XBee® Wi-Fi RF Modules

1. Overview

The XBee® Wi-Fi RF module provides wireless connectivity to end-point devices in

802.11 bgn networks. Using the 802.11 feature set, these modules are interoperable

with other 802.11 bgn devices, including devices from other vendors. With XBee, users

can have their 802.11 bgn network up and running in a matter of minutes.

The XBee® Wi-Fi modules are compatible with other devices that use 802.11 bgn

technology. These include Digi external 802.11x devices like the ConnectPort products

and the Digi Connect Wi-SP, as well as embedded products like the ConnectCore series

and Digi Connect series of products. More information on these Digi products can be
