the modem and host. Ensure that the following hardware integration
issues are evaluated:
RF Immunity
RF transmissions of the modem do not interfere with operation of the
host.
Electrical Signaling
Power sources and interface are functionally compatible between the
host and the modem.
Physical Parameters
Physical configuration of the modem inside the host provides adequate
ventilation, mounting, shielding, and grounding.
Antenna Performance
Integrated antenna system meets the required ERP specifications,
VSWR specifications, and antenna propagation patterns.
ESD Requirements
Host design protects the modem from ESD. (FCC Limit –47dBc)
RF Re-radiation
Host does not allow spurious emissions in excess of 60dBc, as caused
by carrier re-radiation (for 3V/m fields).
Desense and EMI
Any host 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 platform. Specifically, modem
receiver sensitivity is recorded while operating with the host 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 must
supply the modem the appropriate power requirements. The host
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 67) or provide physical access the serial port of the
modem . The ability to turn on and off the various circuits in the host
