Whether it is passengers or freight, the transportation industry must deliver cargo at the right place and time, in a secure manor. Maintaining wireless connectivity for the mobile workforce, critical systems and devices is critical. With consistent end-to-end connectivity, logistics and security efforts are simplified.

Observances

• Highlight locations with low or no signal strength.• Identify locations where measurements are different than the expectation.

ResultsData, complete with time stamps and location information are displayed on a map, to assist the operator with identifying areas in need of service, or with interference.

Observance

• Occupancy, RSS and Modulation information for multiple operators

ResolutionMetrics utilized to determine which channels (and at what times) were available for utilization. Modulation type, along with radio ID’s (when available), were provided to confirm the observed activity was consistent with communications.
