ABSTRACT:-Wireless system is a technology which now popular in worldwide to help people and machines.

Wireless is a biggest market segment each of these services which are used in wireless make specific demands.

Wireless local area network at home and business to high speed internet access in rural areas. Consumers have

quickly wireless technologies in pursuit of simplicity, productivity and mobility.

The wireless systems are easily portable because elimination of cable reach the area within the plant

which increasing data quality, availability. Metropolitan area network which gives pool network t developing

application

Keywords: - WLANs, WANs, MANs, PAN, FWA, Broadcasting.

INTRODUCTION: - Wireless system is one of the best and big technical successes for scientific view but also in

terms of market and society. The wireless data transmission is more easy and compactable and also wireless

systems are easily portable. Wireless LANs (local area network) at home and business to high speed internet access

in rural areas. Wireless technologies is provides simplicity, mobility, portability. It is eliminating the need of cable,

because of cable hard to reach area within the plant. In recent time wireless computer network have also led to

change in working habits and mobility of workers.

a) Wireless sensor network monitor factories: - wireless link replace cable connection between computer and

keyboard.

b) Wireless positioning system monitor: - the location of trucks that have goods identification by RF.

REVIEW OF WIRELESS SYSTEM:- Aim of this research to study about the wireless systems and application of

wireless, because at that time wireless system and wireless network used n wide area and range. Point to point

technology provides wider coverage area and because of packet switched technology refers as common platform for

all users to access the internet MANs, LANs and WANs providing best read required network. Security and military

technologies are also created by wireless.

Wireless local area network provides the most significant and highly performance to the

internet because today life runs totally around the social network site.

SERVICES OF WIRELESS SYSTEM:-

1. WIRELESS LOCAL AREA NETWORK (WLANs):- Wireless local area network having a technology

for connecting multiple computers across short distances. It can be also useful for connecting fixed location

computer to the internet. LANs should be at least fast as the internet that they are connected. Its transmission

means between 700 Kbit/sec.

LANs are interconnected using of four basis configuration

=> Not really a specific topology

=>A workstation in a wireless LAN can be anywhere as long as it is within transmitting distance to an access point.

=> Several versions of IEEE 802.11 standard define the various forms of wireless systems.

(a) Bus topology : -

(b) Tree topology : -

(c) Star topology: -

ADVANTAGES: -

a) Inexpensive

b) Highly reliable

c) Easy to install and manage

d) Easy to expand ,well understood by user

e) Simple to configure and display, suitable for command

DISADVANTAGES:

a) Relies on a single point of failure

b) Required transmission power to cover all location in network

2. WIDE AREA NETWORK (WANs):- Wide area network is a network that covers large geographical

locations or areas usually to interconnection multiple local area networks. It transverses and receives a public

network using one f wan technologies.

WAN connection technologies are:

Point to point technologies:

a) Provides wider coverage area where a direct line of site not available.

b) Ability to divide the network zone

c) Required less transmission power.

Circuit switched technologies:

This work as usually turn down when data transfer is completed circuited. switched line are generally low speed

compared o point to point line .

Example: -DIAL-Up, ISDN

Packet switched technologies:

In this technology share a common platform as well as infrastructure between all providers and subscribers.

Example: - Frame relay, X25

3. METTROPOLIAN AREA NETWORK (MANs):- This network gives the opportunity to pool effort in

developing application .in MANs metropolitan stands for a network which control a world wide area with having

the interconnection between LANs and WANs. MANs is a Omni directional bus service . it is a first server fully

connected to ATM infrastructure.

a) Enhancement of hardware

b) Application and software development

4. PERSONAL AREA NETWORK: -Personal area network is uses when the coverage area becomes even

smaller than that of WLANs .PANs such networks are mostly called as simple “cable replacement”. wireless links

between computer and peripheral devices (printer, mouse) and similar application performed by PANs.

5. FIXED WIRELESS ACCESS: - Fixed wireless access systems can also be considered as a type of WLANs.

Mainly replacing the cable connection between the user and the system come along fixed wireless access.

6. BROADCASTING: -In this wireless service application information is transmitted to different possibly

manners and users.

a) The information is only sent in one direction

b) The transmitted information is the same for all users.

APPLICATION OF WIRELESS SYSTEM:-

a) Wireless systems pooling based media access protocol for use the smart adaptive antennas to increase the

signal strength.

b) Wireless LANs used for broadband in a fading environment to increase its performance.

c) An adaptive combiner for c channel interference reduced in multiuser indoor radio systems in wireless.

d) A media access layer (MAC) layer protocol for broadband packet wireless network in used interfacing area.

e) A new adaptive MAC layer protocol used in wireless network.

f) Wireless local area network provided the most significant and highly performance to the internet.

g) Wireless sensors network offers new possibilities of monitoring and controlling factories and even home

from remote site.

h) Military and security is also creating by use of ireless product.

RECOMMANDATION FOR LITRATURE:-

a) Local area network providing the connection across the short distance but which area it covers ,it gives

proper connection and best quality of network.

b) Wide area network covers a large geographical area so that interconnection between LANs and WANs is

accurate.

c) Metropolitan area network gives the opportunity to pool effort in developing application that all application

work and run in proper way.

d) Personal area network defines for a single user and personal consumer provider so the connection between

computer and peripheral device much lower rate and effective connection.

e) Fixed wireless access can be define the elimination of cable or wires of a system and user so the range

much wider between system and user.

f) Broadcasting of channel s same but it must be accurate and used by transmission and receiving at the same

time.

Technologies: -

-WiMax

-WI-Fi

CONCLUSION:- Wireless systems provide best service in today’s competitive environment. At these days

wireless system is need for the life and these systems are easily portable and simplicity having with much

availability. In recent time wireless computers network have also led to change in working habits and mobility f

workers. Identification f any target is detected with the help of radio frequency (RF) which comes along wireless

systems.

A number of standards for PANs have been developing by the IEEE 802.15 groups.
