Wireless

The Institute of Electrical and Electronics Engineers (IEEE) an organization that defines industry-wide standards in the fields of electrics and computing has set guidelines or standards for wireless networking commonly called the wireless fidelity (WI-FI) standard.

Basic of wireless Networking:

For the distribution of data, the wireless network standard uses cellular radio signals or links to provides network connectivity to PCs and laptop through a transmitter/receiver unit (transceiver), generally known as an access point or wireless access point (WAP). WAP transmit and receiver signals to and from wireless network adapters.

Following are vital factors of it:

1) Weather condition between satellite and PC may reduce the power of the signal in a network because of the interface caused by induced electromagnetic waves due to cloud collision. This distorts the signals, which in turn affects the transmission of the signal over a network.

2) Security

3) Speed

• Hardware Requirement of a wireless Network:

Wirelesses networking capability of one form or another are built into many modern computing devices. Infrared transceiver ports have been made standardized computers, wireless Ethernet and Bluetooth capabilities are increasingly becoming popular as integrated components, or can easily be added by using peripheral component interconnect (PCI) or personal computer memory card International Association (PCMCIA) add-on cards.

• Wireless Access Point (WAP):

WAP is a device that sends and receives data signals that are used to establish a connection between two devices in a network. WAP is also referred to as a transceiver because it is used to transmit and receive data signals. A transceiver enables a user to connect two or more wireless devices and communicate with other users. WAP also acts as the point interconnection between WLAN.

    WAP can be divided into two types, hardware access point and software access point. Hardware access point is to define as a physical device used to establish a connection between two devices and software access point is defined as computers that include a wireless network interface card.
