In case of disasters, a dependable communication community is crucial. The emergency facilities want to have the ability to change data to coordinate their response within the area. Service suppliers must maintain their community dwell. Power utilities want to have the ability to maintain the electrical grid up and operating.
In Europe, the communication networks used to regulate parts of the facility grid and all different crucial infrastructure, are required to stay operational for no less than 24 hours within the occasion of an influence failure. This is nicely past what most business mobile networks can provide.
The resolution recognized by the vitality trade is LTE 450. Public safety and catastrophe restoration (PPDR) laws in Germany, Scandinavia, and elements of Africa permit crucial 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 means LTE 450 can provide 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 gadgets, however they’re affected by fast sign attenuation and require dense base station protection. On the opposite hand, the 450 MHz band sits on the opposite facet of the spectrum.
With business LTE, a whole countrywide community may require tens of 1000’s 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 lowered variety of base stations should be stored up and operating; 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 crucial gadgets within the occasion of an influence failure.
In addition, the lowered attenuation coming from the low frequency alerts 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 crucial use circumstances. Few examples:
- a personal wi-fi community to attach 1000’s of SCADA techniques used to regulate 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 resolution for crucial networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform offers the flexibility to connect with 450Mhz networks and moreover offers a second fallback module for personal 4G, 5G or business mobile networks.
Figure 1: The Catalyst IR1101 Rugged Router
Critical visitors (corresponding to SCADA or different crucial management visitors) might be routed through 450Mhz and non-critical visitors routed through the mobile connections.
The IR1101 rugged router additionally offers safe encrypted tunnels for crucial 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 area.
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.
