HSPA imamanga payezo wa 3G kuti ipereke mofulumira kwambiri
HSPA + ndi imodzi mwa zizindikiro zambiri zomwe zimafotokoza liwiro la intaneti ya intaneti. Mwachidule, HSPA + ndi makina a 3G osakanikirana omwe amachititsa kuti pakhale kusiyana pakati pa 3G ndi 4G .
Ena ogulitsa malonda a pa Intaneti amalankhula molakwika kuti HSPA + ndi 4G, koma izi zikusocheretsa.
HSPA + imatanthauza "Speed Speed Packet Access Access" (yomwe imatchedwanso HSPA Plus) ndipo ili ndi luso lamakina osakaniza opanda waya, lotha kupanga maulendo opita ku 42.2 megabits pa sekondi (Mbps).
Komabe, kodi izi zikutanthauza chiyani kwa ogula? Tiyeni tiyang'ane pa mafoni a m'manja ndikuyenda mofulumira kuti tione momwe izi zingakhudzire inu.
Mbiri Yachidule ya Maofesi Athu Otchedwa Mobile Network
Mbiri ya mafilimu opanda mauthenga opanda waya imabwereranso ku 1G mu 1981, chiwerengero cha analogi-okha pokhapokha kubwera mafoni a m'manja omwe amalola mafoni osavuta okha.
Popeza "G" imangotanthauza "m'badwo," 1G sinaitanidwe mpaka 2G itangoyamba muzaka za m'ma 1990, kuthandizira mau adijito ndi mauthenga.
2G Networks
Mapiri a 2G analibe nkhono-monga 14.4 Kbps (kilobits pa mphindi). Malamulo amenewa adakonzedwa kumapeto kwa zaka za m'ma 1990 ndi GPRS (General Packet Radio Service), kuwonjezera mphamvu yopezera chipangizo cha "nthawi zonse" chingwe chokhala ndi maola 40 Kbps, ngakhale kuti ogulitsa anagulitsa pa 100 Kbps.
Maselo a 2G opangidwa ndi GPRS nthawi zina amatchulidwa ngati makina a 2.5G.
Kutsatira GPRS kunali EDGE (Mapulogalamu Owonjezeka a GSM Evolution), mofulumira kwambiri kuposa GPRS koma osathamanga mokwanira kuti apititse ku mbadwo wotsatira wa 3G, kulandira moniker wa 2.75G. Ma iPhones oyambirira, mwachitsanzo, anali ndi mphamvu za EDGE, zomwe zinali pafupifupi 120 Kbps ku 384 Kbps.
3G Networks ndi HSPA
Pokufika muyezo wa 3G mu 2001, mafoni a mafoni anayamba kutha, monga msinkhu wopititsa deta pamapeto pake sinathyole mzere wa megabit kapena wachiwiri, koma mwamsanga kufika pa 2 Mbps. Chipangizo chokhala ndi 3G chili mofulumira kwambiri moti Apolisi adatcha foni yake iPhone 3G. Ndipo apa ndi pamene HSPA imalowa.
HSPA (popanda "kuphatikiza") ndi kuphatikiza ma protocol awiri: High Speed Downlink Paket Access Access (HSDPA) ndi High Speed Uplink Paket Access Access (HSUPA) - zomwe zimangotanthawuza kuti kumasula kwake ndi kuperekera maulendo kumanga msanga oyambirira 3G tsambali la chiwerengero cha 14 Mbps pansi ndi 5.8 Mbps mmwamba.
HSPA + inayamba kufotokozedwa mu 2008, ndipo nthawi zina imatchedwa 3.5G. HSPA + 3G yowonjezereka m'mipikisano yapamwamba ya 10 Mbps, yomwe ikuyenda mofulumira kwambiri monga 1-3 Mbps. Apanso, zonyamulira zamagetsi ndi makina a 3G HSPA + adalengeza mofulumira liwiro lao ngati 4G.
Zindikirani : Dziwani kuti kuthamanga kwa deta kwapamwamba kwa HSPA + nthawi zina kumakhala kwapamwamba kuposa 100 Mbps, kapena max 4G. Izi sizolondola; simudzapeza mtundu wotentha woterewu kuchokera kumtunda wa HSPA + (msinkhu wake waukulu ndi 42 Mbps). Izo zati, HSPA + ndi mitundu yosiyanasiyana kwambiri ya 3G kunja uko.
4G ndi LTE Networks
Myezo wa 4G ukhoza kuthamanga mofulumira katatu mofulumira monga 3G ndipo umachokera ku protocol ya LTE (Long Term Evolution). Ndipotu, msinkhu waukulu wamtunduwu umatengedwa ngati Mb Mbiti 100, ngakhale mawindo ambiri akhoza kukhala ngati 3 Mbps mpaka 10 Mbps - komabe mofulumira ndipo palibe chomwe chingachititse manyazi.
Maseti a 4G amagwira ntchito yosiyana kuposa 3G, kotero onetsetsani kuti muli ndi chipangizo chimene chingathe kugwiritsa ntchito.
5G Networks
5G ndi makina osayendetsedwa opanda pulogalamu yamakono omwe amapereka patsogolo pa 4G monga mofulumira mpaka maulendo 10 mofulumira.
Mitundu yomwe imagwiritsa ntchito HSPA & # 43;
Mapulogalamu omwe amagwira ntchito 3G kapena omwe akulimbikitsidwa ndi HSPA + amapezeka padziko lonse lapansi. Otsatira anayi akuluakulu a US (AT & T, Verizon, T-Mobile, ndi Sprint) onse amapereka mauthenga a 4G LTE, malinga ndi malo, komanso amakhala ndi 3G kapena 3G HSPA +.
Kugwirizana kwa foni ndi 3G HSPA
Kuphatikiza pa miyendo yapamwamba ya deta ya ma data monga 3G ndi 4G, ogula mafoni amagulu amafunika kudziwa magulu a maulendo a wailesi.
Gulu la 3G limagwira ntchito pa imodzi mwa maulendo asanu - 850, 900, 1700, 1900, ndi 2100 - kotero muyenera kudziwa kuti foni yanu ya 3G imathandizira maulendo (mafoni onse amakono). Maofesi omwe amathandizidwa ndi foni amalembedwa m'bokosi, kapena mungatchule wopanga kuti akhale otsimikiza.
