I-Spectrum ye-6GHz, Ikamva le-5G

Ukwabiwa kweSpectrum ye-6GHz kugqityiwe

I-WRC-23 (iNgqungquthela yeHlabathi yoNxibelelwano ngeRadio ka-2023) isandul’ ukugqitywa eDubai, iququzelelwe yi-International Telecommunication Union (ITU), ijonge ukulungelelanisa ukusetyenziswa kwe-spectrum yehlabathi.

Ubunini be-spectrum ye-6GHz yayiyeyona nto iphambili eyayijongwa kwihlabathi liphela.

Ingqungquthela igqibe kwelokuba: Ukwabela ibhendi ye-6.425-7.125GHz (i-bandwidth ye-700MHz) kwiinkonzo zeselfowuni, ngokukodwa kunxibelelwano lweselfowuni lwe-5G.

Yintoni i-6GHz?

I-6GHz ibhekisa kuluhlu lwee-spectrum ukusuka kwi-5.925GHz ukuya kwi-7.125GHz, kunye ne-bandwidth ukuya kuthi ga kwi-1.2GHz. Ngaphambili, ii-spectra ze-frequency eziphakathi ukuya kwezisezantsi ezazibekelwe unxibelelwano lweselula zazisele zisetyenziswa ngokuzinikela, kwaye ukusetyenziswa kwe-spectrum ye-6GHz kuphela okwakungacacanga. Umda wokuqala ophezulu ochaziweyo we-Sub-6GHz ye-5G yayiyi-6GHz, ngaphezulu kwayo yi-mmWave. Ngokwandiswa komjikelo wobomi be-5G okulindelekileyo kunye namathuba amabi orhwebo lwe-mmWave, ukufaka ngokusesikweni i-6GHz kubalulekile kwisigaba esilandelayo sophuhliso lwe-5G.

I-3GPP sele imisele isiqingatha esiphezulu se-6GHz, ngakumbi i-6.425-7.125MHz okanye i-700MHz, kwi-Release 17, eyaziwa ngokuba yi-U6G ene-frequency band designation n104.

I-Wi-Fi nayo ibisoloko ikhuphisana nge-6GHz. Nge-Wi-Fi 6E, i-6GHz ifakiwe kumgangatho. Njengoko kubonisiwe ngezantsi, nge-6GHz, iibhendi ze-Wi-Fi ziya kwanda ukusuka kwi-600MHz kwi-2.4GHz kunye ne-5GHz ukuya kwi-1.8GHz, kwaye i-6GHz iya kuxhasa i-bandwidth ukuya kuthi ga kwi-320MHz kwinkampani enye ye-Wi-Fi.

Ngokwengxelo yeWi-Fi Alliance, iWi-Fi okwangoku inika uninzi lwamandla enethiwekhi, nto leyo eyenza i-6GHz ibe likamva leWi-Fi. Iimfuno zonxibelelwano lweselula ze6GHz azinangqondo kuba uninzi lwe-spectrum alukasetyenziswa.

Kwiminyaka yakutshanje, kubekho iimbono ezintathu malunga nobunini be-6GHz: Okokuqala, ukwabela ngokupheleleyo i-Wi-Fi. Okwesibini, ukwabela ngokupheleleyo unxibelelwano lweselula (5G). Okwesithathu, ukwabela ngokulinganayo phakathi kwezi zimbini.

Njengoko kunokubonwa kwiwebhusayithi yeWi-Fi Alliance, amazwe aseMelika aye abela i-6GHz yonke kwiWi-Fi, ngelixa iYurophu ikhetha ukwabela i-Wi-Fi inxalenye esezantsi. Ngokwemvelo, inxalenye ephezulu eseleyo iya kwi-5G.

Isigqibo se-WRC-23 sinokuthathwa njengobungqina besivumelwano esimiselweyo, esifezekisa impumelelo phakathi kwe-5G kunye ne-Wi-Fi ngokhuphiswano oluhambelanayo kunye nokuvumelana.

Nangona esi sigqibo sisenokungayichaphazeli imakethi yaseMelika, asiyithinteli i-6GHz ekubeni yibhendi yehlabathi jikelele. Ngaphezu koko, ubuninzi obuphantsi bale bhendi kwenza ukufikelela kuthungelwano lwangaphandle olufana nolwe-3.5GHz kungabi nzima kakhulu. I-5G iza kungenisa igagasi lesibini lencopho yokwakha.

Ngokwengqikelelo ye-GSMA, olu lwakhiwo lwe-5G luza kuqala ngo-2025, luphawula isiqingatha sesibini se-5G: 5G-A. Silindele ngolangazelelo izinto ezimangalisayo eziza kuziswa yi-5G-A.

I-Concept Microwave ngumvelisi ochwephesha wezixhobo ze-5G/6G RF eTshayina, kuquka isihluzi se-RF lowpass, isihluzi se-highpass, isihluzi se-bandpass, isihluzi se-notch/i-band stop, i-duplexer, i-Power divider kunye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokweemfuno zakho.
