The Holy Grail of a cheap, ubiquitous and hyper-reliable, high-speed network that serves the needs of both public safety and commercial communications may not yet be achievable.
Significant advances in standards and technology are bringing ever closer the benefits of commercial scale and high bandwidth while preserving the desirable features of existing public safety networks.
This paper, originally intended for internal use, draws on publicly available information sources to chart the progress in standards, technologies and the initial trial deployments that pave the way for the future.
