In case of disasters, a dependable communication community is essential. The emergency facilities want to have the ability to trade data to coordinate their response within the subject. Service suppliers must maintain their community reside. Energy utilities want to have the ability to maintain the electrical grid up and working.
In Europe, the communication networks used to manage elements of the ability grid and all different essential infrastructure, are required to stay operational for not less than 24 hours within the occasion of an influence failure. That is properly past what most industrial mobile networks can supply.
The answer recognized by the power trade is LTE 450. Public safety and catastrophe restoration (PPDR) rules in Germany, Scandinavia, and components of Africa enable essential 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 greater information charges to any variety of good units, 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 industrial LTE, an entire countrywide community would possibly require tens of 1000’s of base stations to realize full geographical protection. LTE 450 solely takes a couple of 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 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 essential 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 by partitions and different stable 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 essential use instances. Few examples:
- a personal wi-fi community to attach 1000’s of SCADA techniques used to manage 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 good energy grids.
Cisco resolution for essential networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform gives the flexibility to hook up with 450Mhz networks and moreover gives a second fallback module for personal 4G, 5G or industrial mobile networks.
Determine 1: The Catalyst IR1101 Rugged Router
Crucial visitors (reminiscent of SCADA or different essential management visitors) might be routed through 450Mhz and non-critical visitors routed through the mobile connections.
The IR1101 rugged router additionally gives safe encrypted tunnels for essential 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 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 to your essential networks.
