Low power network module with IP-addresses

Radio Module that enables secure wireless low power IPv6 communication for sensors and small devices.

It utilizes 6loWPAN, the first IETF standard to build wireless, low power IP-based sensor and device networks.

Radio Performance:
The module operates in the 868/915MHz ISM Bands, which are less crowded compared to the 2.4GHz and 5.6GHz bands utilized by Wireless LAN,
Bluetooth and video surveillance. Further the frequency band has much better radio propagation characteristics. This allows for higher range with less
power consumption, reducing infrastructure cost and extending battery lifetime.
The radio module MAC and PHY is compliant to the IEEE 802.15.4-2003 standard, which specifies a RF data rate of 20kbit/s in the European Union and 40kbit/s in North America.

Wireless Network Processing:
The radio module is powered by an ARMâ„¢ Cortex-M3 microcontroller which allows for fast network processing with advanced security and data
integrity. The security firmware enables standard compliant end-to-end IPv6 Encryption. A tailored IPSec and IKEv2 subset was selected to encrypt and sign the outgoing and ingoing data with limited power consumption and memory usage. The radio module is ready for implementation of the up-coming IP-based Mesh Routing Standard (ROLL, Routing over Low power Lossy networks).

Command Interface Firmware

The 6LoWPAN Radio Module is controlled via a command interface to be used via SPI, UART and Virtual USB COM Port. It has fixed commands to
open sockets for reception and transmission of packets, to setup radio channels, and to configure the MAC layer. Further the IPSec key database is maintained and new keys are generated and exchanged on request. The software controls external LEDs for status indication. An interrupt pin is raised if new packets have been received or an error has occurred.

Availability
The ZWIR4511 module is already on the market.  For big volume projects you can also ask for the ZWIR4501 transceiver chip and a STM32 microcontroller. Also a development kit and a 6loWPAN to Ethernet router module is available. More details by email hn (at) gsm-modem.de.

  1. A Low power, what is it good for? Just waste of time. Everything was already set.

  2. Hi Frank, what about to ask Google, why the selected 6LoWPAN and will put an own protocol on top. Why they will make it open source? Why Google launched Android@Home?
    I visited your website and have seen that you are in medical applications. Frank, I am able to connect all your equipment to my WIFI network easy. I do not need AC power, because it could run on battery. If we your centrifugation with power on AC will get connect to my 6LoWPAN radio module, then this can run as a 6LoWPAN router easy. With the freezers we can do the same. Is your BioPhotometer a mobile device? If yes then we have to save power. The thermo mixers could start to communicate too. Last but not least any device in a medical laboratory could start to communicate. We can access to all devices, because independent on the supplier, because it is a simple IP communication.

    6LoWPAN is UDP/IP riding on radio. That means I can access with any PC, laptop, tablet or smartphone to any device easy. It is the Internet of Things on low power by using of well know communication standards like IP and if you like with security level on IPsec from end to end.
    You just plug an USB dongle to your router or connect an Ethernet to 6LoWPAN bridge to your PC and then you can access to a low power IP based network on 868 or 915 MHz.
