Apple might have abandoned its ambitious dreams for the Apple Car, but the project's ethos-laden spirit apparently lives on in the form of a secretive drone project, as hinted within a recent patent application filed by the Cupertino-based tech giant.
Apple's patent tackles the very real challenge of network congestion, which can be spurred by a swarm of drones that constantly exchange information with cell towers
Apple has now filed a patent application that aims to tackle the core network congestion problems emanating from a swarm of drones.
Drones typically communicate a vast array of information to nearby cell towers as their altitude and position changes, including:
- RSRP - Reference Signal Received Power (signal strength).
- RSRQ - Reference Signal Received Quality (signal quality).
- SINR - Signal to Interference plus Noise Ratio (signal clarity vs. noise).
- Beam Reports: Precise antenna targeting details.
As drones upload these huge files to all of the network towers that are in close proximity, the protocol creates a massive signalling overhead, resulting in network congestion.
Apple is now aiming to resolve this drone-led network congestion problem in three ways. Firstly, when a simple cellular network "event" occurs, such as a handoff from 5G to 4G or vice versa, the Apple drone would only communicate a simple Cell ID - the unique identifier of the pertinent cell tower - instead of uploading the massive RSRP, RSRQ, and SINR data logs.
Secondly, Apple envisions the creation of a threshold for uploading the full gamut of data logs. For instance, the Apple drone can keep a track of how many cell towers it is communicating with over a set period. A full data upload only occurs once the live tracker detects that the preset threshold for new data towers has been met.
Thirdly, this threshold can be further refined by assigning a specific frequency to a given data log and then tracking the oncoming demand for uploads. This is akin to using one universal alarm for all cellular frequencies instead of creating individual alarms. Once the coded threshold is met, the Apple drone would upload a single, comprehensive report, eliminating the need for constant, erratic reporting.
This patent presents a practical way for a theoretical swarm of drones from Apple to communicate with the cell towers in an efficient manner. While the patent itself is not an indication that the launch of an Apple drone line is imminent, it does show that the tech giant is investing time and resources into resolving practical challenges that come with operating drone swarms.
