In case of disasters, a dependable communication community is vital. The emergency facilities want to have the ability to alternate data to coordinate their response within the discipline. Service suppliers must hold their community dwell. Energy utilities want to have the ability to hold the electrical grid up and operating.
In Europe, the communication networks used to manage parts of the facility grid and all different vital infrastructure, are required to stay operational for not less than 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 business is LTE 450. Public safety and catastrophe restoration (PPDR) rules in Germany, Scandinavia, and elements of Africa enable vital industries to order the 450 MHz band of their areas to deploy personal LTE networks, changing legacy public security voice networks with expertise 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 larger information charges to any variety of sensible gadgets, however they’re affected by speedy 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, a whole countrywide community would possibly require tens of hundreds of base stations to realize full geographical protection. LTE 450 solely takes a number of thousand base stations to realize the identical protection and requires much less energy on the edge. This ends in:
- A decreased variety of base stations have to be stored up and operating; 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 vital gadgets within the occasion of an influence failure.
As well as, the decreased attenuation coming from the low frequency indicators of LTE 450, permits elevated penetration via 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 vital use circumstances. Few examples:
- a personal wi-fi community to attach hundreds of SCADA techniques used to manage and monitor substations and different renewable vitality 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 vital networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform offers the power to hook up 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
Vital visitors (reminiscent of SCADA or different vital 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 offers safe encrypted tunnels for vital visitors from the distant website 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 on your vital networks.
