Samsung's got strong LTE (and LTE-A, and... whatever's next) bones and now it's looking to shift the commercial tech into the emergency services. Public safety announcements has been a project of the 3GPP for a while. What's that, you say? It's a ragtag gang of
superheroes telecoms groups and organizations that hammers out the crucially important (but typically very dry) standards and technical specifications -- these have formed the basis for the likes of 3G and LTE in the past. Samsung's public safety LTE (PS-LTE) is apparently geared for first responders and use during "emergency situations". Importantly the option of a new kind of public safety announcement network will take the drag off existing networks, as well as offer the data heft of LTE network, hopefully ensuring communication remains possible in even the most dire situations.
