Wireless Networking Basics

B-1

The MP101 player conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 
standard for wireless LANs (WLANs). On an 802.11 wireless link, data is encoded using 
direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio 
spectrum at 2.4 GHz. The maximum data rate for the 802.11b wireless link is 11 Mbps, but it will 
automatically back down from 11 Mbps when the radio signal is weak or when interference is 
detected. 

The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet 
Compatibility Alliance (WECA, see 

), 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.

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. 

In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet 
data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple access 
points via a wired Ethernet backbone can further extend the wireless network coverage. As a 
mobile computing device moves out of the range of one access point, it moves into the range of 
another. As a result, wireless clients can freely roam from one access point domain to another and 
still maintain seamless network connection.
