Installing the Modem
This section will help you to successfully integrate the Boomer-III
OEM Modem into your custom application.
When integrating a wireless modem, internal connections and
placements are critical to a successful implementation. Specific
attention must be paid to the following support mechanisms:

attention must be paid to the following support mechanisms:
Mechanical mounting
Serial interface and control
Antenna connection
Regulated power supply
Application software
Desense control
The OEM wireless modem is well suited for mobile or fixed
applications. Ruggedised and capable of operating in extreme
environments, the modem can provide communications for a wide
variety of products.

Handheld Portable Terminal Use
Without question, handheld designs produce the most hostile
environment for an integrated modem. A handheld device, such as a
portable terminal, is typically battery powered, subjected to
temperature extremes, and designed to be physically robust.
When designing portable devices, you must consider the following
issues:

DC power noise levels on the host/terminal interface
Minimum operating voltage levels
Shutdown procedures

Mechanical design for drop, vibration, dust, salt, and liquid spill
Note: Regarding the mechanical design, the Boomer-III OEM modem
is designed assuming that the host/terminal controls these conditions.

Fixed Mount Usage
Fixed-mount usage eliminates most of the mechanical constraints of
handheld designs, although the requirements still apply. Fixed-mount
units are sometimes AC-line powered and require filtering to eliminate
