Highly integrated, low-power communications modem for global delivery of sensor data.
The Hiberband modem is a highly integrated, low-power communications front-end designed for global delivery of sensor data through Hiber’s satellite-based Hiberband Low-Power Global Area Network (LPGAN). Designed as a compact, solderable SMT module, it is straightforward to integrate in IoT devices. The application host processor of the IoT device interacts with the Hiberband modem through a UART-based serial interface using a commandresponse protocol. The Hiberband modem provides two connectors for the Hiberband and GPS antennas.
For detailed technical documentation, please contact Hiber at [email protected].
The information on the internal GPS receiver of the Hiberband modem is provided for reference purposes only; this functionality has been discontinued. The application developer must provide current the geo-location by other means to the modem.
The mechanical drawing of the Hiberband modem is shown in figure 1 (all dimensions in millimeters).
The Hiberband modem has two antenna connectors: one MMCX-female for the Hiberband antenna and one U.FLfemale for the GPS antenna (only for versions with integrated GPS receiver).
The pin numbering scheme of the Hiberband modem is shown in figure 2. The module pins are implemented as so-called castellations that allow soldering onto a printed circuit board (PCB) using standard reflow manufacturing techniques.
The Hiberband modem provides one or two on-board antenna connectors (depending on the modem version), one for the Hiberband satellite communication, and one for the GPS antenna (for modem versions with integrated GPS receiver). The antenna details are described in section 1.
The pin function assignment is given in table 1.

The following temperature ranges are defined for operation of the Hiber LPGAN modem:
Normal operating temperature:
the Hiber LPGAN modem is fully functional and meets all its product specifications across the specified temperature range.
Extended operating temperature:
the Hiber LPGAN modem is fully functional but RF performance may be degraded.
The environmental operating ranges of the Hiber LPGAN modem are defined in table 3.
|T-operating||Typical operating temperature||+25||°C|
|ICC||Normal operating temperature||-30||+70||°C|
|Extended operating temperature||-40||+85||°C|
The frequency ranges of the Hiberband modem are given in table 4.
|Hiberband frequency range||Uplink||399.90||400.05||MHz|
|GPS frequency range||Downlink||1575.42||1575.42||MHz||Only GPS is supported|
A typical interface between the application host processor, generally a microcontroller, and the Hiberband modem is shown in Figure 3.
In the example design shown above, the host application processor runs at 3.0V, while the Hiberband modem has a +3.3V supply voltage. The processor interfaces with the Hiberband modem through a UART interface for serial device-to-device communication. Optionally, the debug UART may be used in the application. Furthermore, two GPIO pins (configured as outputs) are used to drive the RESET and WKUP inputs of the Hiberband modem, both of which have active HIGH levels. The signal levels of the processor-modem UART interfaces is set by applying the appropriate voltage to the VREF input of the Hiberband modem. Other than ensuring that the power supply is able to deliver the necessary current within a sufficiently fast transient response time, this covers the integration of Hiber’s LPGAN connectivity in an IoT device.
