Abstract

A radio unit (101) is being located relative to a plurality of radio anchors (102). The radio anchors are radio units with known locations. The radio unit and the radio anchors are arranged to send or receive signals (103). Neighboring radio anchors are grouped into anchor groups (104), and a region (105) is associated to each anchor group. The region is situated near the radio anchors of the anchor group and within a localization area (106). Signal strengths (107) are measured between the radio unit and the radio anchors. The signal strengths of radio anchors of each anchor group are combined into a respective group strength. At least one anchor group is determined based on the group strength of the anchor group relative to other group strengths. The region associated to the determined anchor group is selected as the estimated location of the radio unit.
