Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Previous generations of fixed wireless networks were unpopular due to high costs, use of proprietary technology, and low data rates, making them unsuitable for providing broadband services to areas without wired connections.
Innovation Solution
Customer premises equipment (CPE) that enables fixed wireless broadband services by receiving broadband services wirelessly from an LTE network based on the 3GPP standard, eliminating the need for satellite network communication, and providing these services at a lower cost and reduced complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional satellite network setups are used for fixed wireless broadband services, then broadband services can be provided to areas without wired connections, but the cost and complexity increase significantly
Solution Approach 1:
The patent introduces an LTE network as an intermediary between the service provider and the customer premises equipment. Instead of directly connecting to complex satellite networks, the CPE uses standard LTE wireless communication to access broadband services, significantly simplifying the overall system architecture while maintaining the ability to serve areas without wired connections.
Solution Approach 2:
The patent changes the fundamental communication parameter from satellite-based radio frequency communication to LTE-based wireless communication. This parameter change enables the use of standardized, commercially available LTE infrastructure and devices, thereby reducing complexity and cost while maintaining broadband service delivery to remote areas.
2Area of stationary object
If expensive network equipment and proprietary technology are used for fixed wireless networks, then network coverage can be extended to remote areas, but the cost and installation complexity increase
Solution Approach 1:
The patent leverages the universal LTE network infrastructure that is already deployed for mobile communications. By using this existing universal platform, the system can provide broadband services to remote areas without requiring dedicated expensive satellite equipment or proprietary technology, thereby reducing installation and equipment costs while maintaining extensive network coverage.
Solution Approach 2:
The patent uses standardized LTE technology that is already widely deployed and understood, effectively copying the success of mobile LTE networks to fixed wireless broadband applications. This approach avoids the need to develop new proprietary technologies or use expensive specialized equipment, significantly reducing costs while maintaining the ability to cover remote areas.
3Device complexity
If low data rates are used in fixed wireless networks, then network infrastructure can be simplified, but the service quality and usability deteriorate
Solution Approach 1:
The patent changes the data rate parameter by leveraging the high-speed capabilities of LTE technology. Instead of accepting low data rates that would simplify infrastructure, the system uses LTE's inherent high data rate capabilities to provide quality broadband service while keeping the infrastructure relatively simple through the use of standard wireless communication protocols and existing network elements.

AI summary
An indoor broadband device receives, from a user device, a first request for content; determines a quality of service (QoS) level at which the content is to be provided to the user device; provides a second request for the content, at the determined QoS level, to a wireless access network, the wireless access network connecting to a network that provides broadband services; receives, based on the second request, the content, at the determined QoS level, from the wireless access network; processes the content in a manner that conforms to the QoS level and in a format that is supported by the user device; and provides the content to the user device.
