The GTCU is battery operated and features GSM/GPRS Cellular, Wi-Fi, 433 MHz, and GPS radio frequency (RF) technologies. The GTCU system consists of the Globe Tracker Communications Module (GTCM) and the Globe Tracker Antenna Module (GTAM). The GTCM contains the main PCB, battery, and an internal 433 MHz trace antenna located in the GTCM end cap. The GTAM contains an antenna array with cellular (GSM) and 433 MHz PCB trace antennas, as well as Wi-Fi and GPS patch antennas. The GTAM also contains a low noise amplifier (LNA) for the GPS. The GTCM and GTAM connect via four (4) SMB RF cable assemblies that protrude through sealed openings in their housings. The GTCM uses a connection plate in the housing for mounting the SMB connectors, a DB-9 connector for external interfacing, and LED indication. The GTCU is able to be powered from an internal battery pack or an external input. Units powered from the internal battery pack are typically in a stand-by power down state to conserve battery energy. In the simplest configuration for battery powered units, the GTCU will wake-up at pre-defined and customizable intervals. Upon wake-up the GTCU will power on the various sub-circuits, attempt to obtain a GPS fix, log any relevant data from its sensors or communication interfaces (typically UART or 433MHz), and transmit data via an appropriate wired or wireless interface if applicable (e.g. UART, 433MHz, Cellular, or Wi-Fi). Units powered externally operate similarly to battery powered units but may not enter into stand-by mode, and may have increased data acquisition and reporting frequency. The GTCM main circuit board has the following sub-circuits. • Main Processor (STM32F2) o SPI Flash Memory o JTAG • Wireless Interfaces o GSM/GPRS Cellular (Telit GE865-Quad) o Wi-Fi (802.11 b/g/n) (GainSpan GS1011MIE13) o 433 MHz Transceiver (Texas Instruments CC1110) o GPS Receiver (U-Blox IT530M) December 8, 2014 GTCU-002 Theory of Operation 4 of 8 • Wired Interfaces o External UART o Debug UART • Internal Sensors o Accelerometer (LIS3DH) o Temperature Sensor (TMP112AIDRLT) • Power Regulation and Control o 2 linear LDO (Low Drop Out) regulators o 3 switching regulators o Battery Input o External Input o FET switching networks 2 Main Processor The main processor is an ST Microelectronics STM32F2 series which features an ARM Cortex M3 core. The processor is driven from an internal R/C oscillator with a base frequency of 16MHz, an internal phase locked loop (PLL) multiplies the base to provide a core frequency of 120MHz. No formal operating systems is used, rather a simple scheduler is implemented. The STM32F2 supports a standard JTAG interface for programming and debug. An external SPI flash is used for data logging. 3 Wireless Interfaces The GTCU features three (…

RF EXPOSURE TEST FCC ID: 2AAZL-GTCU-002 Applied procedures / limit These devices are not exempted from compliance does not exceed the Commission’s RF exposure guidelines.Unless a device operates at substantially low power levels,with a low gain antenna(s),supporting information is generally needed to establish the various potential operating configurations and exposure conditions of a transmitter and its antenna(s) in order to determine compliance with the RF exposure guidelines. In order to demonstrate compliance with MPE requirement(see Section 2.1091),the following information is typically needed: Calculation that estimates the minimum separation distance(20 cm or more)between an antenna and persons required to satisfy power density limits defined for free space. Antenna installation and device operating instructions for installers(professional/unskilled users),and the parties responsible for ensuring compliance with the RF exposure requirement Any caution statements and/or warming labels that are necessary in order to comply with the exposure limits Any other RF exposure related issues that may affect MPE compliance.
