Inokurumidza, yakakwirira, yakasimba ndiyo motto yeOlympic, iyo inonyanya kukosha kune zvigadzirwa zveIT zviri kugadzirwa nhasi. Imwe neimwe itsva redhiyo yekutaurirana mwero yakaunzwa inowedzera kuwedzera huwandu hweruzivo rwunofambiswa, inoderedza network latency, uye zvakare inounza akawanda anobatsira magadzirirwo ayo asingawanzo kujeka kune yekupedzisira mushandisi wesevhisi. Nhasi, sekuratidzira kunoratidza, kusvetuka mumhando dzemhando dzemaserura network, kubva kuchizvarwa chekare kusvika kune chitsva, chinogona kutsanangurwa sekufambira mberi kwejometri. Saizvozvo, isu takatogadzira tarisiro yekuti chiyero chitsva chimwe nechimwe chinofanirwa kuita zvakapetwa kakawanda pane chiripo. Kumirira kwakakodzera. Mukurangarira kwedu, kuiswa kwe2-3-4G tekinoroji, kutaura zvazviri, kwaive kubudirira kwakadaro, asi ko 5G?
Tichiuya neakasiyana-siyana ezvinyorwa munhau, pamwe nekukurukura pakati peshamwari mishumo yekukunda yevafambisi venhare nezve kugadzirira kuvhura 5G kutaurirana, vazhinji vedu tinongofungidzira tarisiro dzinoshamisa. Nehurombo, pamusoro pekukunda kupenya kwepamusoro kweIT, mitsva yekutaurirana isina waya zvakare ine misungo yavo, yatisingagari tichifunga nezvayo. Mamiriro ezvinhu akawedzerwa nenyaya yekuti kubuda kwehunyanzvi hutsva hwetiweki hunogona kukwikwidza kwete kwete chete mitemo yefizikisi, asiwo kusada kwevanhu kubhadhara kugadzirwa kwemanetiweki aya, sezvo isingaone kukosha kweizvi. mikana mitsva panguva ino. Ndiko kusanzwisisika kwe5G tekinoroji yaticharamba tichitaura nezvayo.

Kuzadzikiswa kwakazara kweiyo 3G yekutaurirana mwero kungave kusiri kunakidza uye kunakidza sezvazvaive ne2G, zvisinei, pasina mubvunzo yakava chiitiko chitsva kwatiri tose. Kuenzanisa 3G neyakatangira, zvinogona kucherechedzwa kuti iyo chaiyo yekumhanyisa, zvese zvekurodha uye kurodha, yakawedzera kagumi! Pamusoro pekuwedzera kunoshamisa kwekukurumidza, takagamuchirawo kuderedzwa kwetiweki latency kune yakagadzikana 50 ms, yaive yakarongeka yehukuru huri nani pane 2G ine 200+ ms. Nekuuya kwechizvarwa chechitatu chekutaurirana kwemafoni, nharembozha yeInternet yakazopedzisira yave imwe nzira yemakwikwi kune mumwe wayo ane waya.
Kana iri 4G, yakashamisa kunyange yakaderera pane yakatangira. Hongu, hongu, nekuuya kwechiyero chitsva, Indaneti yakatowedzera "kukurumidza", mitambo yakatowedzera kukwanisa. Panguva imwecheteyo, kubva pakuona kwekubudirira kwekutengeserana, 4G yakave chinhu chisingaverengeki chekutorwa kwevafambisi venhare; vafambisi vanoipa munyika dzichiri kusimukira vakawana kudzoka kwakashata pabasa. Iyo denga-yakakwira kumhanya kwe4G, mune dzidziso inosvika 1 Gbit/s, ichiri kungoita kuti mutengi anyemwerere. Iyo inonyanya kufarirwa paramende yekushandiswa kwakajairika kweiyo chiyero kuvepo kwenhamba yakakwana ye4G base zviteshi. Mumakore mashanu apfuura ebudiriro, kufukidzwa kwe5G muGermany yakabudirira, France, neBritain kwakafukidza vanhu vangangosvika 4%, asi pasi rose izvi ndizvo zvakasarudzika kwete mutemo. Kana isu tikatotora iyo post-Soviet nzvimbo, tinogona kuona kuti 99G ichiri padanho rekudyara uye kuita. Pamusana peizvi, chii chakamirira 4G?

Frequency ruzhinji
Muchokwadi, kusvetuka kukuru kwakaitika kubva ku1G kuenda ku4G network kwakaitwa mukati memiganhu yeimwe tekinoroji maitiro. Imwe neimwe inotevera "G" iri, yakati wandei, shanduro yemazuva ano yeyakatangira. Izvi, kazhinji, hazvishamise kunzwisisa zvinotitungamira kuti tinzwisise mamiriro azvino - isu tiri pedyo zvakanyanya nemiganhu yetekinoroji yatinoshandisa iyo iri pasi pemazuva ano cellular network. Kuwedzera kweamplitude yechiteshi chekufambisa uye nzira itsva dzekugadzirisa zviratidzo zvakatipa mukana wekuwedzera huwandu hwemashoko anoparadzirwa pane imwe nguva, asi mune ramangwana kuwedzera kukuru kwekumhanya kwetiweki kunokwanisika chete kuburikidza nekuwedzera kukuru iyo frequency yekushandisa, uye izvi zvakazara nemhedzisiro.
Kufungidzira kwehuwandu hwezviteshi zvepasi kuvhara 100% yedunhu reUkraine zvichienderana nekushanda kwavo
Chokwadi ndechekuti, zvinoenderana nekosi yefizikisi yechikoro, sezvo aya mafrequency anowedzera, kudzikisira kwavo kunowedzerawo zvakanyanya, uye nekuwedzera, kugona kwekupinda kwemafungu eradiomagnetic kunodererawo.

Imwe nzira kune yakakwira ma frequency inogona kunge iri kuiswa kwe5G pa low frequencies, kusvika ku 1 GHz, izvi zvichaita kuti zvikwanise kupa yakazara kufukidzwa kwenzvimbo dzakakura, asi mune iyi mamiriro, mushandisi wepakati haazonyatso cherechedza chero shanduko mukushanda. yegadget yake, kubva ku4G yaanotoziva nayo. Nekuda kweizvozvo, 5G njodzi yekuva musoro kune vatengesi, kuve neimwe hwaro yeramangwana riri kure, inotakura zvakadzika mabhenefiti, toti, kune iyo LoT nyika, asi mushandisi weruzhinji zvakajeka haazobhadhare.
Ko kana?
Kana 5G iri mukwikwidzi kune 4G pane yakaderera frequencies, saka zvine musoro kufunga kuti chiyero chitsva chichatangwa pamafrequency e5 GHz uye kumusoro. Chokwadi, zvinoenderana neiyo chiyero chitsva, inogona kutangwa pamafrequency kusvika ku300 GHz. Asi pano tinosangana nechipingamupinyi chitsva: kushandiswa kwemamilimita wave neserura kunopa kukakavara nemukwikwidzi nenzira yeWiFi tekinoroji.
WiFi yanga iri muvengi wekare kune mobile operators. Kutora goridhe zvinoreva pakati pemutengo we "wired" megabyte uye nhanho yekufamba, yakazvisimbisa zvakasimba mudzimba dzedu, mahofisi, kutakura uye kunyange mapaki. Kuve nemisimboti yekutepfenyura isina waya data yakafanana ne5G, tekinoroji yeWiFi yakatevera nzira yayo yebudiriro uye yakagara yakavimbika niche yayo yakasarudzika kusvika nguva pfupi yadarika.
Kutaura chokwadi, mamiriro ezvinhu neIT kutaurirana agara ave asina musoro, uye hechino chinhu. Hazvina kujeka kuti ndiani akatanga kupinda mubindu raani - vanopa Internet vane yavo IP telephony kune cellular operators, kana vashandisi vane yavo 2-3-4-5G vakatanga kubvisa Internet traffic kubva kune vadiki vanopa, asi ikozvino pane kupesana kwechido. Vafambisi venhare vakanyatsova vapeji veInternet, vapeji veInternet vakaramba vari vapeji veInternet, asi panguva imwecheteyo vakaramba vari vateveri vezvakati siyanei network yekuvaka. Muchidimbu, takaona shanduko inoshanduka muIT. Kana tikafunga iyo yakashandiswa 5G mwero kwete kubva pakuona kwekuchinja kwechizvarwa che4G, icho chinofanira kupedzisira chatsiva, sezvakaitika chaizvo ne2-3G kare, asi idaidze, taura, muurayi weWiFi? Muchiitiko ichi, zvakawanda zvekusawirirana uye zvisinganzwisisiki zvinosanganiswa ne5G zvingave zvinonzwisisika uye zvinotora nzvimbo yavo mumaketani ane musoro.

Nzira dzeInternet dzatinokwanisa kutaurirana nenyika dzese dzakafanana kune hombe nharembozha uye diki imba ine waya yeInternet inopa. Bhizinesi kune vese vanotanga padanho remutengi-mupi. Iwe neni tichasvika sei paWorld Wide Web uye kune bhizinesi remabhiriyoni emadhora rakabikwa pahunyanzvi hwakasiyana, michina, uye mhando. Mamiriro ezvinhu patinoshandisa nzira mbiri dzakasiyana dzekuronga kupinda paInternet zvakambove zvine musoro, uye sezviri pachena izvi hazviperi mangwana, asi nyika iri kuedza kurerutsa. Kuramba kushandisa masevhisi evapeji vekare kuchave mhedzisiro yemakambani kugadzira nzira dzepasirese dzekuwana iyo Internet kuburikidza neuniversal cellular network. Wese kutaurirana mamodule, epasirese "akareruka" gadget kubva isina kutaurwa WiFi, Bluetooth, LAN zvikamu. Kudzoreredzwa kwepakati kurongeka nesangano rekuvhara, kubviswa (kuderedzwa kwakanyanya) kweredhiyo frequency kusvibiswa mumahofisi, kunyanya zvivakwa zvemafurati, zvichabatsira mutengi wekupedzisira. Zvakaipa chaizvo here? Pamwe inguva chaiyo yekuita iyi qualitative kusvetuka?
Vamwe vangati izvi zvese hazvina musoro, vanoti WiFi inotevedzera nzira yayo yekuvandudza uye ine seti yakanakira seti yezvimiro zvisingaite kuti ingofa. Zvichida zvakadaro, pamalaptops matsva iwe unogona kuwana zvese zviri zviviri Bluetooth uye RJ-45 kubuda, asi zvishoma uye zvishoma kazhinji. Zvavakaitwa neWiFi pane imwe nguva .
Nekuvandudzwa kwezviitiko izvi, pane chinhu chimwe chete chekutya: kana WiFi ikava anachronism uye yakawanda ye geeks, isu hatingawire muhuremu hwehupenzi hwevakawanda monopolistic operators? Tichanyatso kurangarira zvakare avo vakakanganwa sehope dzakaipa: kubhadharisa kwesekondi yega yega IP telephony, "bhiza" mutero pa megabyte, kutenderera uye zvimwe zvinofadza? Mibvunzo yose iyi zviri pachena kuti ndeyamangwana, asi hatifaniri kukanganwa kuti nhasi izuva razuro, uye iwe neni tiri zvapupu zvacho.
