CONFIDENTIAL 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.
CONFIDENTIAL 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.
CONFIDENTIAL 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.
CONFIDENTIAL 1.4 Federal Communication Commission Interference Statement 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.
CONFIDENTIAL 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.
