How does Bluetooth differ from NFC Near Field Communication )?<\/div>\n
NFC and Bluetooth are both relatively short-range communication technologies available on mobile phones. NFC operates at slower speeds than Bluetooth and has a much shorter range, but consumes far less power and doesn't require pairing. Cached<\/div>\n

V n\u011bkter\u00fdch ohledech jsou si podobn\u00e9, ale maj\u00ed tak\u00e9 jedine\u010dn\u00e9 vlastnosti, kter\u00e9 je odli\u0161uj\u00ed. V tomto \u010dl\u00e1nku prozkoum\u00e1me, jak se od sebe technologie Bluetooth a NFC li\u0161\u00ed, a pod\u00edv\u00e1me se na souvisej\u00edc\u00ed t\u00e9mata, v\u010detn\u011b toho, jak rychle NFC a Bluetooth p\u0159en\u00e1\u0161ej\u00ed data, zda je NFC formou technologie Bluetooth, zda mohou technologie Bluetooth a NFC koexistovat a jak\u00fd je rozd\u00edl mezi NFC a maj\u00e1ky Bluetooth. <\/p>\n

P\u0159esto\u017ee Bluetooth i NFC jsou bezdr\u00e1tov\u00e9 komunika\u010dn\u00ed syst\u00e9my, funguj\u00ed odli\u0161n\u011b. Chytr\u00e9 telefony, tablety a osobn\u00ed po\u010d\u00edta\u010de mohou d\u00edky technologii Bluetooth komunikovat bezdr\u00e1tov\u011b na kr\u00e1tk\u00e9 vzd\u00e1lenosti.

NFC naproti tomu umo\u017e\u0148uje komunikaci mezi za\u0159\u00edzen\u00edmi na kr\u00e1tkou vzd\u00e1lenost a je podmno\u017einou technologie RFID (Radio Frequency Identification).

Pro skromn\u00e9 datov\u00e9 p\u0159enosy je NFC z hlediska rychlosti obvykle rychlej\u0161\u00ed ne\u017e Bluetooth.

Je d\u016fle\u017eit\u00e9 si uv\u011bdomit, \u017ee rychlosti obou metod se mohou m\u011bnit v z\u00e1vislosti na pou\u017eit\u00e9m hardwaru a p\u0159esn\u00e9 implementaci. NFC je samostatn\u00fd standard bezdr\u00e1tov\u00e9 komunikace, nikoli podmno\u017eina Bluetooth. NFC je z velk\u00e9 \u010d\u00e1sti zam\u011b\u0159eno na bezpe\u010dn\u00e9 bezkontaktn\u00ed transakce a sd\u00edlen\u00ed dat, na rozd\u00edl od Bluetooth, kter\u00e9 je p\u0159izp\u016fsobiv\u011bj\u0161\u00ed technologi\u00ed podporuj\u00edc\u00ed \u0161ir\u0161\u00ed \u0161k\u00e1lu aplikac\u00ed.

Navzdory skute\u010dnosti, \u017ee Bluetooth a NFC jsou dv\u011b samostatn\u00e9 technologie, mohou v n\u011bkter\u00fdch situac\u00edch koexistovat.
