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.

Abstract: A method and apparatus for providing direct access to one or more sensors from an internet protocol network. One example method includes detecting, by the remote terminal unit, a first sensor coupled to a first communications port. The method also includes generating a first unique internet protocol address for the first sensor, and mapping the first unique internet protocol address, at an application layer of a network protocol stack, to the first sensor. The method includes broadcasting, over the internet protocol network at a network layer, the first unique internet protocol address and an identity of the first sensor with which the first unique internet protocol address is associated. The method includes monitoring, at the network layer of the internet protocol network, for a sensor message identifying the first unique internet protocol address as a destination address, and forwarding the sensor message to the application layer for further processing.

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.
