The AirBEAM Smart product allows specially designed software packages to be transferred between a host server 
and a vehicle computer. Before transfer, AirBEAM Smart checks and compares package version, so that only 
updated packages are loaded. 

AirBEAM Smart resides on the vehicle computer and allows it to request, download and install software, as well as 
to upload files and status data. Both download and upload of files can be accomplished in a single communications 
session. The ability to transfer software over a wireless network can greatly reduce the logistical efforts of client 
software management.

In an AirBEAM Smart system, a network-accessible host server acts as the storage point for the software transfer. 
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.

In a typical distributed AirBEAM system, software to be transferred is organized into packages. In general, an 
AirBEAM package is simply a set of files that are assigned attributes both as an entire package and as individual 
component files. The package is assigned a version number and the transfer occurs when an updated version is 
available.

An AirBEAM package can optionally contain developer-specified logic to be used to install the package. Installation 
logic is typically used to update client device flash images or radio firmware. Examples of common AirBEAM 
packages would include packages for custom client application software, radio firmware and AirBEAM Smart Client 
software.

Once these packages are built, they are installed on the host server for retrieval by the vehicle computer. The 
AirBEAM Package Builder is a utility used to define, generate and install AirBEAM packages to a server. The 
packages are then loaded from the server onto a client device equipped with an AirBEAM Smart Client executable.

For detailed instructions on how to define, generate and install AirBEAM packages to the server, refer to the 
AirBEAM Package Builder Product Reference Guide, p/n 72-55769-xx.

The AirBEAM Smart Client is installed on the vehicle computer. It is configured with the server access information, 
the names of the packages to be downloaded and other controlling parameters. When the AirBEAM Smart Client is 
launched, the device connects to the specified FTP server and checks the packages it is configured to look for. If 
the package version was updated, the client requests the transfer. 

The AirBEAM Smart Client is a licensed software product. The AirBEAM Smart Client's version synchronization 
functionality is enabled through a license key file that is stored on the vehicle computer. The license key file can be 
built into AirBEAM Smart Client's image, or downloaded in a special AirBEAM package.

The AirBEAM license key file contains a unique key and a customer specific banner that is displayed when the 
AirBEAM Smart Client version synchronization logic is invoked.

Connect the vehicle computer to a host computer using the Development Cable.
