Frequency Hopping Channel Reservation for High Bandwidth Data Bursts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frequency hopping communication protocols in building automation systems do not effectively facilitate high bandwidth communication bursts, leading to inefficiencies in data transmission.
Innovation Solution
A frequency hopping communication protocol that allows a host device to create and manage a sequence of predetermined frequencies, reserving specific channels for high bandwidth communications while maintaining routine messaging through other channels, enabling efficient cycling through the frequency sequence to prioritize high bandwidth requests without disrupting lower bandwidth communications.

Engineering Contradiction Analysis
1Reliability
If a frequency hopping protocol is used for wireless communication between devices, then communication reliability is improved through frequency diversity, but bandwidth capacity deteriorates due to sequential frequency access
Solution Approach 1:
The frequency hopping sequence is divided into multiple channels, where each channel consists of a subset of frequencies from the complete hopping sequence. This segmentation allows simultaneous establishment of multiple communication paths, enabling parallel data transmission and thus increasing overall bandwidth capacity while maintaining the reliability benefits of frequency diversity.
Solution Approach 2:
The protocol enables continuous high-bandwidth communication by maintaining active frequency channels without requiring devices to sequentially hop through all frequencies. The host device can continuously transmit and receive data on reserved channels while client devices remain synchronized, eliminating idle time and maximizing useful communication action.
2Productivity
If channels are reserved for high bandwidth communications, then data transmission efficiency is improved, but access flexibility deteriorates for routine messaging
Solution Approach 1:
The channel reservation system is dynamic rather than static. The host device can allocate specific channels for high-bandwidth communications when needed, while other channels remain available for routine messaging. This dynamic allocation allows the system to adapt to varying communication demands, providing both high transmission efficiency for data-intensive applications and flexible access for routine interactions.
Solution Approach 2:
Different channels within the frequency hopping sequence are assigned different functional qualities. Some channels are optimized and reserved for high-bandwidth data transmission, while other channels maintain general-purpose access for routine messaging. This local differentiation of channel qualities allows simultaneous optimization for both high-speed data transfer and flexible communication access.

AI summary
A building automation system includes a host device and a plurality of client devices that can communicate with the host device via a frequency hopping protocol. The host device is configured to create and/or store a frequency hopping sequence including a plurality of ordered predetermined frequencies, and listens for communications from the plurality of client devices. Each cycle through the frequency hopping sequence is considered to be a channel. The host device may define a plurality of channels, with some of the plurality of channels reserved for routine messaging between the host device and the plurality of client devices and some of the plurality of channels reserved at times for higher bandwidth data communications.
