The National Radio Systems Committee, a standards body, wrote of one test that "the digital signal remains robust and unimpaired [when] analogue reception is severely compromised".To station owners, the advantage of IBOC is that it does not require new transmitters or additional licences.
And if digital reception is somehow obstructed, the IBOC chip can switch back to analogue, which tolerates weak or reflected signals.To station owners, the advantage of IBOC is that it does not require new transmitters or additional licences.

Protective countermeasures are under development, including lens shutters and filters that block certain laser frequencies.Only a few countries can carry out dazzle attacks, but dozens of countries can jam satellite signals using ground-based transmitters to overwhelm their signals.
A new wireless standard called Dedicated Short Range Communication (DSRC)—a sort of Wi-Fi for cars provides high-speed data connections over distances of up to 200m, and safety and emergency communications at lower speeds over distances of up to a kilometre from one vehicle to another, and between vehicles and roadside transmitters.
As a white-space gizmo moves around a city, the channels it can use will change, depending on how close it gets to various transmitters.
