The VoLTE edge: mission-critical voice over LTE

In the last five years, and carried by the enormous success of smartphone and tablet devices in providing a user-friendly interface to mobile user equipment, Long Term Evolution (LTE) has matured from one of several possible radio data transmission broadband technologies to quickly become a de facto standard radio layer for all future mobile applications in the mobile telecommunications sector. Although traditionally very conservative in terms of technological innovation, the rail industry is coming to terms with this state of affairs. As ubiquity and data collection become firmly established as a possibility in the expectations of railway stakeholders, the demand of services that require broadband radio connectivity is increasing. The industry is starting to respond to this increase in demand in the rail sector, as well as in other sectors such as First Responders and Emergency Services. This paper will explore how LTE is changing to meet this demand, with particular emphasis on the provision of mission-critical voice services over a LTE radio layer, and what will be the implications of those changes on the railway industry at large.
