Lt. Fred Mestas of the Oakland Police Department remembers the day he was face to face with a robbery suspect who looked like he was carrying a concealed shotgun. When he went to his radio for backup he saw that he had no signal.
He was in a dead spot. His transmission was ‘somehow’ blocked.
This story was just this fall. Despite an $18 million system he could not use his communication device.
The dead zones extend to hundreds of buildings including the basement of police headquarters!
