Motorola asked the Study Group if it was possible to say whether we could use this information to infer if phone calls occur in clusters and if it was possible to determine the locations, size and other features of these clusters. The Study Group found clusters in 'signal space,' that is, handsets reporting similar signal strengths with the same base stations and explored methods of locating these clusters geographically. date: 2008 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/243/2/Motorola-DynamicClusters.pdf identifier: Hewett, David and Hicks, Peter and Howell, Peter and Fiedler, Juliusz and Ockendon, John and Pachon, Ricardo and Smith, Honora and Wilson, Eddie and Armour, Tristram (2008) Dynamic clusters (Dynamic Location of Phone Call Clusters).
