Antenna Ping Function Multiplexer Sharing OOK Modems

Solution Overview

Problem

Existing antenna systems require multiple modem chips for each RF port to perform the antenna Ping function, leading to increased space occupation, power consumption, and costs.

Innovation Solution

A device comprising a primary module and a secondary module, where a multiplexer and OOK modems are used to share the Ping function across multiple RF ports, reducing the number of OOK modems needed and incorporating a SMA interface for signal shielding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each antenna RF port is assigned a dedicated modem chip, then the antenna Ping function can be reliably implemented, but the space occupied in the antenna increases and power consumption increases

Engineering Contradiction:

Improveantenna Ping function reliabilityVSAvoidspace occupied in antenna

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent merges multiple modem chip functions into a single shared modem chip that can serve multiple antenna RF ports. The modem chip is configured to communicate with multiple antenna RF ports through a control mechanism that enables time-division or signal-division multiplexing, allowing one modem chip to perform Ping functions for multiple antennas simultaneously, thereby reducing the total number of modem chips required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The modem chip is designed with universal functionality to handle communications with multiple antenna RF ports. It includes multiple interfaces or communication paths that can be dynamically assigned to different RF ports, enabling a single modem chip to perform the Ping function for multiple antennas rather than requiring dedicated chips for each port.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If each antenna RF port has a dedicated modem chip, then the antenna Ping function is ensured, but the overall power consumption of the antenna increases

Engineering Contradiction:

Solution Approach 1:

The patent merges multiple modem chip functions into a single shared modem chip that can serve multiple antenna RF ports. The modem chip is configured to communicate with multiple antenna RF ports through a control mechanism that enables time-division or signal-division multiplexing, allowing one modem chip to perform Ping functions for multiple antennas simultaneously, thereby reducing the total number of modem chips required.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system employs periodic or cyclic inspection mechanisms where the single modem chip sequentially performs Ping functions on different antenna RF ports in a time-division manner. This periodic inspection approach allows the modem chip to service multiple ports without requiring continuous operation of multiple dedicated chips, thereby reducing overall power consumption while maintaining reliability.

AI summary

A device for implementing an antenna Ping function includes a primary module and a secondary module. The secondary module includes a secondary controller, a multiplexer, a first On-Off Keying (OOK) modem, a second OOK modem connected to the secondary controller and a corresponding multiplexer, and a plurality of antenna radio frequency (RF) ports. The multiplexer is connected to the plurality of antenna RF ports. The primary module is connected to the secondary controller through the first OOK modem. The primary module receives a Ping command transmitted by a base station, generates a Ping message, and transmits the Ping message to the secondary controller through the first OOK modem. The secondary controller transmits the received Ping message to the second OOK modem. The second OOK modem transmits the Ping message to a corresponding antenna RF port through the multiplexer. The antenna RF port feeds back a signal to the base station.
