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 commandresponse 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.

1 Hiberband modem pin-assignment

The pin numbering scheme of the Hiberband modem is shown in figure 1. 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 2.8.

The pin function assignment is given in table 1.

2 Product specifications

Stressing the Hiberband modem above one or more of the ratings listed in the Absolute Maximum Ratings section may cause permanent damage. These are stress ratings only. Operating the Hiberband modem at these or at any conditions other than those specified in the Operating Conditions sections of the specification should be avoided. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

Operating conditions ranges define those limits within which the functionality of the device is guaranteed.

Where application information is given, it is advisory only and does not form part of the specification.

Unless otherwise specified, all operating conditions are valid at an ambient operating temperature of +25 °C.

2.1 Absolute maximum ratings

The absolute maximum ratings of the Hiberband modem given in table 2 apply over the operating temperature range (for reasons of brevity the acronym HB is used for ’HiberBand’).

The Hiberband modem is not protected against overvoltages or reversed voltages. If necessary, voltage spikes exceeding the power supply voltage specification as given in the table above must be limited to values within the specified boundaries by using appropriate protection measures.

2.2 Operating temperature ranges

The following temperature ranges are defined for operation of the Hiberband modem:

• Normal operating temperature: the Hiberband modem is fully functional and meets all its product

specifications across the specified temperature range.

• Extended operating temperature: the Hiberband modem is fully functional but RF performance may be

degraded.
