3. 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.

4. FIRST GENERATION(1G)
 FEATURES:
 Speed up to 2.4kbps.
 Voice calls in 1 country.
 Used Analog Signal.

6. SECOND GENERATION(2G)
 Based on GSM.
 Launched in1991.
 Digital signals.
 Data speed up to 64kbps.
 Text messages, picture
messages, MMS.
 Better quality and capacity.

7. 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

8. NEED FOR 3G!
