Wireless Networking Overview
The WGR614 router conforms to the Institute of Electrical and Electronics Engineers
(IEEE)
802.11 standard for wireless LAN
s (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.

To comply with FCC RF exposure compliance requirements, the antenna(s) used for this transmitter must 
be installed to provide a separation distance of at leaset 20 cm from all persons and must not be co-located 
ro operating in conjunction with any other antenna or transmitter. No change to the antenna or the device 
is permitted. Any change to the antenna or the device could result in the device exceeding the RF 
exposure requirements and void user's authority to operate the device.
