GoodPAW: RF Signal & Band Lock

About GoodPAW: RF Signal & Band Lock

GoodPAW — RF measurement for engineers, without the license conversation.

Lock to any band. Lock to any channel. Collect LTE and 5G. All free.

On professional test platforms, band lock and channel lock are licensed features — and collecting LTE is commonly a separate license from collecting 5G. In GoodPAW those are the free tier, and they stay free for everyone through August 2027.

FREE — THROUGH AUGUST 2027

• Band lock — force the handset onto any supported band
• Channel lock — hold a specific channel
• LTE collection — RSRP, RSRQ, SINR, CQI, PCI, EARFCN, eNB ID, TAC
• 5G NR collection — SS-RSRP, SS-RSRQ, SS-SINR, NR-ARFCN
• Live dashboard with carrier aggregation status
• dBm to Watts converter
• Theoretical RSRP calculators (LTE, 5G FR1, 5G FR2) built on 3GPP formulas

PAID — AND WE SAY SO UP FRONT

• RF spot checks and floor plan mapping
• Network database — frequencies, bands and operators by region
• Project logging and data export
• Continuous walk tests and live reporting

We would rather you see the paywall now than discover it after installing.

WHY BAND LOCK MATTERS

A handset selects whichever band it prefers. Good for the user, useless for measurement — you cannot characterize n71 coverage while the phone keeps reselecting to b66. Lock the band and every reading comes from the band you are actually assessing. That turns an argument into a measurement.

WHO THIS IS FOR

• RF engineers running quick site checks between full drive tests
• DAS and in-building wireless technicians
• Team leads who want the whole crew measuring, not just the one person holding a seat license
• Anyone curious which band their phone is really on, and what happens when you change it

WHAT THIS IS NOT

GoodPAW reads what your device modem reports. It is not scanner-grade, and it is not a replacement for TEMS, Nemo or XCAL on a full drive test campaign. It is the tool already in your pocket. Different job.

5G metrics require Android 11 or later and a 5G-capable device. Available on Android; iOS is on the roadmap.

THE FREE YEAR

We are a small team and we need this used on real sites by people who will tell us where it breaks. That is worth more to us right now than subscription revenue.

So the measurement tools are free for everyone until August 2027. When terms change, everyone who joined during the free year keeps founder pricing — and users who send us feedback get more.
