With the new IS440.2, i.safe MOBILE is launching a modern radio device for ATEX Zone 2/22. It combines the functionality of classic push-to-talk devices with current 5G, Wi-Fi, and Android technology – ideal for safe use in explosion-prone industrial environments.
But how does the IS440.2 differ from established devices such as the Motorola R7 Ex, which is also built for professional use in difficult conditions?
🔍 What is the IS440.2?
The IS440.2 is a robust Android radio with ATEX certification for Zone 2/22. It has been specially developed for modern communication solutions based on mobile phone or WLAN infrastructure.
Important functions:
- Push-to-Talk-over-Cellular (PoC) via 4G, 5G or Wi-Fi
- Android system with access to specialised apps (e.g. TASSTA, MDM, alarm system)
- Large physical buttons for PTT, emergency call and group selection
- Removable battery, robust design, industrial suitability
- App World as a platform for company-specific communication tools

🔍 What can the Motorola R7 Ex do?
The Motorola R7 Ex is a classic DMR radio, also ATEX or IECEx certified (depending on the model). It is designed for users in fixed radio network infrastructures (e.g. factory premises, emergency services, industrial facilities).
Important functions:
- DMR radio with high voice quality
- Wi-Fi-enabled, e.g. for configuration updates, replication, location functions
- No Android interface, no app installation possible
- High robustness (MIL-STD 810, IP68), clearly focused on classic wireless solutions
- Integration into Motorola systems such as Capacity Max or WAVE PTX

✅ Fazit
The IS440.2 is designed for companies that want to implement modern communication with LTE/5G, WLAN and app integration in ATEX zones. Ideal for smart campus solutions, security services, maintenance teams or process monitoring.
The Motorola R7 Ex is the proven solution when classic DMR radio with a fixed infrastructure is required – for example, in safety-critical areas, government networks or for large factory premises with their own radio network.
📲 Our tip:
Before purchasing, it should be clear whether classic radio infrastructure (DMR) is available or whether PoC-based communication via mobile communications or Wi-Fi is planned. The devices serve two different scenarios – and there is no "better" option, only "suitable".
