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).
