In case of disasters, a dependable communication community is important. The emergency facilities want to have the ability to alternate info to coordinate their response within the subject. Service suppliers have to maintain their community dwell. Energy utilities want to have the ability to maintain the electrical grid up and working.
In Europe, the communication networks used to regulate elements of the facility grid and all different important infrastructure, are required to stay operational for at the least 24 hours within the occasion of an influence failure. That is effectively past what most industrial 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 important industries to order the 450 MHz band of their areas to deploy non-public 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 providers.
A key differentiator of the LTE450 MHz band is its long-range protection. The excessive frequencies can ship increased information charges to any variety of good 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 industrial 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 leads to:
- A diminished variety of base stations should be saved 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 important units within the occasion of an influence failure.
As well as, the diminished 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 places.
Thus LTE 450 is a resilient mobile communication community tailor-made to the wants of mission and enterprise important use circumstances. Few examples:
- a non-public wi-fi community to attach hundreds of SCADA programs used to regulate 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 good energy grids.
Cisco resolution for important networks
Cisco has launched an LTE 450Mhz plug in module for the favored Cisco Catalyst IR1101 Rugged Router. This platform supplies the power to hook up with 450Mhz networks and moreover supplies a second fallback module for personal 4G, 5G or industrial mobile networks.
Determine 1: The Catalyst IR1101 Rugged router
Vital visitors (corresponding to SCADA or different important management visitors) could be routed through 450Mhz and non-critical visitors routed through the mobile connections.
The IR1101 rugged router additionally supplies safe encrypted tunnels for important 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 important networks.
