The i.safe MOBILE IS380.1 is an intrinsically safe 4G cellular radio engineered for critical voice communication and worker safety in Australian explosive gas, vapour, and dust environments. Certified for ATEX and IECEx Zone 1/21 hazardous zones, it combines the straightforward usability of a traditional two-way radio with the wide-area coverage of modern cellular networks.
Designed to replace costly standalone RF radio repeaters with Push-to-Talk over Cellular (PoC), the device enables clear team coordination, lone worker monitoring, and automated emergency escalation across refineries, processing plants, chemical facilities, and bulk fuel storage terminals. Staged, configured, and supported nationwide by Roaming Technologies, the IS380.1 provides hazardous-area operations with a compliant, dependable communication terminal backed by direct enterprise support.

Performance and Processing Power
The IS380.1 is powered by a Qualcomm Snapdragon 662 octa-core processor operating on ISM-OS 16, providing dedicated computing power for mission-critical voice encoding and background safety monitoring. The device is configured with 8GB of system RAM and 64GB of internal storage, ensuring responsive application execution for Push-to-Talk (PoC) clients, electronic inspection logs, and emergency lone-worker protection (LWP) software.
Display and Input Design
This Intrinsically Safe radio features a 2.4-inch display (240 x 320 pixels) protected by scratch-resistant 3rd generation Corning® Gorilla® Glass. Designed for practical one-handed operation in the field, the unit combines a rugged numeric keypad with tactile navigation controls that can be operated while wearing heavy industrial gloves. A prominent red emergency SOS key at the top can be assigned to automated Lone Worker Protection (LWP) protocols, while dedicated large side buttons provide instant Push-to-Talk (PTT) voice dispatch.
Connectivity and Expansion
Engineered for reliable communications across Australia, the cellular modem covers 4G LTE-FDD frequencies, including Band 28A and Band 28B (700 MHz) for wide-area coverage in regional areas, alongside 4G LTE-TDD, 3G WCDMA, and quad-band 2G GSM. SIM connectivity supports dual operation via one physical nano-SIM slot and an integrated eSIM. On-site wireless networking features dual-band Wi-Fi (2.4 GHz and 5.0 GHz; 802.11 a/b/g/n/ac/e/k/r/h) with fast roaming protocols to maintain active call links between facility access points. Peripheral pairing uses Bluetooth 5.1 and Near Field Communication (NFC). Precision geolocation utilizes multi-constellation satellite tracking supporting GPS, A-GPS, GLONASS, BeiDou, and Galileo. Physical expansion interfaces include an industrial 13-pin ISM side port for screw-fastened wired accessories and a sealed USB-C port for desktop charging and data sync.
Battery Life and Charging
This fully rugged device is powered by a high-capacity 3,600 mAh Lithium-ion battery pack engineered to sustain continuous Push-to-Talk communication and background sensor monitoring across full 12-hour operational shifts. The battery is user-replaceable using the supplied secure screwdriver, allowing maintenance teams to swap cells in non-hazardous depot environments without taking the terminal out of service. Charging is supported via the direct USB-C port or through drop-in desktop and multi-bay depot charging cradles.
Usability
Measuring 138.0 x 60.0 x 32.0 mm and weighing 359 g, the i.safe MOBILE IS380.1 provides a balanced, compact radio form factor engineered for one-handed belt or chest-harness carry. It is purpose-built for the following enterprise workflows:
-
Hazardous Facility Communications: Maintain continuous team and dispatch radio channels over 4G and Wi-Fi networks in oil, gas, petrochemical, and pharmaceutical facilities without deploying private RF antenna masts.
-
Lone Worker Protection (LWP): Utilise integrated motion, tilt, and pressure sensors alongside the dedicated red SOS emergency key for automated man-down detection and distress signalling.
-
High-Noise Industrial Operations: Deliver loud, intelligible voice communications in operating process plants and near heavy rotating machinery using an amplified front loudspeaker outputting greater than 105 dB.
-
Bulk Grain & Explosive Dust Handling: Execute daily plant rounds, maintenance sign-offs, and logistics coordination in Zone 21/22 combustible dust atmospheres.
Rugged Durability
The IS380.1 is certified for use in potentially explosive atmospheres under ATEX Zone 1/21 (II 2G Ex ia IIC T4 Gb, II 2D Ex ia IIIC T135°C Db) and IECEx (Ex ia IIC T4 Gb, Ex ia IIIC T135°C Db), ensuring certified intrinsic safety against flammable gases, mists, and combustible dust particulates. The ruggedised housing holds an IP68 ingress protection rating, sealing internal electronics against fine dust ingress and continuous water immersion. Built to MIL-STD-810H standards, the terminal withstands mechanical shock, drop impacts, and industrial vibration. Operational temperature resilience is rated from -20°C to +55°C, ensuring reliable operation across extreme Australian climate conditions. Display optics are protected by 3rd generation Corning® Gorilla® Glass to resist surface abrasion and impact cracking.
