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 different types of wireless networks:Wireless Local Area Network (WLAN), andWireless 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 has become so popular in recent years that almost everyone is using it, whether it's for home, office, business, D-Link has a wireless solution for it. D-Link R12 User Manual 115

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 different 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 has become so popular in recent years that almost everyone is using it, whether it’s for home, office, business,
D-Link has a wireless solution for it.
