What is Wireless?

Wireless or Wi-Fi

technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio

frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or o ce network.

How does wireless work?

Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless

technology has restrictions as to how you can access the network. You must be within the wireless network range area to be able

to connect your computer. There are two dierent types of wireless networks Wireless Local Area Network (WLAN), and Wireless

Personal Area Network (WPAN).

Wireless Local Area Network (WLAN)

In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small

antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point, the signal

can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing

plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues.

Wireless Personal Area Network (WPAN)

Bluetooth

is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30

feet away.

Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as much

power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices

that operate on batteries.
