Abstract

An Unmanned Aerial Vehicle (UAV)-based method of wireless coverage testing includes with a UAV comprising a wireless coverage testing configuration, flying the UAV in a route in a wireless coverage area associated with a cell tower; collecting measurement data via the wireless coverage testing configuration during the flying and associated with collected measurement data with location identifiers; and, subsequent to the flying, processing the collected measurement data with the location identifiers to provide an output detailing wireless coverage in the wireless coverage area including wireless coverage at ground level and above ground level to a set elevation.

First claim

What is claimed is:

1 . An Unmanned Aerial Vehicle (UAV)-based method of wireless coverage testing, the UAV-based method comprising:
with a UAV comprising a wireless coverage testing configuration, flying the UAV in a route in a wireless coverage area associated with a cell tower; collecting measurement data via the wireless coverage testing configuration during the flying and associating the collected measurement data with location identifiers; and subsequent to the flying, processing the collected measurement data with the location identifiers to provide an output detailing wireless coverage in the wireless coverage area including wireless coverage at ground level and above ground level to a set elevation.

2 . The UAV-based method of claim 1 , wherein the wireless coverage testing configuration comprises one or more devices comprising any of wireless antennas, wireless scanners, Wireless Local Area Network (WLAN) antennas, and one or more mobile devices, communicatively coupled to a processing device, and each of the one or more devices disposed in or on the UAV.

3 . The UAV-based method of claim 2 , wherein each of the one or more devices is positioned a minimum distance from one another to prevent interference.

4 . The UAV-based method of claim 2 , wherein the UAV comprises a frame disposed thereto with the one or more devices attached thereto with a minimum distance from one another to prevent interference.

5 . The UAV-based method of claim 1 , wherein the location identifiers comprise at least two independent location identification techniques thereby improving accuracy thereof.

6 . The UAV-based method of claim 1 , wherein each subsequent of the flying steps for additional wireless coverage testing is performed with the UAV taking off and landing at a same location and orientation at a cell site associated with the cell tower.

7 . The UAV-based method of claim 1 , wherein the route comprises a substantially circular pattern at a fixed elevation about the cell tower.

8 . The UAV-based method of claim 1 , wherein the route comprises a substantially circular pattern at a varying elevations about the cell tower.

9 . The UAV-based method of claim 1 , wherein the wireless coverage testing configuration is configured to measure a plurality of Signal intensity, Signal quality, Interference, Dropped calls, Blocked calls, Anomalous events, Call statistics, Service level statistics, Quality of Service (QoS) information, Handover information, and Neighboring cell information.

10 . The UAV-based method of claim 1 , wherein the route comprises locations between handoffs with adjacent cell towers.

11 . The UAV-based method of claim 1 , further comprising:
subsequent to the flying and prior to the processing, flying the UAV in a second route in a second wireless coverage area associated with a second cell tower; and collecting second measurement data via the wireless coverage testing configuration during the flying the second route and associating the collected second measurement data with second location identifiers.

12 . An Unmanned Aerial Vehicle (UAV) adapted for wireless coverage testing, the UAV comprising:
one or more rotors disposed to a body; wireless interfaces; a wireless coverage testing configuration; a processor coupled to the wireless interfaces, the one or more rotors, and the wireless coverage testing configuration; and memory storing instructions that, when executed, cause the processor to:
cause the UAV to fly in a route in a wireless coverage area associated with a cell tower;
collect measurement data via the wireless coverage testing configuration during the flight and associate the collected measurement data with location identifiers; and
subsequent to the flight, provide the collected measurement data with the location identifiers for processing to provide an output detailing wireless coverage in the wireless coverage area including wireless coverage at ground level and above ground level to a set elevation.

13 . The UAV of claim 12 , wherein the wireless coverage testing configuration comprises one or more devices comprising any of wireless antennas, wireless scanners, Wireless Local Area Network (WLAN) antennas, and one or more mobile devices, communicatively coupled to a processing device, and each of the one or more devices disposed in or on the UAV.

14 . The UAV of claim 13 , wherein each of the one or more devices is positioned a minimum distance from one another to prevent interference.

15 . The UAV of claim 13 , wherein the UAV comprises a frame disposed thereto with the one or more devices attached thereto with a minimum distance from one another to prevent interference.

16 . The UAV of claim 12 , wherein the location identifiers comprise at least two independent location identification techniques thereby improving accuracy thereof.

17 . The UAV of claim 12 , wherein each subsequent of the flight for additional wireless coverage testing is performed with the UAV taking off and landing at a same location and orientation at a cell site associated with the cell tower.

18 . The UAV of claim 12 , wherein the route comprises one of a substantially circular pattern at a fixed elevation about the cell tower and a substantially circular pattern at a varying elevations about the cell tower.

19 . The UAV of claim 12 , wherein the wireless coverage testing configuration is configured to measure a plurality of Signal intensity, Signal quality, Interference, Dropped calls, Blocked calls, Anomalous events, Call statistics, Service level statistics, Quality of Service (QoS) information, Handover information, and Neighboring cell information.

20 . The UAV of claim 12 , wherein the route comprises locations between handoffs with adjacent cell towers.
