5G NR Throughput Calculator

The 5G New Radio (NR) throughput calculation involves several parameters that determine the maximum achievable data rate in a 5G network. These parameters include bandwidth, MIMO (Multiple Input Multiple Output) layers, modulation order, scaling factor, coding rate, and the number of resource blocks. This calculator simplifies the process of estimating the throughput of a 5G NR connection based on these inputs.

Historical Background

5G NR, the global standard for a unified, more capable 5G wireless air interface, was developed to meet the vast diversity of connectivity needs of the next decade. The 5G NR throughput calculation reflects the network's ability to transmit a high volume of data efficiently, crucial for supporting the network's high data rate requirements.

Calculation Formula

The throughput formula incorporates multiple factors, including the configuration of the network's physical layer:

\[ \text{Throughput (Mbps)} = \frac{\text{Bandwidth (MHz)} \times \text{MIMO Layers} \times \log_2(\text{Modulation Order}) \times \text{Scaling Factor} \times \left(\frac{\text{Coding Rate}}{1024/948}\right) \times \text{Resource Blocks} \times 12 \times 14 \times 10 \times \frac{1000}{10} \times (1 - 0.14)}{1e6} \]

Example Calculation

For a network configuration with 100 MHz bandwidth, 4 MIMO layers, 256QAM modulation, a scaling factor of 1, a coding rate of 0.948, and 273 resource blocks, the throughput is

:

\[ \text{Throughput} = \frac{100 \times 4 \times \log_2(256) \times 1 \times (0.948 / (1024 / 948)) \times 273 \times 12 \times 14 \times 10 \times \frac{1000}{10} \times (1 - 0.14)}{1e6} \approx 2,337 \text{ Mbps} \]

Importance and Usage Scenarios

Understanding and calculating 5G NR throughput is essential for network planning and optimization. It helps in assessing the network's performance capabilities and ensuring that the infrastructure can meet the data demands of various applications, from mobile broadband to massive IoT connectivity.
