Functional description

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 command-

response protocol.

The Hiberband modem operates in one of several modes, each with their own distinctive power consumption

pattern:

• Hibernation Mode: the Hiberband modem will be in this mode most the time; with exception of its internal

real-time clock, all systems are shut off.

• Host Communication Mode: the Hiberband modem has activated the minimal set of functions needed to

receive instructions (e.g. to submit sensor data for transmission) from the application host processor.

• Geo-location Mode: the Hiberband modem will autonomously activate its GPS receiver to re-determine its

current location to stay synchronized with the HiberBand network of orbiting satellites.

• HiberBand Listen Mode: the Hiberband modem has activated its receiver in anticipation of a satellite

passing overhead.

• HiberBand Transmission Mode: the Hiberband modem has activated its HiberBand transmitter to send

sensor data to a satellite in range.

The highly energy-efficient operation of the Hiberband modem is supported by an advanced orbit prediction

algorithm that allows it to remain in hibernation mode until one of the HiberBand satellites becomes ’visible’ to

the LPGAN-enabled IoT device. The optimal communication window is determined by the current geographic

location of the device; to keep track of the actual location, the Hiberband modem is equipped with its own GPS

receiver. This geo-position information acquired by the Hiberband modem is also available to the IoT device

application through the host processor interface.

For the integration details of the Hiberband modem in your IoT device, please refer to the Hiber System

Integration Manual.

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.
