ʻOkoʻa ma waena o ka ikaika o ka hōʻailona kelepona a me ka maikaʻi o ka hōʻailona

I kēia ao, ua lilo ka hōʻailona kelepona i mea nui loa o ko kākou ola o kēlā me kēia lā. Inā paha e kelepona ana, e hoʻouna ana i nā leka uila, a i ʻole e kele pūnaewele ana, he mea nui ka pilina hōʻailona paʻa. Eia nō naʻe, nui ka poʻe e huikau i nā huaʻōlelo "ikaika hōʻailona" a me "maikaʻi hōʻailona." Ma kēia ʻatikala, e wehewehe mākou i kēia mau manaʻo a kōkua iā ʻoe e hoʻomaopopo maikaʻi i nā ʻokoʻa ma waena o ka ikaika hōʻailona kelepona a me ka maikaʻi hōʻailona.

Ka Ikaika Hōʻailona vs. Ka Maikaʻi o ka Hōʻailona: He aha ka ʻokoʻa?

Ikaika Hōʻailona

ʻO ka ikaika hōʻailona e pili ana i ka mana o ka hōʻailona i loaʻa i kāu kelepona paʻalima mai ke kahua kikowaena, i ana pinepine ʻia ma nā decibels milliwatts (dBm). ʻO ke kiʻekiʻe o ka waiwai ikaika hōʻailona, ​​ʻoi aku ka ikaika o ka hōʻailona; ʻo ka haʻahaʻa o ka waiwai, ʻoi aku ka nāwaliwali o ka hōʻailona. ʻO nā mea nui e hoʻopilikia i ka ikaika hōʻailona:
-Ka mamao mai ke kahua kahua: ʻO ka mamao aku ʻoe mai ke kahua kahua, ʻoi aku ka nāwaliwali o ka hōʻailona.
-Nā mea keakea: Hiki i nā hale, nā mauna, nā lāʻau, a me nā mea keakea ʻē aʻe ke hoʻonāwaliwali i ka hōʻailona.
-Nā Kūlana o ke Aniau: Hiki i ke aniau ʻino, e like me ka ua nui a i ʻole ka hau, ke hoʻopilikia i ka ikaika o nā hōʻailona.

Ka maikaʻi o ka hōʻailona

ʻO ke ʻano o ka hōʻailona e pili ana i ka moakāka a me ke kūpaʻa o ka hōʻailona, ​​​​i ana pinepine ʻia e nā palena e like me ka Signal-to-Noise Ratio (SNR) a me ka Bit Error Rate (BER). Hoʻopilikia pololei ka maikaʻi o ka hōʻailona i ka moakāka o ke kelepona a me ke kūpaʻa o ka hoʻoili ʻikepili. ʻO nā mea e hoʻopilikia ai i ka maikaʻi o ka hōʻailona:
-Ke komo ʻana: ʻO ke komo ʻana mai nā mea uila, nā laina mana, a me nā hōʻailona uea ʻole ʻē aʻe hiki ke hoʻemi i ka maikaʻi o ka hōʻailona.
-Paʻa Pūnaewele: I nā hola kiʻekiʻe a i ʻole ma nā wahi i noho nui ʻia, hiki i ka paʻa pūnaewele ke alakaʻi i ka maikaʻi ʻole o ka hōʻailona.
-Hopena Multipath: Ke hālāwai kahi hōʻailona me nā reflections a i ʻole refractions i ka wā o ka hoʻoili ʻana, hiki iā ia ke hopena i ka hōʻino ʻana o ka maikaʻi o ka hōʻailona.
Pehea e ana ai i ka ikaika a me ka maikaʻi o ka hōʻailona kelepona?

Hiki iā ʻoe ke ana i ka ikaika a me ka maikaʻi o kāu hōʻailona kelepona me ka hoʻohana ʻana i kahi polokalamu i kapa ʻia ʻo "Cellular-Z," i loaʻa ma ka mākeke polokalamu Android. Ma ka wehe wale ʻana i ka polokalamu, hiki iā ʻoe ke nānā i ke kūlana hōʻailona ma kou wahi.
Ikaika Hōʻailona
-Ka Waiwai RSRP > -80 dBm: Ikaika hōʻailona maikaʻi loa.
-Ka Waiwai RSRP > -100 dBm: Ikaika hōʻailona maikaʻi.
-Ka Waiwai RSRP < -100 dBm: Ikaika hōʻailona maikaʻi ʻole.
E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, ʻo ka waiwai RSRP o -89 e hōʻike ana i ka ikaika hōʻailona maikaʻi.

Ka maikaʻi o ka hōʻailona
-Ka Waiwai SINR > 5: Maikaʻi ka maikaʻi o ka hōʻailona.
-Ka waiwai SINR ma waena o 0-5: Ke ʻike nei ka hōʻailona i kekahi mau mea hoʻopilikia.
-Ka Waiwai SINR < 0: Ua hoʻopilikia nui ʻia ka hōʻailona.
E like me ka mea i hōʻike ʻia ma ke kiʻi ma lalo nei, ʻo ka waiwai SINR o 15 e hōʻike ana i ka maikaʻi o ka hōʻailona.

Pehea e hoʻomaikaʻi ai i ka ikaika a me ka maikaʻi o ka hōʻailona kelepona?

He mea nui ka ikaika o ka hōʻailona a me ka maikaʻi o ka hōʻailona no ka hoʻomaikaʻi ʻana i kāu hōʻailona kelepona. Hoʻoholo ka ikaika o ka hōʻailona inā hiki iā ʻoe ke loaʻa i kahi hōʻailona, ​​​​ʻoiai ʻo ka maikaʻi o ka hōʻailona e hōʻoiaʻiʻo hiki iā ʻoe ke hoʻohana pono i kēlā hōʻailona.
No ka poʻe e ʻimi nei e hoʻomaikaʻi i kā lākou hōʻailona kelepona, ʻo ka hoʻohana ʻana i ka mea hoʻonui hōʻailona kelepona ka hopena piha loa a hilinaʻi hoʻi e hoʻoponopono ai i ka ikaika hōʻailona a me nā pilikia maikaʻi.
ʻO Lintratek, me ka ʻoi aku o 13 mau makahiki o ka ʻike ma kamea hoʻonui hōʻailona keleponaʻoihana, hāʻawi i kahi laulā piha o nā huahana, mai nā mea hoʻoikaika hōʻailona home mana haʻahaʻa a hiki i ka pae kalepanā mea hana hou o ka fiber opticInā ʻoe e ʻimi nei i nā hoʻonā no nā wahi noho, ʻoihana, a ʻoihana paha, hāʻawi ʻo Lintratek i nā hoʻonā uhi hōʻailona kelepona maikaʻi loa.
