XULOSA


Bazaviy stansiya antennasini oʻrnatishda chastota diapazoni, qamrov maydoni, daromad kabi omillarni hisobga olish kerak. Bundan tashqari bazaviy stansiyalarini bir-biridan qancha masofada oʻrnatish, ularga yetgan zararni aniqlash va bu zararni tezlik bilan bartaraf etish, bazaviy stansiyalarda tarqalayotgan signalni uzoqqa yetkazish antennalarining optimal ishlashi va ishonchli aloqani taʻminlashda muhim ahamiyatga ega. Telekommunikatsiya tizimida foydalanuvchilar soni kundan kunga koʻpayib bormoqda. Foydalanuvchilar sonining koʻpayishi bilan ularning mobil qurilmalarida bajarayotgan turli xildagi operatsiyalari hududlardagi bazaviy stansiyalarning ishlashini sekinlashtiradi. Bu esa Respublika iqtisodiyotini oʻsishiga salbiy taʻsir koʻrsatadi. Biz bazaviy stansiyalarini shunday oʻrnatishimiz kerak-ki, bazaviy stansiyadan tarqalayotgan signal foydalanuvchiga tez va samarali yetib borishi va shu bilan bir qatorda bazaviy stansiyalardagi xarajatlarni kamaytirishga erishish kerak. Bu magistrlik dissertatsiya ishida Farg‘ona viloyati hududi uchun ishlab chiqqan model asosida bazaviy stansiya xarajatlarini minimallashtirish masalasi bazaviy stansiyalarning sonini kamaytirish yoʻli bilan hal qilindi. Bazaviy stansiyalari sonining kamayishi orqali signal uzoq masofaga tarqalish masalasi ham hal qilindi.
