PrefaceRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 3Important NoticeDue 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 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 HazardsDo not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life 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.Limitation of LiabilityThe information in this manual is subject to change without notice and does not represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its affiliates aggregate liability arising under or in connection with the Sierra Wireless product, regardless of the number of events, occurrences, or claims giving rise to liability, be in excess of the price paid by the purchaser for the Sierra Wireless product.

Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 1922: Technology OverviewLTELTE (Long Term Evolution) is a 4th-generation wireless standard. The 3GPP Release 8 specification outlines the features and requirements.Key features include.•Peak data rate:·100 Mbps DL within 20 MHz bandwidth(Peak DL data rate in 10 MHz bandwidth: 70 Mbps (approx.) for Cat 3 device)·50 Mbps UL within 20 MHz bandwidthActual throughput is dependent on the network configuration, bandwidth assigned to the UE, the number of users, and RF sig-nal conditions.•Up to 200 active users in a cell (5 MHz)•Less than 5 ms user-plane latency•Supported bandwidths: 5 MHz / 10 MHz•Spectrum flexibility: 1.4–20 MHz (3–20 MHz in future F/W release)•Enhanced support for end-to-end QOS•Physical layer uses:·DL: OFDMA (Orthogonal Frequency Division Multiple Access).Modulation: QPSK, 16QAM, and 64QAM·UL: Single Carrier FDMA (single carrier modulation and orthogonal frequency multiplexing)Modulation: QPSK, 16QAM•MIMO (Multi-Input Multi-Output) antenna supportCDMA1xEV-DO1xEV-DO is backwards compatible to both 1X and IS-95A/B standards. However, 1xEV-DO represents an evolutionary enhancement, specifically designed and optimized for high-speed wireless data access. This was driven by fundamental differences between voice and data traffic characteristics.

Product Technical Specification & Customer Design Guidelines20 Proprietary and Confidential - Contents subject to change 2400074eHRPD (Enhanced High Rate Packet Data) is an enhancement of 1xEV-DO that enables LTE to CDMA handover.To optimize for data, there are some fundamental characteristics and differences between 1X and 1xEV-DO, including:•The network has dedicated spectrum (1.25 MHz) for data traffic using 1xEV-DO standard, so resources don’t compete with 1X data/voice (hybrid mode used to monitor 1X carriers)•BTS always transmits at maximum available power•Each user receives data from only one base station at a time (no forward link soft handoff)•1xEV-DO lets each user use 100% of available resources, while dynamically allocating time resources among users for maximum efficiency•1xEV-DO uses time-division multiplexing of users on forward link (slots assigned for packet transmission)•Forward link supports higher order modulation (QPSK, 8-PSK and 16-QAM)•Reverse link (1xEV-DO Revision A) supports higher order modulation (8-PSK)•Mobile supports dynamic channel estimation using measured S/N to set the highest rate it can decode (uses Data Rate Control channel to communicate to network access point)•Mobiles can support Rx diversity for S/N enhancements particularly in multi-path/fading environments1X and IS-95AThe type of data connection made at any given time depends on the services available from the carrier in the given coverage area. If 1X packet services are not available, the modem connects using circuit-switched data over IS-95A technology. The modem automatically selects the fastest connection mode available when a data call is connecting.When roaming, the modem does not automatically change connection modes. If the modem connects using 1X and then roams outside of the packet service area, the connection is dropped. To resume data communication, a new connection using IS-95A has to be created. Similarly, an IS-95A call established in one area does not automatically transition to 1X when the unit enters the 3G coverage area.

If a longer distance is required because of the host device design, use a shielded wire assembly — connect one end as close as possible to the SIM connector and the other end as close as possible to the module connector. The shielded assembly may help shield the SIM interface from system noise.•Reduce crosstalk on the USIM_DATA line to reduce the risk of failures during GCF approval testing.•Avoid routing the USIM_CLK and USIM_DATA lines in parallel over distances 2 cm — cross-coupling of these lines can cause failures.•3GPP has stringent requirements for I / O rise time (<1 µs), signal level limits, and noise immunity — consider this carefully when developing your PCB layout.·Keep signal rise time <1 µs — keep USIM signals as short as possible, and keep very low capacitance traces on the USIM_DATA and USIM_CLK signals. High capacitance increases signal rise time, potentially causing your device to fail certification tests.•Add external pull-up resistors (15 k–30 k), if required, between the USIM_DATA and USIM_PWR lines to optimize the signal rise time.•VCC line should be decoupled close to the SIM socket.•SIM is specified to run up to 5 MHz (SIM clock rate). Take note of this speed in the placement and routing of the SIM signals and connectors.•You must decide whether additional ESD protection is required for your product, as it is dependent on the application, mechanical enclosure, and SIM connector design. The SIM pins will require additional ESD protection if they are exposed to high ESD levels (i.e. can be touched by a user).•Putting an optional decoupling capacitor at USIM_PWR near the SIM socket is recommended — the longer the trace length (impedance) from the socket to the module, the greater the capacitance requirement to meet compliance tests.•Putting an optional series capacitor and resistor termination (to ground) at USIM_CLK at the SIM socket to reduce EMI and increase signal integrity is recommended if the trace length between the SIM socket and module is long — 47 pF and 50  resistor are recommended.•Test your first prototype host hardware with a Comprion IT3 SIM test device at a suitable testing facility.

Electrical SpecificationsRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 33Control interface (Signals)The MC7750 provides signals for:•Power control of the module from the host•LED driver outputThese signals are summarized in Ta b l e 4-5 and paragraphs that follow.W_DISABLE_N — Wireless disableThe host device uses W_DISABLE_N (pin 20) to enable / disable the WWAN or radio modem. When disabled, the modem cannot transmit or receive information.Letting this signal float high allows the module to operate normally. This switch follows the behavior described in [11] PCI Express Mini Card Electromechanical Specification Revision 1.2. This pin has a 20 k pull-up resistor. See Figure 4-5 on page 33 for a recommended implementation.When integrating with your host device, keep the following in mind:•The signal is an input to the module and should be driven LOW only for its active state (controlling the power state); otherwise it should be floating or (High impedance). It should never be driven to a logic high level. The module has an internal pull-up resistor to Module Power (3.3V) in place, so if the signal is floating or (high impedance), the module will power on.•Wait for two seconds after asserting W_DISABLE_N before disconnecting power.•If the host never needs to assert this power state control to the module, leave this signal unconnected from the host interface.Figure 4-5: Recommended wireless disable connectionTable 4-5: Module control signals Name Pin Description Type11.

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. See Interference from other wireless devices on page 39.Disabling the diversity antenna•For LTE 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.

RF SpecificationsRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 39Note: 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 connectionWhen 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 (shown in Figure 5-1 on page 37).•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 sensitivitySeveral 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 40) and radiated sensitivity measurement (Radiated sensitivity measurement on page 41).Note: The MC7750 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 devicesWireless 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.

Product Technical Specification & Customer Design Guidelines40 Proprietary and Confidential - Contents subject to change 2400074The 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 interferenceAll electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module.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 suppliesDevice-generated RF interferenceThe 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 performanceIt 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).

RF SpecificationsRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 41Note 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.)Radiated sensitivity measurementA 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.Sierra Wireless’ sensitivity testing and desensitization investigationAlthough AirPrime embedded modules are designed to meet carrier requirements for receiver performance, they are still susceptible to various performance inhibitors.As part of the Engineering Services package, Sierra Wireless offers modem OTA sensitivity testing and desensitization (desense) investigation. For more information, contact your account manager or the Sales Desk (see Contact Information on page 4).Note: Sierra Wireless has the capability to measure TIS (Total Isotropic Sensitivity) and TRP (Total Radiated Power) according to CTIA's published test procedure.Sensitivity vs. frequencyFor CDMA bands, sensitivity is defined as the input power level in dBm that produces a FER (Frame Error Rate) of 0.5%. Sensitivity should be measured at all CDMA frequencies across each band.For LTE bands, sensitivity is defined as the RF level at which throughput is 95% of maximum.Supported frequenciesThe MC7750 supports:•Single-band LTE — See Ta bl e 5-1 on page 42.•Dual-band CDMA — See Ta ble 5-3 on page 42.•GPS•Radio transceiver requirements for 3GPP Release 7

Regulatory and Industry ApprovalsRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 61Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093 and IC RSS-102.OEM integrationApplication of regulatory guidelinesBecause ‘near-body’ devices (handhelds, laptops, tablets, scanners, etc.) vary widely in design features, physical configurations, and use-models, module integrators shall follow the guidelines below regarding device classification and simultaneous transmission, and seek guidance from their preferred regulatory test lab to determine how regulatory guidelines will impact the device compliance. Proactive management of the regulatory process will minimize unexpected schedule delays and costs due to unplanned testing activities.Device classificationsThe OEM integrator must determine the minimum distance required between their device and the user’s body.The FCC provides device classification definitions to assist in making the correct determination. Note that these classifications are guidelines only; strict adherence to a device classification may not satisfy the regulatory requirement as near-body device design details may vary widely.FCC definitions:Portable: (§2.1093) — A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is / are within 20 centimeters of the body of the user.Mobile: (§2.1091) (b) — A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons.Per §2.1091d(d)(4) In some cases (for example, modular or desktop transmitters), the potential conditions of use of a device may not allow easy classification of that device as either Mobile or Portable. In these cases, applicants are responsible for determining minimum distances for compliance for the intended use and installation of the device based on evaluation of either specific absorption rate (SAR), field strength, or power density, whichever is most appropriate.OEM device classification processThe primary factor in determining whether a device will be classified as a Portable product or as a Mobile product is antenna separation distance (body to radiating antenna element).

Product Technical Specification & Customer Design Guidelines62 Proprietary and Confidential - Contents subject to change 2400074The review process between the OEM module integrator and the preferred regulatory test lab is a crucial step in determining the appropriate device classification, as it is impractical for Sierra Wireless to define all possible combinations of design features, antennas, physical configurations, and use-models.1. Perform a device review with the preferred regulatory test lab to confirm device classification.2. Determine the Certification type (Standalone or C2PC from an existing Modular Grant).3. If the device classification is:·Portable: Preferred regulatory test lab to determine if a PBA or KDB is required.·Mobile: Preferred regulatory test lab to determine if a PBA is required.(Note: A PBA or KDB will likely be required for new technologies such as LTE or WiMAX.)4. If the device classification is Mobile, confirm the antenna does not violate the Gain Limits specific to the module grant as specified in Important compliance information for North American users on page 60.5. Outline and execute a test plan with the preferred regulatory test lab.Testing is likely to include some or all of Parts 15, 22, 24, 27, and either SAR (for Portable devices) or MPE (for Mobile devices).6. Follow product labeling requirements as described in Important compliance information for North American users on page 60. (Ref §2.925) 7. Include the OEM product instruction manual content on page 63 boilerplate text within the host product’s instruction manual.Simultaneous transmission evaluationThe MC7750 modem has not been evaluated or approved for simultaneous transmission as the number of possible multi-transmission scenarios for this device is large. Any simultaneous transmission condition established through module integration into a customer-specific product must be evaluated per the requirements in KDB447498D01(8) and KDB616217D01,D03 (for laptop, notebook, netbook, and tablet applications).These requirements include, but are not limited to:•Transmitters and modules certified for mobile or portable exposure conditions can be incorporated in mobile host devices without further testing or certifi-cation when:·The closest separation among all simultaneous transmitting antennas is 20 cm,or·Antenna separation distance and MPE compliance requirements for All simultaneous transmitting antennas have been specified in the application filing of at least one of the certified transmitters within the host device.

Peak gain can be affected by antenna size, location, design type, etc. — the antenna gain patterns remain fixed unless one or more of these parameters change.Radiation patterns of Ant1 and Ant2 Nominally Omni-directional radiation pattern in azimuth plane.

These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits. The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50 ohm system. With antenna designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels of emissions. Tuning may include antenna pattern changes, pahse/delay adjustment, passive component matching. Examples of the application test limits would be included in FCC Part 22 and Part 24, test case 12.2.1 for GSM (3GPP TS 51.010), and test case 4.2.2 for WCDMA (ETSI EN 301 511).b.

BRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 69B: Design ChecklistThis chapter provides a summary of the design considerations mentioned throughout this guide. This includes items relating to the power interface, RF integration, thermal considerations, cabling issues, and so on.Note: This is NOT an exhaustive list of design considerations. It is expected that you will employ good design practices and engineering principles in your integration.Table B-1: Hardware integration design considerations Suggestion Section where discussedComponent placementProtect the SIM socket so the SIM cannot be removed while the host is powered up.SIM implementation on page 32If an ESD suppressor is not used, allow space on the SIM connector for series resistors in layout. (Up to 100  may be used depending on ESD testing requirements).SIM implementation on page 32Minimize RF cable losses as these affect performance values listed in product specification documents.RF connections on page 37AntennasMatch the module / antenna coax connections to 50 — mismatched antenna impedance and cable loss negatively affect RF performance.RF connections on page 37If installing CDMA and UMTS modules in the same device, consider using separate antennas for maximum performance.Antenna and cabling on page 38PowerMake sure the power supply can handle the maximum current specified for the module type.Power consumption on page 45Limit the total impedance of VCC and GND connections to the SIM at the connector to less than 1  (including any trace impedance and lumped element components — inductors, filters, etc.). All other lines must have a trace impedance less than 2 .SIM implementation on page 32Decouple the VCC line close to the SIM socket. The longer the trace length (impedance) from socket to module, the greater the capacitance requirement to meet compliance tests.SIM implementation on page 32EMI / ESDInvestigate sources of localized interference early in the design cycle.Methods to mitigate decreased Rx performance on page 40

CRev 4 Sep.11 Proprietary and Confidential - Contents subject to change 71C: TestingNote: All AirPrime embedded modules are factory-tested to ensure they conform to published product specifications.Developers of OEM devices integrating Sierra Wireless AirPrime embedded modules should include a series of test phases in their manufacturing process to make sure that their devices work properly with the embedded modules. Suggested phases include:•Acceptance testing — Testing of modules when they are received from Sierra Wireless•Certification testing — Testing of completed devices to obtain required certifications before beginning mass production•Production testing — Testing of completed devices with the modules embedded•Quality assurance testing — Post-productionAT command entry timing requirementSome AT commands require time to process before additional commands are entered. For example, the modem will return “OK” when it receives AT!DAFTMACT. However, if AT!DASBAND is received too soon after this, the modem will return an error.When building automated test scripts, ensure that sufficient delays are embedded where necessary to avoid these errors.Acceptance testingNote: Acceptance testing is typically performed for each shipment received.When you receive a shipment from Sierra Wireless, you should make sure it is suitable before beginning production.From a random sampling of units, test that:•Units are operational•Units are loaded with the correct firmware version

Product Technical Specification & Customer Design Guidelines72 Proprietary and Confidential - Contents subject to change 2400074Acceptance test requirementsTo perform the suggested tests, you require a test system in which to temporarily install the module, and you must be able to observe the test device’s LED indicator.Acceptance test procedureThe following is a suggested acceptance testing procedure using Sierra Wireless’ Watcher™ software:Note: You can perform these tests using appro-priate AT commands.Test 1: Check power-up and initialization1. After installing the module, start the test system.2. Launch Watcher.3. Check the LED — If the LED is off, there is a problem with the module or with the connection to the LED.Test 2: Check version numbers1. From Watcher, select Help > About.2. Verify that the firmware version in the About window is correct.3. Close the About window.If the module fails either of these tests, or is not recognized by Watcher:1. Replace the module with one that is known to work correctly and repeat the tests.2. If the tests are successful, reinstall the original module and repeat the tests.If the module still does not work correctly, contact your account manager.Certification testingNote: Typically, certification testing of your device with the integrated module is required one time only.The AirPrime embedded module has been certified as described in Regulatory and Industry Approvals on page 59.When you produce a host device with a Sierra Wireless AirPrime embedded module, you must obtain certifications for the final product from appropriate regulatory bodies in the jurisdictions where it will be distributed.The following are some of the regulatory bodies from which you may require certification — it is your responsibility to make sure that you obtain all necessary certifications for your product from these or other groups:•FCC (Federal Communications Commission — www.fcc.gov)•Industry Canada (www.ic.gc.ca)•CSA (Canadian Standards Association — www.csa.ca)

Make sure that the tests you perform exercise functionality to the degree that your situation requires.Use an appropriate test station for your testing environment (see Acceptance test requirements on page 72 for suggestions) and use AT commands to control the integrated module.Note: Your test location must be protected from ESD to avoid interference with the module and antenna(s), assuming that your test computer is in a disassembled state.Also, consider using an RF shielding box — local government regulations may prohibit unauthorized transmissions.Functional production testThis section presents a suggested procedure for performing a basic manual functional test on a laboratory bench using an AirPrime embedded module and a Mini Card Dev Kit. When you have become familiar with the testing method, use it to develop your own automated production testing procedures.

Product Technical Specification & Customer Design Guidelines74 Proprietary and Confidential - Contents subject to change 2400074Suggested production testsConsider the following tests when you design your production test procedures for devices with the AirPrime module installed.•Visual check of the module’s connectors and RF assemblies•Module is operational•USB connection is functional•LED is functional•W_DISABLE_N (module power down)•Firmware revision check•Rx tests on main and auxiliary paths•Tx testProduction test procedureThe following is a suggested test plan — you must decide which tests are appropriate for your product. You may wish to add additional tests that more fully exercise the capabilities of your product.Using an appropriate Dev Kit-based test station, and referring to the appropriate AT command references:1. Visually inspect the module’s connectors and RF assemblies for obvious defects before installing it in the test station.2. Ensure that the module is turned off before beginning your tests — Drive W_DISABLE_N low.3. If using Linux, determine if any USB devices are currently connected to the computer:a. Open a shell window and enter the command ls / dev / tty / USB*.b. Record the ttyUSBn values that are returned; these are the currently connected USB devices. If the command returns “no such file or directory”, there are no devices currently connected.4. Tes t W_DISABLE_N — Turn on the module by letting W_DISABLE_N float (high impedance).5. Test USB functionality — Check for USB enumeration.·(Windows systems) The Device Manager shows Sierra Wireless items under Ports (COM & LPT). The devices shown depend on the module type. For example:]·(Linux systems) Enter the command ls / dev / tty / USB* and then record and compare the results with those from Step 3. If there are any new ttyUSBn devices, then the modem has enumerated successfully. (There should be seven new devices) For example:

Inject a carrier signal at -110dBm, frequency 1575.52 MHz into the GPS Rx path. (Note that this is 100kHz higher than the actual GPS frequency.)2. Test the signal carrier-to-noise level at the GPS receiver:a. AT!ENTERCND (Unlock extended AT command set.)b. AT!DAFTMACT (Put modem into factory test mode.)c. AT!DACGPSTESTMODE=1 (Start CGPS diagnostic task.)d. AT!DACGPSSTANDALONE=1 (Enter standalone RF mode.)e. AT!DACGPSMASKON (Enable log mask.)f. AT!DACGPSCTON (Return signal-to-noise and frequency measurements.)g. Repeat AT!DACGPSCTON five to ten times to ensure the measurements are repeatable and stable.3. Leave the RF connection to the Mini Card device intact, and turn off the signal generator.4. Take several more !DACGPSCTON readings. This will demonstrate a 'bad' signal in order to set limits for testing, if needed. This frequency offset should fall outside of the guidelines in the note below, which indicates that the CtoN result is invalid.5. (Optional) Turn the signal generator on again, and reduce the level to -120dBm. Take more !DACGPSCTON readings and use these as a reference for what a marginal / poor signal would be.Note: The response to AT!DACGPSCTON for a good connection should show CtoN within 58 +/- 5dB and Freq (frequency offset) within 100000 Hz +/- 5000 Hz .Quality assurance testingNote: QA is an ongoing process based on random samples from a finished batch of devices.The quality assurance tests that you perform on your finished products should be designed to verify the performance and quality of your devices.The following are some testing suggestions that can confirm that the antenna is interfaced properly, and that the RF module is calibrated and performs to specifications:•Module registration on cellular networks

FER can be measured for the specified receiver sensitivity of -104 dBm. The objective of this test is to determine if the FER measured is within the acceptable limits for the specified receiver sensitivity of the module. Unlike the FER tests performed during production testing, this test determines the receiver performance without the influence of the noise factor (AWGN), but with extremely low cell power. The reported FER and the confidence level must be <1% and >95% respectively for the test to be considered a pass.Suggested testing equipmentTo perform production and post-production tests, you will require appropriate testing equipment. A test computer can be used to coordinate testing between the integrated module (on the development kit or host) and the measurement equipment, usually with GPIB connections. The suggested setup includes a power meter to test RF output power and a signal generator to evaluate the receiver.Testing assistance provided by Sierra WirelessExtended AT commands have been implemented to assist with performing FTA GCF tests and portions of CE Mark tests requiring radio module access.
