3. INTRODUCTION OF WIRELESS
NETWORK
 Wireless is a term used to describe
telecommunications in which electromagnetic
waves (rather than some form of wire) carry the
signal over part or all of the communication path.
 The word wireless is dictionary defined as
"having no wires". In networking terminology,
wireless is the term used to describe any
computer network where there is no physical
wired connection between sender and receiver,
but rather the network is connected by radio
waves and/or microwaves to maintain
communications. Wireless networking utilizes
specific equipment such as NICs, APs

4. 1G
TECHNOLOG
Y-1G refers to the first generation of wireless
telephone technology(mobile
telecommunications) which was first introduced
in 1980s and completed in early 1990s.
It's Speed was up to 2.4kbps.
It allows the voice calls in 1 country.
1G network use Analog Signal.
AMPS(Advanced Mobile Phone System) was
first launched in USA in 1G mobile systems.

5. LIMITATIONS-
 Battery life is poor.
 Poor voice quality.
 No Security system.
 Phones are large in size.
 Capacity is limited.
 Poor Handoff Reliability

6. 2G
TECHNOLOGY
-
2G technology refers to the 2nd
generation which is based on GSM.
It was launched in Finland by
Radiolinja in the year 1991.
2G network use digital signals.
It’s data speed was up to 64kbps.

7. FEATURES
INCLUDES-
 It enables services such as text
messages, picture messages and
MMS(Multi Media Message).
 It provides better quality and
