GSM and GPS meets short-range radio
The last two weeks has been requested the interaction between OBU (On Board Unit) and short-range radios in several times. A trailer detection on inexpensive 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 / [...]
Wireless M-Bus on 169 MHz – ME50-169
The ME50-169 Wireless M-Bus radio module featuring 25 mW output power
This license free radio module was specifically designed for meter reading in the 169 MHz band.
The M-Bus (Meter-Bus) is a European standard for remote reading of meters for electricity, gas and water. It started as a wired bus and was later on converted to wireless [...]
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.

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.
Webinar: Best in class solution for ultra-low power coin cell battery apps – Regular price: free
ANT, The nRF24AP2 family represents the best in class solution for ultra-low power coin cell battery applications. Already widely embedded into markets such as sports and healthcare ANT now has been upgraded to a 2nd generation of devices offering even better power consumption and additional features including enhanced pairing, 128-bit encryption and application profiles.

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 [...]
433MHz Wireless Transceiver Modules as an alternative with advantages
The Multi-Path-Fading problems of gigahertz applications can be avoid by using a lower ISM frequency band. The 433MHz TinyOne Lite module is a multi-channel radio board, delivering up to 10 mW in the 433 MHz ISM band (unlicensed frequency band).
