Wireless Network: A Reflection Of Latest Trend
The power of communication amongst computers is equally important as that of power
of computers to process data, and by the impact of these powers information age has been revolutionized. This communication is responsible for the proliferation of computer networks.
Few major objectives of a computer network are information sharing, resources sharing (both software and hardware) and sharing of processing load.
Wireless communication falls under category of recent trends in the computer and communication industries. The radio waves in a wireless network are used instead of cables, and thus enhance the functionality of computing devices. Laptop users are much helped with wireless networking, since it is of great use to them while moving from one location to the other throughout the day.
Fixed wireless systems and mobile wireless systems are classifications of Wireless networks, where a little or no mobility of the equipment related to the wireless network is supported by a fixed wireless system.
A local area network can be configured by use of wireless network for getting rid of the headache of laying cables. The mobility of the equipment is supported by mobile wireless systems that enable the user to access information from anywhere and at any time. The personal digital assistants (PDAs), smart phones and pager with Internet access are few of multiple equipments used in the mobile wireless systems.
The radio waves or pulsing infrared lights are modulated to communicate wireless networks. The stationary transceivers are the intermediates to link wireless networking router to the wired network infrastructure.
Analog cellular, digital cellular, mobile radio networks, Cellular Digital Packet Data (CDPD), satellite, microwave systems, personal communication services (PCS) and local multipoint distribution systems (LMDS) are Wireless communication technologies utilized in wireless networks.
The wide availability of modems and analog cellular services makes analog cellular technology the most popular methods for wireless data communications, although the data rates supported by analog cellular technology are low.

Further elaboration to wireless network depends on their features and uses, they are:
Wireless PAN: Expanded as wireless personal area network; popularly known as a personal area network because a small geographical area is covered by it. Bluetooth is one such example of the WPAN, since connectivity of Bluetooth is limited only to an area of 10mts and thus proving to be a wireless personal area connectivity provider.
Wireless LAN: Expanded as wireless local area network supporting local area connectivity and covering a larger area than PAN.
Wireless MAN: Expanded as Wireless metropolitan area network and is spread in a metropolitan area covering a wider area than when compared to PAN and LAN.
Wireless WAN: Expanded as wireless wide area network and thus a covers a wide area. The nodes are connected perfectly with one another in wireless wide area network.
Mobile networks: The development of mobile smart phones initiates this network, which is to hold computer data with transferring abilities along with talking.
