The modem is one of the biggest energy guzzlers in M2M and Internet of Things applications. So the power consumption rockets upwards enormously during every data transmission. However, it is precisely that energy consumption that is a relevant feature in a variety of applications. Think about the increasing number of various gadgets, wearables or Smart Home Devices such as fire alarms or defibrillators in public buildings or busines premises. For a lot of these applications there is no power supply available. However, the devices need to operate over a long time.
Separate architecture ensures low energy consumption
Due to the separation of modem and MCU, it is possible to put the modem into a sleep mode with no impact on the execution of the script. The modem is only switched on during a data transmission. Thus, the average power consumption in the interval mode can be reduced to 22μA with the rapidM2M M220. When using a D-cell in the interval mode that means a running time of up to 8 years. Other modes are available as well. During the interval mode the data is transferred in adjustable intervals. In the wakeup mode additional transmissions to the regular intervals can be initiated. This of course requires a certain willingness of the modem in order to initiate a transmission from the server platform. The energy consumption increases here to 3mA. In online mode the module constantly sends data and the modem is permanently switched on. This results in an average power consumption of 27mA.
Since the uplink module or the modem is disconnected from the MUC, it can be easily replaced. Such a data transmission is possible not only via GSM but also via LoRa, LAN or Bluetooth. However, the MCU is exchangeable. In the rapidM2M M220 a 32Bit ARM Cortex-M3 MCU is used. Based on the ARM architecture, the script is easily portable to other MCUs. The built-in flash memory is expandable. So even individual components can be precisely be adapted to the requirements of your application.
rapidM2M PoC Shields for rapid testing
In order to develop a quick first Proof of Concept (PoC) the rapidM2M PoC Shields are available with different application interfaces. You insert your rapidM2M module in the PoC Shield and start directly to develop. The PoC Shields are available in a basic version and with a LAN, CAN, Bluetooth Smart (BLE)/WiFi, RS232 or RS485 interface.
The quick development of a Proof of Concept is relevant in M2M and IoT applications. So success can already be shown at an early stage of the project. With Microtronics you turn your idea into a Proof of Concept within 3 weeks. Since no own development is necessary, you minimize risk and costs and a faster market launch is possible. Microtronics supports you in developing a successful, profitable business model around your application.
