Cellfire for Android
The most capable cellular RF scanner you can hold in your hand. Real-time multi-carrier scanning, GPS drive testing, deep cell analysis — all from your pocket.
Your carrier has been hiding
what your phone actually knows.
Every Android device has a full RF modem reporting dozens of real-time metrics. Bars are a marketing decision. Cellfire bypasses all of it and reads the raw data directly.
Most apps never touch your modem. They report one of two things:
- Your registered carrier's signal — the number your carrier chooses to surface, optimized to look good
- Crowdsourced data — what other users near your GPS location have reported, averaged and smoothed
Neither is your phone's actual RF state. Neither shows what your modem sees right now.
Cellfire reads the modem directly. No middleman. No averages. No carrier filter.
- Shows you "bars" — a number your carrier controls, not your modem
- Only reports your serving cell — the tower the carrier picked for you
- Uploads your location and signal scans to their servers
- Sells your RF data to carriers and analytics companies
- Gives you 1 metric when your modem is producing 20+
- Requires root, a carrier deal, or expensive hardware to go deeper
- Direct modem access: RSRP, RSRQ, SINR, CQI, ARFCN, PCI, TAC, timing advance — all of it, live
- Full neighbor cell list — every tower your phone hears, not just the one it's attached to
- Nothing leaves your device. No uploads, no accounts required to collect data
- Your data is yours — export CSV, open in RF Studio, or share with your team
- Per-cell full panel: band, frequency, power, quality, and cell identity in one view
- Works on any unlocked Android — no root, no carrier permission, no expensive hardware
The tool serious RF people
actually reach for.
From DAS installs to carrier disputes — Cellfire gives you the ground truth that coverage maps and speed tests can't.
Walk a building floor by floor and collect GPS-stamped RSRP, SINR, and serving cell data at every waypoint — all carriers at once. Pre-install surveys that produce real data. Post-install verification that holds up in a report.
- Map signal penetration by floor, room, and carrier before a single piece of cable goes in
- See RSRP and SINR side-by-side — not just which bar you're at
- Post-install: compare before/after measurements with exportable, GPS-tagged data
- Feed measurements into RF Studio to compare against your propagation model
Start a session, drive your route, done. GPS-tagged signal data every second — no laptop, no external hardware, no setup ritual. Your phone does the work of a $15K drive test rig.
- Continuous RSRP, RSRQ, SINR, and band logging along your entire route
- PCI and ARFCN tracking to catch tower handoffs and coverage gaps in real time
- Export clean CSV that feeds directly into your existing analysis tools
- Cover more ground with less gear — your Android is your rig
You're paying for enterprise wireless and your team is dropping calls in the warehouse. Cellfire walks your facility and produces a GPS-mapped dataset that tells you exactly where coverage fails — so you bring evidence to the carrier conversation, not complaints.
- Walk every floor, wing, and loading dock — map actual RSRP levels, not carrier claims
- Identify whether dead zones are carrier-specific or affect everyone
- Build a coverage baseline to hold carriers accountable to their SLA commitments
- Show up to the meeting with GPS-tagged measurement data — not anecdotes
Parked at a new campsite, debating which SIM to run? Cellfire shows every carrier's actual RSRP at your exact location — not marketing maps. Know whether you're on a strong LTE band or crawling off a distant tower before you commit.
- See all carriers' RSRP simultaneously at your current location
- Check what band and frequency you're on — B12, B71, n41, or NR SA
- Identify the nearest tower PCIs to understand your actual options
- Make informed carrier vs. Starlink decisions with real RF data, not guesses
Does your rooftop antenna build actually do anything? Cellfire shows RSRP live as you adjust orientation and height. Build, measure, iterate — with real numbers instead of speed test variance.
- Watch RSRP change live as you rotate, tilt, or reposition an external antenna
- Test RF shielding effectiveness with before/after measurements
- Map signal leakage in your workspace to hunt down interference sources
- Compare antenna builds objectively — logged RSRP per position, exported to CSV
