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 Signalling

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 73) or provide physical access the serial port of the
