Wendelin Telecom: Calculate and Visualize the New KPI: UL Noise Indicator

UL Noise Indicator

• UL_Noise_Indicator = RX_RMS − 10·log10(BW_Hz)
• In the 3GPP LTE standard, the mapping between channel bandwidth BW_Hz and the number of resource blocks n_rb_ul is defined as follows:
  1.4 MHz = 6 RBs, 3 MHz = 15 RBs, 5 MHz = 25 RBs, 10 MHz = 50 RBs, 15 MHz = 75 RBs, 20 MHz = 100 RBs
• UL Noise Indicator is a uplink quality metric that quantifies interference relative to overall uplink activity.

Changes Included

• Extend KPI computation logic to include UL Noise Indicator.
• Add unit tests to validate the new KPI.
• Add web UI test suite to cover new KPI displays.
