Could 5G mean the difference between life and death? periodically invites third parties to share their views on the industry’s most pressing issues. In this piece Rohit Gupta, Head of Manufacturing, Logistics, Energy & Utilities, Europe at Cognizant, looks at the effect 5G will have on the effectiveness of emergency services.

The rollout of 5G has been met with an element of scepticism. There are questions around whether the technology will deliver on expectations, concerns around security for both businesses and consumers and, although not proven, worries about potential health risks. Whatever reservations people may have, the fifth generation of cellular technology is upon us, bringing with it an abundance of opportunity for businesses to capitalise on increased data speed and potential new revenue-generating models as well as benefits for society at large.

5G is also set to transform a sector that we all rely on as a matter of life or death: our emergency services. Here are some of 5G’s benefits and opportunities for the emergency services industry over the coming years.

Inside the control room

5G reduces latency to one millisecond, speeding up emergency response times. The quicker the data is shared, the faster a response can be triggered, which could massively increase the speed at which critical health information might be shared. A trial by Air Ambulance Kent Surrey Sussex and South East Coast Ambulance Service NHS Foundation Trust has already used a video-capable mobile phone to stream videos from the emergency scene in real time. The study found that video streaming can reduce the stress of the person reporting the accident, as those at the scene were able to pass information on to the ambulance service more accurately.

The introduction of 5G means we will have access to faster speed, shorter delays in data transmission, and increased connectivity through greater capacity in the towers. Using 5G, video streaming can stream uninterrupted with less latency, bringing operators closer to the front line and ultimately leading to more lives being saved.

Such on-site capabilities also make it possible for emergency service operators to assess the severity of a situation and determine the best course of action. In the future, we could see this technology used to give remote guidance on how to treat people at the scene of an accident.

5G will enable the large-scale adoption of the Internet of Things (IoT), bringing together critical data and smart traffic systems. Equipping emergency vehicles with 5G SIM-fitted telematics systems will mean the data about their locations, road conditions, and traffic situations can be transmitted to the control room. The operators can then triangulate this information with the data they are getting from smart roads, smart traffic lights, and weather conditions to determine the best possible route to reach the patient in need or to the appropriate hospital.

Taking to the skies

Emergency services in the UK are already experimenting with emerging technologies. It was recently reported that new proposals could see the NHS use drones to transport blood and chemotherapy kits between hospitals and GP surgeries.

Not only do these developments improve the efficiency of services, they also protect employees. Drone aerial imagery can help firefighters obtain information about the exact location of an accident in a building, help pinpoint an individual’s location, or assist with searches at sea.

In order to ensure the right course of action is taken and lives are saved, high quality footage is vital. Verizon states that 5G’s millisecond latency and data speeds are up to 100 times faster than 4G, allowing drones to transmit high-definition, real time footage. This imagery can then be shared with operators helping staff work towards their goal of saving lives without compromising their safety.

A smart approach to on-the-road care

5G should improve digital connectivity including communication between emergency vehicles and their surroundings, helping track emergency vehicles and support smart traffic systems to give ambulances and other vehicles priority on the road.

With vehicle telematics systems transmitting data to the control centre, healthcare professionals in the centre can monitor the patient’s condition through the video, providing care suggestions as well as helping first responders to make on-the-spot decisions. Location details and estimated time of arrival will help hospitals prepare for receiving the patient and preparing the necessary teams. IoT-enabled medical devices can transmit data and test results to the control centre, hospital, and healthcare professionals, thereby reducing patient handover timings at the care centre.

5G is a new technology, and using it is not simply a technology challenge. 5G offers the potential to not just do business as usual and quicker, but also to do it differently. As adoption of 5G increases and more and more devices become IoT-enabled, the possibilities in a near-zero latency world will be endless. Designing new processes that take advantage of new possibilities for the good of society is the work ahead of us all.

New opportunities await operators willing to invest in critical networks periodically invites third parties to share their views on the industry’s most pressing issues. In this piece Tero Pesonen, Chair, TCCA Critical Communications Broadband Working Group (CCBG) offers an overview of the crit comms market.

For consumers, mobile networks need to be reliable. Yet if quality of service is an issue, users usually look to switch their service provider. For users for whom communications are critical – as in the difference between life and death – the networks as well as the services they provide need to be exemplary.

Users of critical communications services are termed either mission critical, business critical, or both. Mission critical organisations are, for example, police forces, fire and rescue and emergency medical services, generically referred to as Public Protection and Disaster Relief (PPDR). Examples of business critical user sectors include public utilities, oil & gas and transportation organisations, but there are many more areas where critical communications are essential.

Within the mission critical segment the key driver is the safety and security of civil society. In the business critical segment the focus is typically on continuity of service of critical infrastructure, and significant environmental protection and economic values are usually at stake. In both segments, operational efficiency and effectiveness are also important considerations.

To date, critical communications services have been based on dedicated designed-for-purpose technologies, dedicated networks and dedicated spectrum. The service operators are typically government-controlled, serving only mission critical organisations such as PPDR and related agencies, and business critical users if legislation allows.  These highly-specified digital technologies include TETRA, Tetrapol, P25 and DMR, and legacy analogue technologies are also still widely used. However, these are all narrowband, and their capabilities for data applications are limited.

Technological and ecosystem evolution is changing the critical communications landscape, and opening up new business opportunities to commercial network operators.  The next generation of critical communications solutions will be based on 4G/5G technologies and open standards defined by 3GPP. The model of using dedicated networks is being challenged and commercial networks represent a new option for the provision of critical communications services.

The lack of dedicated frequency bands for broadband critical communications also makes commercial operators favourable partners for delivering critical broadband services.  Spectrum is a scarce resource and the trend, at least in Europe, is to auction spectrum to the commercial sector, although some countries will grant some dedicated spectrum for broadband critical communications. Hence it seems that sharing with consumers may be the best way to find an economically feasible solution for broadband critical communications users.

There are already significant next generation critical communications projects ongoing in which commercial operators are playing a central role. Examples include the Emergency Services Network in the UK, FirstNet in the US, SafeNet in South Korea, and in The Netherlands for railways.

Existing commercial networks can be utilised for the provision of mission critical and business critical services, provided crucial requirements around coverage, quality of service, availability, reliability, functionality and security are met. Mission critical services are needed on a nationwide basis – a major event can occur anywhere. Wildfires, plane crashes and terrorist attacks do not confine themselves to areas that have a good mobile signal – hence comprehensive radio coverage is a prerequisite for mission critical users.

In most countries, for nationwide service achieving 99+% coverage requires the extension of existing commercial networks. In addition, mission critical users expect 100% service continuity during major incidents, extreme weather conditions or other crisis scenarios. Higher levels of data security and protection against malicious attacks are also required. Altogether, this means that ‘hardening’ of the commercial networks is necessary. An obvious upside for the operator is that by upgrading the network to serve critical users, it becomes a differentiator; more attractive for commercial users.

Business critical users often look for solutions that balance performance and price and hence their requirements can be less stringent, although within this sector there are very demanding users. Railways for example are likely to have very strict requirements when they seek to include train control functions. In addition, business critical coverage requirements are typically more concentrated depending on the location – for example, to serve an airport, only local coverage is necessary.

There are many projects either already ongoing, or planned, in which established PPDR service operators are looking to complement their narrowband services with mobile broadband offerings. Often, especially in Europe, the preferred option is to seek collaboration with commercial operators, which opens a natural avenue for the commercial sector to enter the critical communications service market. PPDR service operators have the knowledge of critical users’ needs, manage the customer interface and operate within the necessary contractual framework ensuring compliance with operational and legislative requirements. The commercial operators bring economies of scale and knowledge of 4G/5G technology deployment.

This is a huge opportunity and requires a major change in thinking compared to the existing operators’ businesses, which is clearly dominated by services to consumers. One of the operators’ future options is to combine several new services to create added value for new customer segments. Critical communications could be complemented with resilient Internet of Things (IoT), smart city and smart building services, etc. – thereby increasing operators’ business potential.

There is plenty of work going on behind the scenes to ensure that critical users have the adequate level of service from 4G networks to perform their tasks efficiently and safely. It is likely that the requirements for critical data services will be fulfilled first, whilst critical voice services in large scale will stay on the purpose-designed nationwide networks in parallel for quite some time. Standardisation of critical features is ongoing in 3GPP, and there is much testing and certification of infrastructure and devices to be undertaken before a network based on 4G can be classed as truly mission critical. But opportunities are emerging, and commercial operators need to build their knowledge and become active to step by step to realise the potential.

AT&T secures FirstNet win after nationwide thumbs up

AT&T’s plan to design and build a dedicated nationwide public safety broadband network has received the green light as all 50 states, two territories and Washington DC say yes.

The network itself was proposed as a way to combat the communications challenges that first responders had to contend with following the terrorist incident on September 11 2001, and the days following. While generally accepted as a good idea, there was a risk of support falling short as certain states pokes holes in the plan. The FirstNet opt-in/opt-out period ending just before the New Year, granting the green light.

“Our FirstNet offering will forever change the way first responders communicate,” said Chris Sambar, SVP for FirstNet at AT&T.

“Securing 53 opt-ins is significant for the public safety personnel that this network will serve. And we’re honoured to give first responders across the country quick access to this life-saving solution.”

While there are many advantages to the network, perhaps the biggest is prioritization. First Responders will have immediate and priority access to AT&T’s LTE communications network, should there be an incident anywhere in the country.

Now that the opt-in/opt-out consultation has been completed, AT&T expects the official go-ahead from the US Government in early 2018, with construction to kick off almost immediately afterwards. AT&T has pledged $40 billion to the construction of the network, with potential to open the plan up to other US territories in the future.

“FirstNet is the network for public safety,” said Sambar. “2017 was about planning, preparing and moving quickly to bring public safety a meaningful option – one they can rely on without delay. We’ll build on that groundwork in 2018 with transformative capabilities that will make FirstNet the most valuable communications system for first responders.”
