Te Rerekētanga i waenga i te Kaha o te Tohu Waea Pūkoro me te Kounga Tohu

I tēnei ao o nāianei, kua noho te tohu waea pūkoro hei wāhanga nui o tō tātou oranga o ia rā. Ahakoa te waea atu, te tuku karere kuputuhi, te tirotiro ipurangi rānei, he mea nui te hononga tohu pumau. Heoi, he maha ngā tāngata e whakapoauau ana i ngā kupu "kaha tohu" me te "kounga tohu". I roto i tēnei tuhinga, ka whakamāramahia e mātou ēnei ariā, ā, ka āwhina i a koe kia mārama ake ki ngā rerekētanga i waenga i te kaha tohu waea pūkoro me te kounga tohu.

Te Kaha o te Tohu me te Kounga o te Tohu: He aha te Rerekētanga?

Te Kaha o te Tohu

Ko te kaha o te tohu e pā ana ki te kaha o te tohu e whiwhihia ana e tō waea pūkoro mai i te teihana turanga, e inehia ana i roto i ngā desipere miliwatt (dBm). Ko te teitei ake o te uara kaha o te tohu, ko te kaha ake o te tohu; ko te iti iho o te uara, ko te ngoikore ake o te tohu. Ko ngā āhuatanga e pā nui ana ki te kaha o te tohu ko:
-Te tawhiti mai i te Teihana Tūranga: Ka tawhiti atu koe i te teihana tūranga, ka ngoikore haere te tohu.
-Ngā Ārai: Ka taea e ngā whare, ngā maunga, ngā rākau me ērā atu ārai te whakaiti i te tohu.
-Ngā Āhuatanga o te Huarere: Ka pāngia hoki te kaha o te tohu e ngā huarere kino, pērā i te ua nui, te hukarere rānei.

Kounga Tohu

Ko te kounga o te tohu e pā ana ki te māramatanga me te pumau o te tohu, e inehia ana e ngā tawhā pēnei i te Signal-to-Noise Ratio (SNR) me te Bit Error Rate (BER). Ka pā tika te kounga o te tohu ki te māramatanga o te waea me te pumau o te whakawhiti raraunga. Ko ngā āhuatanga e pā ana ki te kounga o te tohu ko:
-Te Whakararuraru: Ka taea e ngā whakararuraru mai i ngā taputapu hiko, ngā raina hiko, me ētahi atu tohu ahokore te whakaiti i te kounga o te tohu.
-Te Pūtake o te Whatunga: I ngā hāora pīki, i ngā wāhi taupori rānei, ka raru pea te kounga o te tohu i te pūtake o te whatunga.
-Pānga Maha-Ara: Ina pāngia tētahi tohu e ngā whakaata, e ngā hurihanga rānei i te wā e tuku ana, ka heke te kounga o te tohu.
Me pēhea te ine i te kaha me te kounga o te tohu waea pūkoro?

Ka taea e koe te ine i te kaha me te kounga o tō tohu waea pūkoro mā te whakamahi i tētahi taupānga e kīia nei ko "Cellular-Z," e wātea ana i te mākete taupānga Android. Mā te whakatuwhera noa i te taupānga, ka taea e koe te tirotiro i te tūnga tohu i tō rohe.
Te Kaha o te Tohu
-Uara RSRP > -80 dBm: Kaha tohu tino pai.
-Uara RSRP > -100 dBm: Kaha pai o te tohu.
-Uara RSRP < -100 dBm: Kaha tohu ngoikore.
E ai ki te pikitia i raro nei, ko te uara RSRP o te -89 e tohu ana i te kaha pai o te tohu.

Kounga Tohu
-Uara SINR > 5: Kounga tohu pai.
-Uara SINR i waenga i te 0-5: Kei te pāngia te tohu e ētahi pokanoa.
-Uara SINR < 0: Kua tino whakararuraruhia te tohu.
E ai ki te pikitia i raro nei, ko te uara SINR o te 15 e tohu ana i te kounga tohu tino pai.

Me pēhea te whakapai ake i te kaha me te kounga o te tohu waea pūkoro?

He mea nui te kaha o te tohu me te kounga o te tohu hei whakapai ake i te tohu o tō waea pūkoro. Mā te kaha o te tohu ka whakatau mēnā ka taea e koe te whiwhi tohu, ko te kounga o te tohu ka whakarite kia taea e koe te whakamahi pono i taua tohu.
Mō te hunga e hiahia ana ki te whakapai ake i te tohu waea pūkoro, ko te whakamahi i te whakakaha tohu waea pūkoro te otinga tino whānui me te pono hei whakatika i ngā take kaha me te kounga o te tohu.
