Appendix A - Wireless Basics
How does wireless work?
Wireless works similarly to how cordless phones work, through radio signals that 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 dierent 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, university 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. This makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other
devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, oce, business,
D-Link has a wireless solution for it.
