Abstract: Techniques for voice announcements over communications paths in siren systems are provided. In one aspect, a siren activation sequence including an audio identification sequence may be received at a siren alert site controller over a data communications channel of a first communications path. The audio identification sequence may be extracted from the siren activation sequence. A first combined audio signal may be received at the siren alert site controller over a voice communications channel of the first communication path. It may be determined that the first combined audio signal includes the audio identification sequence. The audio identification sequence may be extracted from the first combined audio signal to create a first audio signal. The first audio signal may be played over a siren controlled by the siren alert site controller.

Abstract: In one aspect, a method for enabling wired sensors to be coupled to a Low Power Wide Area Network (LPWAN) is provided. A first wired device that is coupled to the LPWAN gateway device via a first wired medium may be identified at a LPWAN gateway device. A first virtual node may be instantiated at the LPWAN gateway device, the first virtual node assigned to provide protocol conversion between the LPWAN and the first wired device. A request to join the LPWAN as a node that does not require Radio Frequency (RF) management may be transmitted from the first virtual node at the LPWAN gateway.
