Data Transfer Rate Estimation via Spatial Interpolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the maximum achievable data transfer rate in a network connection is challenging due to unknown transmission properties of the last link between the data network and the customer, making practical measurements impractical and effort-intensive.
Innovation Solution
The method involves determining the maximum data transfer rate for nearby connection points in a wired network by averaging, interpolating, or extrapolating based on measured rates from geographically close subscriber connections, and for wireless networks, by averaging or extrapolating data transfer rates from nearby locations, using mathematical mapping functions to estimate the rate at any given location.

Engineering Contradiction Analysis
1Measurement precision
If measurements are performed to determine the maximum achievable data transfer rate, then measurement precision is improved, but ease of operation deteriorates due to considerable effort and customer involvement required
Solution Approach 1:
The patent performs measurements at multiple preliminary locations before the actual service location to establish a spatial model of data transfer rates. By conducting these measurements in advance and creating a mathematical model of the transmission properties, the system eliminates the need for time-consuming on-site measurements when a customer actually needs service, thus improving ease of operation while maintaining measurement precision through the pre-established model.
2Reliability
If transmission properties of the last link are determined through measurements, then reliability is improved, but device complexity increases due to the measurement system requirements
Solution Approach 1:
The patent creates a mathematical model (copy) of the transmission properties based on measurements taken at multiple locations. Instead of requiring complex measurement equipment and procedures at every service location, the system uses a simplified computational model that replicates the transmission characteristics. This copying approach maintains reliability by accurately representing the physical transmission properties while dramatically reducing device complexity at the point of service.
3Adaptability or versatility
If data transfer rates are determined for multiple locations, then adaptability is improved, but loss of time increases due to the extensive measurement process
Solution Approach 1:
The patent performs measurements at multiple locations in advance to build a comprehensive spatial model of data transfer rates across the service area. By conducting these measurements preliminarily and storing the results in a mathematical model, the system enables rapid determination of appropriate service levels for any location within the coverage area without requiring time-consuming on-site measurements, thus improving adaptability while reducing time loss.

AI summary
The method involves measuring a data transfer rate at a connection point of a line network, where the connection point is in proximity with another connection point. Data transfer rate at the latter connection point is determined based on the measured data transfer rate. The former connection point is connected with a cable distributor (5a). A local area network determining point (2) is connected with a core network (3) of a network operator and is connected with an Internet or another core network of another network operator. An independent claim is also included for a data carrier with a stored program for determining a data transfer rate.
