In case of disasters, a dependable communication community is crucial. The emergency facilities want to have the ability to trade info to coordinate their response within the discipline. Service suppliers have to preserve their community dwell. Energy utilities want to have the ability to preserve the electrical grid up and working.
In Europe, the communication networks used to regulate elements of the ability grid and all different crucial infrastructure, are required to stay operational for at the least 24 hours within the occasion of an influence failure. That is effectively past what most industrial mobile networks can provide.
The answer recognized by the power business is LTE 450. Public safety and catastrophe restoration (PPDR) rules in Germany, Scandinavia, and components of Africa permit crucial industries to order the 450 MHz band of their areas to deploy non-public LTE networks, changing legacy public security voice networks with know-how able to knowledge transmission.
This implies LTE 450 can provide privileged entry to the community, with out public mass market companies.
A key differentiator of the LTE450 MHz band is its long-range protection. The excessive frequencies can ship greater knowledge charges to any variety of sensible gadgets, however they’re affected by fast sign attenuation and require dense base station protection. Then again, the 450 MHz band sits on the opposite facet of the spectrum.
With industrial LTE, an entire countrywide community would possibly require tens of hundreds of base stations to realize full geographical protection. LTE 450 solely takes just a few thousand base stations to realize the identical protection and requires much less energy on the edge. This leads to:
- A diminished variety of base stations must be stored up and working; it’s simpler to handle the community.
- It’s simpler to achieve rural areas as a result of prolonged protection.
- Backup battery energy can be utilized to proceed to attach crucial gadgets within the occasion of an influence failure.
As well as, the diminished attenuation coming from the low frequency alerts of LTE 450, permits elevated penetration by way of partitions and different stable supplies, bringing apparent benefits for gadgets deployed indoors, underground and in different hard-to-reach places.
Thus LTE 450 is a resilient mobile communication community tailor-made to the wants of mission and enterprise crucial use instances. Few examples:
- a non-public wi-fi community to attach hundreds of SCADA programs used to regulate and monitor substations and different renewable power belongings;
- a public community to serve a broad vary of energy utilities, together with water, fuel, warmth distribution networks and sensible energy grids.
Cisco resolution for crucial networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform supplies the flexibility to connect with 450Mhz networks and moreover supplies a second fallback module for personal 4G, 5G or industrial mobile networks.
Determine 1: The Catalyst IR1101 Rugged Router
Important visitors (akin to SCADA or different crucial management visitors) may be routed by way of 450Mhz and non-critical visitors routed by way of the mobile connections.
The IR1101 rugged router additionally supplies safe encrypted tunnels for crucial visitors from the distant web site to a safe headend (e.g., Utility management heart).
For administration of remotely deployed IR1101 routers, the Cisco Catalyst SD-WAN platform helps safe zero contact onboarding, provisioning, and visibility to permit IR1101 routers to be deployed simply within the discipline.
As a member of the 450MHz Alliance, Cisco will attend their upcoming convention, 23 – 24 November 2023, in Paris, France. Come and meet us to speak about our capabilities to your crucial networks.
