Every day, across the globe, emergency services teams come to people’s aid no matter the situation to ensure their safety. Whether it’s during a natural disaster, or at a significant event, the emergency services are on hand to face any challenge that comes their way. When supporting this crucial workforce, it is essential that they have robust and reliable connectivity.

Technology is becoming a vital aspect of public safety and security worldwide, and this trend is only likely to grow. For these new devices to work effectively, full-scale coverage must be in place, and when it comes to people’s safety, there is no room for error.

The need for redundancy and high bandwidth 

Two of the paramount tools at emergency services disposal are video surveillance and communication devices. Constant visibility and communication are often essential to protecting people and saving lives. The benefits range from providing first responders with a clear picture and understanding of the situation they are about to encounter; to providing greater safety during public events by enabling officers to control crowds and manage traffic effectively. Enhancing visibility and sharing information is particularly crucial during fires to guide firefighters and vehicles through flames and smoke, and to allow the central command center to organize resources effectively.

Despite any potential challenges ensuring network connectivity may create, public safety organizations cannot compromise when it comes to optimizing security. For IP video surveillance and cellphone broadband connectivity to operate effectively, they require redundancy and high bandwidth. Without these connectivity attributes, devices become useless; for example, there are municipalities where as much as 50 percent of the camera network is offline because of poor product choices and inferior network design and installation. Equally, poor quality networking can be just as limiting as it can lead to public safety organizations being unable to receive real-time data. All areas must also have adequate bandwidth to access data, such as on-scene video, aerial imagery, maps, and images, and many existing public safety networks do not have that capacity.

Supporting security and safety robotics

Robots and drones have seen a considerable increase in popularity this year, with 60 million such machines being deployed according to ABI Research. They offer a wealth of potential to emergency services teams, whether on land, air, or sea. For example, water rescue robots can go where humans cannot, earthquake and fire robots can search through otherwise non-navigable areas, and drones can survey vast regions.

However, for these wireless devices to work effectively, they rely on many features. They need low power consumption so as not to heavily burden the onboard power source of the robotic device and, perhaps, a high level of encryption so information cannot be stolen or hacked. There are also benefits to security and safety as robotic devices can communicate with one another peer-to-peer. Directly mounting radios to robots and drones, fosters dynamic self-learning, data sharing, and more wireless paths in the event one or more of the devices in an area do not have a link to fixed infrastructure.

The main component that security and safety robotics require is redundant and resilient connections. If the connection is lost, the connected device will go into “safe” mode and stop. Creating a high capacity network that supports mobile devices in complex and fast-moving environments is not a simple task. In many cases, it requires a network that supports many wireless connections and allows for many paths in and out, so that if a link is lost, another path is available for data transmission and reception. This type of network is the best way to ensure that police, firefighters, and emergency units can access and send large amounts of data from wherever they are and in real-time making a massive difference to the efficiency of the emergency services.

An example of this is Rajant’s private Kinetic Mesh® network, a wireless network ensuring no single point of failure. It offers reliable, intelligent, and secure wireless broadband connectivity that survives and thrives in evolving and mobility-driven environments. It forms a “living” mesh network that can move with and adapt to the evolving communication requirements of public safety organizations.

Technology in action

Back in October 2019, the heat from the sun, combined with winds gusting through the foothills of El Capitán Canyon in California, sparked a bush fire in the overly dry, desert hills. Despite four hundred and twenty acres being burnt, firefighters used their experience and skills combined with newfound digital technology to ensure that no structures were damaged, and there were no reported injuries.

The Santa Barbara County Fire Department, Cal Fire, the U.S Forest Service, and other agencies were immediately dispatched to contain the fire. More than 200 firefighters were needed to combat the fire and reinforce containment lines with helicopters and drones in the air and bulldozers on the ground. To operate this equipment, mesh radio nodes, bonded cellular, and satellite technologies were used to link the communication gap in locations where signals are often dropped. Rajant BreadCrumb® nodes were mounted to the fire-breaking, 30-ton bulldozers manned by trained firefighters to uproot vegetation and eliminate the materials that would further spread the fire.

Robots and drones have seen a considerable increase in popularity this year, with 60 million such machines being deployed 

The reliable connectivity allowed the bulldozers to not only easily communicate with each other and the base, but also to send video footage and data to the tactical truck and central command post over cellular and SAT networks. This situational awareness data transfer allowed for greater efficiency, as well as increased safety for the public and the firefighters.

Reliability when you need it most

Reliable connectivity solutions are being embraced across the emergency services due to the innumerable benefits they bring to ensuring the safety of the public. For police, firefighters, and emergency units, dependable connectivity allows for rapid, real-time response, and the use of technology can save lives in ways that wouldn’t have seemed possible a decade ago. Planned and unplanned events can benefit from the new technology being introduced, and emergency services need to make sure they have the network capabilities to support them. For environments that are challenging and hostile, this requires a network available on-demand, which can withstand the demands of harsh conditions and mobility while maintaining a level of redundancy and high bandwidth that allows for accessing and sending large amounts of data from any location.
