I-6GHz Spectrum, ikamva le-5G

Ukwabiwa kwe-6GHz Spectrum Kugqityiwe

I-WRC-23 (i-World Radiocommunication Conference 2023) igqitywe kutshanje e-Dubai, iququzelelwe yi-International Telecommunication Union (ITU), ejonge ukulungelelanisa ukusetyenziswa kwe-spectrum yehlabathi.

Ubunini be-6GHz spectrum yayiyeyona nto iphambili yokuqwalaselwa kwehlabathi.

Inkomfa yagqiba: Ukwabela ibhendi ye-6.425-7.125GHz (i-700MHz bandwidth) kwiinkonzo zeselula, ngokukodwa kwi-5G yonxibelelwano lweselula.

Yintoni i-6GHz?

I-6GHz ibhekisela kuluhlu lwe-spectrum ukusuka kwi-5.925GHz ukuya kwi-7.125GHz, kunye ne-bandwidth ukuya kwi-1.2GHz. Ngaphambili, umboniso owabiweyo ophakathi ukuya-ophantsi wonxibelelwano oluphathwayo sele uzinikele ekusetyenzisweni, kunye nokusetyenziswa kwe-6GHz spectrum eseleyo ingacacanga. Umda ochaziweyo wokuqala ophezulu we-Sub-6GHz ye-5G yayiyi-6GHz, ngasentla apho kukho i-mmWave. Ngokwandiswa kwe-5G yokuphila okulindelweyo kunye nethemba elibi lentengiso ye-mmWave, ukudibanisa ngokusesikweni i-6GHz kubalulekile kwisigaba esilandelayo sophuhliso lwe-5G.

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

I-Wi-Fi nayo ibilwela i-6GHz. Nge-Wi-Fi 6E, i-6GHz ibandakanyiwe 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 ukuya kuthi ga kwi-320MHz bandwidth kumthuthi omnye kwi-Wi-Fi.

Ngokutsho kwengxelo ye-Wi-Fi Alliance, i-Wi-Fi okwangoku ibonelela ngomthamo wenethiwekhi, yenza i-6GHz ikamva le-Wi-Fi. Iimfuno zonxibelelwano oluphathwayo lwe-6GHz azinangqiqweni kuba izinto ezininzi zihlala zingasetyenziswa.

Kwiminyaka yakutshanje, bekukho iimbono ezintathu kubunini be-6GHz: Okokuqala, yabele ngokupheleleyo kwi-Wi-Fi. Okwesibini, yabele ngokupheleleyo kunxibelelwano oluphathwayo (5G). Okwesithathu, yahlule ngokulinganayo phakathi kwezi zibini.

Njengoko kunokubonwa kwiwebhusayithi yeWi-Fi Alliance, amazwe aseMelika ubukhulu becala abele i-6GHz yonke kwi-Wi-Fi, ngelixa iYurophu ingqiyame ekwabeni isahlulo esisezantsi kwi-Wi-Fi. Ngokwemvelo, inxalenye ephezulu eseleyo iya kwi-5G.

Isigqibo se-WRC-23 sinokuqwalaselwa njengesiqinisekiso sokuvumelana okusekiweyo, ukufezekisa i-win-win phakathi kwe-5G kunye ne-Wi-Fi ngokukhuphisana kunye kunye nokuvumelana.

Nangona esi sigqibo sinokuthi singabi nampembelelo kwimakethi yase-US, ayithinteli i-6GHz ekubeni ibe yibhendi yehlabathi jikelele. Ngaphaya koko, ukuphindaphindeka okuphantsi kwesi sibhanti kwenza ukuba ukufikelela ngaphandle kufane ne-3.5GHz kungabi nzima kakhulu. I-5G iya kuzisa iliza lesibini lencopho yokwakha.

Ngokwengqikelelo ye-GSMA, eli gagasi elilandelayo lokwakhiwa kwe-5G liya kuqala ngo-2025, liphawula isiqingatha sesibini se-5G: 5G-A. Sijonge phambili kwizinto ezimangalisayo eziza kuziswa yi-5G-A.

IConcept Microwave ngumvelisi oqeqeshiweyo wamacandelo e-5G/6G RF e-China, kubandakanya isihluzo se-RF lowpass, isihluzo se-highpass, isihluzo se-bandpass, isihluzo se-notch / i-band stop filter, i-duplexer, isahluli samandla kunye ne-coupler eyalathisayo. Zonke zinokulungiswa ngokweemfuno zakho.
