3D-P introduces hybrid LTE

Published by , Editor
Global Mining Review,

LTE provides distinct benefits in meeting the network requirements for autonomous applications in open pit and underground mining with its predictability and Quality of Service (QoS) capabilities. Experience at multiple sites worldwide, however, has highlighted a number of challenges around the cost of ‘filling’ in shadows with more LTE infrastructure, limited uplink bandwidth and needing a L2 fabric on top of LTE’s L3 architecture, especially when mission critical performance of your wireless network is a requirement.

Leveraging the multi-radio meshing capability of Rajant’s InstaMesh technology, 3D-P has introduced its new Hybrid LTE/InstaMesh® Osprey Intelligent Endpoint® (IEP). Designed to complement LTE technology, the Hybrid Osprey offers mission critical connectivity, extending the coverage and performance of LTE networks through the addition of client meshing.

Deployment of Hybrid Ospreys helps to guarantee performance of LTE deployment at 3 levels:

  1. By providing reliable and complete coverage - the meshing capability of the Hybrid Osprey allows mobile equipment to remain connected, even when outside LTE coverage or shadowed at the working face, through meshing with connected LTE neighbours or Rajant infrastructure.
  2. By addressing the limited uplink bandwidth – the hybrid Osprey analyses each connection on a packet by packet basis, to determine the best route for that particular traffic, consistently sending the traffic over the best available link.
  3. By creating a native Layer 2 network support - while many mining applications today still require a Layer 2 network, LTE is built upon a Layer 3 architecture. The Hybrid Osprey simplifies providing a Layer 2 solution by leveraging the integrated RPT tunnelling which is native to Rajant Instamesh.

“Our strong partnership with Rajant has allowed us to develop the Hybrid Osprey, which not only facilitates but also significantly improves the performance of LTE networks in the mining environment when facing coverage and uplink challenges. We could not be happier of how well the product has been received so far by the industry,” said Evan Hansen, Chief Technology Officer (CTO) at 3D-P.

"We get asked a lot about supporting LTE. Designed for outdoor wide-area networks, LTE can provide benefits through a centralised infrastructure, but lacks the dynamic resiliency to ever-changing environments provided by Rajant Kinetic Mesh®. The hybrid solution designed by our premier partner, 3D-P, overcomes the limitations of LTE to bring the capabilities of both cellular and mobile peer-to-peer technologies into a single product offering,” commented Paul Hellhake, Rajant's CTO and Co-Founder.

"Adding Rajant Kinetic Mesh extends and effectively expands LTE’s capabilities in highly mobile, increasingly autonomous operations. LTE cannot provide coverage throughout an entire industrial site, such as mining, transportation, shipping, and utilities, and this is the most mission-critical connectivity problem Rajant solves. Added benefits of a hybrid networking solution are increased flexibility, ease of deployment, and robust upstream speeds industrial operations need to run multiple mission-critical apps, like CCTV and real-time machine guidance."
