COMPARISON BETWEEN 3G AND 4G:
1.8 - 2.5GHz
Up to 2Mbps
2 - 8GHz
Convergence Services—seamless , high-reliable, quality
broadband communication ,ubiquitousconnectivity.
Broadband Services---Low Cost.
---Wide Coverage Area.
---Wide Variety of Services Capability.
LTE[Long Term Evolution]—UMTS(universal mobile
Objectives : Improving Efficiency.
Better integration with
Aim of LTE : Download rate - 100mbps
Upload rate-50 mbps.
WIMAX-[Worldwide Interoperability for Microwave Access]
Objective: Low Cost.
Low Expense Voice transport
and delivery of services.
Aim: Download data-rate 46 mbps.
Upload data-rate 14 mbps.
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.
Flexible channel bandwidth—5 MHz to 20 Mhz.
(up to 40 MHz)
Developing of 3G applications: MMS(multimedia messaging
STRENGTHS: Strong position of telecommunication vendors.
Faster data transmissions .
Higher bit-rate .
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.
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
Since 3G is still in market ,it squeezes the market
competition in mobile industry.
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.
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
