RSSI Calculator

Estimate received signal level for your PtP link.

Link parameters

Same formula as the original NetPoint site: FSPL = 20·log₁₀(km) + 20·log₁₀(GHz) + 92.45 · RSSI = EIRP + Grx − Lrx − FSPL

Site A · Transmitter
Site B · Receiver

RSSI interpretation guide

Scale published in the original NetPoint calculator.

−44 to 0 dBm

Danger

You may damage the radio — reduce TX power

−45 to −55 dBm

Excellent

Perfect, stable signal

−56 to −64 dBm

Good

Reliable — still room to improve

−65 to −70 dBm

Low

On the edge — keep aligning

−71 to −80 dBm

Very low

Weak signal — improve urgently

−81 to −100 dBm

Minimum / critical

Barely connected — redesign

Pro tip: a solid link should stay between −45 and −64 dBm.

How to use it

  1. Enter TX power, antenna gains (site A and B), and jumper/connector losses.
  2. Set distance in km and frequency in GHz (e.g. 5.8, 6.2, 11).
  3. Press Calculate to see FSPL, link budget, and estimated RSSI.
  4. Use Load example (20 dBm · 24 dBi · 10 km · 5.8 GHz) to validate the flow.

Real RSSI also depends on Fresnel, alignment, noise, and interference. To size a new NetPoint link, reach us on WhatsApp or review beamwidth.
