Innovation Solution
An advanced wireless IP set top box with multiple built-in antennas capable of capturing plural downstream transmissions using different modem technologies, allowing for simultaneous data reception and establishing broadband connections through negotiated channel assignments with various wireless infrastructures, such as WiMAX, LTE, and GSM, without the need for wires, and enabling proprietary frequency allocation for better bandwidth control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single modem and antenna system is used in wireless IPTV set top boxes, then device complexity is reduced, but reliability and adaptability to different wireless infrastructures deteriorate
Solution Approach 1:
The patent divides the wireless communication system into separate modem modules (first modem for WiMAX, second modem for cellular) and antenna modules (first antenna for WiMAX, second antenna for cellular). This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability through redundancy and multi-path connectivity.
Solution Approach 2:
The set top box is designed with multi-functionality by incorporating multiple modems and antennas that can operate with different wireless infrastructures (WiMAX, cellular networks). This universal design enables the device to adapt to various network types and conditions, ensuring reliable IPTV service delivery regardless of the available wireless infrastructure.
2Adaptability or versatility
If multiple modems and antennas are integrated into the set top box, then adaptability to different wireless infrastructures is improved, but device complexity increases
Solution Approach 1:
The patent segments the wireless communication functionality into distinct modem and antenna pairs, where the first modem communicates with the first antenna for WiMAX operations, and the second modem communicates with the second antenna for cellular operations. This modular segmentation simplifies the integration process and makes the system more manageable despite the increased number of components.
Solution Approach 2:
The system dynamically selects and switches between different modem-antenna pairs based on the available wireless infrastructure and service requirements. This dynamic adaptability allows the set top box to optimize its configuration for current operating conditions, managing complexity through intelligent resource allocation rather than static hardware design.
3Reliability
If proprietary frequency allocation is implemented, then bandwidth control and quality of service are improved, but device complexity and regulatory compliance challenges increase
Solution Approach 1:
The patent implements proprietary frequency allocation by changing the operational parameters of the modems and antennas to use specific frequency bands allocated for IPTV services. This parameter change enables dedicated bandwidth control and quality of service guarantees while the system automatically manages the complexity of frequency coordination through integrated control mechanisms.
