                                                                                                        Preface



Important             Due to the nature of wireless communications, transmission and reception of data
                      can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be
Notice                totally lost. Although significant delays or losses of data are rare when wireless
                      devices such as the Sierra Wireless modem are used in a normal manner with a
                      well-constructed network, the Sierra Wireless modem should not be used in
                      situations where failure to transmit or receive data could result in damage of any
                      kind to the user or any other party, including but not limited to personal injury,
                      death, or loss of property. Sierra Wireless accepts no responsibility for damages
                      of any kind resulting from delays or errors in data transmitted or received using
                      the Sierra Wireless modem, or for failure of the Sierra Wireless modem to
                      transmit or receive such data.


Safety and            Do not operate the Sierra Wireless modem in areas where blasting is in progress,
                      where explosive atmospheres may be present, near medical equipment, near life
Hazards
                      support equipment, or any equipment which may be susceptible to any form of
                      radio interference. In such areas, the Sierra Wireless modem MUST BE
                      POWERED OFF. The Sierra Wireless modem can transmit signals that could
                      interfere with this equipment.
                      Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is
                      on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE
                      POWERED OFF. When operating, the Sierra Wireless modem can transmit
                      signals that could interfere with various onboard systems.

                      Note: Some airlines may permit the use of cellular phones while the aircraft is on the
                      ground and the door is open. Sierra Wireless modems may be used at this time.


                      The driver or operator of any vehicle should not operate the Sierra Wireless
                      modem while in control of a vehicle. Doing so will detract from the driver or
                      operator's control and operation of that vehicle. In some states and provinces,
                      operating such communications devices while in control of a vehicle is an offence.

                                                                                          RF Specifications



                     Antenna and cabling
                     When selecting the antenna and cable, it is critical to RF performance to match
                     antenna gain and cable loss.

                     Choosing the correct antenna and cabling
                     When matching antennas and cabling:
                     •   The antenna (and associated circuitry) should have a nominal impedance of
                         50  with a return loss of better than 10 dB across each frequency band of
                         operation.
                     •   The system gain value affects both radiated power and regulatory (FCC, IC,
                         CE, etc.) test results.

                     Designing custom antennas
                     Consider the following points when designing custom antennas:
                     •   A skilled RF engineer should do the development to ensure that the RF
                         performance is maintained.
                     •   If both CDMA and UMTS modules will be installed in the same platform, you
                         may want to develop separate antennas for maximum performance.

                     Determining the antenna’s location
                     When deciding where to put the antennas:
                     •   Antenna location may affect RF performance. Although the module is
                         shielded to prevent interference in most applications, the placement of the
                         antenna is still very important — if the host device is insufficiently shielded,
                         high levels of broadband or spurious noise can degrade the module’s perfor-
                         mance.
                     •   Connecting cables between the module and the antenna must have 50 
                         impedance. If the impedance of the module is mismatched, RF performance
                         is reduced significantly.
                     •   Antenna cables should be routed, if possible, away from noise sources
                         (switching power supplies, LCD assemblies, etc.). If the cables are near the
                         noise sources, the noise may be coupled into the RF cable and into the
                         antenna.

                     •   For LTE / UMTS bands, use the AT command !RXDEN=0 to disable receive
                         diversity or !RXDEN=1 to enable receive diversity.
                     •   For CDMA bands, use the AT command !DIVERSITY to enable or disable
                         receive diversity.

                     Note: A diversity antenna is used to improve connection quality and reliability through
                     redundancy. Because two antennas may experience difference interference effects (signal
                     distortion, delay, etc.), when one antenna receives a degraded signal, the other may not be
                     similarly affected.

                        Ground connection
                        When connecting the module to system ground:
                        •   Prevent noise leakage by establishing a very good ground connection to the
                            module through the host connector.
                        •   Connect to system ground using the two mounting holes at the top of the
                            module.
                        •   Minimize ground noise leakage into the RF.
                            Depending on the host board design, noise could potentially be coupled to
                            the module from the host board. This is mainly an issue for host designs that
                            have signals traveling along the length of the module, or circuitry operating at
                            both ends of the module interconnects.


                        Interference and sensitivity
                        Several interference sources can affect the module’s RF performance
                        (RF desense). Common sources include power supply noise and device-
                        generated RF.
                        RF desense can be addressed through a combination of mitigation techniques
                        (Methods to mitigate decreased Rx performance on page 15) and radiated
                        sensitivity measurement (Radiated sensitivity measurement on page 16).

                        Note: The MC7355 is based on ZIF (Zero Intermediate Frequency) technologies. When
                        performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate
                        Frequency) components from the module to consider.



                        Interference from other wireless devices
                        Wireless devices operating inside the host device can cause interference that
                        affects the module.
                        To determine the most suitable locations for antennas on your host device,
                        evaluate each wireless device’s radio system, considering the following:
                        •   Any harmonics, sub-harmonics, or cross-products of signals generated by
                            wireless devices that fall in the module’s Rx range may cause spurious
                            response, resulting in decreased Rx performance.
                        •   The Tx power and corresponding broadband noise of other wireless devices
                            may overload or increase the noise floor of the module’s receiver, resulting in
                            Rx desense.
                        The severity of this interference depends on the closeness of the other antennas
                        to the module’s antenna. To determine suitable locations for each wireless
                        device’s antenna, thoroughly evaluate your host device’s design.


                        Host-generated RF interference
                        All electronic computing devices generate RF interference that can negatively
                        affect the receive sensitivity of the module.

                                                                                      RF Specifications


                     Proximity of host electronics to the antenna in wireless devices can contribute to
                     decreased Rx performance. Components that are most likely to cause this
                     include:
                     •   Microprocessor and memory
                     •   Display panel and display drivers
                     •   Switching-mode power supplies


                     Device-generated RF interference
                     The module can cause interference with other devices. Wireless devices such as
                     AirPrime embedded modules transmit in bursts (pulse transients) for set durations
                     (RF burst frequencies). Hearing aids and speakers convert these burst
                     frequencies into audible frequencies, resulting in audible noise.


                     Methods to mitigate decreased Rx performance
                     It is important to investigate sources of localized interference early in the design
                     cycle. To reduce the effect of device-generated RF on Rx performance:
                     •   Put the antenna as far as possible from sources of interference. The
                         drawback is that the module may be less convenient to use.
                     •   Shield the host device. The module itself is well shielded to avoid external
                         interference. However, the antenna cannot be shielded for obvious reasons.
                         In most instances, it is necessary to employ shielding on the components of
                         the host device (such as the main processor and parallel bus) that have the
                         highest RF emissions.
                     •   Filter out unwanted high-order harmonic energy by using discrete filtering on
                         low frequency lines.
                     •   Form shielding layers around high-speed clock traces by using multi-layer
                         PCBs.
                     •   Route antenna cables away from noise sources.


                     Radiated Spurious Emissions (RSE)
                     When designing an antenna for use with AirPrime embedded modules, the host
                     device with an AirPrime embedded module must satisfy the radiated spurious
                     emission (RSE) test cases described in:
                     •   (CDMA) Refer to CDMA standards for receive-only mode, and local
                         regulatory bodies for transmit mode (transmitter is operating).
                     Note that antenna impedance affects radiated emissions, which must be
                     compared against the conducted 50-ohm emissions baseline. (AirPrime
                     embedded modules meet the 50-ohm conducted emissions requirement.)

                     Note: GSM spurious emissions are most likely to have RSE issues, but in general, RSE
                     requirements must be met on all models with user-designed antennas.

                        Radiated sensitivity measurement
                        A wireless host device contains many noise sources that contribute to a reduction
                        in Rx performance.
                        To determine the extent of any receiver performance desensitization due to self-
                        generated noise in the host device, over-the-air (OTA) or radiated testing is
                        required. This testing can be performed by Sierra Wireless or you can use your
                        own OTA test chamber for in-house testing.

                                 Important notice
                                 Because of the nature of wireless communications, transmission and
                                 reception of data can never be guaranteed. Data may be delayed,
                                 corrupted (i.e., have errors) or be totally lost. Although significant
                                 delays or losses of data are rare when wireless devices such as the
                                 Sierra Wireless modem are used in a normal manner with a well-
                                 constructed network, the Sierra Wireless modem should not be used
                                 in situations where failure to transmit or receive data could result in
                                 damage of any kind to the user or any other party, including but not
                                 limited to personal injury, death, or loss of property. Sierra Wireless
                                 and its affiliates accept no responsibility for damages of any kind
                                 resulting from delays or errors in data transmitted or received using
                                 the Sierra Wireless modem, or for failure of the Sierra Wireless
                                 modem to transmit or receive such data.


                                 Safety and hazards
                                 Do not operate your MC7355 modem:
                                 •   In areas where blasting is in progress

                        •   Where explosive atmospheres may be present including refuelling points, fuel
                            depots, and chemical plants
                        •   Near medical equipment, life support equipment, or any equipment which
                            may be susceptible to any form of radio interference. In such areas, the
                            MC7355 modem MUST BE POWERED OFF. Otherwise, the MC7355
                            modem can transmit signals that could interfere with this equipment.
                        In an aircraft, the MC7355 modem MUST BE POWERED OFF. Otherwise, the
                        MC7355 modem can transmit signals that could interfere with various onboard
                        systems and may be dangerous to the operation of the aircraft or disrupt the
                        cellular network. Use of a cellular phone in an aircraft is illegal in some
                        jurisdictions. Failure to observe this instruction may lead to suspension or denial
                        of cellular telephone services to the offender, or legal action or both.
                        Some airlines may permit the use of cellular phones while the aircraft is on the
                        ground and the door is open. The MC7355 modem may be used normally at this
                        time.
