FCC Bureau Seeks Comment on Vertical Location Accuracy Report

The FCC Public Safety Bureau Monday sought comment on an August report by CTIA and the national wireless carriers on vertical accuracy (z-axis) for wireless calls to 911. The report by Location Technologies Test Bed, the test bed administrator, “describes the testing process used to assess vertical location solutions … and provides the results of the testing,” the bureau said. The report notes that two vendors, NextNav and Polaris, took part in tests. The technologies they offer “rely on barometric pressure sensor information from mobile wireless handsets to determine an estimated altitude of an indoor wireless 9-1-1 call,” the bureau said. Comments are due Oct. 1 in docket 07-114, replies Oct. 11.
