The AirPrime EM7700 is available for use on LTE and HSPA+ networks. Note: An understanding of network technology, and experience in integrating hardware components into electronic equipment is assumed. Purpose of this guide This guide addresses issues that affect the integration of AirPrime embedded modules into host products, and includes design recommendations for the host products. The Universal Development Kit A hardware development platform is available from Sierra Wireless for evaluating and developing with the EM7700. The Universal Development Kit (UDK) (for AirPrime MC-series modules) and a separate adapter board and RF cable may be ordered to use the UDK with the EM7700. The UDK contains hardware components for evaluating and developing with the module, including: • Development board • Cables • Antennas (Band 17 is not supported by supplied antennas) • Documentation suite • Other accessories For instructions on setting up the UDK, see PCI Express Mini Card Dev Kit Quick Start Guide (Document 2130705). For over-the-air LTE testing, ensure that suitable antennas are used. (Two antennas are required for this testing; Sierra Wireless offers an LTE-capable antenna covering 700–2600 MHz BW—please order part number 6000492 (Qty 1—this contains two antennas).) Rev 2 Apr.12 Proprietary and Confidential AirPrime EM7700 Hardware Integration Guide Required connectors Table 1-1 describes the connectors used to integrate the EM7700 Module into your host device. Table 1-1: Required host-module connectors a Connector type Description • Mate with I-PEX MHF-A13 connectors • Two connector jacks FPC (70-pin) • Hirose Flexible Printed Circuit (FPC) connector FH29BJ-70S-0.2SHW(05) SIM • Industry-standard connector. Type depends on how host device exposes the SIM socket • Example: UDK board uses ITT CCM03-3518 RF cables a. Manufacturers/part numbers are for reference only and are subject to change. Choose connectors that are appropriate for your own design. Proprietary and Confidential 4112206 2 2: Power Interface Overview of operation AirPrime embedded modules are designed to use a 3.7V (nominal) power supply provided by the host. It is the host’s responsibility to provide safe and continuous power to the module at all times; the module does NOT have an independent power supply, or protection circuits to guard against electrical issues. The module’s power state is controlled by the host’s assertion/ deassertion of POWER_ON and RESET_N. The module also monitors its supply voltage and requests shutdown if the supply is insufficient. Power signals The module must be connected to a 3.7V power supply. For detailed pinout and voltage/current requirements of this module, see the AirPrime EM7700 Product Technical Specification Document & Customer Design Guidelines. Rev 2 Apr.12 Proprietary and Confidential AirPrime EM7700 Hardware Integration Guide Module power states The module has five power states, as described in Table 2-1. Module is active • Module is capable of placing/receiving calls, or establishing data connections on the wireless network • Current consumption is affected by several factors, including: • • Default state. Occurs when VCC is first applied, POWER_ON is asserted (pulled high), and WWAN_DISABLE_N is deasserted • • • • Low power (‘Airplane mode’) RF enabled • • USB interface active Normal (Default state) Details Module is powered State Host is powered Table 2-1: Module power states Radio band being used Transmit power Receive gain settings Data rate Module is active State is controlled by host interface using software commands: • +CFUN=0 ([1] AT Command Set for User Equipment (UE) (Release 6) (Doc# 3GPP TS 27.007))) Sleep Off Disconnected 10 • • Normal state of module between calls or data connections • Host keeps module powered off by deasserting POWER_ON (signal left floating or tied low) • Module draws minimal current • Host power source is disconnected from the module and all voltages associated with the module are at 0 V. Module cycles between wake (polling the network) and sleep, at network providerdetermined interval. Proprietary and Confidential 4112206 3 3: RF Integration The AirPrime EM7700 operates on the frequency bands listed below. Table 3-1: LTE frequency band support Band Frequencies Band 4 (AWS) Tx: 1710–1755 MHz Rx: 2110–2155 MHz Band 17 Tx: 704–716 MHz Rx: 734–746 MHz Table 3-2: HSPA+ frequency band supporta Band Frequencies Band 1 WCDMA 2100 Tx: 1920–1980 MHz Rx: 2110–2170 MHz Band 2 WCDMA 1900 Tx: 1850–1910 MHz Rx: 1930–1990 MHz Band 5 WCDMA 850 Tx: 824–849 MHz Rx: 869–894 MHz a. WCDMA channel spacing is 5 MHz, but this can be adjusted to optimize performance in a particular deployment scenario. Table 3-3: GPS frequency band support Band Frequencies GNSS 1565–1606 MHz (wide band GPS and GLONASS) GPS (narrow band GPS) 1575.42 MHz RF connection When attaching antennas to the module: Rev 2 Apr.12 • Use I-PEX connectors (model I-PEX MHF-A13) to attach antennas to the module’s connection points. • Match coaxial connections between the module and the antenna to 50 . • Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB. • To ensure best thermal performance, if possible use the mounting holes to attach (ground) the device to a metal chassis. Proprietary and Confidential 11 AirPrime EM7700 Hardware Integration Guide Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage. 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 three mounting holes at the top and bottom 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. Shielding The module is fully shielded to protect against EMI and must not be removed. 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: 12 • A skilled RF engineer should do the development to ensure that the RF performance is maintained. • If both UMTS and CDMA modules will be installed in the same platform, you may want to develop separate antennas for maximum performance. Proprietary and Confidential 4112206 RF Integration 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 performance. • 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. Disabling the diversity antenna • Use the AT command !RXDEN=0 to disable receive diversity or !RXDEN=1 to enable 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. Interference and sensitivity Several sources of interference can affect the RF performance of the module (RF desense). Common sources include power supply noise and devicegenerated RF. RF desense can be addressed through a combination of mitigation techniques (Methods to mitigate decreased Rx performance on page 13) and radiated sensitivity measurement (Radiated sensitivity measurement on page 14). Note: The EM7700 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. 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: Rev 2 Apr.12 • 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. Proprietary and Confidential 13 AirPrime EM7700 Hardware Integration Guide 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: • CE/ETSI EN 301 908 (WCDMA), test numbers 5.3.1 (‘Radiated Emissions (UE)’) 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.) 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 selfgenerated 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. Power supply noise Noise in the power supply can lead to noise in the RF signal. The power supply ripple limit for the module is no more than 100 mVp-p 1 Hz to 100 kHz. This limit includes voltage ripple due to transmitter burst activity. Additional decoupling capacitors can be added to the main VCC line to filter noise into the device. 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: • 14 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. Proprietary and Confidential 4112206 RF Integration • 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. 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.

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 wellconstructed 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 EM7700 modem: Rev 2 Apr.12 • 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 EM7700 modem MUST BE POWERED OFF. Otherwise, the EM7700 modem can transmit signals that could interfere with this equipment. Proprietary and Confidential 17 AirPrime EM7700 Hardware Integration Guide In an aircraft, the EM7700 modem MUST BE POWERED OFF. Otherwise, the EM7700 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 EM7700 modem may be used normally at this time.
