Installing the Proxim 802.11a Adapters / Drivers
Using the Proxim 802.11a Harmony to Monitor “2X”
Networks
The Proxim Harmony 802.11a adapter card used by the Sniffer software
supports a proprietary extension of the 802.11a standard called 2X (or,
occasionally, Turbo). Essentially, this extension allows 802.11a networks to
operate at twice the rates stated by the 802.11a specification (for example,
instead of the upper limit of 54 Mbps stated for the 802.11a specification, the
2X extension theoretically allows for an upper limit of 108 Mbps).
If you want to use the Proxim Harmony to monitor a network which has
implemented the 2X extension, be sure to enable the 2X/Turbo mode for the
adapter before starting the Sniffer software. Enable the 2X/Turbo mode in
either the Advanced tab of the Connection Properties dialog box, or in the
vendor-supplied configuration utility for the Proxim Harmony. See the
procedures in Using the Proxim 802.11a Adapter as a Normal Network
Adapter on page 72 for information on how to access this tab (as well as other
ways to set configuration options for the Proxim Harmony).
