Jitter joins the Alliance

Posted Posted in Members, News

Looking closer at the new DASH7 Alliance member “JITTER”

Last month we welcomed Jitter to the DASH7 Alliance, let’s look a bit closer at this interesting company and find out what the partnership brings for both parties.

Jitter is a unique company specialized in quickly realizing high quality hardware and software solutions. They can take a concept from specification to production, allowing their customers to focus on their domain. Jitter covers the full spectrum from idea to product and has helped many startups to bring their ideas to life or developed customized data acquisition and analysis setups.

The success of Jitter highly depends on developing high quality solution with the latest technology available.

The DASH7 Alliance is composed of university researchers, innovative companies, and individuals that want to make a difference in helping people connect wireless devices using battery operated transmitters that operate for multiple years between battery replacements. Joining the DASH7 Alliance helps to build the ecosystem around usage and implementation of the open source protocol.

Jitter has already used the DASH7 open standard in multiple projects, according to Ingmar Jager, co-founder of Jitter, one of the reasons for joining the alliance is to dive deeper into the specification and contribute to the development as well. Additionally, the requirement for industrial IoT solutions is increasing rapidly and the DASH7 Alliance is a good platform to position Jitter in this niche market space.

Beside this, Ingmar expresses that the existing members of the Alliance are very interesting companies and he looks forward to interacting and explore new partnerships with mutual benefits.

On the technology side, DASH7 is a very interesting IoT protocol for developers like Jitter, DASH7 is highly flexible and completely open, making it applicable for many different product solutions.

Ingmar adds that DASH7 distinguishes itself from other protocols with a higher range compared to WIFI, Bluetooth or Zigbee, a higher bit rate compared to LoRaWAN and lower cost compared to 4G / LTE. On top of that it is extremely low power making it easier to come with a low-cost solution.

Michael André, president of the DASH7 Alliance welcomes Jitter and sees it as a real contribution to the ecosystem. A company like Jitter, who has already used the technology, can accelerate global usage and at the same time contribute to the development of the specification going forward.

To summarize, the combination of a wireless network protocol like DASH7 and a solution provider like Jitter are an ideal match to drive the growth of a sustainable ecosystem based on open source software innovation.

Crowdscan joins the Alliance

Posted Posted in Members, News

In November Crowdscan has joined the DASH7 Alliance. Crowdscan is a startup from Antwerp, Belgium and is a spin-off of the University of Antwerp and Imec. Based on six years of research at the University of Antwerp and imec, CrowdScan has developed a system to measure crowd densities without using camera images, mobile phone data or other privacy-sensitive information.

They developed a wireless crowd density system that predicts size and density of large crowds. The capacity is measured in terms of humans per m². Their measurement methodology is based on radio frequency signals using #DASH7 to derive crowd size information.

They do not make use of camera images or any type of device that needs to be connected to an individual, this makes it fully anonymous and privacy non-intrusive.

More info on Crowscan and their products can be found on their website.

LPWAN vs WirelessHART

Posted Posted in Features

LPWAN compared to WirelessHART

The concept of Industry 4.0 includes both Internet of Things (IoT) and local (short-range) networks. Adoption of wireless sensor network (WSN) technologies is driving growth for the industrial Internet of Things (IIoT). Short range systems make up for the majority of connected devices however, the long-range systems like LPWAN (Low Power Wide Area Network) is are expected to increase rapidly.

Short range systems like WirelessHART or ISA100 are often used for real-time tasks and are focused on the needs for process automation like low and deterministic latency.

Long range systems like LPWAN are used to increase datapoints by deploying a large number of connected devices and focus on scalability, long range and low cost.

LPWAN is ideal for scalability, low cost and volume

WirelessHART uses the 2.4 GHz frequency and most LPWAN technologies like LoRaWAN or DASH7 use the 868 MHz frequency in Europe (920 MHz in the US). Due to the lower frequency (and data rate), LPWAN has a much longer range.

To cope with the smaller range while still limiting the number of gateways and to improve network reliability, WirelessHART uses a multi-hop mesh network, whereas LPWAN uses a star or star-of-stars network.

A mesh network routes data over neighboring devices to reach a gateway, which significantly increases battery usage for devices in a WirelessHART network.

Mesh networks require constant synchronization between the nodes to ensure correct timing and routing and need a central network manager which adds complexity and cost to the implementation of WirelessHART. An LPWAN network on the other hand is asynchronous which is less complex but is not able to give hard real-time or throughput guarantees.

Energy consumption is higher for WirelessHART compared to LPWAN devices and to meet the industry standards related to battery lifetime, the WirelessHART transmitters need large batteries resulting in large and costly devices. The transmitter is often separated from the measurement devices, whereas IoT devices generally consist of the sensor, battery and radio transmitter in one, which reduces the cost of devices significantly.

IoT is inherently an ecosystem where no single technology alone can provide a complete solution. Interoperability between devices of different vendors and even different network protocols function within one IIoT platform.

In today’s short-range networks there are a few dominant players were a system is often built up using one brand.

To summarise WirelessHART is ideal for low latency and continuous measurements whereas LPWAN is ideal for scalability, low cost and volume. Both are part of the continuous efforts to increase automation and will increase safety and efficiency on the long term, serving different application needs.

We welcome the Eclipse Foundation

Posted Posted in News

The Eclipse Foundation joins the DASH7 Alliance

We are happy to welcome the Eclipse Foundation as a new member of the DASH7 Alliance.

Due to multiple benefits for both organizations, a mutual membership was exchanged between the DASH7 Alliance and the Eclipse Foundation. Both organizations share a focus on community-driven innovation and values such as openness and vendor-neutrality. This mutual membership is only the first step in an ongoing strategic collaboration between our organizations.

As the leading open source community within the IoT industry, the Eclipse IoT Working Group plays a vital role within the IoT ecosystem and therefore is of interest to other members of the Dash7 Alliance as well. Whether it is hardware related like sensor and gateway manufacturers or IoT platform development, one of the expected benefits of this mutual membership is joint participation in industry collaborations to develop common open IoT platforms for Industrial IoT, Industry 4.0, Edge Computing, and more.

Additionally, the DASH7 Alliance recognizes the added value in moving open source reference implementations of the specification and conformance test suites as projects under the Eclipse IoT umbrella.

In short, the combination of a wireless network protocol like DASH7 and the well-governed Eclipse IoT open source projects are an ideal match to drive the growth of a sustainable ecosystem based on open source software innovation.
