What capability did the standardization around Bluetooth provide for global consumer adoption?

Answer

Reliable connection between different manufacturers' devices

The widespread success of wireless speakers in the consumer market was fundamentally dependent on the standardization established by Bluetooth, built upon prior concepts like spread spectrum communication. This standardization meant that the system was interoperable across brands. A user could purchase a mobile phone from Company B and reliably connect it to a speaker manufactured by Company A, regardless of the country of origin. This level of universal, convenient pairing was nearly impossible to achieve with earlier wireless audio solutions that relied on proprietary transmitter/receiver pairs.
