In case of disasters, a dependable communication community is important. The emergency facilities want to have the ability to alternate info to coordinate their response within the discipline. Service suppliers have to hold their community dwell. Energy utilities want to have the ability to hold the electrical grid up and working.
In Europe, the communication networks used to manage elements of the facility grid and all different important infrastructure, are required to stay operational for at the least 24 hours within the occasion of an influence failure. That is nicely past what most business mobile networks can provide.
The answer recognized by the vitality trade is LTE 450. Public safety and catastrophe restoration (PPDR) rules in Germany, Scandinavia, and components of Africa enable important 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 information 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 increased information charges to any variety of sensible units, however they’re affected by fast sign attenuation and require dense base station protection. However, the 450 MHz band sits on the opposite facet of the spectrum.
With business LTE, a whole countrywide community may require tens of hundreds of base stations to attain full geographical protection. LTE 450 solely takes just a few thousand base stations to attain the identical protection and requires much less energy on the edge. This leads to:
- A decreased variety of base stations should be saved up and working; it’s simpler to handle the community.
- It’s simpler to succeed in rural areas because of the prolonged protection.
- Backup battery energy can be utilized to proceed to attach important units within the occasion of an influence failure.
As well as, the decreased attenuation coming from the low frequency alerts of LTE 450, permits elevated penetration by way of partitions and different strong supplies, bringing apparent benefits for units 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 important use circumstances. Few examples:
- a non-public wi-fi community to attach hundreds of SCADA techniques used to manage and monitor substations and different renewable vitality belongings;
- a public community to serve a broad vary of energy utilities, together with water, fuel, warmth distribution networks and sensible energy grids.
Cisco answer for important networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform offers the power to connect with 450Mhz networks and moreover offers a second fallback module for personal 4G, 5G or business mobile networks.
Determine 1: The Catalyst IR1101 Rugged Router
Important site visitors (corresponding to SCADA or different important management site visitors) will be routed through 450Mhz and non-critical site visitors routed through the mobile connections.
The IR1101 rugged router additionally offers safe encrypted tunnels for important site visitors from the distant web site to a safe headend (e.g., Utility management middle).
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 important networks.
