ʻO ka mea mua, e nānā kākou i ke kiʻikuhi hoʻolālā maʻamau o nā kaʻapuni WiFi RF: (Ua māhele ʻia ka kiʻi hoʻolālā WiFi i kēia mau modula, me ka ʻāpana polū o RTL8192FR i hoʻohui ʻia i ka MCU)
ʻO ka hana hōʻailona ʻokoʻa: ʻO ka mea maʻamau, ua hana ʻia nā hōʻailona WiFi RF me ka hoʻohana ʻana i ka hoʻoili hōʻailona ʻokoʻa e hoʻonui ai i ka hiki ke kūʻē.I nā huaʻōlelo ʻē aʻe, e hoʻouna ka transceiver i ka hōʻailona ma ke ʻano ʻokoʻa, a pono hoʻi e hāʻawi ke kaapuni waho i ka hoʻokomo no ka hōʻailona RF ʻokoʻa i ka transceiver.
ʻElua mau ala like ʻole e mālama ai ma aneʻi:
1. Ma ka hoʻohana ʻana i ka mea kaulike, ua hoʻohui ʻia ka hōʻailona ʻokoʻa me kahi ʻokoʻa ʻāpana o 180 ° i hoʻokahi hōʻailona RF hoʻopau ma hope o ka hele ʻana i ka mea kaulike.
2. Nā ʻāpana ʻokoʻa
He aha ka hōʻailona ʻokoʻa i loaʻa i ka transceiver?ʻO ka hōʻailona i loaʻa i ka transceiver mai ka haʻahaʻa haʻahaʻa haʻahaʻa i ka mua-hope.E like me ka mana amplifier, ka haʻahaʻa haʻahaʻa amplifier hana pū kekahi i hoʻokahi hopena RF hōʻailona.No laila, pono mākou e hoʻololi i ka hoʻopuka hōʻailona e ka leo haʻahaʻa haʻahaʻa.ʻO ka hōʻailona i loaʻa a me ka hōʻailona i hoʻouna ʻia o ka transceiver he aneane hoʻololi i nā kaʻina hana o kekahi, no laila ua like ke ʻano o ke kaʻapuni me ka ʻē aʻe.
ʻO ka mea i luna nei kahi ʻike pōkole o ka WIFI Design Summary - Barron, hiki ke hoʻohana ʻia i mea kuhikuhi no kēlā me kēia.Loaʻa i kā mākou hui kahi hui ʻenehana ikaika a hiki ke hāʻawi i nā lawelawe ʻenehana loea i nā mea kūʻai aku.I kēia manawa, loaʻa i kā mākou hui nā huahana like ʻole: naʻauaoonu, module optical communication, module fiber optical, sfp optical module, olt equipment, Ethernet switch and other network tools.Inā makemake ʻoe, hiki iā ʻoe ke aʻo hou e pili ana iā lākou.
