LOGO INTRODUCTION
WHAT IS WIRELESS ?
The word wireless in dictionary is defined “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 and
Routers in place of wires (copper or optical fiber).

INTRODUCTION
WHAT IS EMERGING CELLULAR TECHNOLOGY ? .
Mobile operators use the radio spectrum to provide their servic.
Spectrum is a scarce resource and has been allocated as such. It has
traditionally been shared by a number of industries, including
broadcasting, mobile communications and the military. However, this
reduced the total bandwidth available to each user, affecting the
quality of service. Introduced in the 1970s, cellular technology
allowed for the division of geographical areas (into cells), rather than
frequencies, leading to a more efficient use of the radio spectrum.

LOGO 1G TECHNOLOGY
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 upto 2.4kbps.
It allows the voice calls in 1 country.

LOGO 2GTECHNOLOGY
 2G technology refers to the 2nd
generation which is
based on GSM and global system for communication system.
 It was launched in Finland in the year 1991.
 2G network use digital signals.
 It’s data speed was upto 64kbps.
 2G having the narrowband bandwidth.
 Its divided into 2 parts
 1 Time division multiple access in this type TDMA allow
the division of signal into time slot. TDMA like as a frequency
signal.
 2 Code division multiple access in this type we use the
unique code. CDMA allocate each user a special code to
communicate

LOGO FEATURE&DRAWBACKS OF2G
Features Includes:
 It enables services such as text messages,
picture messages and MMS (multi media message).
 It provides better quality and capacity .
Drawbacks:-
2G requires strong digital signals
to help mobile phones work. If there
is no network coverage in any specific
area , digital signals would weak.
 These systems are unable to
handle complex data such as Videos.

LOGO 4G TECHNOLOGY
1. LTE - LTE, an abbreviation for Long-Term Evolution, commonly marketed
as 4G LTE, is a standard for wireless communication of high-speed data for
mobile phones and data terminals. It is based on the GSM/EDGE and UMTS
/HSPA network .
2. Wi-MAX - WiMAX (Worldwide Interoperability for Microwave Access) is
a wireless communications standard designed to provide 30 to 40 megabit-
per-second data rates,[1] with the 2011 update providing up to 1 Gbit/s[1]
for fixed stations. The name "WiMAX" was created by the WiMAX Forum,
which was formed in June 2001 to promote conformity and interoperability
of the standard. The forum describes WiMAX as "a standards-based
technology enabling the delivery of last mile wireless broadband access as
an alternative to cable and DSL".[2]

7G TECNOLOGY
• The 7G will be the most advance generation in mobile
communication network. It is like the 6G for global coverage but it will
also define the satellite functions for mobile communication. But in
7G, there will be some research on demanding issues like the use of
mobile phone during moving condition from one country to another
country, because satellite is also moving in constant speed and in specific
orbit, the standards and protocols for cellular to satellite system and for
satellite to satellite communication system. The dream of 7G can only be
true when all standards and protocols are defined. May be this
is possible in next generation after 7G and can be named as7.5G.There is
another way, is direct HD video broad casting for news gathering
likewise. This can be the best solution of cost on lower level user X.
