In case of disasters, a dependable communication community is essential. The emergency facilities want to have the ability to trade info to coordinate their response within the discipline. Service suppliers have to preserve their community dwell. Energy utilities want to have the ability to preserve the electrical grid up and working.
In Europe, the communication networks used to manage parts of the ability grid and all different essential infrastructure, are required to stay operational for a minimum of 24 hours within the occasion of an influence failure. That is effectively past what most business mobile networks can provide.
The answer recognized by the power business is LTE 450. Public safety and catastrophe restoration (PPDR) rules in Germany, Scandinavia, and elements 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 knowledge transmission.
This implies 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 knowledge charges to any variety of good gadgets, however they’re affected by speedy sign attenuation and require dense base station protection. However, the 450 MHz band sits on the opposite aspect of the spectrum.
With business LTE, an entire countrywide community may require tens of hundreds 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 ends in:
- A lowered variety of base stations have to be stored 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 essential gadgets 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 strong 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 essential use instances. Few examples:
- a personal wi-fi community to attach hundreds 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, fuel, 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 supplies the flexibility to hook up with 450Mhz networks and moreover supplies a second fallback module for personal 4G, 5G or business mobile networks.
Determine 1: The Catalyst IR1101 Rugged Router
Crucial site visitors (similar to SCADA or different essential management site visitors) will be routed through 450Mhz and non-critical site visitors routed through the mobile connections.
The IR1101 rugged router additionally supplies safe encrypted tunnels for essential site visitors from the distant web site 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 essential networks.
