802.11b
The IEEE 802.11b standard, developed by the Wireless Ethernet
Compatibility Alliance (WECA) and ratified by IEEE, establishes a stable
standard for compatibility. A user with an 802.11b product can use any
brand of access point with any other brand of client hardware that is built
to the 802.11b standard for basic interconnection. 802.11b 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.
For wireless devices to communicate with the 3e-525A , they must
meet the following conditions:
• The wireless device and wireless access point must have
been configured to recognize each other using the SSID (a
unique ID assigned in setup so that the wireless device is
seen to be part of the network by the 3e-525A );
• Encryption and authentication capabilities and types en-
abled must conform; and
• If MAC filtering is used, the 3e-525A must be configured to
allow the wireless device’s MAC address to associate (com-
municate) with the 3e-525A wireless interface.
802.11g
Because 802.11g is backwards-compatible with 802.11b, it is a popular
component in LAN construction. 802.11g broadens 802.11b’s data rates
to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency
division multiplexing) technology. The dual functionality of 802.11b and
802.11g is preferable to use of 802.11b with 802.11a, as this would require
that you replace exisitng NICs with 802.11a/b NICs to ensure interoper-
ability. These are some of the considerations that were taken into account
in designing the 3e-525A .
Network Configuration
The 3e-525A is an access point with bridging setup capability:
• Access point/Gateway plus:
• Wireless bridging with choice of:
- Point-to-point setup
- Point-to-multipoint setup
- Repeater setup
Bridging actually has more choices, but the above choices are popular
and are discussed later in this user guide (Chapter 4).
