Implementation of all wireless internet services for 4G mobile communication system


Fourth generation (4G) mobile systems and services will mainly be characterized
by a horizontal communication model, where different access technologies such as
cellular, cordless, wireless local area network (WLAN), short-range connectivity,
and wired systems will be combined on a common platform to complement each
Other optimally for different service requirements and radio environments. To
access different wireless networks, multimode user terminals are essential. The
most promising way of implementing multimodal user terminals is to adopt the
software radio approach. The current software radio technology does not meet the
requirements of different wireless networks; because it is impossible to have just
one antenna and one LNA (Low Noise Amplifier) to serve the wide range of
frequency bands.
In this paper, I am implementing a novel idea using CI/OFDM (Carrier
Interferometry-OFDM) to access multiple networks using a wireless terminal.
The physical size of the wireless terminal proposed in the present work, will be
smaller than the terminal with software radio device, and enough memory can be
inserted in the terminal device to store software for all networks.

Plan of Work

Analyzing the proposed system
Obtaining the system model
Obtaining the mathematical model
Compose the coding using Matlab
Simulation of BER performance

Literature Survey

Willie W.Lu,”Next generation communication towards open wireless standard and software defined radio” IEEE 2008 IET International Conference on Wireless, Mobile and Multimedia Networks

To achieve high data rates in next generation communication systems beyond 3G up to 100 Mbps or more research focuses on the open distributed wireless communication system called ODWCS which is a new architecture for a wireless access system with distributed & smart antennas (MIMO), distributed processors and distributed controlling through software defined radio (SDR) which is supposed to take care of all types of mobility management for end to end quality of service with greater reliability. This paper contributes towards the importance of open communication platform with reconfiguring ability with the changing environment of the communication with the aid of software defined radio. SDR provides an efficient and comparatively inexpensive technique for multi-mode, multi-band, multi-functional communications with software upgrades. SDR technology and open standards promise to do for the wireless industry what the PC and object-oriented software and operating systems have done for the computer industry.

Mobile System Generations

First Generation (1G) mobile systems were designed to
offer a single service, i.e., speech.
Second Generation (2G) mobile systems were also
designed primarily to offer speech with a limited
capability to offer data at low rates.
Third Generation (3G) mobile systems are expected to
offer high-quality multi-media services and operate in
different environments.
3G systems are referred to as Universal Mobile
Telecommunications System (UMTS) in Europe and International
Mobile Telecommunications 2000 (IMT2000) worldwide.

An abbreviation for Fourth-Generation
A 4G system will be able to provide a comprehensive IP solution where voice, data, streamed, multimedia can be given to users on an ” Anytime, Anywhere ” basis, and at higher data rates than previous generations.


–Continuous in amplitude and time
–Variations in the signal –disrupts over long distances
Simplest type to wireless data
Average between 4,800 to 9,600 bps (bits per second)


Digital –consists of 1s and 0s
Digital signal:
1) Low level, 2) High level, 3) Rising edge
4) Falling edge

2G contd-

GSM (Global System for Mobile Communication)
Deployed in mid 1991 in Europe
Benefit from the ability to roam and switch carriers without replacing phones

IS-95 (CDMA)

Idea from military & Developed by Qualcomm
Using CDMA (Code Division Multiple Access) One Frequency all the time
Several transmitters to send information simultaneously over single communication channel

The 3G technology adds multimedia facilities to 2G phones by allowing video, audio, and graphics applications. Over 3G phones, you can watch streaming video or have video telephony.
3G networks deliver broadband capacity and support greater numbers of voice and data customers at lower incremental costs than 2G. Standards: - W-CDMA: Wideband Code Division Multiple Access - EVDO: Evolution-Data Optimized

A single family of compatible standards that can be used worldwide for all mobile applications.
Support for both packet-switched and circuit-switched data transmission.
Data rates up to 2 Mbps (depending on mobility).
High spectrum efficiency


The GSM is a circuit switched, connection oriented technology, where the end systems are dedicated for the entire call session. This causes inefficiency in usage of bandwidth and resources.
The GSM-enabled systems do not support high data rates.
They are unable to handle complex data such as video.


High bandwidth requirement.
High spectrum licensing fees.
Huge capital.


Also known as ‘Mobile Broadband everywhere’
Mobile Multimedia Communication
Anywhere, Anytime with Anyone
Global Mobility Support
Integrated Wireless Solution
Customized Personal Service
Theoretically, 4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1Gbps to a stationary device.
According to 4G Mobile Forum, by 2010 over $400 billion would be invested in 4G mobile projects.
In India, communication Minister Mr. Dayanidhi Maran, has announced a national centre of excellence to work in 4G arena.


Each node will be assigned a 4G-IP address (based on IPv6).
Formed by a permanent “home IP address” and a dynamic “care-of ” address that represents its actual location.
When a device (computer) in the Internet wants to communicate with another device (cell phone) in the wireless network, the computer will send a packet to the 4G-IP address of the cell phone targeting on its home address.
HOW 4G WORKS? contd

Then a directory server on the cell phone’s home network will forward this packet to the cell phone’s care-of address through a tunnel, mobile IP;
The idea is that the 4G-IP address (IPv6) can carry more information than the IP address (IPv4)
IPv6 means Internet Protocol Version 6 including 128 bits, which is 4 times more than 32bits IP address in IPv4. 32 bits IP address looks like this or 11011000.00100101.10000001.00001001 (32 bits).
The IP address in IPv6 version will be 4 times of IPv4; it looks like,,,
HOW 4G WORKS? contd
The first set of the IP address ( can be defined to be the “home address”. It just likes the normal IP address that we use for addressing in the Internet and network.
Second set of the IP address ( can be declared as the “care-of address”. It is the address set up for the communication from cell phones to computers
The third set of the IP address ( can be signed as a tunnel (mobile IP address). An agent, a directory server, between the cell phones and PC will use this mobile IP address to establish a channel to cell phones.
The last set of IP address ( can be local network address for virtual private network (VPN) sharing purpose.
4G Technology

OFDM (Orthogonal Frequency Division Multiplex)
Technology that transmits data simultaneously over a large number of channels at different frequencies, enable to send an large data
Using in IEEE 802.11a & g, Hiper-LAN II and IEEE 820.16 BWA

4G Technology

4G Application

5G is a completed wireless communication with almost no limitation; somehow people called it REAL wireless world

5G wireless system is only theory and not real


4G is ”Anytime Anywhere”

4G is still at research stage, available after 2010 (?)...

... While the impact of 3G is still uncertain!

Employing the discussed techniques, 4G has a significant potential for capacity improvements over 3G systems.

Companies developing 4G technology investing about $400 billion for its projects.
