HiCellTek provides practical 4G and 5G network diagnostics for supported Android devices. Engineers can inspect RF metrics such as RSRP, RSRQ and SINR, decode LTE and NR Layer 3 signaling, assess VoLTE voice quality, and export diagnostic logs for further analysis. It is built for field testing, troubleshooting and RF optimization workflows. Available capabilities depend on the supported device, software version and configuration.

Hi Product Hunt, A RAN engineer asked if I had an Excel macro to visualize interference per PRB. I decided to build a reusable browser tool instead. It imports CSV or XLSX, supports wide and long counter layouts, handles multiple cells, and fits the complete PRB range on screen. For dBm, the mean is calculated in linear power before converting back. Raw counters use the arithmetic mean. I made it free and open source because this kind of first analysis should be easy to access. The imported file and its metadata stay in the browser. I would really like feedback from RAN engineers using different OSS export structures. Live tool: https://hicelltek.com/tools/nr-p... Source: https://github.com/tsebai/nr-prb...
