- Why is Hamburg upgrading its streetlight technology?
- The upgrade is necessary because the old TFR technology is being discontinued by the provider. The city needs to switch to the newer EFR technology to ensure the streetlights function correctly.
- What is the estimated cost of upgrading Hamburg's streetlight system?
- The cost of the streetlight upgrade in Hamburg is 15 million euros. This covers the replacement of the old receivers with the new EFR technology across the city's 126,000 streetlights.
- How is Hamburg identifying streetlights that still need to be upgraded?
- The city is using a clever strategy to find the remaining streetlights needing upgrades: they are intentionally left on during the day. Citizens report the continually lit lights, helping the city pinpoint and fix them.
- What is the main reason for the current streetlight project in Hamburg?
- Hamburg is upgrading its streetlight system from TFR to EFR technology. This involves replacing thousands of old receivers, and a city-wide effort is underway to identify and update all the streetlights.
- What challenges does Hamburg face in completing the streetlight upgrade?
- While most streetlights have been updated, some remain undiscovered due to unclear documentation on existing receiver locations. The city is relying on public reports and dedicated crews to complete the upgrade before the old system is shut down.
