Wireless Coexistence via Beacon Time Interval Reservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems using the 2.4 GHz frequency band, such as IEEE 802.11 and Bluetooth, often experience interference and lack compatibility with third-party devices due to proprietary and manufacturer-specific coexistence techniques, limiting the use of third-party components and causing interference between different communication protocols operating on the same frequency band.
Innovation Solution
The system synchronizes wireless units with a central access point by seeding time values into the beacon, allowing for the coexistence of different communication protocols within the same frequency band by reserving specific time intervals for exclusive use, enabling third-party devices to operate without interference.

1Object-affected harmful factors
If proprietary coexistence techniques are used, then interference between protocols is reduced, but compatibility with third-party devices is lost
Solution Approach 1:
The patent introduces a mediator component that translates between proprietary coexistence protocols and standard wireless protocols. This intermediary layer enables third-party devices to participate in the coexistence mechanism without requiring manufacturer-specific implementations, thus resolving the contradiction between reducing interference and maintaining compatibility.
Solution Approach 2:
The patent creates a universal coexistence mechanism that can handle multiple protocol types (802.11, Bluetooth, etc.) through a single standardized interface. This multi-functional approach allows any third-party device to join the coexistence system regardless of its native protocol, eliminating the need for proprietary implementations while maintaining interference management capabilities.
2Productivity
If frequency hopping is used at high rates, then protocol-specific performance is optimized, but interference with other protocols increases
Solution Approach 1:
The patent implements periodic time intervals within the beacon frame that are dedicated to specific protocol operations. By creating regular, predictable periods for 802.11 communications and Bluetooth communications, the system maintains high protocol-specific performance while reducing random interference through structured temporal separation.
Solution Approach 2:
The patent dynamically adjusts the timing and duration of protocol-specific intervals based on current network conditions and protocol requirements. This dynamic allocation allows the system to optimize performance for active protocols while minimizing interference to inactive or low-priority protocols, adapting in real-time to changing usage patterns.

AI summary
A computing arrangement may include a first radio transceiver operating in accordance with a first communication protocol using a frequency band and a second radio transceiver operating in accordance with a second communication protocol using the frequency band. An access point operates in accordance with the first communication protocol and transmits a communication signal that has a frame including a first time interval indicative of when communications using the first communication protocol via the frequency band are permitted to the computing arrangement. The computing arrangement determines if the frame includes a second time interval, which is indicative of and is reserved for exclusive communications in accordance with the second communication protocol. If the second time interval is absent from the frame, the computing arrangement inserts the second time interval into the frame. The computing arrangement communicates with a further device only during the second time interval.
