Silicon Labs Eases Smart Meter Design with Wireless M-Bus Software
|By Business Wire
|May 19, 2014 04:05 PM EDT
Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive,
mixed-signal ICs, today introduced a comprehensive software solution
designed to simplify the development of wirelessly connected smart
meters for electricity, gas, water and heat resources based on the
proven Wireless M-Bus standard. Silicon Labs’ Wireless
M-Bus software complements the company’s industry-leading
microcontroller (MCU) and wireless IC products and development kits for
the rapidly growing smart metering and smart grid markets.
Wireless connectivity provides scalable, easy-to-deploy communications
technology for many smart metering applications. The Wireless M-Bus
specification, based on the European standard EN13757-4, specifies
seamless sub-GHz RF communication between various types of smart utility
meters, data concentrators, mobile readout devices and heat meters (heat
cost allocators). Wireless smart meter applications require long life
for battery-powered meters such as water, gas and heat meters. The
Wireless M-Bus communications protocol requires very little overhead for
the small amounts of data used by the meter enabling battery life up to
15-20 years. Proven over the past several years in numerous field tests
and deployments in many different countries, Wireless M-Bus has become a
widely accepted standard for smart metering in Europe, and interest in
the standard is also growing in other world regions.
Silicon Labs’ Wireless M-Bus software solution includes a comprehensive
sub-GHz wireless protocol stack that supports the S (868 MHz), T (868
MHz), C (868 MHz) and N (169 MHz) modes from the physical layer to the
application layer. The protocol stack includes application programming
interface (API)-based access for both application and extended data link
layers. The software also includes an optional serial command interface
to enable control of the Wireless M-Bus solution from an external host
The Wireless M-Bus software is available in binary/object code format
for Silicon Labs’ Si446x
EZRadioPRO® sub-GHz RF transceivers and the energy-friendly,
ARM-based 32-bit EFM32™
Leopard Gecko MCU. Physical layer configurations are provided for S,
T, C and N modes for evaluation using Silicon Labs’ Wireless
Development Suite (WDS). The software package includes complete API
documentation, physical layer scripts, test reports, a quick-start guide
and PC-based tools for evaluation. Source code is available through a
separate license agreement.
Transfer Center Embedded Design and Networking (STZEDN) developed
the sub-GHz protocol stack, which conforms to the current Wireless M-Bus
specification (EN13757-4), the Wireless M-Bus Application Layer
(EN13757-3) and the Application Layer of the Open Metering System (OMS)
Group. This robust, standards-based sub-GHz implementation enables smart
meter developers to create competitive products that are easy to install
and maintain. The STZEDN stack implements all required protocol elements
for the Wireless M-Bus standard and additional tools support. The stack
has proven interoperability with software modules from leading
manufacturers across different protocol layers and is optimized for
small footprint, excellent modularity and scalability. STZEDN also
offers additional engineering services (adaptation, customization and
optimization), training and customer support.
“Our new Wireless M-Bus software solution simplifies the process of
adding wireless connectivity to smart metering systems,” said Geir
Førre, senior vice president and general manager of Silicon Labs’
microcontroller and wireless products. “As a leading supplier of silicon
solutions to the world’s top utility meter manufacturers, we also offer
an array of sub-GHz
RF transceivers, EFM32
wireless MCUs, Ember®
ZigBee® SoCs and digital
isolation IC products for smart
metering and other Internet
of Things applications.”
Wireless M-Bus Development Kits
Silicon Labs provides extensive evaluation hardware providing an easy,
effective way to demonstrate the capabilities of Silicon Labs’ Wireless
M-Bus software solution. One Si4461-868-PDK kit and two EFM32LG-STK3600
starter kits are recommended for evaluation. The Si4461-868-PDK kit
includes two 4461-PCE14D868-EK RF pico cards enabling standalone RF
evaluation. The RF pico cards must be connected to an EFM32LG starter
kit for Wireless M-Bus software evaluation. Connection details are
included in the Wireless M-Bus Quick-Start Guide. 4463-PSQ20D169-EK RF
pico cards are also available for N-mode operation at 169 MHz.
Pricing and Availability
The Wireless M-Bus software solution is available now to customers at no
charge. For more information about Silicon Labs’ Wireless M-Bus

WebRTC defines no default signaling protocol, causing fragmentation between WebRTC silos. SIP and XMPP provide possibilities, but come with considerable complexity and are not designed for use in a web environment. In his session at @ThingsExpo, Matthew Hodgson, technical co-founder of the Matrix.org, discussed how Matrix is a new non-profit Open Source Project that defines both a new HTTP-based standard for VoIP & IM signaling and provides reference implementations.

The Internet of Things (IoT), in all its myriad manifestations, has great potential. Much of that potential comes from the evolving data management and analytic (DMA) technologies and processes that allow us to gain insight from all of the IoT data that can be generated and gathered. This potential may never be met as those data sets are tied to specific industry verticals and single markets, with no clear way to use IoT data and sensor analytics to fulfill the hype being given the IoT today.
