Introduction of wireless technology:-

The term ”wireless” has become a generic and all encompassing word used to explain the communication in which electromagnetic waves bring a signal whole communication way or path. Wireless networking also solution of the consumer which electronic devices and application can be plug into Microsoft is doing on a range of wireless technology to enable a robust set of user scenarios for LAN, PAN; WAN etc.Bluetooth is wireless technology which is support by any window. The common example of wireless is given below:-

· Cellular telephone
· Global positioning system
· wireless computer system
· Wireless telephone, satellite television e.t.c.
·
At the last fifty years, wireless communication industry experience drastic changes driven by many technology.

Use of wireless technology:-

Wireless communication is the communication which transfers the information over a distance with out the use of wire. It means without using electronic conductor. The distance may be in short or few meter and t may be far or million of kilometer like radio communication. Wireless communication is generally happened branch of telecommunication various types of wireless are two way radio, cellular telephones, personal digital assistant and wireless networking. The wireless technology have some example are such as GPS unit, wireless computer, mice, satellite, headset, keyboard, cordless phone, television e.t.c. wireless communication is to provide a backup communication link in case of normal network down. Wireless communication is used to link portable or temporary workstation. Wireless communication is easy to implementation and cabling or normal network is difficult to work. Wireless communication is used in mobile also by user. Wireless can via communication like radio frequency, microwave connection, infrared e.t.c.


Importance:-

Wireless communication is importance because of faster which used to transfer the data one place to another place without using cable or physical thing.
Wireless communication has become popular today world. It has no secret of wireless technology has become strong communication to entertains and give education across the planet of the world .today’s business will not run with out wireless technology.

Advantage:-

1. Increase efficiency:-communication is faster transfer the data within the minutes/per second to the receiver.
2. It is rarely out of touch:-we should not have to carry cable or adaptors to access the network.
3. More flexibility and mobility for uses:-all wireless pc is based of office which easily worker can be access network without disturb.
4. Lower cost:-it can be get wireless network in not high price.
5. Easily to install:-it is easy to install and maintains the wireless communication.
6. Involve reduced time to revenue:-many companies can generate revenue in less time through the wireless and we can work in online in within one two hours.
7. Service by broadband access extension:-broadband communications provide the wireless communication to the customers.

Disadvantage:-

1. The main problems are spectrum which is limited for available for consumers.
2. Reining spectrum is use maximum potential, spread. It is present to improved performance of spectrum technology.
3. It operated only for a limited period of time.
4. Radio equipment many affect the system through model to model security is less improved.
5. For ling distance wireless can not directly access to the wireless device.
6. Large number of devices which is which is being of a low power are transmitting.
