Solution Overview

Problem

Low power telemetry devices face rapid battery drain when directly transmitting data to an Evolved NodeB, and existing Evolved NodeBs have limited processing capacity, making it difficult to handle data from a large number of IoT devices.

Innovation Solution

A telemetry aggregator that receives and aggregates data frames from multiple telemetry devices, determines a preferred time and frequency for transmission, and transmits the aggregated data frame to the Evolved NodeB, optimizing power usage and processing load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If low power telemetry devices transmit data directly to eNodeB, then data transmission is enabled, but battery power drains quickly

Engineering Contradiction:

Improvebattery power consumptionVSAvoiddata transmission capability

Core Design Contradiction:

Use of energy by moving objectVSReliability

Solution Approach 1:

A gateway device is introduced as an intermediary between telemetry devices and eNodeB. The gateway receives data from multiple telemetry devices, aggregates it, and forwards to eNodeB. This reduces the transmission distance and power consumption for individual telemetry devices while maintaining reliable data transmission capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Data from multiple telemetry devices is merged/aggregated at the gateway into a single data stream before transmission to eNodeB. This consolidation reduces the number of individual transmissions required, thereby reducing overall power consumption while maintaining complete data coverage.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If eNodeB handles data from many IoT devices, then network coverage is improved, but processing capability becomes insufficient

Engineering Contradiction:

Improvenumber of connected devicesVSAvoidprocessing capability

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments the data handling function by separating aggregation tasks from processing tasks. The gateway performs data aggregation and preliminary processing, while eNodeB focuses on core network processing. This segmentation allows the network to support more devices without overwhelming the eNodeB's processing capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Data aggregation and preliminary processing are performed at the gateway before data reaches eNodeB. This preliminary action reduces the volume and complexity of data requiring eNodeB processing, enabling the system to accommodate more IoT devices while maintaining processing efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

Embodiments herein relate to a method, telemetry aggregator and system for transmitting data from a plurality of telemetry devices to an evolved nodeB (eNodeB) over wireless communication network. A telemetry aggregator (TA) is placed in between the telemetry device and the eNodeB. The TA is placed close to the power source. This ensures that even the low power telemetry devices can transmit the data over the mobile network. The TD transmits plurality of data frames to the TA. The TA aggregates and assembles the plurality of data frames into an aggregated data frame. TA then transmits the aggregated data frame to the eNodeB at a preferred time and frequency. Since the plurality of data frames are aggregated, there is no need for the eNodeB to be connected with the Internet of Things (IoT) devices or TD for the processing of the control messages and the data.
