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

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.
