Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L850-GL Hardware User Manual Page 9 of 54 This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and the maximum antenna gain allowed for use with this device is 5 dBi. 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L850-GL Hardware User Manual Page 10 of 54 IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product.

PCIe can achieve the maximum transmission rate of 2.5 GT/s, and must strictly follow the rules below in PCB Layout: The differential signal pair lines shall be parallel and equal in length; The differential signal pair lines shall be short if possible and be controlled within 15 inch(380 mm) for AP end; The impedance of differential signal pair lines is recommended to be 100 ohm, and can be controlled to 80～120 ohm in accordance with PCIe protocol; Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved. L850-GL Hardware User Manual Page 31 of 54 It shall avoid the discontinuous reference ground, such as segment and space; When the differential signal lines go through different layers, the via hole of grounding signal should be in close to that of signal, and generally, each pair of signals require 1-3 grounding signal via holes and the lines shall never cross the segment of plane; Try to avoid bended lines and avoid introducing common-mode noise in the system, which will influence the signal integrity and EMI of difference pair. As shown in Figure 3-12, the bending angle of all lines should be equal or greater than 135°, the spacing between difference pair lines should be larger than 20mil, and the line caused by bending should be greater than 1.5 times line width at least. When a serpentine line is used for length match with another line, the bended length of each segment shall be at least 3 times the line width (≥3W). The largest spacing between the bended part of the serpentine line and another one of the differential lines must be less than 2 times the spacing of normal differential lines (S1<2S); Figure 3-12 Requirement of PCIe Line The difference in length of two data lines in difference pair should be within 5mil, and the length match is required for all parts. When the length match is conducted for the differential lines, the designed position of correct match should be close to that of incorrect match, as shown in Figure 3-13. However, there is no specific requirements for the length match of transmit pair and receiving pair, that is, the length match is only required in the internal differential lines rather than between different difference pairs. The length match should be close to the signal pin and pass the small-angle bending design. Reproduction forbidden without Fibocom Wireless Inc. written authorization - All Rights Reserved.

L850-GL Hardware User Manual Page 36 of 54 3.5.3 USIM Hot-Plugging The L850 module supports the SIM card hot-plugging function, which determines whether the SIM card is inserted or detached by detecting the SIM_DETECT pin state of the SIM card slot. The SIM card hot-plugging function can be configured by “AT+MSMPD” command, and the description for AT command as shown in the following table: AT Command Hot-plugging Detection Function Description Default value, the SIM card hot-plugging detection function is AT+MSMPD=1 Enable enabled. The module can detect whether the SIM card is inserted or not through the SIM_DETECT pin state. The SIM card hot-plugging detect function is disabled. AT+MSMPD=0 Disable The module reads the SIM card when starting up, and the SIM_DETECT status will not be detected. After the SIM card hot-plugging detection function is enabled, the module detects that the SIM card is inserted when the SIM_DETECT pin is high, then executes the initialization program and finish the network registration after reading the SIM card information. When the SIM_DETECT pin is low, the module determines that the SIM card is detached and does not read the SIM card. Note: By default, SIM_DETECT is active-high, which can be switched to active-low by the AT command. Please refer to the AT Commands Manual for the AT command. 3.5.4 USIM Design The SIM card circuit design shall meet the EMC standards and ESD requirements with the improved capability to resist interference, to ensure that the SIM card can work stably. The following guidelines should be noted in case of design: The SIM card slot placement should near the module as close as possible, and away from the RF antenna, DC/DC power supply, clock signal lines, and other strong interference sources. The SIM card slot with a metal shielding housing can improve the anti-interference ability. The trace length between the SIM card slot and the module should not exceed 100mm, or it could reduce the signal quality.
