HSPA inovaka pahutano hwe 3G kuti ipe zvakakurumidza kukurumidza
HSPA + ndeimwe yezvinyorwa zvakawanda zvinotsanangura kufambisa kwekombiyuta yefoni yako. Taura zviri nyore, HSPA + inonzi 3G network inogadzirisa kuparadzaniswa pakati pe 3G ne 4G .
Vamwe vatengesi vekutengeserana nevatengi vakanyora zvisina kukodzera HSPA + sekuzara 4G, asi izvi zvinotsausa.
HSPA + inoreva kuti "Evolved High Speed Packet Access" (inonziwo HSPA Plus) uye inyanzvi yehutachiona yehutabhenji, yakakwanisa kudhinda kuwedzerwa kwemashoko kusvika ku 42.2 megabits nechipiri (Mbps).
Zvisinei, izvi zvinorevei kune vatengi? Ngatitarise pamitambo yefodya uye nekukurumidza kwavo zvishoma nezvishoma kuona kuti izvi zvinogona kukukanganisa sei.
Nhoroondo Pfupfupi yeMasitiramiro eMitemo Maitiro
Nhoroondo yekutengesa mitambo isina mhepo inodzokera kumashure 1G muna 1981, yakaenzaniswa neanalog-chete yakareba kare kusati kwauya mafoni efoni yakabvumira nyore nyore foni chete.
Sezvo "G" inongoreva "chizvarwa," 1G haina kudanwa iyo kusvikira 2G yakabuda muma1990, ichitsigira dijitri inzwi uye kutumira mameseji.
2G Networks
Mamiriyoni 2G akanga achiri kunyanya-akafanana ne14.4 Kbps (kilobiti pamusi wechipiri). Iyi mitemo yakasimbiswa kuma1900 nechekupedzisira neGPRS (General Packet Radio Service), ichiwedzera kukwanisa kwechigadziro chekuwana "nguva dzose" yekutengesa dhepfenyuro nemafuta ekukomberedza 40 Kbps, kunyange vatengesi vakaitengesa pa 100 Kbps.
Sangano re 2G rakasimbiswa neGPRS dzimwe nguva rinotumidzwa senhare ye 2.5G.
Kutevera GPRS yaiva EDGE (Enhanced Data-rates ye GSM Evolution), yakakurumidza kupfuura GPRS asi ichiri kushingaira kuti ipedze kuchizvarwa chinotevera cheGG 3G, ichiwana moniker ya 2.75G. MaPhones ekutanga, semuenzaniso, aikwanisa kubuda kweEEDGE, iyo yaive inenge 120 Kbps kusvika ku 384 Kbps.
3G Networks neHSPA
Nekuuya kwehutano hwe 3G muna 2001, ma-smartphones akazotanga kubvisa, sezvo kufamba kwekuwedzerwa kwemashoko kwakapedzisira kuputsa kwete megabit chete pamusana wechipiri, asi yakakurumidza kusvika kusvika 2 Mbps. A device 3G-inoenderana nokukurumidza zvokuti Apple akatumidza zita rake foni iPhone 3G. Uye pano ndipo pane HSPA inopinda.
HSPA (kunze kwe "plus") inosanganiswa nemitemo miviri: High Speed Downlink Packet Access (HSDPA) uye High Speed Uplink Packet Access (HSUPA) - iyo inongoreva chete kuti iyo inonyorerwa uye inokwidza mavhesi ekuvakwa kwepakuvamba ye 3G ye peak data yezinga re 14 Mbps pasi uye 5.8 Mbps kumusoro.
HSPA + yakabva yatangwa muna 2008, uye dzimwe nguva inonzi 3.5G. HSPA + yakasimudzirwa 3G pamwe nekuwedzera kwepamhanho yezvikwata zve 10 Mbps, uye chaiyo-nyika inomhanya yakawanda kupfuura 1-3 Mbps. Zvakare, dzimwe nhamba dzemagetsi ne 3G HSPA + network dzakatadza kuzivisa kasi yavo se 4G.
Cherechedza : Cherechedza kuti hurukuro yepamusoro yekudhinda data yeHSPA + dzimwe nguva inonzi yakakwirira se100 Mbps, kana ma 4G mavhesi. Izvi hazvina kururama; hauzombofi uine hutsva hwekutsvaira kubva kune HSPA + network (yakakurumidza kusvika 42 Mbps). Izvozvo zvakati, HSPA + ndiyo yakasiyana-siyana ye 3G kunze uko.
4G uye LTE Networks
Iyo mizinga yeG 4G inogona kukurumidza kukurumidza kusvika ka5 nekukurumidza sa 3G uye yakabva paLTE (Long Term Evolution) protocol. Zvechokwadi, kukurumidza kwepamusoro kunofungidzirwa kunofungidzirwa 100 Mbps, kunyange zvazvo kuwirirana nekukurumidza kuchave kwakafanana ne 3 Mbps kusvika 10 Mbps - zvichiri kutsanya zvakanyanya uye hapana chaungazvidza.
Sangano re 4G rinoshanda pane zvakasiyana-siyana kupfuura 3G, saka iva nechokwadi kuti une chipikisi chinokwanisa kuchitora.
5G Networks
5G isiri-ye-yakazara-inoshandiswa isina wireless teknolojia inopa kuvandudzwa pamusoro pe 4G kufanana nekukwira kusvika kusvika gumi zvakapera.
Mitambo inoshandisa HSPA & # 43;
Masoja anoshandisa 3G kana izvo zvakasimbiswa neHSPA + zvinowanikwa munyika yose. Vane nhamba huru huru dzeUnited States (AT & T, Verizon, T-Mobile, uye Sprint) dzose dzinopa 4G LTE network network, zvichienderana nenzvimbo, asi inewo nzvimbo dze 3G kana 3G HSPA +.
Fonikoni Yakagadzirwa ne 3G HSPA
Mukuwedzera kune mafaira data data speed se 3G ne 4G, vatengi vefoni vanofanirwa kunge vachiziva masheji eredhiyo.
Sangano re 3G rinowanzoshanda pane imwe yezvikamu zvishanu - 850, 900, 1700, 1900, uye 2100 - naizvozvo unoda kuva nechokwadi chokuti yako 3G foni inotsigira iyo mafaira (ose mafoni emazuva ano anoita). Nhare dzefoni dzinotsigirwa dzinowanzonyorwa mubhokisi, kana iwe unogona kudana muiti kuti ave nechokwadi.
