Spectrum24 Wireless LAN Adapter Users Guide 1

Chapter 1 Introduction

The LA-4121 PC Card and LA-4123 PCI adapter are Spectrum24 directsequence (DS) products. Spectrum24 DS is a spread spectrum network operating between 2.4 and 2.5 GHz. Spread spectrum communication provides a high-capacity network within large or small environments. Spectrum24 DS products provide a high-capacity network using multiple access points within large or small environments.

• Spectrum24 bridging architecture allows communication between wired network devices and mobile devices.

•Spectrum24 products support the IEEE 802.11b and WiFi compliance specifications. This open architecture allows Spectrum24 devices to communicate with wireless devices from other manufacturers that conform to the same specifications.

• Spectrum24 products allow mobile devices to roam throughout large facilities while remaining connected to the network.

• Spectrum24 antenna diversity allows adapters to alternate between antennas with the best reception, increasing overall performance.

• Spectrum24 products allow the establishment of ad-hoc wireless workgroup networks.

• Spectrum24 products are protocol-independent, allowing mobile devices to communicate with a wide range of servers, hosts and systems.

Introduction

2 Spectrum24 Wireless LAN Adapter Users Guide

Spectrum24 Wireless LAN Adapter Users Guide 3

Chapter 2 About the Spectrum24 Wireless

LAN Adapter

The Spectrum24 Wireless LAN (WLAN) adapter allows PC Card slot and PCI adapter slot-equipped host systems to configure, connect to and establish a Spectrum24 network.

Features Include:

• Multiple operating mode options for access point or peer-to-peer associations

• Low-power operation for battery-powered devices with PC Card slots

•Standard NDIS (Network Driver Interface Specification) drivers

• Windows 98SE, ME, 2000, XP and CE (PPC 2002) operating system support

• WEP, Kerberos, EAP-TLS and KeyGuard data security

• Power management [Continuously Aware Mode (CAM) and Power Save

Polling (PSP)].

About the Spectrum24 Wireless LAN Adapter

4 Spectrum24 Wireless LAN Adapter Users Guide

2.1 Operating Modes

The Symbol Mobile Companion utility installs with the Spectrum24 Windows driver. Use Mobile Companion to select the operational mode, ESSID, encryption algorithm and power consumption mode used with the Spectrum24 adapter.

Spectrum24 LA-4121 PC Cards and LA-4123 PCI adapters support the following operational modes:

• In Infrastructure mode, the adapter interoperates with an access point

(AP). The adapter can roam freely between access point cells in the network or transmit and receive across subnets. Mobile Units (MUs) appear as network nodes to other devices in the network. Infrastructure is the adapter default mode.

• Select Ad Hoc mode to form peer-to-peer networks without access

points. Use Ad Hoc to create networks where needed within established Spectrum24 network coverage areas. The MU starting the Ad Hoc network (the first Spectrum24 adapter transmitting a beacon) determines the channel and data rate used for the other Spectrum24 adapters within the network using the same ESSID.

About the Spectrum24 Wireless LAN Adapter

Spectrum24 Wireless LAN Adapter Users Guide 5

2.2 11 Mbps Operation

The Spectrum24 Wireless LAN adapter supports a maximum 11Mbps data rate. The adapter automatically shifts to a 5.5, 2 or 1Mbps data rate when unable to maintain a high quality connection at 11Mbps. When the WLAN adapter detects improved signal strength, it shifts to an increased data rate, up to the maximum 11Mbps.

The following factors can dynamically alter the data rate:

• signal strength between the access point and Spectrum24 adapter

• the ratio of good transmitted packets to attempted transmitted packets that fall below a threshold

• the MU finds a higher transmit rate with another AP.

Physical obstructions and numerous devices operating in close proximity to one another negatively impact the ability to maintain an 11Mbps access point association.

About the Spectrum24 Wireless LAN Adapter

6 Spectrum24 Wireless LAN Adapter Users Guide

2.3 Power Management

LA-4121 PC Cards support the Continuously Aware (CAM) and Power Save Polling (PSP) power-management modes. CAM requires the radio to remain on. Symbol does not recommend CAM for battery powered devices.

The PCI version of the Spectrum24 WLAN adapter (model LA-4123) functions in CAM only.

PSP mode allows the PC Card to conserve power by suspending communication for short periods of time while still associated with an AP. The AP saves data for transmission to the PC Card when it wakes at given intervals. When the PC Card wakes to check for data, it switches back into CAM until it is ready to suspend communications again.

The PSP performance index, which varies from Excellent to Acceptable, allows users to specify how often the PC Card wakes to check for data. The Excellent PSP performance index provides the quickest response time (shortest sleep interval), while the Adequate PSP performance index provides efficient power consumption (longest sleep interval). Use the Adequate performance index when periods of PC Card inactivity are anticipated or when using a battery for a notebook computer.

Use the Symbol Mobile Companion Power Property Page utility to manually set the PSP performance index.

2.4 Plug and Play

The PCI version of the Spectrum24 WLAN adapter (model LA-4123) supports Plug and Play systems. This allows a computer to recognize the PCI adapter, and configure the hardware interrupt, memory and device recognition addresses. This feature requires less user interaction and minimizes hardware conflicts.

2.5 Spectrum24 PC Card LED Descriptions

The LA-4121 PC Card LED illuminates during connection or data transfer to indicate the functional status of the PC Card.

The LA-4123 PCI adapter supports various plane antennas with various LED behavior. Refer to the documentation shipped with the antenna for a description of LED behavior.
