2.4GWiFi inoshanda mu2.4GHz frequency band, ine frequency renji ye2400-2483.5MHz. Muyero mukuru unoteverwa ndeweIEEE802.11b/g/n mwero wakagadzirwa neInstitute of Electrical and Electronics Engineers (IEEE). Pazasi, isu tinopa yakadzama sumo kune aya zviyero:
• IEEE802.11 inzvimbo isina waya yenharaunda yenzvimbo yakajairwa yakagadziridzwa neIEEE, inonyanya kushandiswa kugadzirisa mawaya evashandisi uye materminals evashandisi muhofisi nekambasi network. Bhizinesi rinonyanya kugumira pakuwana data, uye iyo yakanyanya kumhanya inogona kungosvika 2Mb/s. Nekuda kwekutadza kweIEEE 802.11 kuzadzisa zvinodiwa nevanhu maererano nekumhanya uye kureba kwekutapurirana, tekinoroji iyi ndeyechinyakare.
• Iyo IEEE802.11b chiyero, inozivikanwawo sewireless fidelity tekinoroji, inoshandisa iyo inozivikanwa pasi rose 2.4GHz free frequency band ye yakananga kutevedzana kupararira spectrum, ine bandwidth ye83.5MHz uye yakakura data data rate ye11Mbps. Iyo nzira yekufambisa isina mutsara kupararira inosvika mazana matatu emamita kunze uye inosvika zana metres mumba pasina zvipingamupinyi, zvichiita kuti ive inonyanya kushandiswa isina waya yekufambisa protocol nhasi.
• IEEE802.11g muyero wakasanganiswa unoenderana neyakajairwa 802.11b mwero uye inopa mwero wekufambisa data we11Mbps pasekondi pa2.4GHz frequency. Inotora matekinoroji akakwidziridzwa senge mbiri chiteshi bundling, iyo inowedzera isina waya chiteshi chekufambisa bandwidth kusvika 108Mbps uye inogona kupa chaiyo TCP/IP kubuda kwe80 kusvika 90Mbps.
• IEEE802.11n inoshandisa MIMO (Multiple In Multiple Out) uye OFDM (Orthogonal Frequency Division Multiplexing) matekinoroji, ayo anogona kuwedzera huwandu hwekutapurirana kweWLAN kubva ku54Mbps inopiwa ne802.11a yazvino uye 802.11g kusvika 108Mbps, kana 60bM tops, kana 60bps kumusoro inogona kutsigira yemhando yepamusoro izwi uye vhidhiyo kutapurirana.

Shenzhen Haidiwei Optoelectronics inyanzvi inogadziraONUoptical cat midziyo uye kutaurirana kwakangwaraONUOptical katsi module. Kambani yedu parizvino inotengesa akasiyana siyana ekutaurirana ane kumusoro uye pasi zvinongedzo, senge fiber optic transceivers, Ethernet switch,OLTOptical katsi midziyo,ONUoptical katsi midziyo, zvichingodaro. Kana iwe uchida kudzidza zvakawanda nezve ruzivo rwekutaurirana tekinoroji, ndapota inzwa wakasununguka kubata kambani yedu.
