Systems and methods for ambient noise mitigation as a network service
Systems and methods for ambient noise mitigation as a network service are provided. In some embodiments, an ambient noise mitigation server establishes at least one low latency network slice for at least one UE coupled to a radio access network. The ambient noise mitigation server generates a cancelation signal based on ambient sound mitigation data received by the radio access network, the ambient sound mitigation data including acoustic sensor data representing an ambient sound signal. The cancelation signal is generated to comprise a phase shift with respect to the ambient sound signal computed at least in part as a function of a location of the at least one UE, and causes at least one acoustic emitter to emit an acoustic cancelation signal based on the cancelation signal. In some embodiments, the phase shift may be adjusted by controlling a latency characteristic of the low latency network slice.
