Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Despite the use of repeaters to extend coverage in wireless communication networks, gaps in coverage and areas with low signal strength still exist, necessitating an improvement in the quality of service, particularly in areas where mobile stations frequently move between sectors.
Innovation Solution
Intelligently selecting locations for multi-service repeaters based on mobility indicators to enhance connectivity between multiple base stations, thereby improving service quality by repeating signals from multiple base stations and reducing the probability of dropped calls and providing additional bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional single-service repeaters are used to extend coverage, then the coverage area is enlarged, but gaps in coverage and areas with low signal strength still exist
Solution Approach 1:
The repeater is designed to provide multiple services by simultaneously repeating signals from multiple base stations (e.g., BTS1 and BTS2) on different frequencies. This multi-functional approach allows a single repeater to cover multiple coverage areas and eliminate gaps that would require multiple single-service repeaters, thereby improving both coverage area and signal strength quality.
2Reliability
If multiple single-service repeaters are deployed to improve coverage quality, then signal strength is improved, but the complexity of repeater placement and network configuration increases
Solution Approach 1:
Multiple single-service repeaters that would otherwise be needed to cover different base station signals are merged into a single multi-service repeater. This consolidation reduces the number of devices to be placed and configured, simplifying deployment while maintaining improved signal strength quality through multiple service capabilities.
3Reliability
If repeaters are strategically placed to eliminate coverage gaps, then coverage quality is improved, but the cost of deploying additional repeaters increases
Solution Approach 1:
A single repeater is designed to perform multiple functions by repeating signals from multiple base stations simultaneously. This multi-functional repeater replaces what would traditionally require multiple separate repeaters, thereby improving coverage quality while reducing the total quantity of repeaters needed in the network.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method effectively enhances network performance by reducing dropped calls and improving signal strength, especially during handoffs between sectors, and increases the efficiency of repeater placement, addressing gaps in coverage and low signal areas.
Implementation Method 1
The repeater may amplify the power of these intercepted signals and send amplified versions of these signals to the mobile station or the base station

AI summary
Disclosed herein is a method for selecting a location at which to implement a multi-service repeater in a radio access network. The multi-service repeater may provide service by repeating signals from multiple base stations including at least a first base station and a second base station. In addition, the radio access network may define a coverage area in which mobile stations operate. The method comprises, at each of one or more locations in the coverage area, evaluating one or more mobility indicators that provide information regarding movement of the mobile stations and, based, at least in part, on the evaluation of the mobility indicators at the one or more locations, selecting a given one of the locations where service could be improved by implementation of a multi-service repeater. Quality of service may be improved by intelligently selecting a location for the installation multi-service repeater based on mobility indicators.
