In this white paper, we show how improved coverage is creating new opportunities for push-to-talk over cellular technology. We predict it is just a matter of time before the first blue light service makes the switch to PTToC and others follow.
Around 95 per cent of the world’s population now has access to a mobile broadband network, according to the International Telecommunication Union. Between 2015 and 2022, 4G network coverage doubled to reach 88 per cent of the population. For most developing countries, mobile broadband – using 3G and above – is the main means of connecting to the internet, said the ITO, an agency of the United Nations.
The UN has called for nations to “build resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation”. Progress towards the sustainable development goal will help deliver peace and prosperity for people and the planet. And it will bring in a new era for critical communications.
Despite difficulties in closing the coverage gap for the five per cent of the global population who remain off the grid, most people can access mobile networks, whether 2G, 3G, 4G or 5G, wherever they are in the world.
The infrastructure is in place, which creates opportunities for industrialisation and innovation. In the critical communications market, the growth in mobile network coverage has exposed the limitations of legacy radios and opened up new opportunities for push-to-talk over cellular (PTToC) technology to support sustainable development.
