Det amerikanske telekommunikationsselskab Verizon og det japanske selskab NEC har lige afsluttet med succes<\/a><\/noindex> Feltstudier af et omfattende overv\u00e5gningssystem til bymilj\u00f8er og begivenheder via eksisterende fiberforbindelser. Ingen nye globale investeringer er n\u00f8dvendige - alle fiberkabler er allerede blevet lagt i jorden af Verizon og bruges til dataoverf\u00f8rsel i deres netv\u00e6rk. Det er projektets unikke karakter: for f\u00f8rste gang har operat\u00f8ren benyttet eksisterende kommercielle fiberforbindelser til dataindsamling.<\/p>\n

\"Almindelige<\/p>\n

Technology overv\u00e5gning<\/a><\/noindex> Seismiske data og temperaturforhold for fiberkabler er blevet brugt i omkring 10 \u00e5r, for eksempel inden for olieudvinding. I byer er det attraktivt at anvende denne teknologi til overv\u00e5gning af trafik og begivenheder p\u00e5 gaderne samt til overv\u00e5gning af den urbane infrastruktur som veje, tunneler, broer og bygninger. I Verizons og NECs tests kunne overv\u00e5gningssystemet, baseret p\u00e5 AI (konvolutionsneuralnetv\u00e6rk), bestemme trafikbelastning i bilstr\u00f8mmen, bev\u00e6gelsesretning og acceleration for individuelle k\u00f8ret\u00f8jer, deres v\u00e6gt samt h\u00e6ndelser p\u00e5 vejen (kollisioner og endda skud). Disse oplysninger vil ikke kun forbedre trafikken, men ogs\u00e5 hj\u00e6lpe 'f\u00f8rste reaktions' tjenester som politiet, ambulancen og redningstjenesten.<\/p>\n

Principperne for et s\u00e5dant overv\u00e5gningssystem bygger p\u00e5 analysen af tilbageholdt spredning af det optiske signal (ekkoet) i fiberkablet, n\u00e5r temperaturforvridninger eller vibrationer skaber fysiske interferenser i kommunikationslinjerne, som justeres af optiske sendere og modtagere. Hvis denne information indsamles af s\u00e6rlige modtagere og analyseres med AI, kan man knytte specifikke begivenheder til hver 'lyttende' sektor.<\/p>\n

Verizon udvider aktivt sit kabelnetv\u00e6rk. Hver m\u00e5ned \u00f8ger de l\u00e6ngden af infrastrukturen med cirka 1400 miles (2253 km). I tilf\u00e6lde af eftersp\u00f8rgsel p\u00e5 tjenesten til overv\u00e5gning af situationen p\u00e5 gaderne er Verizon klar til at implementere den p\u00e5 hele det amerikanske territorium, hvor de er til stede eller hvor den er efterspurgt.<\/p>\n
