Cellular-Pro

Cellular-Pro is a professional-grade network diagnostic tool for Android. It provides advanced users, network engineers, and enthusiasts with deep insights into their mobile connection. The app goes far beyond basic signal strength indicators, offering a suite of technical features for real-time analysis and optimization of cellular networks, including 5G NR and LTE. Users who require granular control over their device's modem or need to perform detailed field testing will find Cellular-Pro to be an indispensable utility. This powerful application turns a compatible Android smartphone into a sophisticated network monitoring device.

Real-Time Wireless Measurement Parameter Display

Upon launching Cellular-Pro, users are greeted with a comprehensive dashboard of live network data. The interface displays critical wireless measurement parameters for all major network types, including NR 5G, LTE, GSM, and WCDMA. Users can monitor metrics like RSRP, RSRQ, SINR, and cell bandwidth in real time, which is essential for diagnosing connection quality and identifying weak signal areas. This constant stream of data allows for precise benchmarking of network performance. The depth of information provided by Cellular-Pro makes it a vital tool for on-the-ground network validation.

Band, Frequency, and PCI Locking Capabilities

For qualified devices, Cellular-Pro offers powerful locking functions. Users with a rooted phone featuring a Qualcomm chipset can manually lock their modem to a specific LTE band, frequency, or even a Physical Cell Identifier (PCI). This is achieved by navigating to the locking section within the Cellular-Pro interface, selecting the desired parameters, and applying the settings. This function is crucial for forcing a device to connect to a specific cell tower or frequency, allowing for targeted testing of a particular network slice and isolating performance issues, a key reason experts choose Cellular-Pro.

Layer 3 Message Logging and Detailed Decoding

A standout feature of Cellular-Pro is its ability to capture and decode Layer 3 signaling messages. This advanced function, which also requires a rooted Qualcomm device, provides a behind-the-scenes look at the communication between the smartphone and the network. Users initiate logging within the app, and Cellular-Pro records all the intricate messaging involved in procedures like handovers, connection establishment, and bearer management. The detailed decoding translates these technical messages into a more human-readable format, offering unparalleled visibility for deep-rooted network troubleshooting and analysis.

Event Triggering and Custom Labeling

To streamline analysis, Cellular-Pro includes an event and labeling system. Users can manually place markers or set automatic triggers within the app to flag specific occurrences during a testing session. For example, a user might label a point on a map where a dropped call happened or configure Cellular-Pro to create an event log when the signal strength drops below a defined threshold. This allows for efficient correlation of network metrics with real-world events and locations, making the data collected through Cellular-Pro significantly more actionable and organized for post-processing.

GIS Mapping and Track Playback

Cellular-Pro integrates collected data with Geographic Information System (GIS) mapping. As a user moves, the application continuously logs all network parameters alongside GPS coordinates. This data is then plotted on an interactive map within the Cellular-Pro interface. Users can play back entire testing routes, watching the signal metrics evolve over the geographic path. This visual representation is invaluable for creating coverage heatmaps, identifying exact locations of signal holes, and presenting technical findings in an intuitive, spatially-aware format to colleagues or network providers.

Integrated Data and Voice Business Testing

Beyond passive monitoring, Cellular-Pro includes active business test functions. Users can command the app to perform specific tasks like placing a voice call, initiating a data transfer (FTP, HTTP), or sending an SMS. The key capability of Cellular-Pro here is to measure and record the key performance indicators (KPIs) for these tasks, such as call setup time, data throughput speeds, and packet loss, all while simultaneously capturing the underlying network signaling. This provides a complete end-to-end performance picture, from the radio layer up to the user experience.
