In case of disasters, a dependable communication community is crucial. The emergency facilities want to have the ability to trade data to coordinate their response within the subject. Service suppliers have to hold their community stay. Energy utilities want to have the ability to hold the electrical grid up and working.
In Europe, the communication networks used to regulate parts of the facility grid and all different crucial infrastructure, are required to stay operational for at the very least 24 hours within the occasion of an influence failure. That is effectively past what most business mobile networks can supply.
The answer recognized by the power business is LTE 450. Public safety and catastrophe restoration (PPDR) laws in Germany, Scandinavia, and components of Africa enable crucial industries to order the 450 MHz band of their areas to deploy personal LTE networks, changing legacy public security voice networks with know-how able to information transmission.
This implies LTE 450 can supply privileged entry to the community, with out public mass market providers.
A key differentiator of the LTE450 MHz band is its long-range protection. The excessive frequencies can ship larger information charges to any variety of sensible units, however they’re affected by fast sign attenuation and require dense base station protection. Then again, the 450 MHz band sits on the opposite aspect of the spectrum.
With business LTE, an entire countrywide community would possibly require tens of 1000’s 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 ends in:
- A lowered 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 as a result of prolonged protection.
- Backup battery energy can be utilized to proceed to attach crucial units within the occasion of an influence failure.
As well as, the lowered attenuation coming from the low frequency indicators of LTE 450, permits elevated penetration via partitions and different stable supplies, bringing apparent benefits for units deployed indoors, underground and in different hard-to-reach areas.
Thus LTE 450 is a resilient mobile communication community tailor-made to the wants of mission and enterprise crucial use circumstances. Few examples:
- a personal wi-fi community to attach 1000’s of SCADA methods used to regulate and monitor substations and different renewable power property;
- a public community to serve a broad vary of energy utilities, together with water, gasoline, warmth distribution networks and sensible energy grids.
Cisco answer for crucial networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform gives the flexibility to connect with 450Mhz networks and moreover gives a second fallback module for personal 4G, 5G or business mobile networks.
Determine 1: The Catalyst IR1101 Rugged Router
Vital site visitors (similar to SCADA or different crucial management site visitors) will be routed through 450Mhz and non-critical site visitors routed through the mobile connections.
The IR1101 rugged router additionally gives safe encrypted tunnels for crucial site visitors from the distant website 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 subject.
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 on your crucial networks.
