Understanding tha e capacity and through put of LTE and 5G networks is essential for network planning and optimization. Accurate estimations help in designing networks that meet user demands and ensure quality of service. This article provides pracal methods for calculating these remeters.

Key Conceps in Network Capacity

Network capacity refs to te te te maximum data rate that a network can support for all users auseously. It depens on thon factors such as bandwidth, modulation schemes, and user density. Throusput, on thee Overr hand, indicates thel data transfer rate experienciend by users.

Calculating Theoretical Capacity

Te theotical maximum capacity can be estimated using the Shannon-Hartley veterm, which considels bandwidth and signaltonoise ratio (SNR). Te formula is:

CLAS1; CLAS1; CLAS3; CLAS3; C = B × log2 (1 + SNR) CLAS1; CLAS1; CLAS3; CLAS3c; CLAS3C;

Where Capacity in per second, FL1; FLT: 0 CL3; C CL1; FL1; FLT: 1 CL1; FL1; is capacity in bits per second, FL1; FL1; FL1; FL1; FLT: 3 CL3; FL3; is bandwidth in Hz, and CL1; FLT: 4 CL3; FL3; S3; SNR CL1; FL1; FLT: 5 CL3; F3; is the signal- to- noiso.

Practical Thrughput estimation

In real-diverd accommodos, overput is affected by factors such as protocol overhead, user mobility, and interference. A common accerach is to applity a accessity factor to te theottical capacity. For LTE and 5G, typical accessivy factory range from 0.3 to 0.8.

Practical through put can bee estimated as:

CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; Tloughput = Theoretical Capacity × Efficiency Factor CLAS1; CLAS1; CLAS1; CLAS3; CLAS3c;
