3. INTRODUCTION
WHAT IS WIRELESS ?
The word wireless is dictionary 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 fibre).

4. 0G TECHNOLOGY(0G – 0.5G)
Mobile radio telephone systems preceded modern cellular
mobile telephony technology. Since they were the
predecessors of the first generation of cellular telephones,
these systems are sometimes referred to as 0G (zero
generation) systems.
It operate on 160 MHz VHF band using frequency
modulation on 160 -162 MHz for the mobile unit and 168-
170MHz for base stations.
0.5G is a group of technologies with improved feature than
the basic 0G technologies
The raw signaling rate is 19.2 kbps, and with Reed-
Solomon coding the effective data arte is 14.4 kbps full duplex
before control overhead.

5. 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.

12. 3G TECHNOLOGY
 High- Speed Downlink Packet Access(HSDPA) is a
packet-based data service in W-CDMA downlink with
data transmission up to 8-10 Mbit/s over a 5MHz
bandwidth in WCDMA downlink.
 Its implementations includes Adaptive Modulation and
Coding (AMC)
 Multiple-Input Multiple-Output (MIMO), Hybrid
Automatic Request (HARQ), fast cell search, and
advanced receiver design.

13. High Speed Uplink Packet Access (HSUPA) is a UMTS /
WCDMA uplink evolution technology, directly related to
HSDPA and the two are complimentary to one another.
HSUPA will enhance advanced person-to -person data
applications with higher and symmetric data rates.
It will initially boost the UMTS / WCDMA uplink up to
1.4Mbps and in later releases up to 5.8Mbps.

The earth image satellite system contains the weather
information as extra service for mobile users.

28. 7G TECHNOLOGY
Any two different satellite systems are necessary for
handoff/roaming when mobile users moving from one
country to another. This kind of handoff/roaming is space
handoff/roaming.

7.5G :
It provides the very high speed of peak download and peak upload of
data rate.
Here space time block codes are used to view the high definition of
video broadcasting.
Within a second we can download the five films that is 20 GB files and
upload the 15 GB files or any datum.
Therefore it also navigates the satellite networks techniques, hence
using the OFDM methodology and FEC for the speed of
communication process.
It is possible technique only when achieve the higher bandwidth and
improves the satellite cell sensitivity with its signal fidelity.
