Push-to-talk with guaranteed 4G network access: Flash SmartCom
Flash SmartCom is a secured push-to-talk service for smart devices, offering guaranteed availability and priority on Odido's (formerly T-Mobile) 4G network. At the touch of a button, you can reach every employee — wherever they are. Combined with our additional services and (emergency) applications, Flash SmartCom is both a reliable and flexible solution for business- and mission-critical communication.

End-to-end push-to-talk solution
Flash SmartCom is an end-to-end push-to-talk solution. It doesn’t just include robust (ATEX) devices with accessories and a SIM card with both network priority and guaranteed availability — customers can also add extra applications and services, such as LoneWorker Protect, Flash SmartAlert, and our control-room application, plus a mobile device management environment.
What is push-to-talk?
Push-to-talk (PTT) is a way of communicating by voice, best known from two-way radios and mobile radios. The principle is simple: press the button and send a message straight to a person or group. Push-to-talk over cellular (PoC) uses the 4G and 5G network. Compared with traditional PTT, PoC offers key advantages such as nationwide coverage, an unlimited number of voice and video call groups, and the ability to send photos and text messages. Whatever the form, the idea behind PTT is always the same: everyone stays informed of the current situation and can act on the same information.
Flash SmartCom functionalities
Flash SmartCom’s push-to-talk application offers the following functionalities:
- One-touch communication
- Unlimited number of call groups
- Sending and receiving images and (data) messages
- GPS positioning (e.g. for immediate on-site assistance)
- Emergency button for emergency calls
SmartCom also lets you make voice recordings, place calls to the control room, enable real-time video, and retrieve map information.
The result?
Guaranteed communication — especially in critical situations — so employees can work safely 24/7. Flash SmartCom also means maximum flexibility and complete peace of mind.
Wherever critical communication is required
Flash SmartCom fits a wide range of situations, which fall roughly into three categories:

Business Critical Communication
Mission Critical Communication
Communication in a large geographical area
Business-critical communications
We speak of business-critical communication when it is essential to the business process and a communication failure could cause damage. Examples include security, emergency response teams, water boards, city wardens, large event organizations and public utilities.
Mission-critical communications
Mission-critical communication means communication is essential to people’s safety: a failure could have fatal consequences. In this area, our solution is often used within transport and logistics, industry, (petro)chemicals, and public order and safety. Customers frequently combine it with mobile device management software to secure mobile devices, and integrate it with the control-room application for alarm follow-up.
Communication within a large geographical area
Finally, some customers use Flash SmartCom for communication across an area so large that local resources alone are no longer sufficient.
Situations where Flash SmartCom is the answer
In the following situations, Flash SmartCom is an ideal communication solution:
- Reach all employees inside and outside the company at the touch of a button.
- Managing drivers nationwide.
- Short-term events where direct communication is needed for security.
- Providing regionally working home care workers with a smartphone app that allows them to communicate with a single tap.
- Field service workers who can communicate and alert in remote areas at the touch of a button.
The three key benefits of our PTT solution
1. Security: always a good connection
With Flash SmartCom, you have guaranteed network access with priority on Odido’s network, which is the best network in the Netherlands in most independent tests. The network priority ensures flawless communication, even when the network is busy, for example.
Almost 100 percent availability
Thanks in part to the large number of sites (>5000), the Odido network has national coverage of nearly 100 percent, a large data capacity and both high availability and speed. Because the network has multiple overlapping base stations, if one base station fails, coverage is taken over by another. In addition, T-Mobile has a backup power supply of at least three hours per site. Result? Nearly 100 percent availability of (data) connections.
Advantages over traditional walkie-talkies
Mission-critical push-to-talk has significant advantages over traditional walkie-talk: you can use many more (data-based) functionalities and you do not have to deal with geographical limitations.
User levels
We also offer security through user levels, which can be defined and managed at the customer level. An emergency room operator, for example, has a higher user level so that he can override ongoing calls to ensure that messages always get through.
Fallback: second provider
Do you want even more security? Then you can opt for our fallback service, which gives you a second network provider for maximum availability.
2. Flexibility: move with your needs
Flash SmartCom exudes flexibility in everything. For example, it is a complete service with no restrictions on the number of users or groups. As a system integrator, Flash Private Mobile Networks (Flash PMN) also provides a large number of services, which you can purchase modularly. For example, we can link existing systems, including walkie-talkie networks and paging and alarm systems, to our push-to-talk service.
3. Full service: from device to on-site support
As a complete service, Flash SmartCom includes mobile devices (including accessories) with push-to-talk application, SIM cards with priority, network connections and other applications if required. Flash PMN installs the applications as well as configures, manages and maintains the devices. Thanks to mobile device management, we can do a lot remotely, minimizing the management burden for you, the customer. We also offer customization and on-site support. Are you taking the plunge with us? Then you are not just taking on a service partner. On the contrary: we also like to think along – proactively or not – about the optimal implementation of all your communication wishes.

Applications
The main application within Flash SmartCom is the push-to-talk app, which is designed and built to industry standards. The solution can be expanded to include the following three applications:
LoneWorker Protect
The LoneWorker Protect mobile application provides protection for lone workers performing high-risk work. With the emergency button, immediate alarms can be triggered, with the position automatically transmitted to the monitoring center. Adjustable sensors allow you to set up automatic alarms, such as fall detection (“man down”) and inactivity. After an alert, both the alarm center and any colleagues are immediately notified so that quick action can be taken.
Flash SmartAlert
With the Flash SmartAlert app, employees can send notifications directly to the Flash SmartAlert dashboard from any location. And vice versa. Because it efficiently and effectively informs the right people about an incident, it is a suitable FAFS app. The application includes functionalities such as emergency calls with location indication, setting presence, a chat function, displaying procedures, and anywhere, anytime insight into alarms.
Control room application
The Control Room application is dispatcher software for PCs that allows you to remotely monitor and control all walkie-talkie users and groups from a central point. Functionalities such as dynamic groups, GPS location of users on the map and geographical sector classification guarantee effective emergency communication and ensure that you act quickly and effectively in the event of an emergency. The application also allows devices to be managed remotely.
Own applications
As a Flash SmartCom customer, you can also use your own applications on the devices. Examples include apps for event information, user instructions or mobile payments. Flash PMN facilitates maximum availability of the applications on the devices, including by (remotely) rolling out operating system updates.
Modular services
Not only Flash SmartCom, but the entire service spectrum of Flash PMN is modular. You decide what you purchase, and scaling up or down is always possible. Within Flash SmartCom you can choose from the following modules:
- The mobile applications LoneWorker Protect and Flash SmartAlert.
- The Control Room application for PCs
- Mobile device management, or a management environment for mobile devices
- Management reports
The following organizations are already successfully using SmartCom

FAFS app: Flash Smart Alert
Flash SmartAlert is a mobile application that ensures that your FAFS organization is quickly alerted to emergencies and can act appropriately. Alarms can be raised manually or automatically, for example through the fire alarm system. The alarm messages arrive as push messages to the emergency response workers. The alarm sounds at a fixed volume (ignoring the phone profile) and stops only after the user has read and dealt with the message. The central dashboard provides overview and facilitates tight direction during emergencies. Finally, geofence ensures automatic registration of FAFS officers.
Knowledge Platform Flash Forward
Even the very best equipment becomes worthless when used incorrectly. Things like not charging the battery properly, not turning on the walkie-talkie or not activating the man-down function can even lead to incidents (fatal or otherwise). This is why we have developed Flash Forward. With this platform, we want to transfer and exchange knowledge via informative content, workshops, user training, an electronic learning environment, internal training courses and our annual partner event, among other things.
