Product Configuration

NOMAD consists of a low-cost, off-the-shelf Software Defined Radio (SDR), which captures raw cellular signals across a 70MHz to 6GHz band and passes the data to a laptop running the signal analysis and a time series database.

Easy-to-Use, Comprehensive Displays & Controls

Hierarchical navigation for aggregate base station data or individual client analysis. NOMAD supports a deep set of analysis functions, with several examples described below.

A computer screen displaying a network monitoring interface titled 'Lutris Live Network Load.' The interface shows various controls and filters on the left and top, a list of network sessions with start times, durations, causes, and other details in the middle, with numerous rows indicating network failures labeled as 'otherFailure' or 'handoverFailure' in red. Blue annotations point out top-level controls, cause filters labeled 'Failures,' and failure cause details such as 'Handover.'

Base Station Monitoring

Aggregate Base Station Data

- Comprehensive visualization & control options

- Base station network load

- Band observed

- Select filters for desired information

Example: Failures displays all client failures

TMSI failure list
Failure cause
Uplink/downlink information
Measurement start time & duration

A digital graph showing spectral efficiency over time, with blue and pink lines representing uplink and downlink spectral efficiency, respectively.

Scan Mode

- SCAN/PAUSE control

- Select metric with the pulldown menu

Example: Average Spectral Efficiency for uplink & downlink

Client Monitoring

Graph displaying total bytes transferred per second over time, with separate uplink (blue) and downlink (pink) lines, and data logs on the right.

Individual Client Information

- Presence & location of client

- Quality of client connection & impairments

- Scheduler behavior & utilization
