oversees or behind enemy lines easily and quickly and was more reliable. Since then wireless

networks have continued to develop and its uses have significantly grown. Cellular phones are
part of huge wireless network systems. Sending information over seas is only possible through

wireless network systems using satellites and other signals to communicate across the world.
People and businesses use wireless networks to send and share data quickly whether it be in a

small office building or across the world.

Using radio waves to keep computers connected, a wireless network is the new way of
networking rather than relying on older copper line connections. Wireless networks allow to

eliminate messy cables. Wireless connections offer more mobility ,Wireless networks in terms of

internet connections, are typically slower than those that are directly connected through an
Ethernet cable. Type of security for wireless networks is WPA which stands for Wi-Fi Protected

Access. WPA provides more security to wireless networks than a WEP (Wireless Equivalency
Privacy) security set up does. The use of firewalls will help with security breaches which can

help to fix security problems in some wireless networks that are more vulnerable. The vision of
wireless communications supporting information exchange between people or devices is the

communications frontier of the next few decades, and much of it already exists in some form.

Wireless networks will connect palmtop, laptop, and desktop computers anywhere within an
office building or campus, as well as from the corner cafe. Wireless entertainment will permeate

the home and any place that people congregate. Video teleconferencing will take place between

buildings that are blocks or continents apart, Wireless video will enable remote classrooms,
remote training facilities, and remote hospitals anywhere in the world.

Wireless sensors have an enormous range of both commercial and military applications.
Commercial applications include monitoring of fire hazards, toxic waste sites, stress and strain in

buildings and bridges, carbon dioxide movement, and the spread of chemicals and gasses at a
disaster site. These wireless sensors self-configure into a network to process and interpret sensor

measurements and then convey this information to a centralized control location. Military

applications include identification and tracking of enemy targets, detection of chemical and
biological attacks, support of unmanned robotic vehicles, and counter terrorism.wireless

networks enable distributed control systems with remote devices, sensors, and actuators linked
together via wireless communication channels. Such systems in turn enable automated highways,

mobile robots, and easily reconfigurable industrial automation.
