Wireless devices enable wireless communication between devices in a limited area, through spread spectrum or OFDM modulation at radio frequencies above 2.4 GHz. Commonly used Wireless devices include Access points, Routers, Bridges, Hubs, Hotspots, Antennas, Wireless NICs which connect through Bluetooth, USB,PCI and PCMCIA.

802.11 standards govern the operation of Wireless networks. Some standards include 802.11a, 802.11b, 802.11g and 802.11n; the communication is made secure using WEP, WPA or WP2 specifications. Access point forms the base station in a wireless network; wireless clients such as Laptops, Desktops and PDAs connect to the access point through a chain of wireless devices.

Popular Manufacturers like NETGEAR, Cisco Systems, 3COM, and D-Link provide outstanding quality of Post-sales Technical support for a wide range of their products. In 2007, the wireless LAN hardware revenue neared $1 billion, a gigantic 40% increase in 2004; the growth in the number of shipped units increased by 131%.

For a Consumer, a computer with Wireless communication capability is mandatory; the rest of the infrastructure is dependant on the coverage area, signal strength, operating frequency, data transfer rate and the bandwidth involved in the communication. The newest wireless devices support most standards including the 802.11n which incorporates OFDM and spatial multiplexing, operates at 2.4 MHz and has a data transfer rate of 100-200 Mbps.
