Solution Overview
Problem
Conventional wireless communications circuitry in electronic devices is limited to a single communications band, restricting bandwidth and data throughput, and is unable to efficiently handle multiple wireless base stations, leading to reduced performance as the device moves further from the base station.
Innovation Solution
The implementation of wireless communications circuitry with multiple transmitters and receivers, coupled with antenna structures and switching circuitry that can switch between multiple frequency bands in real time, allowing simultaneous transmission and reception of data streams from multiple wireless base stations using a Long-Term-Evolution (LTE) protocol, and the cloning of connection settings between base stations to establish simultaneous connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communications circuitry is configured to convey radio-frequency signals over a selected communications band with a single wireless base station, then device complexity is reduced, but bandwidth and data throughput are limited
Solution Approach 1:
The wireless communications circuitry is configured to simultaneously support multiple communications bands and multiple wireless base stations. The filtering circuitry includes multiple bandpass filters for different bands, and the switching circuitry enables selective connection to multiple base stations, allowing the device to function across multiple frequency bands and with multiple base stations concurrently, thereby increasing bandwidth and data throughput without proportionally increasing device complexity
Solution Approach 2:
The wireless communications circuitry is divided into separate functional components: multiple transmitters, multiple receivers, and filtering circuitry with multiple bandpass filters for different frequency bands. This segmentation allows independent optimization of each component and enables simultaneous operation across multiple bands while maintaining manageable system complexity
2Device complexity
If a single wireless base station is used for wireless communications operations, then device complexity is reduced, but data throughput is limited when the device moves to locations at greater distances from the base station
Solution Approach 1:
The device merges connections to multiple wireless base stations simultaneously. The switching circuitry enables the device to maintain active connections with multiple base stations across different frequency bands, combining the capacity of multiple base stations to provide sustained data throughput even when the device is at greater distances from any single base station
Solution Approach 2:
The system changes the parameter of base station connectivity from single-point connection to multi-point connection. By configuring the wireless communications circuitry to simultaneously communicate with multiple base stations on different frequency bands, the system maintains data throughput across varying distances by dynamically utilizing multiple base stations rather than being limited to a single base station
3Productivity
If wireless communications circuitry handles signals in multiple frequency bands simultaneously, then bandwidth and data throughput are improved, but device complexity increases
Solution Approach 1:
The wireless communications circuitry is segmented into distinct functional blocks: multiple transmitters, multiple receivers, and filtering circuitry with separate bandpass filters for each frequency band. This segmentation allows each component to be optimized independently and simplifies the overall system architecture, enabling multi-band operation without proportionally increasing complexity
Solution Approach 2:
The switching circuitry serves as a universal component that enables selective connection between the transmitters/receivers and multiple base stations across different frequency bands. This multi-functional switching component consolidates the complexity of multi-band, multi-base-station communication into a single manageable element rather than requiring separate dedicated paths for each combination

AI summary
An electronic device has wireless communications circuitry. The wireless circuitry may transmit and receive wireless signals over a network having first and second wireless base stations. The first base station may establish a primary wireless connection with the device using selected connection settings and may transmit the selected connection settings to the second base station. The second base station may copy the received connection settings to establish a secondary wireless connection with the device while the primary connection is simultaneously maintained. After the primary and secondary connections have been established, the first and second base stations may transmit data streams to the electronic device over different frequency bands in a carrier aggregation link. By using the second base station to copy the received connection settings that were used by the first base station to establish the primary connection, the connection time for establishing the carrier aggregation link may be improved.
