CONFIDENTIAL 7 1 Product Overview 1.1 Introduction LC4R module uses GCT GDM7243Q chipset which is a wireless LTE FDD/TDD solution. The chipset inside the module owns a dual core CPU. One of CPU (ARM1) is designed to run LTE modem job; the other CPU (ARM0) is designed for router or other application. In order to get full control, GCT designs three kinds of command sets.  AT commands : 3GPP standard compatible commands to control network connection  DM commands : GCT proprietary commands for calibration and NVM configuration  UCFG commands : GCT proprietary application that manages LTE NVM (Non-Volatile Memory) block used as command based interface at GDM7243 Linux kernel environment. We will use them for different purposes. 1.2 System Structure Figure 1: Device Application for CPE From above diagram, there is an UCM (Unify Connection Manager) application running in ARM0 for connnection function. To simply dial process, using it is good suggestion, and AT commands are required. If more specific dial requirement required, DM/UCFG commands are needed.

CONFIDENTIAL 8 1.3 Network structure GDM7243M network block diagram LC4R chipset, GDM7243Q, doesn’t have WiMAX function. MII ETH is not used either due to mini PCIe form factor, so usb0 is the only interface for network communication. When NAT is enabled, notebook/PC will get IP from DHCP server on br0 interface, it will be like 192.168.0.10. br0 IP is 192.168.0.1. ltepdn0 IP can be retrieved by AT command or DM command Host Interface. LC4R uses USB 2.0 for data communication. USB interface need to be enabled and usb mode need to be configured for different condition.  Connect to test board and Windows PC Auto or RNDIS mode  Connect to Linux OS CDC-EEM or CDC-ECM mode ACM port is a virtual port on USB for AT command access only. We suggested using this interface for AT command because there is no console dump data which mixes with AT command response. Device can be found at /dev/ttyACM0.

CONFIDENTIAL 9 Modem control and monitor are done by UART which is defined in reserved pin 17 & 19 of mini PCIe interface. UART0_TXD and UART0_RXD voltage is 1.8V. Default baud rate is 921600/n/8/1. If CPE board baud rate cannot support such high bit rate, reducing baud rate is doable from UART at boot loader mode or by pre-configuration. To update UART port baudrate, go to boot loader (reboot and press enter key during booting), and follow the commands to update new value. Reboot is still required to take new baudrate working.

CONFIDENTIAL 10 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. 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 21cm 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 21 cm is maintained between the antenna and users, and 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 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. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 21 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: P27LC4RT1”. The grantee's FCC ID can be used only when all FCC compliance requirements are met. Manual Information To the End User 1.4 Federal Communication Commission Interference Statement

CONFIDENTIAL 11 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 user’s 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.
