UMphathiswa wezoShishino noLwazi lweTekhnoloji umisele ngokusesikweni izicwangciso zokususa ibhendi ye-840-845MHz kuluhlu lweefrikhwensi ezigunyazisiweyo zezixhobo zokuchongwa kweRadio Frequency, ngokutsho kwamaxwebhu omthetho asandul’ ukukhutshwa. Esi sigqibo, esifakwe kwiMithetho yoLawulo lweRadio ye-900MHz Band Frequency Identification Equipment, sibonisa indlela yaseTshayina yokwenza ngcono izixhobo ze-spectrum ukulungiselela ubuchwepheshe bonxibelelwano besizukulwana esilandelayo.

Abahlalutyi beshishini baphawula ukuba utshintsho lomgaqo-nkqubo luchaphazela kakhulu iinkqubo zeRFID ezikhethekileyo ezikude, njengoko uninzi lwezicelo zorhwebo sele zisebenza ngaphakathi koluhlu lwe-860-960MHz. Ixesha lotshintsho livumela ukuphunyezwa kancinci kancinci, kunye nezixhobo ezikhoyo eziqinisekisiweyo ezivunyelwe ukuqhubeka nokusebenza kude kube sekupheleni kobomi. Ukuthunyelwa okutsha kuya kuthintelwa kwibhendi eqhelekileyo ye-920-925MHz, enika amandla aneleyo kwiimfuno zeRFID zangoku.

Iinkcukacha zobugcisa ezihamba nomthetho zimisela iimfuno ezingqongqo ze-bandwidth yetshaneli (250kHz), iipateni zokutsiba rhoqo (ubuninzi bexesha lokuhlala lemizuzwana emi-2 ngetshaneli nganye), kunye nomlinganiselo wokuvuza kwetshaneli ekufutshane (ubuncinci be-40dB kwitshaneli yokuqala ekufutshane). La manyathelo ajolise ekuthinteleni ukuphazamiseka kweebhendi zefrikhwensi ezikufutshane ezisasazwa ngakumbi kwiziseko zonxibelelwano eziphathwayo.

Uhlengahlengiso lwefrikhwensi lulandela iminyaka yokubonisana neengcali zobugcisa kunye nabathathi-nxaxheba kushishino. Amagosa olawulo akhankanya izizathu ezintathu eziphambili: ukuphelisa ukwabiwa kwe-spectrum engafunekiyo ukuze kusetyenziswe izixhobo ngokukuko, ukucoca i-bandwidth yezicelo ezintsha ze-5G/6G, kunye nokuhambelana neendlela zokumisela i-RFID frequency zamazwe ngamazwe. Ibhendi ye-840-845MHz yayiyeyona nto ibalulekileyo kubaqhubi beenkonzo zonxibelelwano ukwandisa iinkonzo zabo.

Ukuphunyezwa kuya kwenzeka ngezigaba, kunye nemithetho emitsha eqala ukusebenza ngoko nangoko ukuze kufunyanwe izixhobo zexesha elizayo ngelixa kuvumela ixesha elifanelekileyo lotshintsho kwiinkqubo ezikhoyo. Ababukeli bemarike balindele ukuphazamiseka okuncinci, njengoko uluhlu lweefrikhwensi ezichaphazelekayo lumele icandelo elincinci kuphela lokufakwa kweRFID iyonke. Uninzi lwezicelo zoshishino kunye nezorhwebo sele zithobela umgangatho we-920-925MHz osagunyazisiweyo.

Uhlaziyo lomgaqo-nkqubo lukwacacisa iimfuno zesatifikethi, lugunyazisa ukuvunywa kohlobo lwe-SRRC (State Radio Regulation of China) kuzo zonke izixhobo ze-RFID ngelixa lugcina udidi olukhulula ezo zixhobo kwilayisenisi yesitishi ngasinye. Le ndlela ilungeleleneyo igcina ulawulo olulawulayo ngaphandle kokudala umthwalo wolawulo ongeyomfuneko kumashishini asebenzisa izisombululo ze-RFID.

Xa sijonge phambili, amagosa e-MIIT abonisa izicwangciso zokuqhubeka nokuhlolwa kwemigaqo-nkqubo yokwabiwa kwe-spectrum njengoko iteknoloji ye-RFID itshintsha. Ingqwalasela ekhethekileyo iya kugxila kwizicelo ezivelayo ezifuna uluhlu olubanzi lokusebenza kunye nokuhlanganiswa okunokwenzeka kunye nobuchule bokuqonda okusingqongileyo. Umphathiswa ugxininisa ukuzibophelela kwakhe kwiinkqubo zolawulo lwe-spectrum ezixhasa zombini ubuchule bobuchwepheshe kunye nophuhliso lweziseko ezibalulekileyo.

Iingqwalasela zokusingqongileyo nazo ziye zanefuthe kwicala lomgaqo-nkqubo, kwaye ukuhlanganiswa kwamaza ombane kulindeleke ukuba kunciphise ukuphazamiseka okunokwenzeka kwe-electromagnetic kwiindawo ezibuthathaka zendalo. Ukwabiwa okubanzi kuvumela ukujonga ngokufanelekileyo kunye nokunyanzeliswa kwemigangatho yokukhupha umbane kuyo yonke imisebenzi ye-RFID.

Imibutho yezoshishino iyamkele kakhulu ukucaciswa kwemithetho, iqaphela ukuba ixesha elandisiweyo lotshintsho kunye nemigaqo yokuxhasa amashishini ibonisa ukulungelelaniswa okufanelekileyo kotyalo-mali olukhoyo. Amaqela okusebenza kwezobugcisa alungiselela izikhokelo zokusetyenziswa ezihlaziyiweyo ukuze kube lula ukwamkelwa ngokutyibilikayo kumacandelo ahlukeneyo asebenzisa iinkqubo zeRFID okwangoku.

Uhlengahlengiso lwamaza lulungelelanisa isakhelo solawulo saseTshayina neendlela ezilungileyo zamazwe ngamazwe ngelixa sijongana neemfuno ze-spectrum zasekhaya. Njengoko ubuchwepheshe obungenazingcingo buqhubeka buhambela phambili, kulindeleke ukuba olo hlengahlengiso lwemigaqo-nkqubo luqhubeke rhoqo, lulinganise iimfuno zabachaphazelekayo abahlukeneyo kwinkqubo yedijithali edibeneyo ngakumbi.
