A physical location that suffers from severe signal attenuation or blocking, leaving mobile devices unable to connect to the network. These dead zones are typically caused by terrain masking, dense building materials, or destructive multipath interference. Network planners hunt these down using drive-testing equipment to optimize antenna tilt or justify adding a new microcell.
