Bazi reIndasitiri neTekinoroji yeRuzivo rakagadzira hurongwa hwekubvisa bhendi re840-845MHz kubva pahuwandu hwemafrequency hwakatenderwa hwezvishandiso zveRadio Frequency Identification, zvichienderana nemagwaro matsva emutemo. Sarudzo iyi, yakavakirwa mukati me900MHz Band Radio Frequency Identification Equipment Radio Management Regulations yakagadziridzwa, inoratidza nzira yeChina yekugadzirisa zviwanikwa zvespectrum mukugadzirira tekinoroji yekutaurirana yechizvarwa chinotevera.

Vaongorori vemaindasitiri vanoti shanduko yemutemo inonyanya kukanganisa masisitimu eRFID emhando yepamusoro, sezvo akawanda maapplication ekutengeserana atove kushanda mukati me860-960MHz. Nguva yekuchinja inobvumira kushandiswa zvishoma nezvishoma, nemidziyo iripo yakabvumidzwa kuramba ichishanda kusvika yapera. Kuiswa kutsva kuchagumira kune 920-925MHz band yakajairika, iyo inopa kugona kwakakwana kwezvinodiwa zveRFID zviripo.

Magadzirirwo ehunyanzvi anoperekedza mutemo uyu anotsanangura zvinodiwa zvakasimba zvebandwidth yechiteshi (250kHz), maitiro ekusvetuka-svetuka (nguva yakanyanya yekugara kwemasekonzi maviri pachiteshi chimwe nechimwe), uye zviyero zvekudonha kwechiteshi chiri pedyo (40dB shoma kune chiteshi chekutanga chiri pedyo). Matanho aya anovavarira kudzivirira kukanganiswa kwemabhendi efrequency ari pedyo ari kuwedzera kushandiswa muzvivakwa zvekutaurirana zvefoni.

Kugadziriswa kwema frequency kunotevera makore ekukurukurirana nenyanzvi dzehunyanzvi nevatori vechikamu muindasitiri. Vakuru vezvemitemo vanotaura zvikonzero zvitatu zvikuru: kubvisa kugoverwa kwema spectrum kusingashande zvakanaka kuti zviwanikwa zvishandiswe zvakanaka, kubvisa bandwidth yemashandisirwo ari kubuda e5G/6G, uye kuenderana nemaitiro eRFID frequency standardization epasi rose. Bhendi re840-845MHz rakanga rave rakakosha zvakanyanya kune vanoshanda nefoni kuwedzera mabasa avo.

Kushandiswa kuchaitwa muzvikamu, mitemo mitsva ichitanga kushanda nekukasika kuti pave nekusimbisa michina yeramangwana ukuwo ichibvumira nguva yekuchinja yakakodzera kune masisitimu aripo. Vacherechedzi vemusika vanotarisira kukanganiswa kushoma, sezvo huwandu hwema frequency hwakakanganiswa hwaimiririra chikamu chidiki chekushandiswa kweRFID. Mazhinji mashandisirwo emaindasitiri neemabhizinesi atove achitevedzera mwero we920-925MHz uchiri kubvumidzwa.

Kuvandudzwa kwemutemo uyu kunojekesawo zvinodiwa zvechitupa, zvichiraira mvumo yemhando yeSRRC (State Radio Regulation of China) yemidziyo yese yeRFID ukuwo zvichiramba zvichiisa muganho unosunungura michina yakadaro kubva pakupa marezenisi echiteshi chega chega. Maitiro aya akaenzana anochengetedza kutarisirwa kwemitemo pasina kugadzira mutoro usingakodzeri wekutonga kumabhizinesi anoshandisa mhinduro dzeRFID.

Vachitarisa mberi, vakuru veMIIT vanoratidza zvirongwa zvekuenderera mberi nekuongorora mitemo yekugoverwa kwema spectrum sezvo tekinoroji yeRFID ichifambira mberi. Kunyanya kutarisisa kuchatarisa pamashandisirwo ari kubuda anoda huwandu hwakawanda hwekushanda uye kubatanidzwa pamwe nehunyanzvi hwekuona zvakatipoteredza. Bazi rinosimbisa kuzvipira kwaro kune maitiro ekutarisira ma spectrum anotsigira hunyanzvi hwetekinoroji uye kuvandudzwa kwezvivakwa zvakakosha.

Kufunga nezvezvakatipoteredza kwakakanganisawo nhungamiro yemutemo, uye kusanganiswa kwema frequency kunotarisirwa kuderedza kupindirana kwema electromagnetic munzvimbo dzinonyanya kugadzikana dzezvakatipoteredza. Kugoverwa kwakawanda kunobvumira kutarisa nekusimbisa mitemo ye emission mumabasa ese eRFID.

Masangano eindasitiri akagamuchira zvikuru kujeka kwemitemo, achitaura kuti nguva yakareba yekuchinja uye zvigadziro zvekutanga zvinoratidza kuenderana kwakakodzera kwekudyara kuripo. Mapoka ebasa rehunyanzvi ari kugadzirira nhungamiro dzekushandisa dzakagadziridzwa kuti dzibatsire kugamuchirwa zvakanaka muzvikamu zvakasiyana-siyana zviri kushandisa masisitimu eRFID parizvino.

Kugadziriswa kwema frequency kunoenderana nehurongwa hwemitemo yeChina netsika dzepasi rose ukuwo uchitarisa zvinodiwa neinternet spectrum. Sezvo matekinoroji asina waya achiramba achifambira mberi, kugadziriswa kwemitemo kwakadaro kunotarisirwa kuwanda, zvichienzanisa zvinodiwa nevane chekuita nedhijitari vari kuramba vakabatana.
