Chii chakasiyana 3G 4G uye chii kusarudza?

Our upenyu riri kuwedzera uye mashoko ari nekuumbanidzwa mhepo ose zuva. Nhasi, vanhu vashoma kugutsikana, saka kuti kushandisa serura chete kuti ugare uchiziva, uye ikozvino wose anoda kuti zvakazara yaisanganisira mune ruzivo nzvimbo. Dzevakurukuri, network, mavhidhiyo - nemazango zvose izvi zvinoda kuti munhu zvachose kubatana kuti Internet. Yakachengeteka zvachose kuwana pomumbure zviri nyore, kunyange zvakachipa chaizvo dzenhare mienzaniso mapindire kuburikidza mucheto uye GPRS. Uye kana isu nezvazvo mukuru-nokukurumidza kubatana, ipapo zvose zviri zvakaoma, sezvo pane sarudzo. Uye nguva dzose kunorwadza.

Primary zvinyorwa

Nyore uye inonyanya nzira kuitira pachako Mobile Internet chinhu Mobile nvidia mureza GPRS, pamuuyo uye 3G. Last haagoni kunzi mwero. Ichi seboka izwi kuti inovanza chine mitemo. Kana mudziyo une rutsigiro 3G, 4G, zviri kupa muridzi wayo Indaneti panguva soro nokukurumidza. Kana chiratidzo akadaro achava nematambudziko, zvokushandisa zviri nyore kuti chinja ane kwokutanga mureza mucheto kana GPRS. Maererano Mobile dzaishandisa, 3G network iri pose pose. Asi tsika zvinoitika haisi kudaro peachy. Pane zvakawanda matambudziko chokuita zvakasiyana-siyana zvinoita, pakati iyo kunyange zororo, zvakasikwa , uye zuva chokupfeka. Usati funga pamusoro musiyano pakati 3G kubva 4G, unofanira kunzwisisa zvakasiyana-siyana nuances.

pakawanda

3G-Indaneti pari vakawanda musiyano wezvinyorwa, saka 99% of zviumbu vari kushanda pamwe pomureza uyu. Munguva yapfuura, Mobile Internet ndiyo nyore nzira nokuisa muchikwama, uye ikozvino dzaishandisa vakagadzirira kupa vatengi ayo akasiyana-siyana mutero zvirongwa.

Kana isu kutaura pamusoro musiyano pakati 3G kubva 4G, chinhu chinokosha, oddly zvakakwana, pane kumhanya. The zvikuru nhamba vanhu chokuita kuti mugero, duku achava kwayo bandwidth. Kana isu kuwedzera ichi zvakaoma dambudziko nhau nzvimbo, kubva yokungotaura nokukurumidza inogona dzaona chete pazuva rechitatu. Zvisinei, ichi ichokwadi chete munzvimbo rurefu arambe achirema kuti subscribers - nokuti munzvimbo dzine vanhu vakawanda uye maguta, uyewo kana uchityaira. Mune mamwe mamiriro, mwero dzimwe nguva akasvetuka kuti vanyore tsika.

vamwe mikana

Tisati tataura pamusoro musiyano pakati 3G kubva 4G, tinofanira kufunga vaitaura pamusoro dzaishandisa kushanda pamwe CDMA mureza. The chaizvo ruzivo urwu kunosanganisira yakasiyana zvachose pakugadzirisa dambudziko inoshandiswa mutoro uye uwandu vanoshandisa. Quality uye Kuwanikwa chiratidzo kuvimba, sezvo dzimwe nguva, zvakasiyana-siyana. Asi zvakadaro, nhamba iyi uchishandisa CDMA zvemichina zviri nani zvikuru pane GSM kushandiswa. Under akanaka ezvinhu kufadza nokukurumidza zviri 3.2 megabits muzana wechipiri.

Zvinokosha kucherechedza kuti 3G routers, 4G, CDMA haasi sezvo paiva kushandisa GSM. Zvisinei, kana zvaaida, uye pano unogona kuwana mudziyo "yenyu" kuti achava yakakunakira kuti kushandisa.

LTE samambure

imi nesu pamusoro chii akasiyana 3G 4G pamberi munoudza, zvinofanira pamusoro LTE network, dzakanga akatanga ichangobva kubudikidza dzaishandisa anoverengeka Russia. Munyika, mureza uyu wave uchishanda kwemakore. Dambudziko vachishandisa network idzi Russia iri chokwadi kuti vezvikwata zvose vatorwa anoshanda nenzira yakasiyana zvachose Frequency siyana. Asi dzaishandisa Russian kupa vatengi vavo kusarudza zvakarurama midziyo nokuda achiputa network zvakadai, uyewo Zvakanyanya Kunaka Panguva Yepamuviri mutero kuronga uye zvakanakisisa nhau. Users vanogona kusarudza kubva siyana mano zvakaoma, kusanganisira USB-modems uye Wi-Fi-routers pamwe pakuvara rechargeable bhatiri kuti zvingaonekwa akaisa muhomwe uye kwete kunetseka kuti rwendo vachava nezvinetso Indaneti. Pane mwero routers anogona chokuita simba guta zvegore uye kushandisa kumba.

4G samambure nhau

Saka musiyano pakati 3G kubva 4G? Zvinokosha kucherechedza kuti emimbure miviri vane yakajeka nhau nzvimbo. Kana yechipiri, dambudziko ndiro yakaderera kuwanda pomumbure, kazhinji, shandisa 4G chete mumaguta makuru. MuMoscow uye nharaunda yacho Moscow richakufukidza ichiparara. The wokutanga dzaishandisa kuva itsva mhando unhani, musika akaenda "megaphone". Uye ikozvino ane kunonyanyisa nhau nzvimbo yose Russian ndima. Zvakakosha kunzwisisa kuti 3G / 4G nokuchinja kunoitika zvishoma nezvishoma, uye saka nhau nzvimbo pachamera pamwe nguva. Nzvimbo imwe neimwe Mobile opareta nguva dzose ane akakodzera mashoko pamusoro nhau yacho.

The kambani "MTS" muMoscow uye Moscow nharaunda akaita yakasimbiswa kechipiri nzvimbo kumugumo, iyo yakaitwa zvibvire nokuda vanoshingaira kukura pemambure. Shoma nzvimbo nokuda opareta "Beeline", sezvaakanga chaibatanidzwa "rudzi" pashure zvose.

mutengo

Saka, kusafanana 3G kubva 4G ndiyo nzira Implementation, asi mutengo - ichi ndechimwe chinhu chinokosha kune vose network. 4G havukavu haringorevi maererano foni opareta, uye zvinoenderana sei akatakudza pomumbure panguva. The mushandisi anogona kuwana chero mutero plan, apo kukosha kwayo kuchaita kuvimba iripo bandwidth.

midziyo

Wireless 3G kana 4G-Internet anoshumira rinogona kutsiva the wired Indaneti. Izvi ndezvechokwadi kunyanya apo the wired basa rinobatsirwa havasi kuwanika. Somuenzaniso, kana uine sedumba kana mufurati muchivako chitsva, iwe kuwana yakanaka kumhanya Indaneti iwe haakuvadzi. Pakadaro, yakanakisisa yokupedza ndiko kushandisa 3G kana 4G-router. Zvichava kubatsira kwete chete nokuti sangano iri kuparadzirwa Wireless Internet Wi-Fi, asiwo kuwana mudanga Indaneti, apo mabiko mureza hazvinyatsozivikanwi. Kuti aite izvi, kushandisa kanyanga zvokunze kana kanyanga gudzazwi.

Chii 3G?

3G - a Wireless Michina rakanakira zvakawanda achimuenzanisa kumarudzi adarika. Zvimwe zvinhu kuti musiyano, kunyanya, mukuru-kumhanya yedzimudzangara, yepamusoro nezvaanogona nokuti Multimedia, uyewo yose kungomberereka. Michina iyi inoshandiswa kubatanidza maserura Indaneti kana vamwe network IP anotsanangura kuti vatengi vaiva nomukana inzwi kana mavhidhiyo muchikurukurirana, uyewo kushandisa Indaneti uye kudhanilodha mafaira.

Chii 4G?

Kana isu nezvazvo 3G Kusiyana 4G, zvino, chokwadi, chikuru chokuratidza kuti ekupedzisira anoshandisa itsva mwero kakawanda chikuva, saka hapana shure kugarisana michina. 4G nechinangwa kupa nzwisisika kuchengeteka vose IP-yakavakirwa (IP-nvidia, uchitamba mutambo mabasa, Broadband Internet mukana, uye kumhanyira Multimedia kugutsikana).

4G uye 3G

Kuti tinzwisise kusiyana izvi ruzivo maviri nani zvakafanira kufunga dzimwe pfungwa.

Pfungwa kuenzanisa rokutanga chairo iri nokukurumidza. Pane asingarambiki kunzi mureza, inova nani. Muchiitiko chokutanga, sezvambotaurwa, mwero iri zvakananga novimba pemambure nhau. 4G anoshanda 10 nguva nokukurumidza zvichienzaniswa 3G. Zvose zvinoenderana midziyo yaishandiswa nokuda amplification kuti zviratidzo uye mashoko.

VeMubatanidzwa 3G kwakaita vanoshandisa kuti inzwi foni uchatamisa mashoko ari kumhanya. Kana yakawedzera pamwe 4G yedzimudzangara nokukurumidza zvikuru, mukuwedzera kune izvozvo, vatengi vaikwanisa kushandisa Multimedia tigutsikane zvakananga kubva Internet uye mitambo paIndaneti. Dana mabasa uye mashoko iyi uye pane imwe nyaya, basa panguva iyoyo.

Michina chinja

3G anoshandisa date nokuchinja migero samambure nodes, uye package. chete packet nokuchinja kushandiswa 4G. Kana iwe enzanisa mashoko throughput vose network, musingadi kunzwa chero musiyano. The 4G zvose zvinoda kushandisa IP-nvidia, zvisina kubatsira 3G.

Vose samambure date kuchinjirwa mwero iri pamusoro chete, uye pachiyero 5-20 Mbit / s.

mhedziso

Chokwadi, 4G rinomiririra kupfuura michina yemhando yepamusoro, asi ayo Implementation yakazara asati apera, saka vanoona havagoni Makomborero. Sezvo rutsigiro 3G, 4G haisati yakatanga zvakakwana kuenda pane inotevera pamwero, zvose yemabasa kuti kunofanira kuwanikwa vanoshandisa, vari vachiri padanho Implementation. ichangobva chizvarwa pomumbure vane zvakawanda uremu zvinhu zvisina zvakazara kuongororwa, uye ano midziyo zuva roga roga hunowedzera yakaoma, saka zvose zvakanakira mabikirwo vachava pachena chete pashure pechinguva, uye ipapo tinogona enzanisa 3G uye 4G-Internet zvakazara.
