Emhlabeni wezintambo zenethiwekhi ezingenantambo , ezimbalwa zenzelwe ukugijima kumafrekhodi ama-high signaling aphezulu ngenjongo yokusekela imigomo amazinga angaphezulu kakhulu wezingcingo zokuxhumana ezingenantambo.
Iyini Inqubo ye-GHz engu-60?
Lesi sigaba sezintambo ezingenazintambo sisebenza kwibhande lokubonisa (ibanga) elizungeze i-60 Gigahertz (GHz) . (Qaphela ukuthi ububanzi bukhulu kakhulu: lezi zinhlelo zingase zikhulume ngezikhathi eziphansi njenge-57 GHz futhi ziphakeme njenge-64 GHz.). Lezi frequencies ziphakeme kakhulu kunezo ezisetshenziselwa ezinye izintambo ezingenantambo, njenge-LTE (0.7 GHz kuya ku-2.6 GHz) noma i-Wi-Fi (2.4 GHz noma i-5 GHz). Lokhu umehluko oyinhloko kuholela kumasistimu angu-60 we-GHz anezinzuzo ezithile zobuchwepheshe uma kuqhathaniswa nezinye izivumelwano zenethiwekhi njenge-Wi-Fi kodwa futhi nokunye ukulinganiselwa.
I-Pros and Cons ye-60 GHz Protocol
Ama-protocol ase-60 GHz asebenzisa kakhulu lezi zikhathi eziphezulu ukukhulisa inani le- bandwidth yenethiwekhi kanye namanani okusebenza asebenzayo angayisekela. Lezi zinhlelo zihambelana kahle ngokusakazwa kwevidiyo ephezulu kodwa zingasetshenziselwa ukudluliselwa kwedatha eziningi jikelele. Uma kuqhathaniswa namanethiwekhi we-Wi-Fi asekela amazinga amaningi wedatha phakathi kwama-54 Mbps kanye nama-300 Mbps, ama-60 GHz ama-protocol asekela ngaphezu kwe-1000 Mbps. Ngenkathi ividiyo ephezulu-definition ingasakazwa nge-Wi-Fi, idinga ukucindezelwa kwedatha okuthinta kakhulu izinga levidiyo; akukho ukucindezela okunjalo okudingekayo ekuxhumaneni kwe-60 GHz.
Ngokubuyisela isivinini esikhulu, ama-protocol ama-60 we-Gbps ahlawulela ububanzi benethiwekhi. I-Gbps engu-60 ye-wireless protocol uxhumano lwenethiwekhi ingasebenza kuphela ezindaweni ezihamba ngamamitha angaba ngu-10 noma ngaphansi. Izimpawu zomsakazo eziphezulu kakhulu ezivame ukukwazi ukudlula izivimbelo ezingokwenyama futhi ngakho-ke uxhumano lwangaphakathi luvame ukulinganiselwa ekamelweni elilodwa. Ngakolunye uhlangothi, uhla oluncishisiwe kakhulu lwala ma-radios lisho ukuthi awanamathuba amaningi okuphazamisa amanye amanethiwekhi angama-60 we-GHz, futhi enza ukuphumula kwe-evesdropping kanye nokuvikeleka kwenethiwekhi-kubonakala kunzima kakhulu kwabangaphandle.
Ama-ejensi alawulayo alawula ukusetshenziswa kwe-60 GHz emhlabeni wonke kodwa ngokuvamile akadingi amadivayisi ukuba afakwe ilayisensi, ngokungafani namanye amaqembu wesignali. Ukuba yi- spectrum engavumelekile , i-60 GHz ibonisa inzuzo kanye nesikhathi sokuthenga emakethe kubenzi bezinto ezikwazi ukuthenga izinzuzo. Lezi ziteshi zivame ukudla amandla amaningi kunezinye izinhlobo zama-wireless transmitters, noma kunjalo.
I-WirelessHD
Iqembu lemboni lidale uhlelo lokuqala lokuqala lwe-60 GHz, i-wirelessHD, ngokukhethekile ukusekela ukushicilelwa kwevidiyo ephezulu. Inguqulo engu-1.0 yezinga eliphelile ngo-2008 lisekelwa ngamazinga we-4 Gbps , kanti inguqulo 1.1 ithuthukisiwe ukwesekwa okungaphezulu kwama-28 Gbps. I-UltraGig yigama elithile lomkhiqizo we-WirelessHD ubuchwepheshe obusezingeni eliphezulu kusukela enkampanini okuthiwa i-Silicon Image.
I-WiGig
I-standard WiGig 60 GHz engenantambo (eyaziwa nangokuthi i- IEEE 802.11ad ) iphelile ngo-2010 isekela amazinga wedatha kuze kufike ku-7 Gbps. Ngaphandle kokwesekwa kwevidiyo, abathengisi be-inthanethi basebenzise i-WiGig esikhundleni sokungena nge-wire kubakhansela bamavidiyo nabahloli bekhompyutha. Umzimba wemboni obizwa ngokuthi i-Wireless Gigabit Alliance iqondisa ukuthuthukiswa kobuchwepheshe be-WiGig.
I-WiGig ne-WirelessHD iyabonakala kakhulu njengezobuchwepheshe obuncintisanayo. Abanye bakholelwa ukuthi i-WiGig ingathatha indawo ye-Wi-Fi ubuchwepheshe ngolunye usuku, nakuba lokhu kungadinga ukuxazulula izinkinga zayo zokunciphisa ububanzi.
