Nach dem tagelangen Stromausfall im Berliner Bezirk Steglitz-Zehlendorf im Januar<\/a> , der durch einen Brand auf einer Kabelbr\u00fccke ausgel\u00f6st worden war, forderte die Expertenkommission des Senats eine fl\u00e4chendeckende Notstrompufferung an Mobilfunkstandorten f\u00fcr 72 Stunden<\/a> .<\/p>\n\n\n\n

Eine im Auftrag des Betreibers 450connect erstellte Studie von WIK-Consult zeigt nun jedoch, dass dieser Ansatz mit erheblichen wirtschaftlichen und technischen H\u00fcrden verbunden w\u00e4re. Demnach w\u00fcrde eine dreit\u00e4gige Batterieabsicherung der Funkzugangsnetze der drei etablierten Netzbetreiber j\u00e4hrlich mehrere Milliarden Euro kosten.<\/p>\n\n\n\n

Die Analyse verdeutlicht<\/a> , dass \u00f6ffentliche Mobilfunknetze grundlegend anders konzipiert sind als kritische Infrastrukturen (KRITIS). Sie seien weder in ihrer technischen Architektur noch wirtschaftlich f\u00fcr solche Krisenszenarien ausgelegt.<\/p>\n\n\n\n

Schon heute zeigt sich bei gro\u00dffl\u00e4chigen Stromausf\u00e4llen eine erhebliche Verwundbarkeit der bestehenden Netze. Wie die Forschenden anhand des Berliner Blackouts sowie des Stromausfalls in Spanien und Portugal im April 2025<\/a> darlegen, bricht die \u00f6ffentliche Mobilfunkversorgung ohne externe Energieversorgung rasch zusammen.<\/p>\n\n\n\n

In Berlin waren im Januar 2026 rund 100 Mobilfunkstandorte betroffen, die unmittelbar oder nach kurzer Zeit ausfielen. Erst nach 24 Stunden konnten mobile Netzersatzanlagen an etwa zwei Dritteln dieser Standorte eine stark eingeschr\u00e4nkte Grundversorgung \u00fcber 800-MHz-Frequenzen sicherstellen. <\/p>\n\n\n\n

\u00c4hnlich verhielt es sich in Spanien: Der Anteil der unerreichbaren Nutzer stieg binnen 30 Minuten sprunghaft an und erreichte zeitweise mehr als 50 Prozent. Selbst nach der R\u00fcckkehr der Stromversorgung dauerte es auf der iberischen Halbinsel bis zu anderthalb Tage, bis die Netze wieder vollst\u00e4ndig funktionierten.<\/p>\n\n\n\n
