2.4GWiFi Protocol Standard

2.4GWiFi na-arụ ọrụ na bandwit 2.4GHz, yana ọnụọgụ ugboro nke 2400-2483.5MHz. Isi ọkọlọtọ sochiri bụ ọkọlọtọ IEEE802.11b/g/n nke Institute of Electrical and Electronics Engineers (IEEE) mepụtara. N'okpuru ebe a, anyị ga-enye nkọwa zuru ezu maka ụkpụrụ ndị a:

• IEEE802.11 bụ ọkọlọtọ netwọk mpaghara mpaghara ikuku nke IEEE mepụtara na mbụ, nke a na-ejikarị eme ihe iji dozie ohere ikuku maka ndị ọrụ na ọnụ ahịa n'ọfịs na netwọk ụlọ akwụkwọ. Azụmahịa ahụ nwere oke na ịnweta data, yana oke ọsọ nwere ike iru naanị 2Mb/s. N'ihi enweghị ike nke IEEE 802.11 iji gboo mkpa ndị mmadụ n'ihe gbasara ọsọ na ebe nnyefe, teknụzụ a bụ ihe ochie.

• Ọkọlọtọ IEEE802.11b, nke a makwaara dị ka teknụzụ ikwesị ntụkwasị obi ikuku, na-eji bandwit 2.4GHz na-akwụghị ụgwọ nke mba ụwa amatara maka ụdị mgbasa ozi n'usoro n'usoro, yana bandwit nke 83.5MHz yana ọnụego nnyefe data kachasị nke 11Mbps. Usoro mgbasa ozi na-enweghị mgbasa ozi kwụ ọtọ ruru mita 300 n'èzí yana ruo 100 mita n'ime ụlọ na-enweghị ihe mgbochi, na-eme ka ọ bụrụ usoro mgbasa ozi ikuku na-ejikarị eme ihe taa.

• IEEE802.11g bụ ọkọlọtọ ngwakọ na-adaba na ọkọlọtọ 802.11b ọdịnala ma na-enye ọnụego mbufe data nke 11Mbps kwa sekọnd na ugboro 2.4GHz. Ọ na-anakwere teknụzụ emelitere dị ka njikọta ọwa abụọ, nke na-abawanye bandwidth nnyefe ọwa ikuku ruo 108Mbps ma nwee ike inye ezigbo ntinye TCP/IP nke 80 ruo 90Mbps.

• IEEE802.11n na-anabata teknụzụ MIMO (Multiple In Multiple Out) na OFDM (Orthogonal Frequency Division Multiplexing), nke nwere ike ịbawanye ọnụego nnyefe nke WLAN site na 54Mbps nke 802.11a na 802.11g dị ugbu a ruo 108Mbps, ma ọ bụ ọbụna ruo 600Mbps. nwere ike ịkwado nnyefe olu na vidiyo dị elu.
