Will price-sensitive Indian consumers shift inlarge enough numbers to a 3G system? Whilethere's no doubt the market is low-value witheach customer yielding just Rs 400 a month tothe mobile phone companies (after deducting thelicensing revenue share), around 5 to 10 per centof customers pay monthly bills of more than Rs1,000 per month.

How fast exactly is 3G?

The data speed of 3G is determined based on acombination of various factors including :

Chip rate

Channel structure Power control Number of users in a cell Distance of user from cell User is moving or stationary Synchronization There is no clear definition of the speeds users can expect

from 3G equipment or providers. Thus customer using the3G service may not be able to point to a standard and saythat the speed it specifies are not being met.

90 Million 3G Subscribers In IndiaBy 2013?

According to a study by industry associationFederation of Indian Chambers of Commerceand Industry (FICCI) and telecom consultingfirm BDA, 3G revenues in India will reach $15.8billion or 46% of the total wireless revenue, by2013.

The 3G subscriber base is expected to reach 90

million in five years, accounting for 12% of thetotal telecom subscriber base of 746 million
