7925G/7925G-EX/7926 IP PHONES



The 7925G, 7925G-EX, and 7926 models are 802.11a/b/g wireless handsets. They are hermetically sealed to avoid contamination by dust, liquids, and so on The exterior is coated in a rubber casing to aid in handling and provide some drop protection.


These handsets meet U.S. military 810F standards. Each of the models supports Bluetooth 2.0 with Enhanced Data Rate (EDR) hands-free profile. Also built in is a button for push-to-talk functionality that can be enabled via XML application integration.


One of the more interesting additions to these handsets is the introduction of an on-board Java virtual machine, which allows the handset to run Java MIDlets locally. This allows for customized content/information to be presented to the 2-inch color screen.


So, why choose one model over the others? Up to this point, they each seem relatively similar in form and function. The differences are somewhat based on the intended use of the phone and the environment in which it will be used. The figure below shows the 7925G model.



The 7925G is the general-purpose handset model and is the most widely deployed of the three. The 7925G-EX is ruggedized and built for hazardous environments. Its bright yellow color makes it stand out in any environment. It is Atmospheres Explosibles (ATEX) Zone 2 certified for use around hazardous gases, chemicals, and other potentially explosive environments.


The figure below shows the 7925G-EX handset sitting in an optional speakerphone/ charger cradle (compatible with all three models).



The 7926G has a built-in 2D image barcode scanner. This is useful in any environment wherein inventory/assets need to be tracked. The 2D barcode scanner is not a laser-based scanner. It uses light emitting diodes (LEDs) to illuminate the target barcode and takes a picture of it, which is decoded by the phone.


The resulting information is then relayed to a customer/partner developed backend system application for processing/storage. The 7926G looks identical to the 7925G in almost every way. As mentioned, the only real difference is the barcode scanner situated in the top of the handset. The figure below shows a top-down view of the handset to detail the barcode scanner.
