"MiMOMax has recently released a White Paper addressing the common misconception that large bandwidths are needed when linking analogue and digital PMR sites. This article then goes on to elaborate how intelligent narrowband radio systems can be efficiently employed to link digital PMR sites and other high bandwidth applications with very low latency, jitter and high availability in challenging terrains"

From the white paper:
According to MiMOMax, “megahertz bandwidths” are not needed to provide an optimised low-latency PMR network-linking solution. Instead, there is a growing recognition of the value that ultra-spectrally efficient narrowband systems that have been cleverly designed to achieve the desired QoS (quality of service) — are a good fit for linking PMR sites. In fact, if the QoS issues are overlooked, then the systems selected on the basis of “megahertz bandwidths” alone may still lead to excess delays and data loss.

At the same time, the increasing popularity of IP has shifted the paradigm from “IP over everything” to “everything over IP, including linking of PMR sites”. Behind all this success is the underlying fabric of the internet: the Internet Protocol. IP was designed to provide best-effort service for delivery of data packets and to run across virtually any network transmission media and system platform. As a consequence, issues such as delay (latency), variation in delay (jitter), packet loss, late packet arrival, availability and bandwidth requirements all become very significant.
