DECT ULE Range Extender Link Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing DECT ULE repeaters increase the power consumption of portable devices in home automation networks by requiring end-to-end links for wireless communication, which is inefficient and drains battery life.
Innovation Solution
A method and device for extending the range of wireless communication in home automation networks without increasing power consumption, by using a range extender that receives an uplink message from a portable device via a first link, releases the link, stores the message, and transmits it to the base station via a second link when available, thereby eliminating the need for concurrent links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If DECT repeaters are used to relay messages between portable device and base station, then wireless communication range is extended, but power consumption of portable device increases
Solution Approach 1:
The patent introduces a range extender as an intermediary device that receives messages from the portable device via a first link and transmits them to the base station via a second link. This mediator eliminates the need for the portable device to maintain concurrent end-to-end links, thereby extending communication range while keeping the portable device's power consumption low.
Solution Approach 2:
The communication path is segmented into two separate links: a first link between the portable device and the range extender, and a second link between the range extender and the base station. This segmentation allows the portable device to release the first link after transmission without needing to maintain an end-to-end connection, reducing its power consumption while still achieving extended range communication.
2Reliability
If end-to-end link is maintained for message transmission, then reliable communication is achieved, but link release and re-establishment increases power consumption
Solution Approach 1:
The range extender performs preliminary actions by establishing and maintaining the second link with the base station in advance. When a message needs to be transmitted, the portable device only needs to establish the first link with the range extender, which is a simpler and faster process. This preliminary setup eliminates the need for the portable device to perform complex end-to-end link establishment and maintenance, reducing its power consumption while ensuring reliable communication through the pre-established second link.

AI summary
This disclosure provides methods, devices, and systems for wireless communications. The present implementations more specifically relate to range extenders for digital enhanced cordless telecommunications (DECT) ultra low energy (ULE) home automation networks (HANs) that can extend the range of wireless communications without increasing the power consumption of portable devices. In some aspects, a ULE range extender may include a fixed part (FP) component configured to communicate with one or more portable devices, and a portable part (PP) component configured to communicate with a base station. In some implementations, the FP component may receive an uplink message from a portable device via a first link and may immediately release the first link upon receiving the uplink message. The PP component transmits the uplink message to the base station via a second link and releases the second link upon receiving confirmation that the uplink message has been received by the base station.
