Appendix 3: WiFi Configuration Notes
Introduction
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 Mini Socket iWiFi supports the 802.11b/g wireless LAN communication
platform. It uses the iChip™ CO2128 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 Mini Socket iWiFi 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 Mini Socket iWiFi may be configured to put the WiFi chipset in Power
Save mode in conjunction with iChip’s inherent Power Save mode.
