 Wireless Technology 
 First generation (1G) 
 Second generation (2G) 
 Need for 3G 
 Literature survey 
 Standards of 3G 
 CDMA2000 evolution to 3G 
 3GPP family technologies evolution 
 Features of 3G 
 Applications of 3G 
 Advantages & Disadvantages 
 Fourth generation (4G) 
 Fifth generation (5G)
WIRELESS TECHNOLOGY 
 The word wireless is dictionary defined as 
“having no wires.” 
 In networking technology , wireless means 
any computer where there is no physical 
wired connection between sender and 
receiver. 
 Radio waves or microwaves used to 
maintain communications.
FIRST GENERATION(1G) 
 FEATURES: 
 Speed up to 2.4kbps. 
 Voice calls in 1 country. 
 Used Analog Signal.
SECOND GENERATION(2G) 
 Based on GSM. 
 Launched in1991. 
 Digital signals. 
 Data speed up to 64kbps. 
 Text messages, picture 
messages, MMS. 
 Better quality and capacity.
DRAWBACKS OF 2G 
 GSM does not support high data rates 
 Inefficient usage of bandwidth and 
resources 
 Unable to handle complex data 
 Reduced range of sound 
 Weaker digital signal
NEED FOR 3G! 
 80% of wireless subscribers 
 Demand for high speed data services 
 Interest in multimedia services 
 To remove drawbacks of 2g
