GSM and GPS meets short-range radio

OBU (On Board Unit) and short-range radios An inexpensive  trailer detection on 2400 MHz radio modules is indeed already published. http://www.gsm-modem.de/M2M/m2m-faq/trailer-detection-active-rfid/ Through the use of ICs, which were developed for consumer products, the bill of materials is very low. Last week, a GSM / ISM Bridge required based on Linux. A GPS module is also […]

Bluetooth Low Energy versus ANT+

ANT+, Bluetooth, Bluetooth Low Energy, ZigBee – each technology has it market First of all I would like to mention, that I am supporting all RF technologies (Buetooth,Bluetooth Low Energy, ANT+, Gazel and ZigBee) mentioned in the text as below. Every technology has its market. 1. Qualification cost comparison ANT+, Bluetooth, Bluetooth Low Energy, ZigBee […]

M2M module: Embedded Linux, ARM9, GPRS module, USB and further Interfaces

Today I would like to show and to talk about a new Linux based application for wireless M2M. The PCB is already in use in several projects. Based on its enclosure it can be used as a final product for end users. It supports a lot of interfaces like SD card / MMC card, GPIO Pins , AD / DA converter, UARTs, USB Device, USB Host, I2C, SPI and JTAG. At GPIO you will find PMW (Pulse Wide Modulation), counters and other intelligent channels.

RF as Alternative for Remote Control Applications

Reference Design for RF Remote To ease the process, an RF remote control reference design such as the nRD24H1 is available. The device (transmitter) side of the nRD24H1 is implemented as a hardware module fitted on a six-button remote control application board. The module includes a PCB antenna, a 2.4GHz transceiver (the nRF24L01) and an […]
