Product Overview
Uphone introduces the Uphone L283 4G Rugged PoC Radio, a tough, bar-type IP68 4G PoC radio built for nonstop communication in the harshest industrial environments. As a dedicated 4G rugged PoC radio manufacturer, we combine global 4G LTE connectivity with military-grade durability to deliver instant Push-to-Talk (PTT) group calls, private messaging, and nationwide coverage — without the licensing hassles or limited range of traditional two-way radios.
The bar type 4G rugged PoC radio features a ruggedized bar design with large, glove-friendly buttons and a clear display, making one-handed operation easy even in gloves or wet conditions. IP68 waterproof and dustproof rating, combined with drop resistance, ensures it survives rain, mud, dust storms, and accidental drops on job sites. The long-life battery supports extended shifts without frequent charging, while global 4G bands (including LTE FDD/TDD, WCDMA, GSM) provide seamless roaming across regions — ideal for international projects or multi-site operations.
Instant Nationwide PTT Communication: 4G network delivers crystal-clear group and private calls with near-zero latency — far beyond the range limits of traditional analog radios.
IP68 All-Weather Durability: Fully sealed against water, dust, and drops, making the IP68 4G PoC radio reliable in rain, construction sites, or outdoor logistics.
Ergonomic Bar-Type Design: Large buttons and balanced grip allow fast, one-handed use even with gloves — perfect for security or field teams.
Long Battery Life & Easy Charging: Extended runtime reduces downtime and battery swaps during long shifts.
Cost-Effective Alternative: No license required, low monthly data plans, and rugged build lower total ownership costs compared to traditional systems.
Flexible Customization: Tailor PTT groups, emergency SOS, GPS tracking, or integration with existing dispatch software.
