Introduction

3G stands for third generation of mobile phones and

it enables increased data-handling rates and high

speed bandwidth. Due to this technology, 3G mobile

phones offer features like :

Video conference calling

Web browsing

Broad band (speed of 2 Mbps) e mail

FAX

PROTOCOLS

A. Universal Mobile Telecommunications

System (UMTS)

The UMTS transport networks handle high data

traffic. The WCDMA air interface is selected for

paired frequency bands (FDD operation) and

TDCDMA (TDD operation) for unpaired spectrum.

HSPA is an enhanced version of 3G UMTS.

EM Spectrum for UMTS is 1885-2025 MHz for

future systems and 1980-2010 MHz and 2170-2200

MHz for satellite portion of UMTS.

Protocols UnderUMTS

Wideband-Code Division Multiple Access (W-

CDMA) :

Radio channels are 5MHz wide. Supports two basic

modes of duplex: FDD and TDD. It is designed to

offer speeds of at least 144kbps to users in fast-

moving vehicles and up to 2Mbps to stationary

users.

High Speed Packet Access (HSPA) :

It is collection of High Speed Downlink Packet Access

(HSDPA) and High Speed Uplink Packet Access

(HSUPA) to provide increased performance with data

rates up to 14 Mbit/s in downlink and 5.8 Mbit/s in

uplink.

Time Division Code Division Multiple Access:

It uses time division duplexing. HSPA enchantments

are used under it. In Europe it is an alterative toWCDMA

Time Division Synchronous Code Division

Multiple Access :It is an alternate to TD-CDMA as it uses synchronous

spread spectrum across multiple time slots.

Timeslots are dynamically adjusted for downlink and

uplink, for more easy accommodation of asymmetric

traffic requirements than FDD schemes.

Super-Charged network:UMTS network in which the Super-Charger

mechanism is being used to optimize mobility

management signaling.

B. CDMA2000:

It is a hybrid 2.5G/3G technology of mobiletelecommunications standards that use CDMA, for

digital radio, to send voice, data, and signaling data

between mobile phones and cell sites. CDMA2000

standard is created to support IS-95 evolution.CDMA2000 enables the largest coverage area using

450 MHz, 700 MHz, 800 MHz, 900 MHz, 1700 MHz,

1800 MHz, 1900 MHz, and 2100 MHz frequency

bands and extended base station coveragesolutions.

Protocols Under CDMA2000

Evolution-Data Optimized (Ev-DO) :It is for the wireless transmission of data through

radio signals, broadband Internet access. Up to 4.9

Mbit/s per carrier. Supports efficiently services with

asymmetric download and upload requirements.

Evolution-Data/Voice (Ev-DV) :

It supports downlink data rates up to 3.1 Mbit/s and

uplink data rates of up to 1.8 Mbit/s. EV-DV can also

support concurrent operation of legacy 1x voice

users, 1x data users, and high speed EV-DV data

users within the same radio channel.13

4G : FUTUREOF 3G

4G is also known as evolution beyond 3G in wireless

communication.

It will be providing higher network capacities for

simultaneous users.

At least 100 Mbit/s data rates for physically moving

user wrt station and up to 1Gbit/s for fixed positions.

R

eal time audio/video, HDT

V video facilities, highspeed data transfer etc.

Capability of easy interaction with existing older

standards.
