1.2 Wireless Basics
Wireless networking uses electromagnetic radio frequency waves to transmit and receive data.
Communication occurs by establishing radio links between the wireless access point and devices
configured to be part of the WLAN.

The 3e-523 incorporates 802.11 Wi-Fi standards, and FIPS 140-2 compliant security for wireless
communication.
communication.
802.11a - The IEEE 802.11a standard is an extension to 802.11 that applies to wireless LANs and
provides up to 54 Mbps in the 5 GHz band. Depending on radio design and RF channel issues 802.11a
devices can operation at rates between the 54 Mbps maximum and 6 Mbps. 802.11a uses an Orthogonal
Frequency Division Multiplexing (OFDM) encoding scheme rather than Frequency-Hopping Spread
Spectrum (FHSS) or Direct-Sequence Spread Spectrum (DSSS).

802.11b - The IEEE 802.11b compliant devices provide 11 Mbps transmission (with a fallback to 5.5, 2 and
1 Mbps depending on signal strength) in the 2.4 GHz band. 802.11b devices operate using
Direct-Sequence Spread Spectrum (DSSS) modulation techniques. Note that for the 3e-523E-900 this is
the only mode used, and controls to change this are not available in the configuration software.
