Appendix 5: WiFi Configuration Notes
Introduction
The AT+I programmer's manual includes full details for WiFi configuration. Please
visit the support section on Connect One's website to obtain the last version. The
following is a partial overview of WiFi related commands.
Wireless LAN stations operate in one of two modes: Infrastructure or Ad-Hoc.
In Infrastructure mode, wireless LAN stations connect to a wireless LAN Access
Point (AP), which acts as a hub. Wireless LAN stations may connect to each other
through the AP. If the AP is connected to LAN, it allows wireless LAN stations to
connect to other stations on the LAN. When a gateway is in place, it enables wireless
LAN stations to connect to systems across the gateway, as well.
In Ad-Hoc mode, two or more wireless LAN stations communicate directly with each
other.
The Nano WiReach supports the 802.11b/g wireless LAN communication platform. It
uses the iChip™ CO2144 communication controller chip and Marvell 88W8686 WiFi
chipset. It incorporates several dedicated AT+i configuration parameters to support
the wireless LAN environment. See the table below for a detailed list of WiFi
configuration parameters.

The Nano WiReach may also be configured to exploit WEP security. iChip supports
configuration of both 64-bit or 128-bit WEP keys.
In Infrastructure mode, Power Save mode is supported. When activated, Power Save
shuts down the station for a limited period of time, during which the Access Point
buffers incoming packets destined for the deactivated WiFi station. The station
periodically wakes up to retrieve all the buffered packets stored in the Access Point.
In this mode, total power consumption is lowered at the expense of higher response
latency. The Nano WiReach may be configured to put the WiFi chipset in Power Save
mode in conjunction with iChip's inherent Power Save mode.
