2. Overview
The new HE920 product family introduces the new 3.5G Land Grid Array (LGA) module in the
market incorporating a 2G/3G solution in a rugged automotive grade packaging.
The HE920 is a 3.5G wireless data module offering HSPA connectivity with download speeds
up to 14.4 Mbps, upload speeds up to 5.76 Mbps and manufactured under ISO TS16949.
Designed for use in the most demanding of automotive applications, the HE920 also offers
ruggedized LGA packaging with an increased robustness and cost reducing mating solution.
Two HE920 regional versions, covering different series of HSPA bands, are available whether
your market is Europe, North America, South America, Asia or Australia.
The HE920 is also fully backwards compatible to existing EDGE and GSM/GPRS networks
through integrated quad-band radios.
Additional features such as, integrated TCP/IP and UDP stack, one DAC and a two ADC
channels provide extended functionality, adding value to the end application without adding
cost.
Moreover HE920 is also available with embedded GPS/GLONASS receiver and Antenna
Diversity. The extensive interface set, which includes analog and digital audio, UARTs, USB,
PCM and user definable GPIOs, provides ease of integration of peripherals and actuators. The
HE920 is also compliant with eCall EU Directive.
The eCall project is sponsored by the European Commission and it's based on the EU directive
E112. It is intended to adopt a blackbox device installed inside vehicles, wirelessly connected to
Emergengy Centers. In case of an emergency such as an accident or by user intervention, the
black box and its sensors will send information about the event to such centers, with the chance
to establish a voice call for safety measures.
As a part of Telit’s corporate policy of environmental protection, all Telit products comply with
the RoHS (Restriction of Hazardous Substances) directive of the European Union (EU
Directive 2002/95/EG)
NOTE:
Some of the performances of the Telit modules depend on S/W version installed on the
module itself. The Telit modules S/W group is continuously working in order to add new
features and improve the overall performances. The Telit modules are easily upgraded by the
developer using the Telit Flash Programmer.
