Materion symudol
Mae ffonau clyfar a chysylltedd symudol yn rhan hanfodol o fywyd bob dydd i filiynau o bobl ledled y DU. Er mwyn deall yn well sut mae pobl yn defnyddio gwasanaethau symudol, a'r profiad a gânt, mae Ofcom wedi dadansoddi data torfol a gasglwyd rhwng mis Ionawr a mis Mawrth 2021 o tua 280,000 o ddyfeisiau Android ledled y DU.
Yn yr adroddiad hwn, rydym yn canolbwyntio ar y gyfran o gysylltiadau ar draws technolegau rhwydwaith di-wifr (2G, 3G, 4G, 5G, wi-fi), cyfradd lwyddiant y cysylltiadau symudol, yr amseroedd ymateb ar gyfer gwahanol dechnolegau symudol a sut mae pobl yn y panel yn defnyddio gwasanaethau llais a data. Rydym hefyd yn edrych ar sut mae'r rhain yn amrywio yn ôl gweithredwr a lleoliad y rhwydwaith.
