Maximum Cell Radius for the Forward Link: 1057896

1. Maximum Cell Radius for the forward link

L = A+ B log₁₀ f-13.82 log₁₀ (h_b) – C +[44.9-6.55 log₁₀ (h base)] log d

Parameters for a large city

A = 46.30

B = 33.90

C =

H => height of antenna = 60m

F = 2600MHz

Solution

Log₁₀ d =

Log₁₀ d =

Log₁₀ d = -1. 3960

D = log^-1 -1.3960 = 0.0402 km

Zero fade margin =  Prx – Prxt

FM = -110 dBm- 0 dB

=-110 dBm

•  Reverse link and zero fade margin

L = A+ B log₁₀ f-13.82 log₁₀ (h_b) – C +[44.9-6.55 log₁₀ (h base)] log d

Parameters for a large city

A = 46.30

B = 33.90

C =

H => height of antenna = 1.5m

F = 2600MHz

Solution

Log₁₀ d =

Log₁₀ d =

Log₁₀ d = -1. 360

D = log^-1 -1.3036 = 0.0437 km

Zero fade margin = Prx – Prxt

FM = -114 dBm – 0dB

= – 114 dBm

• The forward link is 0.0402 km while the reverse link is 0.0437 km. Therefore, the link is balanced.
• The difference between the receiver power and receiver sensitivity is determined by the fade margin.
• (a)=>47.4m, (b)=>90m
