Precautions for use IoT The Wi-Fi & Bluetooth module exposed in the air (the core board inside the module or the whole composed of the core board and the base board) shall at least meet the service environmental conditions of general consumer electronic products, including but not limited to:
Working temperature: - 20 ~ 85 Storage temperature: - 20 ~ 85 Working humidity: 0~95 %RH Storage humidity: 0~98 %RH Tolerance - 20 / + 85 , every 2h a cycle, thermal shock, under the impact of the cycle of at least 20 don't appear dysfunction or performance degradation, no significant tin crack phenomenon. When working for a long time, the temperature rise of the circuit components should meet the requirements of their own specifications. To simulate the transportation process and home application scenarios, the module should be able to withstand a certain degree of mechanical impact and drop. Through certain protective means, Wi-Fi & Bluetooth module can have higher environmental adaptability.When designing a Wi-Fi & Bluetooth module, the performance, size and process margin required for the implementation of protection measures should be reserved. 19 / 22 IoT 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 FCC ID: 2ADQO3SB1150Z 4.To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, maximum antenna gain (including cable loss) must not exceed:
BT/WIFI: <1dBi 5. This module must not transmit simultaneously with any other antenna or transmitter 6. 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 integrator must be provided with labeling instructions of finished products. Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:
20 / 22 IoT 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 labelled withan FCC ID - Section 2.926 (see 2.2 Certification (labelling requirements) above). The OEM manual must provide clear instructions explaining to the OEM the labelling 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 notvisible when installed in the host, or (2) if the host is marketed so that end users do not havestraightforward commonly used methods for access to remove the module so that the FCC ID ofthe module is visible; then an additional permanent label referring to the enclosed module:Contains Transmitter Module FCC ID:2ADQO3SB1150Z or Contains FCC ID:
2ADQO3SB1150Z must be used. 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 module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the 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 21 / 22 the host continues to be compliant with the Part 15B unintentional radiator requirements.
