The image below demonstrates such a setup. This is commonly setup to allow resources such as printers and files to be shared. In infrastructure mode all your traffic passes through a wireless access point and can be thought of as a wired network without cables.

Out of the 7 layers of the ISO Model (refer to image below), 802.11, like the other 802.x standards, centers around the Physical and Data link layer. Any application, operating system or protocol should work as well on a Wi-Fi LAN as it did on an Ethernet LAN.Īn 802.11b wireless network adapter can operate on two modes, Ad-Hoc or Infrastructure. In 1999 they amended the specifications to add two more speeds, 5.5 and 11Mbps. The IEEE published 802.11 in 1997 to make it the first globally approved wireless LAN standard. This allows you to surf the Internet at broadband speeds when connected to an access point or in ad hoc mode. Backward compatible with 802.11, 802.11b runs on the 2.4 GHz band and is capable of working at speeds of up to 11Mbps. Wi-Fi (Wireless Fidelity), or 802.11b, is an IEEE standard for wireless Local Area Networks. Although it has the capability of interconnecting up to 8 devices to form a small LAN, with a low bandwidth of about 700KB/sec and a range of about 30 feet it cannot really be considered as an honorable networking protocol. Bluetooth is more suited for connecting two point-to-point devices, whereas Wi-Fi is an IEEE standard intended for networking. It is more of a wireless substitute for connecting devices such as digital cameras, PDAs and mobile phones with each other or a desktop computer. 802.11g has improved on the performance of 802.11b and is backward compatible.īluetooth was invented to get rid of wires and can be used to create a Personal Area Network (PAN). Because of its proven track record and relatively inexpensive hardware, 802.11b has emerged as a favorite amongst SOHO users. It has since grown and 802.11a and g have been released and are going strong. The introduction of 802.11b was one of the first major steps towards the expansion of wireless networking – the jump to speeds of up to 11mbps (in reality you would however achieve something like 6mbps) contributed significantly to this.
