This chapter provides an overview of Wireless networking.
Wireless Networking Overview
The WGR614 router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 
802.11 standard for wireless LANs (WLANs) and a product update will bring the WGR614 into 
conformance to the 802.11g standard when it is ratified. On an 802.11b or g wireless link, data is 
encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the 
unlicensed radio spectrum at 2.5GHz. The maximum data rate for the wireless link is 11 Mbps, but 
it will automatically back down from 11 Mbps to 5.5, 2, and 1 Mbps when the radio signal is weak 
or when interference is detected. The 802.11g auto rate sensing rates are 1, 2, 5.5, 6, 9, 12, 18, 24, 
36, 48, and 54 Mbps.
The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet 
Compatibility Alliance (WECA, see 
http://www.wi-fi.net
), an industry standard group promoting 
interoperability among 802.11 devices. The 802.11 standard offers two methods for configuring a 
wireless network - ad hoc and infrastructure.
Infrastructure Mode
With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This 
mode provides wireless connectivity to multiple wireless network devices within a fixed range or 
area of coverage, interacting with wireless nodes via an antenna.
