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.
