Solution Overview
Problem
Current wireless LAN broadcast methods face challenges in efficiently transmitting large amounts of data in a short time, as modulation methods with high transmission rates often result in data unreceptibility by clients, while low transmission rate methods are inefficient.
Innovation Solution
A wireless transmitting device and method that sequentially transmits frames using multiple modulation and coding schemes (MCSs), including both high and low transmission rate methods, to ensure data is received by clients across varying distances and environments.

1Productivity
If a modulation method with high transmission rate is used, then data transmission speed is improved, but data reception reliability deteriorates
Solution Approach 1:
The transmission data is divided into multiple frames, and each frame is transmitted using a different modulation method. This segmentation allows the system to use high transmission rate modulation for some frames and low transmission rate modulation for others, thereby balancing transmission speed and reception reliability across different client devices.
Solution Approach 2:
Different modulation methods are applied to different frames based on the specific requirements and reception capabilities of client devices. This local quality approach ensures that each frame is transmitted with the most appropriate modulation method for its intended recipients, optimizing both speed and reliability for different data segments.
2Reliability
If a modulation method with low transmission rate is used, then data reception reliability is improved, but data transmission efficiency deteriorates
Solution Approach 1:
By segmenting transmission data into multiple frames and assigning different modulation methods to each frame, the system can use low transmission rate modulation only for frames requiring high reliability, while using high transmission rate modulation for other frames, thereby maintaining overall transmission efficiency.
Solution Approach 2:
The system dynamically changes modulation parameters (transmission rate) for different frames based on client device capabilities and channel conditions. This parameter change allows the system to optimize the balance between reliability and efficiency by selecting appropriate modulation methods for each frame rather than using a single fixed rate for all transmissions.

AI summary
A wireless transmitting system acquires transmission data, sequentially transmits, by broadcast, a plurality of frames contained in the acquired transmission data, that are modulated by any of a plurality of modulation and coding schemes (MCSs) including a first MCS and a second MCS, and controls to transmit a first frame that is modulated by the first MCS based on the acquired transmission data and then to transmit a second frame that is modulated by the second MCS based on the acquired transmission data.
