Numeric

802.11/802.11b. A radio protocol that may be used by the Symbol Spectrum24 radio card. Symbol radio cards
that use the 802.11 protocol also have an ESS_ID.

A

Access Point. Access Point (AP) refers to Symbol’s Spectrum24 Ethernet Access Point. It is a piece of
communications equipment that manages communications between the host computer system and one or
more wireless mobile computers. An AP connects to a wired Ethernet LAN and acts as a bridge between
the Ethernet wired network and IEEE 802.11 interoperable radio-equipped mobile units, such as a mobile
computer. The AP allows a mobile user to roam freely through a facility while maintaining a seamless
connection to the wired network.
AirBEAM® Manager. AirBEAM® Manager is a comprehensive wireless network management system that
provides essential functions that are required to configure, monitor, upgrade and troubleshoot the
Spectrum24® wireless network and its components (including networked mobile computers). Some features
include event notification, access point configuration, diagnostics, statistical reports, auto-disco very,
wireless proxy agents and monitoring of access points and mobile units.
AirBEAM® Smart Client. AirBEAM® Smart Client is part of Symbol’s AirBEAM® suite, which also includes
AirBEAM® Safe and AirBEAM® Manager. The AirBEAM® Smart Client system uses the network accessible
host server to store software files that are to be downloaded to the mobile computers. The AirBEAM® Smart
Client provides the mobile computers with the “smarts” to request software from the host. It allows them to
request, download and install software, as well as to upload files and status data. The AirBEAM® Smart
Client uses the industry standard FTP or TFTP file transfer protocols to check the host system for updates,
and if necessary, to transfer updated software. Most often, AirBEAM® Smart Client is used with wireless
networks, but any TCP/IP connection can be used. For more information, refer to the AirBEAM® Smart
Windows® CE Client Product Reference Guide (p/n 72-63060-xx).

Aperture. The opening in an optical system defined by a lens or baffle that establishes the field of view.
API. An interface by means of which one software component communicates with or controls another. Usually
used to refer to services provided by one software component to another, usually via software interrupts or
function calls
