Appendix A - Wireless Basics 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.
Appendix A - Wireless Basics Where is wireless used? Wireless technology is expanding everywhere not just at home or ofice. People like the freedom of mobility and it’s becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.
