1. IEEE802.11b uye IEEE802.11g ose anoshandiswa mu2.4GHz frequency band. Ngatitsanangurirei maprotocol maviri aya nenzira inoenderera kuitira kuti tinzwisise zviyero zvemaprotocol akasiyana.
IEEE 802.11b chiyero chewaya dzenzvimbo nharaunda network. Yayo inotakura frequency ndeye 2.4GHz, uye inogona kupa akawanda ekufambisa kumhanya kwe1, 2, 5.5, uye 11 mbit/s, kusvika 11 mbit/s. Nguva yekuburitsa yakakurumidza kashanu kupfuura iyo IEEE 802.11 yakajairwa ichangobva kutenderwa makore maviri apfuura, iyo yakawedzera nzvimbo yekushandiswa yematambo enzvimbo isina waya uye yakapa rubatsiro rwekutanga kune yakakwira mareti ekutapurirana. Mukushandiswa, mabhendi akasiyana e5.5 Mbps, 2 Mbps, uye 1 Mbps anogona kushandiswa maererano nemamiriro chaiwo. Mushure mekuyedzwa chaiko, kumhanya chaiko kwekushanda kungangoita 5 MB/s, inenge iri padanho rakafanana neyakajairwa 10Base-T tambo LAN. MuISM bhendi ye2.4GHz, kune gumi neimwe nzira ine bandwidth ye22mhz iripo, ari gumi nerimwe anopindirana mabhendi. Mutevedzeri mwero kuIEEE 802.11b iIEEE 802.11g.
2. IEEE 802.11g yakagamuchirwa muna July 2003. Mutakuri wefrequency ndeye 2.4GHz (yakafanana ne802.11b), uye kune 14 frequency bands. Iyo yepakutanga kutapurirana kumhanya ndeye 54 Mbit/s, uye mambure ekufambisa kumhanya anenge 24.7 Mbit/s (zvakafanana ne802.11a). Iyo 802.11g mudziyo inodzika pasi inoenderana ne802.11b.
Kubva ipapo, vamwe Wirelessroutervagadziri vakagadzira miyero mitsva yakavakirwa paIEEE 802.11g chiyero kuzadzisa zvinodiwa nemusika uye vakawedzera theoretical transmisheni yekumhanya kusvika 108 mbit/s kana 125 mbit/s. Parizvino, kune maprotocol ekutevera akadai seIEEE 802.ax anosanganisira WiFi 6 kana pamusoro, ayo ose akagadziridzwa muPHY layer kuti awedzere kumhanya kusvika kupfuura Gigabit, saka hatizoakurukure pano.
Mufananidzo unotevera ipfupiso yeIEEE802.11a IEEE802.11b IEEE802.11g:
Zviri pamusoro ndiyo tsananguro yeruzivo yeIEEE 802.11b/IEEE 802.11g yakaunzwaShenzhen HDV Phoelectron Technology Co., Ltd. Ndinovimba chinyorwa ichi chinogona kukubatsira iwe kuwedzera ruzivo rwako. Kunze kwechinyorwa ichi kana iwe uchitsvaga yakanaka optical fiber yekutaurirana michina yekugadzira kambani yaungafunganezvedu.
Zvigadzirwa zvekutaurirana zvinogadzirwa nekambani zvinovhara:
Module:optical fiber modules, Ethernet modules, Optical fiber transceiver modules, Optical fiber access modules, SSFP Optical modules,uyeSFP optical fibers, nezvimwewo.
ONUchikamu:EPON ONU, AC ONU, Optical fiber ONU, CATV ONU, GPON ONU, XPON ONU, nezvimwewo.
OLTkirasi:kuchinja OLT, GPON OLT, EPON OLT, kutauriranaOLT, nezvimwewo.
Izvo zviri pamusoro zvigadzirwa zvinogona kutsigira akasiyana network mamiriro. Kune zvigadzirwa zviri pamusoro, nyanzvi uye ine simba R & D timu yakapetwa kuti ipe rutsigiro rwehunyanzvi kune vatengi, uye inofunga uye inyanzvi bhizinesi timu inogona kupa emhando yepamusoro masevhisi evatengi 'kutanga.consultationuye gare gare kushanda.
