Kutheni le nto umsebenzi weselfowuni xa umqondiso ugcwele imivalo?

Isizathu 1: Ixabiso lefowuni alichanekanga, akukho signali kodwa sibonisa igridi epheleleyo?

1. Kwinkqubo yokufumana nokuthumela imiqondiso, ifowuni ephathekayo ine-Chip ye-Baseband ukuya e-Pip ekusebenzeni kwaye ikhuphe umqondiso. Ukuba ukusebenza kakuhle kwe-chip akulunganga, uphawu lwefowuni luya kuba buthathaka.

I-2. Ifowuni nganye yefowuni ayinayo imigaqo efanayo kumgangatho wegridi yomqondiso, kwaye ezinye ii-rands ziya kunciphisa ixabiso ukuze libonakale "umqondiso ulungile", ke umqondiso womboniso wefowuni ugcwele, kodwa isiphumo esisebenzayo sihlwempuzekile.

Isizathu 2: Impembelelo yokusiNgqongileyo yeSitayile esiyingqongileyo, ezikhokelela "kwiPhephailies" ezingaboniyo ".

Amaza e-Electromagnetic amaza avelisa kwicala elilawulwa yi-eriyali, kunye nezithintelo ezithintela ukusasazwa kwamaza e-electromagnetic, iiglasi zentsimbi ezinokufakwa kwifowuni yefowuni. Ukuba kwindawo engaphantsi okanye inyusi, le ndawo ayiyonto inkulu okanye emphethweni womqobo, i-elektromagnetic wavutha umqobo kunzima ukungena okanye ifowuni ayinakubakho nto.

Umgangatho wokulinganisa amandla efowuni yefowuni ibizwa ngokuba yiRRRP (ireferensi yomqondiso ofumana amandla). Iyunithi yomqondiso yi-DBM, uluhlu lwe-it-50dbm ukuya -130dBm, kunye neyona nto incinci yexabiso, yomelela umqondiso.

Kuxhomekeka kwimodeli yefowuni kunye nomphathi, kunokubakho umahluko osebenzayo. Ezi ndlela zilapha ngasentla zilungiselelwe kuphela.
