Fumul de tigara afecteaza putin unda radio si wi-fi

Image
  Fumul de țigară conține particule și vapori care pot absorbi sau dispersa undele radio, inclusiv semnalele Wi-Fi. În teorie, o concentrație mare de fum între router și dispozitiv poate reduce puțin puterea semnalului. În practică: Într-o cameră obișnuită unde se fumează, impactul asupra Wi-Fi este aproape neglijabil. În spații cu fum foarte dens (de exemplu, încăperi puternic umplute cu fum sau medii industriale), atenuarea poate deveni măsurabilă. Pereții, mobilierul, obiectele metalice și distanța până la router afectează semnalul mult mai mult decât fumul de țigară.
