1. Production Applications
The OEM wireless modem is well suited for mobile and fixed applications. The
wireless modem enables user to send/receive data anytime anywhere, and can
provide communications for a wide variety of products
1.1 Portable Terminal Use
Portable designs produce good environment for an integrated modem. The
portable terminal is typically battery powered, subject to temperature extremes,
and designed to be physically strong. When designing portable device, user
needs to pay attention to the following issue:
- DC power noise levels on the host interface
- Minimum operating voltage levels
- Device internal ambient temperature
- Antenna gain and proximity to user
- Mechanical design for drop, vibration, dust, salt and liquid spill.
Note : Regarding this last point, CNI-803D modem is designed on the assumption that
the host device will control these conditions
1.2 Fixed Mount Usage
Fixed-mount usage eliminates most of the mechanical constraints of handheld designs.
The core requirement applies, but fixed usage does not present any special conditions
to address.
