In general, the 802.11a cards will consistently maintain a

data rate, at any range, of 3 to 10 times higher than 802.11b

products. For example, if the range of an 802.11b product

at 11 Mbps is 100 feet in the given environment (before

backing off to 5.5 Mbps), the 802.11a PC cards, in the same

environment, may have backed off from 108 Mbps to 96

Mbps to 72 Mbps, but will still be over 6 times faster at that

distance than 802.11b (72 Mbps vs. 11 Mbps).

Again, keep in mind that all wireless LANs are highly sub-

ject to environment conditions and that the LAN’s perform-

ance in your environment may differ from the examples dis-

cussed.

802.11a Mode vs. 2X Mode

The Harmony 802.11a PC Card is capable of operating in

two modes: 802.11a Mode and 2X Mode. In 802.11a

Mode, the default mode, the maximum data rate is 54

Mbps and the card will be interoperable with other

802.11a-compliant products.

In order to experience 100 Mbps networking, it is necessary

to configure your Harmony 802.11a PC Card for Proxim’s

2X Mode (also referred to as Turbo Mode). In this mode,

the maximum data rate is 108 Mbps. When in 2X Mode,

the Harmony 802.11a PC Card is not interoperable with

other 802.11a products.

Refer to the Demo Kit Quick Start Guide for instructions

on configuring your Harmony 802.11a PC Card for 2X

Mode.
