Key Concepts in Network Capacity
Network capacity refers to thee maximum data rate that a network can support for all users consideraneously. It depends on factors such as bandwidth, modulation schemes, and user density. Throughput, on the tell text tell actual data transfer rate experimented d buy users.
Kalkulating Teoretyka Capacity
Thee theretical maximum capacity can be estimated using thee Shannon-Hartley thereim, which considers bandwidth andd signal- to- noise ratio (SNR). The formula i:
(1 + SNR) 1; (1 + SNR)
Where Sig1; Xi1; FLT: 0 Sig3; C Sig1; Xig1; FLT: 1 Sig3; Xig3; is capacity in bits per second, Xig1; FLT: 2 Signatu3; B Signatu1; Xig1; FLT: 3 Signe3; Xig3; is bandwidth in Hz, and Signatu1; FLT: 4 Signe3; X3SN Q1; FLT: 5 Signal3; X3; is the signal- to- noise ratio.
Praktykal Throughput Estimation
I n real- exterd controls, through put is affected by factors such as protocol overhead, user mobility, ande interference. A contron approach is to applicy a efficiency factor to these thereticala capacity. For LTE and 5G, typical efficiency factors range from 0.3 to.8.
Praktykal through put can be estimated as:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Throumpt = Theoretical Capacity × Efficiency Factor Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
Sample Calculation
Suppose an LTE network has a bandwidth of 20 MHz and an SNR of 20 dB. Converting SNR to linear scale:
(20 / 10) = 100 (11); FLT: 1 (3x); FLT: 1 (3x);
Teoretyczna pojemność:
