A mission-critical smartphone must meet certain key requirements. These requirements cannot be met by a regular smartphone. But what are these key requirements? How do you choose a mission-critical smartphone? How do you manage smartphone risks for professional users? And how do you communicate when your mission-critical smartphone is out of coverage? This blog post answers these questions as well as many others about smartphones for professional users.
The term ‘mission-critical’ is used to describe a network, solution or application that must function reliably at all times. If the system does not work, there could be serious consequences. Mission-critical can be anything that is essential to survival.
To use broadband communications, public safety and other professionals first need to get mission-critical broadband connectivity.
If you think of broadband use as driving, the car is the smartphone and the access to broadband is the road. You need both before you can start driving.
In mission critical communication, information must be exchanged, or unfortunate things will happen. Professionals need their mission-critical communications to meet these three requirements:
What is the meaning of mission-critical smartphone?
A smart device will not be mission-critical if it uses ordinary consumer broadband. It must have access to mission-critical broadband.
The first thing a professional needs is group communications. This means that mission-critical smartphones need PMR-like features in an app, such as Tactilon Agnet. A basic, mission-critical smart device will have mission-critical push-to-talk, push-to-data and push-to-video.
But, just putting a push-to-talk app on any smartphone does not make it mission critical. The app and smartphone must be able to work together. The smartphone must also be secure in all areas. These include hardware, bootloader, application containers, deployment and management. The devices must also be rugged.
Mission-critical smartphones must also receive updates to their operating system and security for many years.
Professionals expect their smart devices to have a longer lifetime and a longer operating time than consumer devices. There are eight great ways to make your device run for longer between recharges. You can see some of these in the blog post "Eight tips to extend the battery life for your duty smartphone".
A mission-critical smartphone must be easy to use throughout a working shift. When a mission-critical smartphone is used for MCPTT communications, it needs six features:
Most public safety professionals still carry a traditional professional radio. It has been designed for a purpose. A mission-critical smartphone must also be fit for purpose. The device must work well with its accessories and gadgets.
For example, a smartphone should support professional-grade earpieces that are comfortable and stay in place. A wireless earpiece can be useful in the field.
How and where will you carry the phone? Wearable holders, belt clips and special pockets can be used on the move.
Learn more about professional accessories – read the blog post “Why professional smartphones need secure, special gadgets”. Or watch the video “How to use your smartphone as you would use your radio”. These show how to use a smartphone in a noisy environment, in an explosion-prone area and in an undercover operation.
Your TETRA or Tetrapol radio has been your most important tool for years. And on duty or off, you may also have your smartphone with you at all times. So, which public safety smartphone should you buy? Here are 8 quick tips to choosing a mission critical smartphone.
Think carefully about the best rugged smartphone for your needs and look at all the features.
Make sure you can use a mission-critical communication solution (MCS/MCX), such as Tactilon Agnet. Without it, your smartphone will not be suitable for professional use. You would not trade in your radio for a smartphone if you did not get anything extra.

How would professional smartphones work in real life? How would a police officer use them to make their work easier?
Let’s imagine a police officer called John from a town called Securicity. During the first half hour of his working day, he might benefit from the following eight advanced features.
John’s morning routine begins at home and includes a large mug of coffee and reading the latest news on his phone. He can start his shift even before he finishes his drink.
The imaginary police officer John has used eight advanced features in the first half hour of his day. We can only guess at how these and other features will help him meet the challenges of the rest of his day.
Samsung offers rugged smartphones, complete with task management and collaboration applications. The portfolio also includes military-grade rugged smartphones.
In addition, Knox is the defence-grade mobile security platform from Samsung. It protects the device with multiple layers of data security. It provides comprehensive security and device management protocols in the hardware, operating system (OS) and application layers. This guards against malware and data breaches and even protects lost or stolen devices.
Samsung is an important partner to Airbus in smart devices.
Tactilon Dabat looks like a regular fully rugged smartphone. However, it is a mission critical smartphone and a TETRA radio in one device. It is designed for professionals who need to stay connected. They can rely on three networks: the TETRA network and a choice of private or public LTE network, with unique Smart and Hybrid Roaming features. The device will also know which broadband network to use. If the network is not available, Tactilon Dabat can connect directly to another device in Direct Mode Operation (DMO).
Tactilon Dabat is also ergonomic and easy to use. A smart dashboard holder called Ergo Plugin keeps users connected when moving in and out of the vehicle. Get the details on Ergo Plugin for Tactilon Dabat – download the datasheet. Or watch the video “How can you stay super connected between TETRA and broadband while on the move?”
Tactilon Dabat also has the familiar multi-purpose push-to-talk buttons used on Airbus TETRA radios.
Zebra public safety smartphones and tablets meet the demanding needs of first responders. There are rugged models that are waterproof, drop-proof, dust-proof and tumble-proof. They also have a Gorilla Glass touch panel and imager window that resists scratches and breaking.
In addition, Zebra devices include dedicated buttons such as push-to-talk (PTT) and ‘most used function keys’ features, while the battery can also be changed easily during the shift. The devices have a long lifespan and also have their OSs upgraded to take advantage of similar features to those on traditional PMR radios. Zebra’s name is derived from the stripes making up barcodes, underlining its wide experience of data management apps.

Are smartphones secure?
Most consumer smartphones – even rugged ones – can be attacked by people trying to steal data. Other types of attack are aimed at software vulnerabilities in the browser, email, or operating system.
Because of these risks, using a smartphone can cause problems for professional organizations that need mission critical communications. Guarding against these risks means balancing high security and ease of use.
To keep your communications private, you need to look at conversation security. It is similar to information security and covers more than technology and features. Secure conversations and secure information depend on people and processes. You need to control access and identity, and also protect and monitor things. You also need a log to keep track of untoward events. This will allow you to investigate and resolve situations. Security breaches are embarrassing and expensive. Your communications solution must detect and respond to threats quickly and efficiently.
Regular smartphones are open and do not provide enough control over risks. Tactilon Dabat employs several methods to control risks. It is not open and so achieves optimal security for mission-critical users.

A smartphone is mission-critical only when it runs on a mission-critical network. The network must be available, reliable and robust. It must continue to provide service when other systems fail or when parts of the infrastructure are off air or damaged.
TETRA users rely on their radios anywhere within the network area, and at any time. Where there is no network coverage, they can still communicate by sending signals between radios. This is called Direct Mode Operation (DMO).
Commercial mobile networks do not support Direct Mode yet. Even if they did, smart devices have limited output power. This means that device-to-device operation cannot reach very far. The range would be meters rather than kilometers like in TETRA.
There is one smart device that can work in Direct Mode – Tactilon Dabat. It can provide the most powerful solution for device-to-device communication.
The Quality of Service (QoS) of a mission-critical network measures its ability to achieve maximum bandwidth while also providing high performance. QoS also involves controlling and managing network resources. This is done by setting priorities for specific types of data (video, audio, files) and for specific types of users (mission-critical and others) on the network.
Knowing the availability of communication services in a commercial broadband network requires an end-to-end view of the service.
This information may not be available if the network elements are controlled by Mobile Network Operators (MNOs).
This overview can be gained by gathering information from smartphones and other smart devices. This is known as service analytics.
In practice, a special client will be set up in the mobile user devices, e.g. smartphones and other smart devices. The clients follow the levels of service that the devices (and thus the users) experience. Their reports are consolidated, and the results can be visualized. This shows accurately where the service is good and where it can be improved.
