Abstract There are major development/building works to be carried out near the DLR station at Gallions Reach on Atlantis Avenue which have the potential to affect the radio coverage of the DLR radio system. A survey of current signal levels in the area from Canning Town to Beckton DLR Stations was commissioned by Telford Homes to provide a base line RF level Survey to allow the impact of building works to be assessed as the development works are carried out. This document details the results of the survey carried out in April 2021. 6.
