Network Signal Guru

Network signal monitoring and RF optimization has never been more accessible. Network Signal Guru is a comprehensive Android tool designed for network engineers, field technicians, and advanced users who need real-time visibility into voice and data service quality across all wireless technologies worldwide.

Gain complete insight into your mobile network performance with extensive testing capabilities for both voice and data services. Network Signal Guru measures QoS metrics that reflect genuine end-user experience, helping you identify coverage gaps, signal strength issues, and network congestion in real-time. Whether you're troubleshooting connectivity problems or conducting RF field optimization work, you'll access detailed layer-by-layer protocol analysis across GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, and 5G NR technologies.

Powerful protocol decoding and packet inspection give you visibility into 3GPP, Layer 2, Layer 3, and SIP signaling. Direct Layer 3 decoding of data protocol packets on your device enables rapid diagnosis without expensive external equipment. The integrated mapping feature combines indoor and outdoor measurements seamlessly, simplifying network assessment in complex environments like subways, shopping malls, and airports where traditional testing becomes difficult.

Band locking functionality lets you restrict your device to specific frequency bands, essential for targeted coverage validation and congestion testing. Force your phone to remain on particular bands to isolate and analyze performance on individual segments of your network infrastructure. This targeted approach accelerates optimization cycles and reduces field work duration.

Network Signal Guru supports a wide range of chipsets including Qualcomm, MediaTek Dimensity, Samsung Exynos, and Huawei Kirin processors. Depending on your device, you may need root access (Qualcomm and MediaTek), a custom ROM (Huawei Kirin), or a Samsung token (Exynos variants). Pixel 6 devices with root access can also run Exynos testing workflows.

Built by engineers for engineers, Network Signal Guru delivers professional-grade network diagnostics at a fraction of traditional test tool costs. Carriers and network operators worldwide rely on this app to streamline maintenance, reduce optimization expenses, and accelerate troubleshooting. Stop paying thousands for dedicated testing equipment—Network Signal Guru brings lab-quality analysis to your Android device and your fingertips.
