subject: Ge864-gps: Taking M2m Wireless Modules To A Whole New Level [print this page] Advances in Machine to Machine (M2M) interaction have significantly transformed the way we manage our world. The commercial uses of GSM/GPRS/3G and GPS modules are continuing to create a diverse set of applications across multiple industries. Technology columnists and visionaries are painting a picture of a future where the line between "??bits and atoms"?? is blurred. Future applications will be processing-power hungry while the size of GSM/GPRS and GPS devices used is getting smaller. There is also a drive to minimize the power consumption of these modules. This article focuses on one such amazing module that smoothly covers all of these areas.
Introducing GE864-GPS, the smallest Quad band GSM/GPRS
module packed with integrated, single chip, full 48 channel A-GPS. Based on Telits battle tested GSM/GPRS core, the module weighs 6 grams with ultra-small overall dimensions of 30x30x2.8 mm (LxBxH). GE864-GPS is flat like a pan cake
with the classic BGA package making it a model contender for applications demanding extremely compact design. Elimination of connectors significantly reduces the overall cost of end solutions compared to conventional mounting.
Featuring the latest SiRFstarIV with assisted GPS ensuring uninterrupted positioning services at all times. The all new and highly sensitive A-GPS receiver comes with an optimized power management system enabling it to maintain a hot start capability with minimal power consumption. Assisted GPS uses network resources to further enhance the units ability to locate satellites in a short time when faced with poor signal conditions. With less than 2.5 m position resolution accuracy plus Satellite Based Augmentation System (WAAS, EGNOS, MSAS and GAGAN), the unit is highly suitable for highly integrated and precise positioning solutions specifically automotive, telematics and vehicle navigation.
What really puts the GE864-GPS in the spotlight is that it comes with two independent power supplies for the GSM engine and the GPS section respectively. The GPS chipset can work independently from the GSM chipset and still operates when the GSM is switched off or in power saving mode. This provides the customers with unmatched benefits of employing the GSM or GPS in a standalone mode. It also gives developers the freedom to be able to control and gather information in a proficient manner. AT commands can be issued to the module by using the GSM core or by deploying a micro controller. These exclusive characteristics, along with the previously mentioned Optimized Power Management System, are very advantageous for battery operated systems where data is uploaded based on a trigger such as tracking and security applications.
The module is equipped with ADC, DAC, GPIO, along with Python controlled SPI and I2C interfaces providing hassle free communications with external peripherals such as sensors and displays. Furthermore, GE864-GPS houses Python development environment, jamming detection capability, TCP/IP stack, and UDP, FTP, SMTP, ICMP protocols, all without any additional cost, making it extraordinarily cost effective. It is therefore potentially an "??all in one"?? solution for high volume applications. Like all Telit modules, GE864-GPS supports remote firmware updates and is compliant with ROHS EU directive.
