Chapter 7: Configuring Communications

Cisco 802.11b DS SS PC Card Radio

Infrastructure Mode

When this parameter is set to Yes , the netpad operates in Infrastructure mode,

passing data through an access point—terminals cannot communicate directly with

other terminals in the network. If this parameter is set to No, the netpad operates in

“ad hoc” or “peer-to-peer” mode, passing data directly to other terminals—an access

point is not required. The default setting is Ye s.

Power Save Mode

The value assigned to this parameter determines the operating method the netpad

uses to conserve power. The default setting is Fast PSP.

CAM (Constantly Awake Mode) keeps the Cisco radio (TRX7441) powered up

continuously ensuring quicker message response. This mode is generally recom-

mended for desktop computers and devices using AC power.

Fast PSP (Fast Power Save Protocol), enables the netpad radio to switch between

Max PSP mode and CAM, depending on network traffic. The netpad radio switches

to CAM when retrieving a large number of packets and then switches to Max PSP

once the packets have been received. This mode is recommended where power con-

sumption is a concern but greater throughput than that allowed by Max PSP is

required. This is the default setting.

Max PSP (Maximum Power Save Protocol) powers the Cisco radio on and off

based on a time algorithm. Packets are retrieved only when the radio is scheduled to

be ‘on’. When the time expires, the radio turns off for the required time and then

turns back on again to retrieve more data. This mode is recommended where power

consumption is a significant concern.

Network Security Type

This parameter allows you to specify the type of 802.1X authentication that your

netpad will use. The default setting is None.

None disables 802.1X authentication.

LEAP enables LEAP authentication. LEAP is an authentication protocol that is pro-

prietary to Cisco and is designed to operate with Cisco access points. It is encapsu-

lated in an EAP (Extensible Authentication Protocol) packet used in conjunction

with the 802.1X standard to authenticate users at the MAC layer. The 802.1X stan-
