Normal Internal Use Confidential Restricted Confidential 3 / 36 Product User Manual Important Notice to OEM integrators 1. This module is limited to OEM installation ONLY. 2. This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b). 3. The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations 4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module's intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint with the transmitter(s) rule(s). End Product Labeling When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re-

moved. If not, a second label must be placed on the outside of the final device that contains the following text: Contains FCC ID: NKRIMA2 Contains IC: 4441A-IMA2 The grantee's FCC ID/IC ID can be used only when all FCC/IC compliance requirements are met. Antenna Installation

(1) The antenna must be installed such that 20 cm is maintained between the antenna and users,

(2) The transmitter module may not be co-located with any other transmitter or antenna.

(3) To comply with FCC/IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile exposure condition must not exceed:

Standalone Condition:

10.0 dBi in PCS band 7.0 dBi in AWS band 7.5 dBi in 700 MHz Band Assuming collocated with an ordinary WLAN transmitter with 5 dBi antenna gain 7.0 dBi in PCS band 6.5 dBi in AWS band 4.0 dBi in 700 MHz Band In the event that these conditions cannot be met (for example certain laptop configurations or co-

Normal Internal Use Confidential Restricted Confidential 4 / 36 Product User Manual location with another transmitter), then the FCC/IC authorization is no longer considered valid and the FCC ID/IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC/IC authorization. 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.

IMA2 module pin definitions 1: Leave pin 142 floating; the module can turn on automatically when a power supply exists. 2: Pin 144 can be used as a wake-up as the module enters deep-sleep status. The default configuration is active high to wake up the LGA module. 3: The VREF voltage will turn off when entering the deep sleep state. Normal Internal Use Confidential Restricted Confidential 15 / 36 Product User Manual 3.

Set this pin as floating or use 0 as a reserve. 3.3.2 Wake-Up Interface(TBD) 3.3.3 Reset Signal The Reset Signal is a hardware reset signal to control the system reset directly. You can connect it to a key or a control signal. Reserve a 100k resistor to pull up to VREF and maintain a sufficient physical distance between the reset signal trace and noise and radiating signals on the PCB. 3.4 UART Interface There are two UART interfaces: a 4-bit for high-speed data transfer, and the UARTs. Definitions of the IMA2 are listed below. 1. UART0 for PPP and AT 2. UART2 for firmware download, recovery mode, and firmware debug view Figure 3-1. UART connection (example) Normal Internal Use Confidential Restricted Confidential 17 / 36 Product User Manual 3.5 UIM Interface IMA2 modules provide a UIM_DETECT input pin for UIM connectors to detect a UIM card. When a UIM card is present, UIM_DETECT should be high (1.8 V). If a UIM card is absent, UIM_DETECT should be low. Pulling UIM_DETECT to VREF with a 100k resistor is necessary. We recommend placing a 0.1 F and a 33 pF capacitor between UIM_VCC and the Ground in parallel. We also recommend placing a 33 pF capacitor between UIM_RESET, UIM_CLK, and UIM_DATA and the Ground in parallel. Refer to Figure 5 for details. We also recommend placing an electrostatic discharge (ESD) protection circuit near the UIM socket as close as possible. The Ground pin of the ESD protection component must be well-connected to the Ground plane. The following figure shows an example of a UIM card circuit. The default configuration is active High.

This type of design enables high soldering reliability during the SMT process. We recommend not placing via or micro-via that is not covered by solder resistance within 0.3 mm around the pads unless it carries the same signal of the pad itself. Refer to the following figure. Only blind holes are allowed in the pad. Through holes are not allowed.

Use of this product may be dangerous and must be avoided in the following areas:

Where it may interfere with other electronic devices in environments such as hospitals, airports, and aircraft Where there is a risk of explosion such as gasoline stations and oil refineries The user is responsible for compliance with the legal and environmental regulations of their location of use. Do not disassemble the product; any evidence of tampering will compromise the warrantys validity. We recommend following the instructions of the hardware user guides for a correct wiring of the product. The product must be supplied with a stabilized voltage source, and the wiring must conform to relevant security and fire-prevention regulations. This product must be handled with care; avoid any contact with the pins because electrostatic discharge may damage the product. Exercise the same level of caution regarding the UIM card; carefully check the instructions for its use. Do not insert or remove the UIM when the product is in power-saving mode. The system integrator is responsible for the functioning of the final product;

therefore, care must be taken for the external components of the module as well as for project or installation issuesthere may be a risk of disturbing the GSM network or external devices or of impacting device security. If you have any questions, refer to the technical documentation and the relevant regulations in force. Every module must be equipped with a proper antenna with specific characteristics. The antenna must be installed with care in order to avoid any interference with other electronic devices.
