Kungani izihlungi ze-RF ziba zibaluleke kakhulu?
Ukukhula okusheshayo kwedatha engenantambo yeselula kanye namanethiwekhi e-4G LTE kuye kwaholela ekukhuleni kwesidingo samabhendi amasha kanye nokuhlanganiswa kwenkampani yenethiwekhi ukuhlanganisa amabhendi ukuze kuhlangatshezwane nethrafikhi engenantambo. Inethiwekhi ye-3G isebenzisa cishe amabhendi amahlanu kuphela, futhi amanethiwekhi e-LTE manje asebenzisa amabhendi angaphezu kuka-40, futhi ngokufika kwe-5G, inani lamabhendi lizokhula ngokuqhubekayo.
Amadivayisi axhunyiwe athumela amasignali kumabhendi amaningi: iselula, i-Wi-Fi, i-Bluetooth, ne-GPS, kuyilapho egwema ukuphazamiseka. Singase sicabange ngokushesha ngama-smartphone, amaphiko oshaka agibele phezu kwezimoto, iziteshi zamaselula, irada nezinhlelo zokuxhumana, nezimboni, zesayensi, noma izinhlelo zokusebenza zezokwelapha ezixhunywe ku-inthanethi Yezinto (IoT). Kuleli qophelo, isihlungi siyadingeka ukuze siphume.
I-smartphone engenasihlungi isitini
Njengama-antenna, izihlungi ziba yingxenye ebaluleke kakhulu yabaxube benethiwekhi. Idivayisi ithola amafrikhwensi ahlukahlukene, futhi isihlungi sivumela ifrikhwensi oyifunayo ukuthi idlule ngenkathi icindezela ifrikhwensi engafuneki. Ngamanye amazwi, isihlungi sifana noGandalf kuJohn Ronald Ryall Tolkien ethi "The Lord of the Rings": "Ngeke udlule!" “Imishini yanamuhla ivamise ukuthi ifakwe izihlungi ezingu-30 kuya kwezingu-40 ukuze kugwenywe ukuphazamiseka. Lesi simo sizoba nzima kakhulu njengoba isizukulwane esilandelayo sama-smartphones asezingeni eliphezulu sidinga ezinye izihlungi.
Izinselele zedizayini yokuhlunga
Izihlungi ziyithuluzi elibalulekile lonjiniyela bokuklama be-RF, kodwa futhi babhekana nezinselele eziningi. Okokuqala, ukusebenza kwesihlungi kuyahlukahluka nezinga lokushisa. Izihlungi kumadivayisi ahlukahlukene namuhla zingamelana nezinga lokushisa eliyisilinganiso elingu-60 degrees Celsius (140 degrees Fahrenheit) noma ngaphezulu, kuyilapho izihlungi zasendlini zingakwazi ukumelana nezinga lokushisa eliphakathi kuka-25 degrees Celsius (77 degrees Fahrenheit) kanye namazinga okushisa aphakeme nakakhulu amaphiko kashaka noma izihlungi ezishumekwe phakathi uphahla. Ukuphakama kwezinga lokushisa kwesihlungi, kuba nzima kakhulu ukuhlunga imvamisa ethile, futhi maningi amathuba okuba isiginali "ikhukhuleke" iye ebhendini eseduze.
Ukulawula ukukhukhuleka kwezinga lokushisa kubaluleke kakhulu ngoba amabhendi amaningi asanda kunikezwa asondelene kakhulu namabhendi akhona. Ngesikhathi esifanayo, i-carrier aggregation (CA) ikhula ngokushesha, nabahlinzeki besevisi yeselula abahlanganisa iziteshi zenethiwekhi ezinhlanu ukuze bafakazele ukusebenza kwenethiwekhi, lapho ukuhlunga okunembile kuyimfuneko.
Ukuze kubhekwane nezinkinga zezinga lokushisa, imboni ye-RF ithuthukisa ubuchwepheshe bokuhlunga obungakhukhuleki kancane nobunganyakazi. Izihlungi ze-Surface Sonic (SAW) ne-Body Sound Wave (BAW) zigcina izinga eliphezulu lokuzinza lapho izinga lokushisa lishintsha, lihlangabezana nezidingo zokusebenza ezinzima zamadivayisi asafufusa.
Njengoba kushiwo ngenhla, isizukulwane esilandelayo sama-smartphones asezingeni eliphezulu naso sidinga ukuhlonyiswa ngezihlungi eziningi. Njengazo zonke ezinye izingxenye ze-rf, sincane kakhulu indawo yezihlungi. Onjiniyela kufanele bakwazi ukuhlanganisa izihlungi eziningi ezindaweni ezincane ukuze kusebenze okuphezulu.
Ama-Duplex, ama-triplexer, ama-cuadruplexer nama-hexaplexer abizwa ngokuhlanganyela njengama-multiplexer. Ama-Multiplexers ahlanganisa izihlungi eziningi kudivayisi eyodwa ukuze asize abaklami bonge isikhala, benze umklamo ube lula, uhlangabezane nezimfuneko zokusebenza, futhi ugweme ukuphazamiseka.
Emvelweni wanamuhla weselula, inani lamabhendi adingekayo kudivayisi liyamangaza, futhi ngokufika kwenkathi ye-5G, le nqubo izoba yimbi kakhulu. Nakuba ukusekela wonke amabhendi kungabangela izinkinga zokuphazamiseka, inkinga ingaxazululwa ngesihlungi. Ngaphandle kwezihlungi, inethiwekhi imane ingasebenzi.

Ngethemba ukuthi ungathola okufunayo, uma kungenjalo, sikunikeza nokwenza ngokwezifiso ngomdwebo wakho.
