AW916-GL Series Module Hardware User Guide Foreword 1 Foreword 1.1 Introduction This document describes information on electrical characteristics, RF performance, structural dimensions, application environment, and others of the AW916-GL series module. With the help of this document and other related documents, the application developer can quickly understand the hardware functions of AW916-GL series module and develop the hardware of the product. FCC Certification Requirements. According to the definition of mobile and fixed device is described in Part 2.1091(b), this device is a mobile device. And the following conditions must be met:
1. This Modular Approval is limited to OEM installation for mobile and fixed applications only. The antenna installation and operating configurations of this transmitter, including any applicable source-based time averaging duty factor, antenna gain, and cable loss must satisfy MPE categorical Exclusion Requirements of 2.1091. 2. The EUT is a mobile device; maintain at least a 20 cm separation between the EUT and the users body and must not transmit simultaneously with any other antenna or transmitter. 3. A label with the following statements must be attached to the host end product: This device contains AW916-GL FCC ID: 2A8RBAW916GL 4. This module must not transmit simultaneously with any other antenna or transmitter 5. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093 If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. For this device, OEM integrators must be provided with labeling instructions of finished products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:
A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID - Section 2.926 (see 2.2 Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labeling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the modules FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module: AW916-GL: Contains Transmitter Module FCC ID: 2A8RBAW916GL or Contains FCC ID:
2A8RBAW916GL The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID. The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The users manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes, or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. This device complies with part 15 of the FCC Rules. 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. Changes or modifications not expressly approved by the manufacturer could void the users authority to operate the equipment. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with The copyright of this document belongs to Fibocom Auto Inc. and may not be reproduced without approval. 6/33 Fibocom Auto Inc. AW916-GL Series Module Hardware User Guide Foreword the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Suppliers Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Manual Information to the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. IC Statement IRSS-GEN
"This device complies with Industry Canadas licence-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired operation of the device." or "Le prsent appareil est conforme aux CNR dIndustrie Canada applicables aux appareils radio exempts de licence.

When you are driving, do not use handheld mobile terminal, even if it has a hands-
free function. Please stop and then call!
Please turn off the mobile terminal before boarding. The wireless feature of the mobile device is not allowed on the aircraft to prevent interference with the aircraft communication system. Ignoring this note may result in flight safety issue or even violate the law. When in a hospital or health care facility, please be aware of restrictions on the use of mobile terminals. Radio frequency interference may cause medical equipment to malfunction, so it may be necessary to turn off the mobile device. The mobile terminal does not guarantee effective connection under any circumstances, for example, when the mobile terminal is defaulted or SIM is invalid. In case of the above situations in an emergency, remember to use the emergency call, and make sure your device is turned on and in an area of sufficient signal strength. Your mobile device will receive and transmit RF signals when it is turned on. RF interference occurs when it is near a TV, radio, computer, or other electronic device. Keep mobile device away from flammable gases. Turn off the mobile device when you are near to gas stations, oil depots, chemical plants or explosive workplaces. There are potential safety hazards when operating electronic equipment in any potentially explosive area.

The impedance of the RF traces is usually determined by the trace width (W), the materials dielectric constant, height from the reference ground to the signal layer (H), and the space between the RF trace and the ground (S). Microstrip and coplanar waveguide are typically used in RF layout to control characteristic impedance. The following figures are reference designs of microstrip or coplanar waveguide with different PCB structures.

AW916-GL Series Module Hardware User Guide Antenna Interface Coplanar Waveguide Design on a 4-layer PCB (Layer 3 as Reference Ground) Coplanar Waveguide Design on a 4-layer PCB (Layer 4 as Reference Ground) To ensure RF performance and reliability, the following principles should be complied with in RF layout design:
Use an impedance simulation tool to control the characteristic impedance of RF traces as 50. The GND pins adjacent to RF pins should be designed as thermal relief pads, and should be fully connected to ground. The distance between the RF pins and the RF connector should be as short as possible, and all the right-
angle traces should be changed to curved ones. There should be clearance area under the signal pin of the antenna connector or solder joint. The reference ground of RF traces should be complete. Meanwhile, adding some ground vias around RF traces and the reference ground could help to improve RF performance. The distance between the ground vias and RF traces should be no less than two times the width of RF signal traces (2*W).
