The most important facts about 5G

Transfer rates up to 10 GBit/s

Latency times below one millisecond

Real-time transmission, 100 billion mobile devices can be addressed simultaneously worldwide

Compatibility of machines and equipment

Use of higher frequency ranges up to 50GHz

Will be a revolution for everyday life in all areas of life!

The difference between a 4G and 5G Antenna

The Antenna guides the beamto the area where bandwidth is needed!

Limitation is not 8 Beams/Antenna,

Each Beam can be formed!

SSB Synchronization Signal Block one 10ms NR-Slot contains 14 OFDM- Symbols

5G NR Base Station Analyzer FunctionThe Analyzer measures the physical Cell ID (PCI) of the Base Station and the Beam ID as well as the Power SS-RSRP (SS reference signal received power) of the current location.

The only way to measure antenna performance is for the technicianto move into the radio field of the Antenna which is not always possible

These results will provide some visibility to signal strength and footprint but far from the complete picture

This is however the most important first step for accurate and complete Antenna testing!

A drone is a special solution which can fully analyze the antenna beaming and interferencesin 10% of the time

A drone will allow to measure in areas where a technician doesn’t always have full access, especially at the exact level of the Antenna or disrupting signal affecting the Antenna

Confidential and Proprietary

Measurements from the ground station, combined with drone measurements will give a clear, repeatable and most important, accurate antenna performance measurement results

At the location the technician only needs to Prepare the drone and to start the flight.

The drone takes of and the analyzer collectsthe data and send them to a server.

When this job is done the drone returnsautomatically to the start point.

The server send the result back to thetechnician on the ground
