1. --Forthcoming technology in wireless
communication

2. 4g technology: one
View
•4G is the short name for fourth-generation wireless, the stage of
mobile communications that will enable things like IP-based voice,
data, gaming services and high quality streamed multimedia on
portable devices with cable modem-like transmission speeds.

3. M  Mobile Multimedia
A  Anywhere
G  Global mobility solutions
I  Integrated Wireless
C  Customized Services

6.  4G can provide a 10 times
increase in data transfer
over 3G.
 This speed can be
achieved through
Orthogonal Frequency
Division Multiplexing
(OFDM).

7.  OFDM (ORTHOGONAL FREQUENCY DIVISION
MULTEPLEXING)
 SMART ANTENNAS
 MIMO

10. Switched Beam Antennas Adaptive Array
Antennas

13.  Support for interactive multimedia, voice, streaming video,
Internet, and other broadband services.
 IP based mobile system.
 High speed, high capacity, and low cost-per-bit
 Better spectral efficiency

14.  Expensive.
 Battery uses are more.
 Hard to implement
 Need complicated hardware.

15.  Virtual Presence
 Virtual Navigation
 Tele-Geo processing
 Crisis Management

16.  All totally the best way to help all users is to use 4G as the
next wireless system and in totally it is safety and secure for
public, this the need that demands the solution.
 Today’s wired society is going wireless and if it has problem,
4G is answer.

17.  There are some good reasons for 4G development and a
variety of current and evolving technologies to make 4G a
reality.
 Lesser the expensive of the system, the more people who will
want to own it.
