Produktbeschreibung

Sotowaq swqz' stala ochen' wazhnoj w nashi dni. Jeto stanowitsq ochewidnym, kogda ära smartfonow powsemestno ispol'zuetsq lüd'mi. Odnako, nezawisimo ot togo, naskol'ko horoshi smartfony, oni wse rawno zawisqt ot togo, naskol'ko äffektiwno postawschiki uslug mogut obespechit' signal pokrytiq. Chastota millimetrowyh woln opredelqetsq ot 3 GGc do 300 GGc, a dlina wolny - ot 1 mm do 100 mm. Iz-za korotkoj dliny wolny nekotorye parametry dolzhny byt' opredeleny dlq razlichnyh sred. Poteri puti qwlqütsq znachitel'nym faktorom, kotoryj opredelqet razmer qchejki, a takzhe rasstoqnie dosqgaemosti. Millimetrowye wolny imeüt wysokie poteri puti po srawneniü s bolee nizkimi chastotami, kotorye imeüt bol'shuü dlinu wolny. Na ätu harakteristiku ochen' wazhno obratit' wnimanie, poskol'ku w uslowiqh mobil'nosti melkomasshtabnye zamiraniq i krupnomasshtabnye zamiraniq okazywaüt ochen' sil'noe wliqnie na proizwoditel'nost' uslug 5G. V knige rassmatriwaütsq razlichnye temy izmerenij w pomescheniqh i na otkrytom wozduhe dlq opredeleniq modelej poter' trafika, kotorymi qwlqütsq modeli Closed-In Reference i Alpha-Beta-Gamma Models. Metodologiq sostoit iz äxperimenta i modelirowaniq w Matlab. Nakonec, polucheny i proanalizirowany rezul'taty modelej poter' w trakte.
