With the launch of the new HiLoNC, SAGEM has added an ultra-compact quadband GSM/GPRS module to its popular HiLo series, for use in industrial machine-to-machine (M2M) communication applications and automotive systems.

The key idea behind designing the module was to enable the connectivity of as many applications as possible with GSM/GPRS networks. Whether the system makes do with an 8-bit controller or requires a powerful CPU and operating system remains at the discretion of the system designer. As with all modules of the HiLo series, optimizing power consumption, reliability, operating temperature and, last but not least, the cost of GPRS functionality was also a primary consideration. Thanks to years of experience in the mobile wireless market, including the numerous GSM/GPRS modules already operating successfully in the field, SAGEM has once again managed to bundle many features into this new module, and at a surprisingly reasonable price.

Measuring a mere 24mm x 24mm x 2.6mm, the solderable version of the HiLoNC is well suited for systems with severely limited board space. In fact, this is why SAGEM decided against a BGA package, choosing to offer SMD technology instead, with all contacts arranged on the side of the module.
The HiLo plug-in variant measures 27mm x 27mm x 3.6mm and is equipped with a 40-pin board-to-board connector, as well as a U.FL antenna connector. In addition to U.FL connectivity, the device offers 2 pads that support optional connection of the antenna using spring-type contacts, which serves as a space- and cost-saving alternative.

A key feature of the HiLo module is its very low power consumption of less than 1.5mA in the “registered” mode, during which the module can receive incoming calls. In addition, it makes do with 3.2V to a maximum of 4.5V for the operating voltage. This is especially important for mobile devices which are powered by a Li-ion or Li-Po cell, since there is no need to add a lossy step-up conversion stage.

The standard GSM temperature range of -10°C to +55°C is frequently a big problem for industrial and outdoor applications in particular. HiLo modules, however, are designed for an operating temperature range of -40°C to +85°C. In addition, an automotive version of the HiLoNC meeting the required standards and certifications for the rough automotive environment will shortly become available.
Choosing a SAGEM module provides the added assurance that the solution comes from a globally established, European manufacturer. All modules are manufactured to highest quality standards in the company’s own production facilities in France and are based on cutting-edge technology that has been tried and tested worldwide.

About M2M Modules
M2M (machine-to-machine) modules enable machines or mobile devices to communicate with each other via wireless networks, without any human intervention, thereby transforming them into intelligent machines. Today, M2M modules are used in cash registers, credit card terminals, vending machines and alarm systems, to name just a few applications. In addition, the technology supports the maintenance and administration of remote mobile units, such as containers, vehicles and construction equipment.
