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).
