3. Now-a-days the goal of many customers is to have PC
at one’s palm . To support such powerful systems we
need long range, high speed wireless network called 4G.

4. Generations
GenG

6. COMPARISON BETWEEN 3G AND 4G:
Technology 3G 4G
Frequency band 1.8 - 2.5GHz 2 - 8GHz
Bandwidth 5-20MHz 5-20MHz
Data rate Up to 2Mbps 100Mbps moving,
1GB stationary
Access W-CDMA VSF-OFCDM
VSFCDMA
FEC Turbo-codes Concatenated
Switching Circuit/Packet Packet

7. Convergence Services—seamless , high-reliable, quality
broadband communication ,ubiquitous-
connectivity.
Broadband Services---Low Cost.
---Wide Coverage Area.
---Wide Variety of Services Capability.

8.  LTE[Long Term Evolution]—UMTS(universal mobile
telecomm. Systems)
Objectives : Improving Efficiency.
Lowering Costs.
Improving Services.
Better integration with
other standards.
Aim of LTE : Download rate - 100mbps
Upload rate-50 mbps.

9.  WIMAX-[Worldwide Interoperability for Microwave Access]
Objective: Low Cost.
Low Expense Voice transport
and delivery of services.
Aim: Download data-rate 4 mbps.
Upload data-rate 14 mbps.

10.  Adaptive Modulation And Coding(AMC).
 Adaptive Hybrid ARQ.
Multi In-Multi Out And Orthogonal Frequency-Division
Multiplexing(MIMO and OFDM).
Open Distributed AD-HOC Wireless Network.

12. Flexible channel bandwidth—5 MHz to 20 Mhz.
(up to 40 MHz)
Developing of 3G applications: MMS(multimedia messaging
services).
Video chat.
Mobile T.V.
HDTV.

13. STRENGTHS: Strong position of telecommunication vendors.
Faster data transmissions .
Higher bit-rate .
Larger bandwidth.
Personalized multimedia communication tools.
WEAKNESS: No large user community .
Divergence between vendors and operators.
No full internet -- limited speed ,bandwidth
Highest cost to use and on infrastructure.

14. OPPORTUNITIES: Evolutionary approach.
Sophisticated commercialization would
encourage e-commerce and m-commerce.
Expected that consumers will replace
handsets with newer tech.
Desirable higher data capacity rates.
THREATS: Faster rate of growth and developments in other
region.
Since 3G is still in market ,it squeezes the market
competition in mobile industry.

16. 4G mobile phone technology promises faster communication
Speeds (100 megabits per second), capacity and diverse usage
formats. These formats would provide richer content and
support for other public networks such as optical fibre and wireless
local area networks.

17. Delivers true speeds without wires.
Faster -- more bandwidth.
Completely portable .
3 times faster than 3G .
4G is broadband technology that will give us richer ,pleasurable
internet experience.
