Wireless Computer Networks and Internet Access
Bluetooth – Bluetooth is a popular name for the 802.15 wireless networking standard, which is used primarily for creating small personal area networks (PANs). They link devices (up to eight) within a 10-meter area using low-power, radio-based communication and can transmit up to 722 Kbps in the 2.4-GHz band. Phones, pagers, computers, printers and computing devices can each use Bluetooth.
Wi-Fi – The 802.11 set of standards for wireless LANs and wireless Internet access is also known as Wi-Fi. The original standard that was adopted was 801.11b, which transmits up to 11 Mbps in the unlicensed 2.4-GHz band and has an effective distance of 30-50 meters.
Hotspots – These typically consist of access points that provide wireless Internet access in a public place like a hotel, an airport, a cafe, a campus. Sometimes they are free, sometimes they aren’t. Businesses use wi-fi networks to provide low-cost wireless LANs and Internet access.
Wi-Max – (Worldwide Interoperability for Microwave Access) is a wireless industry coalition dedicated to the advancement of IEEE 802.16 standards for broadband wireless access (BWA) networks. WiMAX supports mobile, nomadic and fixed wireless applications.
