Wireless Repeater Chain Frequency Band Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for redirecting User Equipment (UE) to supported frequencies in a wireless repeater chain are neither efficient nor effective, as not all repeaters in the chain can support all frequency bands and channels used by the wireless network access point.
Innovation Solution
A wireless communication system redirects UE from a source frequency band to a target frequency band by using an originating repeater to transmit modified source overhead, indicating redirection, which is received and re-broadcast by a terminating repeater, allowing seamless frequency band switching within the repeater chain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If repeaters are added to expand wireless signal coverage, then coverage area is improved, but frequency band compatibility deteriorates (not all repeaters can support all frequency bands)
Solution Approach 1:
The patent introduces network overhead messages as an intermediary mechanism to facilitate communication between repeaters of different frequency bands. The originating repeater sends source network overhead on the source frequency band, which is relayed through intermediate repeaters to the terminating repeater that modifies it with target frequency band information. This intermediary message passing system enables frequency band translation without requiring all repeaters to support all bands directly.
Solution Approach 2:
The patent segments the frequency band translation function into distinct roles: originating repeaters that send source network overhead, intermediate repeaters that relay signals, and terminating repeaters that modify overhead with target frequency information. This segmentation allows each repeater type to be optimized for specific frequency bands while collectively providing broad coverage across multiple bands.
2Adaptability or versatility
If current redirection methods are used for frequency band translation, then frequency redirection is achieved, but efficiency and effectiveness deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the terminating repeater modifies the source network overhead with target frequency band information and sends it back through the repeater chain to UEs. This feedback loop ensures that UEs receive accurate redirection information about which frequency bands are supported by repeaters in their vicinity, enabling efficient frequency band switching without trial-and-error attempts.
Solution Approach 2:
The patent performs preliminary action by having the terminating repeater pre-modify the network overhead with target frequency band information before UEs attempt to connect. This advance preparation of redirection information allows UEs to proactively switch to supported frequency bands before connection failures occur, improving redirection efficiency compared to reactive methods.

AI summary
A wireless communication network redirects User Equipment (UE) from a source frequency band to a target frequency band. An originating wireless repeater in a wireless repeater chain wirelessly receives wireless source signals including source overhead over the source frequency band and wirelessly receives wireless target signals including target overhead over the target frequency band. The originating wireless repeater wirelessly transmits the wireless source signals including the source overhead over the source frequency band and wirelessly transmits the wireless target signals including the target overhead over the target frequency band. A terminating wireless repeater in the wireless repeater chain wirelessly receives the wireless target signals including the target overhead over the target frequency band and wirelessly transmits the wireless target signals including the target overhead over the target frequency band. The terminating wireless repeater wirelessly transmits modified source overhead over the source frequency band indicating redirection to the target frequency band.
