There are four type of Generation developed and they as follows.
History of Wireless Technology
First Generation (1G)
Second Generation (2G)
Third Generation (3G)
Fourth Generation (4G)

• Ultra High Speed Data Transmission
• From 1 Mbps to 1 Gbps• Orthogonal Frequency Division
Multiplexing (OFDM)
Fourth Generation (4G)

Fourth Generation (4G)
• 4G will change the way we work, live and play.
• Cheap end user costs, fast, always on, reliable doing.
• Some people view 3G as a stop gap until the real 4G network arrives, something which is due around 2010 and will impact every one, every where.
• 4G will provide unconceivable amount of bandwidth to the palm of a user.
• Will make world Dynamic, Fast, Easier to Access.

• Matching current Local Area Network speeds, 4G networks will provide 100 MBps on the move. This is enough for studio quality video, multi channel surround sound and much more.
• 4G will be based in OFDM (Orthogonal Frequency Division Multiplexing)
- the next generation in access technologies.
• Some possible IEEE standards for the 4G system are 802.20
“Based on OFDM Technology from 2005 till today”

Fourth Generation (4G)1. Services:
-Higher Capacity, - Completely IP-Oriented, - Multimedia High Data Rate Transfer
2. Standard - Single Standard
3. Data Bandwidth- Higher than 100 Mbps
4. Multiplexing- OFDM
5. Core Network- Internet
