Benefits of a Rajant Mesh Network
A Kinetic Mesh network consists of wireless BreadCrumb nodes that can be placed anywhere.
Each node will automatically connect to the network as soon as it’s switched on.
Any number of nodes can be used in the network, allowing the signal to extend into remote areas that usually don’t receive signal.
There are tonnes of benefits of a mesh network. Below we have listed some of the most important ones.
1. No single point of failure
A traditional WiFi network contains a linear pattern of nodes. This means if one fails, the whole network goes down.
With a Kinetic Mesh network, there are multiple connected nodes with no specific path. Each node can act independently.
With Rajant’s patented InstaMesh technology, if one connection fails it will instantly re-route itself to the next best available path, removing any possibility of downtime on your end.
2. Easily scalable for a future-proof solution
This type of network is easily expandable. Additional nodes will instantly become part of the network once they are switched on.
If you’re looking to expand your site in the future, this solution is for you.

3. Wireless nodes can be placed anywhere
Rajant BreadCrumb Nodes are extremely rugged, allowing them to be placed anywhere, even in extreme environmental conditions or in locations that usually don’t receive RF signal.
This is ideal for industries that heavily rely on connectivity, and may also work in locations that usually don’t receive signal.
Ideal applications include:
- Green
- Healthcare
- Mining/Tunneling
- Oil and Gas
- Ports
- Manufacturing

4. Provides configurable encryption options for data transfer
Kinetic Mesh enables video, voice and data applications where strong security is essential.
Rajant BreadCrumb Nodes provide configurable per-hop, per-packet data authentication and encryption options. This way, you can rest assured that your data will be kept in safe hands.
Case Study: Stanwell’s Meandu Mine
Rajant Corporation has partnered with Acubis Technologies to deliver the Peregrine and Hawk wireless BreadCrumb nodes to Stanwell’s Meandu Mine, Australia.
The challenge: Stanwell’s Meandu Mine was struggling with the ever-evolving data and application requirements of its operation network. The network supports CCTV, access control, in-vehicle management, and autonomous haulage and needed additional throughput that could be provided by the Peregrine and Hawk BreadCrumbs. The network conditions are harsh. with large, towering ridges around the mines with multiple applications running at once.

Stanwell owns Tarong power stations, one of Queensland’s largest electricity generating sites, with coal coming from the Meandu Mine. This means there is high dependency on sustained operations and critical infrastructure security.
Rajant Peregrine and Hawk nodes are robust and secure. They have the ability to grow with the capacity needs for future applications, delivering a cost-saving solution to Stanwell’s thermal power production.

Circular polarised antennas in mining industries
Circular polarisation has opened a new door in underground mining and tunnelling communication. It allows antenna signal to travel through tunnels, avoiding potential obstructions, and creating a reliable signal throughout.
The radio waves transmitted with this type of polarisation are not constrained to just linear or horizontal situations when bouncing off the walls. They create a mirror effect, making a cylinder shape as they travel down the tunnel. The radio waves can radiate around obstacles, enabling them to adapt well in various tunnel dimensions. Circular polarisation prevents these waves from fading, which they are likely to do with vertical and horizontal polarisation, and allows those working in these conditions to maintain constant communication and situational awareness.
The Poynting MinePoynt HELI antennas have been designed for use in mining and tunnelling industries, with patented circular polarisation technology.
There’s been numerous tests performed in mines over the past few years to examine the benefits of using these antennas. One of these tests involved a large train moving through a tunnel. Significant signal loss was expected, but was unchanged due to the way the signal propagated around the obstacle.
Within these tunnels there are lots of potential issues that can affect the strength of the signal, including:
- Reflective tunnel surfaces
- High clutter environments that occupy and obstruct the standard propagation paths
- Narrow spaces
- No line of site, due to twisting tunnels and irregular turns
- Irregular dimensions and shapes of tunnels
The HELI antennas have been designed to overcome these obstructions and maintain a reliable signal within these harsh environments.
TYPES OF POLARISATION

Linear Polarisation (vertical and horizontal)
- Rotates unpredictably down a tunnel
- The propagation is affected by tunnel dimensions and surfaces
- Signal is unreliable and can fade
- Unable to propagate around obstacles
- First reflections cause significant signal interference
Circular Polarisation

- Contains all polarisations, making significantly more reliable radio links
- Propagation adapts better within tunnel dimensions
- Circular polarisation propagates past obstacles and obstructions more reliably
- You can get both left-hand and right-hand circular polarisation
The MinePoynt HELI range has been established for several years, and is deployed in a number of mines and tunnels across Europe, Australia, Africa, USA, Canada and more. The range offers both dual-band 2.4/5GHz and LTE/5G antennas in a smaller size enclosure compared to their bigger brothers, the popular HELI-3, HELI-4 and HELI- 8. The antennas offer medium to high gain, whilst providing the smallest possible installation height for mounting on tunnel roofs and walls.

Benefits of RTLS in healthcare industries
Hospitals are busy, complex environments that are always changing, no two days are the same. The primary focus of hospital staff is to provide patients with straightforward access to care. They need their equipment and tools to be in the right place at the right time, so no time is wasted, and they can offer assistance as quickly as possible.
For the workflow to run efficiently, medical departments need to ensure their assets are managed securely and resources are used productively. Siemens RTLS system allows healthcare industries to do just that, with a completely transparent view of the entire facility and its assets, in real time.
The solution allows medical professionals to:
- Keep track of assets in real-time
- Improve the patient experience by increasing productivity and focus on patient care
- Increase staff satisfaction by enhancing interactions and increasing motivation of the workforce
- Improve workflows and optimise clinical operations by automating processes

The solution uses sensor-based tracking technology to identify places and locate all valuable assets, including objects, patients, and staff. Each asset is equipped with a tag, that uses wireless transmissions to send location data to receivers (repeaters) that are installed throughout the facility. The data can then be processed into actionable insights and becomes visualised through virtual interfaces.
RealTime Asset Optimisation
Provides an overview of the location and status of your tracked assets.
RealTime Hospital Navigator
This is a mobile app that provides patients, visitors, and staff with a personalised 3D map of the facility, showing important locations such as waiting areas, cafes, examination rooms and specific units.

Poynting introduces two new OMNI-directional antennas
Poynting has introduced two new OMNI-directional antenna solutions, both with the same electrical specifications, but each designed for either marine applications or rural environments. These two new solutions are based on the very popular OMNI-291 and OMNI-292 antennas, also known as the best all-round LTE-5G OMNI-directional antennas. They have similar characteristics, but the two new models provide improved reception capability on the most popular 5G/LTE cellular bands.
Both antennas achieve exceptional OMNI-directional performance, with a medium gain and wide vertical beamwidth when operating on lower frequency bands. When operating on higher frequency bands, they offer high gain and a narrower, vertical beamwidth.
The OMNI-493 is tuned to cover a large range of new frequencies, ranging from 617 MHz to 3800 MHz, ensuring it will accommodate for Band 71:617-698MHz, and makes it a perfect addition to a marine and coastal portfolio. The antenna performs well on lower bands, allowing extra reach to be added, whilst providing better and stronger throughput. It has been designed specifically to prevent water ingress, allowing it to withstand tough water conditions, as well as salt water, chemical, toxic and corrosive environments.
The OMNI-493 is extremely reliable and a good all-round option that will consistently ensure 3G,4G and 5G connectivity when out at sea or in remote areas.
The OMNI-293 is the urban version of this antenna and excels when it comes to 5G frequencies. Similar to the OMNI-493, it performs well at Band 71 (617-698 MHz), which is being introduced in more and more countries. This future-proofs both antennas and makes them useable in all parts of the world. The OMNI-293 has been designed to prevent water and dust ingress when installed outdoors. It’s also UV and weather protected and can be used in commercial, industrial, residential, and rural implementations.
The exceptional wideband performance of this antenna is an important factor for future 5G and LTE technologies as they require features, such as Carrier Aggregation, to provide the best possible reception and throughput over multiple frequency bands simultaneously.

Have you heard of the Rajant MeshMapper?
The MeshMapper is a network performance survey utility that demonstrates the level of Kinetic Mesh connection in a mesh network within specific geographic locations.
The tool produces a connectivity heat map so users can analyse, diagnose, and optimise the performance of the Kinetic Mesh network. It gives network administrators full visibility of the infrastructure and how well the placements cover the active area.
When a BreadCrumb travels through a mesh infrastructure, data is obtained from the node using a GPS device, and is combined with a Signal-to-Noise Ratio (SNR), the cost to each BreadCrumb peer, and the total cost for a live trace. The MeshMapper will then use this data to create a connectivity ‘heat map’ in a KMZ file and it will then be saved onto the BC Commander host.
The file can then be viewed in a KML viewer, such as Google Earth, and the data can be viewed for the trace path, or you can select a data placemark to look at specific information for that location.
This solution gives a visual representation of the coverage and connectivity of a specific area, giving complete visibility of any connection weaknesses in specific areas, this is beneficial for network designers and administrators. The tool automatically generates data files that can be used alongside Google Earth to show how well the network performs over a travelled route.
When the heat map is generated, it is colour coded to show the paths travelled, and to give an assessment of each path. The colours vary depending on the thresholds given to networks and applications. This can be used in roundtrip engineering to validate propagation models and to work out the Total Path Cost between the mobile device and the gateway device to the wired network.

Above is an example of two travel routes, the colours represent:
Green – Total path cost 10000 or under
Orange – Total path cost 10001 and 20000
Red – Total path cost greater than 20000
