BS abonentlariga xizmat ko‘rsatish uchun chastota kanallarini hisoblash.
Bitta
sektordagi abonentlarga xizmat ko‘rsatish uchun foydalaniladigan chastotali kanallar soni
quyidagi formula bilan aniqlanadi:
𝑛
𝑠
= 𝑖𝑛𝑡 (
𝑁
𝐾
𝑐∙𝑁
𝑆
)
(2)
𝑛
𝑠
= 𝑖𝑛𝑡 (

4∙3
) = 10
bu yerda N
S
- sektorlar soni
Bitta BS xizmat ko‘rsatadigan abonentlar sonini hisoblash.
Eng katta yuklangan soatda
bitta abonentning ma’lum faolligi bilan bitta BS xizmat ko‘rsatadigan abonentlar sonini quyidagi
formula yordamida hisoblash mumkin:
𝑁

) ∙ 3 = 828
Bitta BS xizmat ko‘rsatadigan abonentlar soni 828 tani tashkil qiladi.
BS xizmat ko‘rsatish zonasining radiusini hisoblash.
Radius qiymatini quyidagi ifoda
yordamida aniqlash mumkin:
