RANGING NULL DATA PACKETS FOR WIDE BANDWIDTH NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18054531 titled 'RANGING NULL DATA PACKETS FOR WIDE BANDWIDTH NETWORKS
Simplified Explanation
The disclosure describes methods, components, devices, and systems for ranging measurement procedures between two wireless devices in wide bandwidth networks, specifically focusing on null data packet (NDP) transmissions via a 320 MHz bandwidth.
- Wireless devices communicate in wide bandwidth networks
- Ranging measurement procedures involve exchanging NDPs
- Devices indicate a 320 MHz ranging NDP via preamble bits
- Preamble bits are included in the U-SIG field of the PDU
Potential Applications
This technology could be applied in:
- Wireless communication systems
- Indoor positioning systems
- Autonomous vehicles
- Industrial automation
Problems Solved
This technology solves issues related to:
- Accurate distance measurements between wireless devices
- Efficient communication in wide bandwidth networks
Benefits
The benefits of this technology include:
- Improved ranging measurement accuracy
- Enhanced communication reliability
- Increased efficiency in data transmission
Potential Commercial Applications
This technology could be commercially applied in:
- IoT devices
- Smart home systems
- Telecommunications infrastructure
- Automotive industry
Possible Prior Art
One possible prior art could be the use of ranging measurements in wireless communication systems, but the specific implementation of NDP transmissions via a 320 MHz bandwidth may be novel.
Unanswered Questions
1. How does this technology impact battery life in wireless devices? 2. Are there any potential security concerns related to the exchange of NDPs in ranging measurement procedures?
Original Abstract Submitted
This disclosure provides methods, components, devices and systems for ranging measurement procedures between two wireless devices that communicate in wide bandwidth networks. Some aspects more specifically relate to null data packet (NDP) transmissions via a 320 megahertz (MHz) bandwidth. In some examples, a first wireless device and a second wireless device may participate in a ranging measurement procedure and may exchange one or more NDPs to facilitate distance measurements and one or both of the first wireless device and the second wireless device may indicate that an associated protocol data unit (PDU) is a 320 MHz ranging NDP (e.g., an NDP of a ranging variant associated with a bandwidth of 320 MHz) via one or more bits of the preamble of the PDU. The one or more bits may be included in a universal signal (U-SIG) field of the preamble of the PDU.
