2. The LE910
2.1. Product Overview
The new Telit LE910 represents the next generation of Telit wireless connectivity with
xE910 form factor.
The LE910 combines the two cutting edge technologies HSPA+ and LTE. As a matter of fact,
LE910 is a 3.5G wireless data module offering HSPA+ connectivity with download speeds up
to 42 Mbps, and a 4G M2M module at the same time, providing an ultra high-speed downlink
at 100 Mbps.
The LE910 will be the first and smallest module in the market incorporating 2G/3G/4G
solution.
Designed for use in the most demanding industrial and consumer applications, the LE910
offers LGA packaging with cost effective mating solution. Three LE910 regional versions are
available, one for European, APAC and Latin American markets and two for the North
American market ( AT&T and Verizon configuration). All of them come with a multiband
configuration, covering different sets of 3G and 4G bands. Developers can take advantage of
Telit's xE910 Unified Form Factor that enables a “design once, use anywhere” strategy.
Due to its low profile, low consumption and advanced connectivity features, LE910 is
particularly suitable for applications such as mobile computing devices, PDAs, smatphones,
table PCS and counsumer or industial electronics in general.
Design your application once and choose the technology that best fits the regional
requirements for a truly seamless deployment. The LE910 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, DAC and ADC channels provide
extended functionality, adding value to the final application with no additional costs.
Moreover LE910 is also available with embedded GPS/GLONASS receiver and Antenna
Diversity. The extensive interface set, which includes USB, SPI, I2C and user definable
GPIOs, provides ease of integration of peripherals and actuators.
As a part of Telit’s corporate policy of environmenta protection, LE910 as all Telit products
comply with the RoHS (Restriction of Hazardous Substance) directive of the European Union
(Eu Directive 2011/65/EU).

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.
NOTE:
In order to meet the competitive OEM and vertical market stringent requirements, Telit
supports its customers with a dedicated Support Policy with:
Telit Evaluation Kit EVK2 to help you to develop your application;
A website with all updated information available;
An high level specialist technical support to assist you in your development;
2.2. Target Market
The LE910 is designed and developed for applications requiring high throughput, devices
requiring worldwide coverage and for applications in areas such as telematics for in-vehicle
infotainment, video security and surveillance, outdoor signs and displays, business terminals
and consumer products such as routers, mobile hot-spots, etc.

4. Evaluation Kit
In order to assist the customer in the development of the application, Telit offers the EVK2
Evaluation Kit that can be ordered separately. The EVK2 has a SIM card holder, the RS 232
serial port level translator, a direct UART connection, audio and antenna connector.
The EVK2 provides a fully functional solution for a complete data or phone application. The
standard serial RS232 9 pin connector placed on the Evaluation Kit allows the connection of
the EVK2 system with a PC or other DTE.
The development of the applications utilizing the Telit LE910 family must present a proper
design of all the interfaces towards and from the module (e.g. power supply, audio paths,
level translators), otherwise a decrease in the performances will be introduced or, in the worst
case, a wrong design can even lead to an operating failure of the module.
In order to assist the hardware designer in his project phase, the EVK2 board presents a
family of different solutions, which will cover the most common design requirements on the
market, and which can be easily integrated in the OEM design as building blocks or can be
taken as starting points to develop a specific one.
For a detailed description of the Telit Evaluation Kit, please refer to the documentation
provided with the respective Hardware User Guide and EVK2 User Manual.

5. AT Commands
The Telit LE910 module can be driven via the serial and USB interface using the standard AT
commands.
The module is compliant with:
1. Hayes standard AT command set, in order to maintain the compatibility with
existing SW programs.
2. 3GPP 27.007 specific AT command and GPRS specific commands.
3. 3GPP 27.005 specific AT commands for SMS (Short Message Service) and CBS
(Cell Broadcast Service)
Moreover the LE910 module supports also Telit proprietary AT commands for special
purposes.
For a more information about AT commands supported by the LE910 module please refer to
the document AT Commands Reference Guide.

6. Safety Recommendations
READ CAREFULLY
Be sure the use of this product is allowed in the country and in the environment required. The
use of this product may be dangerous and has to be avoided in the following areas:
Where it can interfere with other electronic devices in environments such as hospitals,
airports, aircrafts, etc.
Where there is risk of explosion such as gasoline stations, oil refineries, etc. It is
responsibility of the user to enforce the country regulation and the specific
environment regulation.
Do not disassemble the product; any mark of tampering will compromise the warranty
validity. We recommend following the instructions of the hardware user guides for a correct
wiring of the product. The product has to be supplied with a stabilized voltage source and the
wiring has to be conforming to the security and fire prevention regulations. The product has to
be handled with care, avoiding any contact with the pins because electrostatic discharges may
damage the product itself. Same cautions have to be taken for the SIM, checking carefully the
instruction for its use. Do not insert or remove the SIM when the product is in power saving
mode.
The system integrator is responsible of the functioning of the final product; therefore, care has
to be taken to the external components of the module, as well as of any project or installation
issue, because the risk of disturbing the WCDMA/GSM network or external devices or
having impact on the security. Should there be any doubt, please refer to the technical
documentation and the regulations in force. Every module has to be equipped with a proper
antenna with specific characteristics. The antenna has
to be installed with care in order to avoid any interference with other electronic devices and
has to guarantee a minimum distance from the body (20 cm). In case of this requirement
cannot be satisfied, the system integrator has to assess the final product against the SAR
regulation.
The European Community provides some Directives for the electronic equipments
introduced on the market. All the relevant information’s are available on the European
Community website:
