IMG02 LTE RF Module OEM User Manual Features LTE: LTE-FDD, Rel9, Category 4, Band 13 GPS: Standard GPS/AGPS supported Antenna Connector LTE Main/Diversity, GPS UICC Support USIM, ISIM Form Factor M.2 (NGFF) Dimensions 42x32x2.7 mm Required connectors Here is the description about the connectors used to integrate the modem into the host device. RF Bands The LTE frequency bands the modem supports LTE Uplink Downlink Band 13 777 MHz ~ 787 MHz746 MHz ~ 756 MHz U.FL #1 U.FL #2 U.FL #1 : LTE Main Port U.FL #2 : LTE Diversity Port M.2 (NGFF) Connector Shielding The module is fully shielded to protect against EMI and must not be removed. 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 ohm 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. 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 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.? 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. Notice 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 totally lost. Although significant delays or losses of data are rare when wireless devices such as the WNC modem are used in a normal manner with a well-constructed network, the WNC 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. WNC accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the WNC modem, or for failure of the WNC modem to transmit or receive such data. Safety and Hazards Do not operate the WNC 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 WNC modem MUST BE POWERED OFF. The WNC modem can transmit signals that could interfere with this equipment. Do not operate the WNC modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the WNC modem MUST BE POWERED OFF. When operating, the WNC 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 do…
