Surviving the digital transition: Maintaining UHF microphone systems for the future

A direct sequence spread spectrum implementation was developed in an effort to extend the operational lifetime of legacy analog wireless audio equipment. These legacy devices have an uncertain future due to spectrum reallocation and repurposing in the United States. Through the development of a drop-in module incorporating spread spectrum techniques, aging analog equipment can benefit from audio integrity preservation and isolation from other devices and services operating on the UHF band. By extending the operational lifetime of existing wireless equipment, this approach could reduce electronic waste.
