MiMOMax PMR/LMR linking

A common misconception among radio professionals is that when linking analog and digital PMR base station sites, generally a large bandwidth is needed. However this is not always the case.

The fact is that ‘megahertz bandwidths’ are not always needed to provide a reliable low-latency PMR network linking solution capable of supporting a large number of PMR radio channels. Instead, there is a growing recognition that ultra-spectrally efficient narrowband systems that have been cleverly designed to efficiently manage voice traffic are a good fit for linking PMR sites. Systems selected on the basis of ‘megahertz bandwidths’ alone may still lead to excess voice delays and packet loss.

The MiMOMax highly intelligent radio uses multiple input, multiple output, space-time diversity, in combination with high orders of modulation and M-DAP (data acceleration protocol) with radio-optimised compression algorithms and robust traffic management to provide very high capacity in narrow bandwidths. With this technology it is possible to support a large number of PMR channels in narrow bandwidth with minimal packet loss and late packet arrival, while maintaining very low latency and jitter across challenging terrains.

Forward error correction and fast training algorithms are used to enhance reliability and ensure high availability even in fading conditions.
