the modem and host/terminal. Ensure that the following hardware
integration issues are evaluated:
RF Immunity
RF transmissions of the modem do not interfere with operation of the
host/terminal.
Electrical Signaling
Power sources and interface are functionally compatible between the
host/terminal and the modem.
Physical Parameters
Physical configuration of the modem inside the host/terminal provides
adequate ventilation, mounting, shielding, and grounding.
Antenna Performance
Integrated antenna system meets the required ERP specifications,
VSWR specifications, antenna propagation patterns and any applicable
network operator requirements.
ESD Requirements
Host/terminal design protects the modem from ESD.
RF Re-radiation
Host/terminal does not allow spurious emissions in excess of 60dBc, as
caused by carrier re-radiation (for 3V/m fields).
Desense and EMI
Any host/terminal in which the modem is integrated generates some
EMI (electromagnetic interference), which tends to desensitise the
modem’s ability to receive at certain frequencies.
Wavenet can provide a facility for testing the amount of desense that
your modem experiences while in a host/terminal. Specifically, modem
receiver sensitivity is recorded while operating with the host/terminal
under test. For this test, you provide an integrated product, including
antenna, power supply and any peripherals. Wavenet Technology then
produces a test graph that reports the amount of desense. All desense
testing is generally performed at Wavenet Technology’s facilities.
To prepare for the desense test, provide Wavenet with hardware to
generate EMI that is representative of the final product, including the
cables, power supplies, and other peripheral devices. The host/terminal
must supply the modem the appropriate power requirements. The
host/terminal hardware must be running its CPU, LEDs, and serial
ports, etc (if so configured).
You must supply either the pass-through mode functionality (“Enabler
Functions” on page 74) or provide physical access the serial port of the
