This article analyzes the capacity limitations of MCX voice services on broadband networks in terms of simultaneous streams per cell by identifying transmission and protocol bottlenecks.
The evolution of critical communications, from the former narrowband, mostly voice-only Private Mobile Radio (PMR) to today’s multimedia-enabled broadband Long Term Evolution (LTE)/Fifth Generation (5G), has changed the underlying network. has been adjusted by. Due to the nature of critical communications, the 3rd Generation Partnership Project (3GPP) has established a set of requirements and recommendations to ensure the availability and performance of mission critical services (MCX), especially for large group communications. We have defined the matters.
However, to date, no research has been conducted to determine whether commercial networks, or even hybrid LTE/5G networks, can actually meet the capacity and scalability conditions required during a crisis.
This paper, written by Adrian Santiago, Andoni Diaz De Cerio, Aitor Sanchoyerto, and Fidel Legal, comprehensively identifies the capacity limitations of MCX voice services on broadband networks in terms of the number of simultaneous streams that can be provided per cell. It is analyzed by. Bottlenecks related to various transmissions and protocols. Aggregating these constraints results in a theoretical model of maximum LTE/5G capacity that is much more realistic than coarse-grained estimates that consider peak rates across cells.
Additionally, a comparison between MCX over LTE and 5G is provided, showing the percentage of unusable or wasted radio resources relative to the total available. In this way, it provides not only the maximum capacity that can actually be achieved, but also a measure of efficiency regarding the use of radio resources. This is critical to the business model behind hybrid deployments.
Both results contribute to improved network dimensions and more fine-grained tuning of network and service parameters.
