Pocket testers are convenient. They’re also wrong.
If your test setup doesn’t match the final installation, your results are guesswork. CellTester uses the actual router, the actual antennas and the actual SIM - so you know exactly what will work before you commission. Works across EE, Vodafone, Three and O2. 4G, 5G, NB-IoT, 5G RedCap and full MIMO analysis.
Most signal testers were designed for voice and basic data. IoT and M2M deployments have moved far beyond that. The tools haven’t.
Handheld testers use an internal stub antenna and their own generic modem. A Teltonika with an external LPDA at rooftop height can show 15-20 dB more signal than a handheld held at standing height. Different antenna. Different gain. Different result. That’s not a test. It’s a guess.
NB-IoT, LTE-M, 5G NR and 5G RedCap are live in UK networks right now. EE, Vodafone, Three and O2 are all deploying them. Most testing tools top out at basic 4G LTE. If you cannot test the technology your device will use, you cannot commission it properly.
Modern IoT routers use 2x2 and 4x4 MIMO. A faulty antenna port, a bad connector or a mismatched cable can halve throughput while signal metrics look perfectly fine. Standard testers don’t read per-port RSRP. CellTester does.
Most engineers pick the first network that registers and move on. An automated multi-operator sweep across all four UK networks with speed tests takes three minutes and finds the best primary and failover operator automatically.
No documented signal levels. No evidence the installation was done properly. When a connection fails six months later there is no baseline to compare against. No PDF certificate. No data. Just a memory of it seemed fine at the time.
Routers shipped with default credentials and open management ports are being deployed onto public IP SIMs every day across the UK. A signal tester that doesn’t check the security posture of the device it just commissioned is leaving the job half done.
CellTester connects to the Teltonika router you are actually deploying - with the antennas you are actually fitting - and reads signal directly from the installed hardware. Real data. Real conditions. Certainty before you commission.
Connect to the router via WiFi or Ethernet. Credentials are AES-256 encrypted in your browser. Nothing is transmitted to CellTester servers.
CellTester locks to each UK operator in turn - EE, Vodafone, Three, O2 - captures RSRP, RSRQ, SINR and runs a speed test on each. Fully automated. 2-4 minutes.
RSRP updates every 0.6 seconds. Rotate the antenna, watch signal peak on a scrolling graph. Lock off at the optimal bearing. No guesswork.
Primary operator, failover network, band lock, APN and ping watchdog settings - all recommended and applied to the router via the RutOS API in one tap.
Router WAN IP scanned for exposed ports and known CVEs. Critical findings flagged before the customer goes live. One less thing that will come back to you.
Download a professional commissioning certificate with all signal data, MIMO analysis, config applied and security status. Stored in your account. Unlimited history.
Sites often don’t have power yet. Or you’re surveying before the install phase. With a Teltonika BAT120 or a suitable 12V DC power bank, CellTester runs entirely from battery. Turn up, power the router, attach the antennas, run a full sweep. No extension leads. No waiting for the electrician. The entire commissioning kit fits in a bag.
Same modem your customer gets. Same performance you’ll see in production.
Teltonika BAT120 integrates cleanly. A quality 12V DC power bank works too.
Test with the actual antennas going on the wall. Real gain. Real MIMO analysis.
Multi-network SIM tests all four UK operators automatically. Best network wins.
CellTester connects to Teltonika routers running RutOS 07.04 and above via the RutOS API. No drivers. No software install. Browser-based on any phone or laptop.
