Industrial-Grade Durability

The WP836 achieves IP67 certification, meaning it is completely dust-tight and can withstand immersion in water up to 1 meter deep for 30 minutes. The robust housing survives drops from 2.5 meters (over 8 feet) onto concrete—accidents that would destroy conventional phones. Operating temperature range spans 0°C to 45°C (32°F to 113°F) with humidity tolerance from 10-90%, enabling reliable operation in cold storage, outdoor sites, and tropical climates.

Antimicrobial Protection

The phone’s casing incorporates antimicrobial technology that kills 99% of harmful microbes, making it particularly valuable in healthcare, food processing, and pharmaceutical environments where hygiene is critical. The smooth, chemical-resistant surfaces can be thoroughly cleaned with disinfectants without damage, ensuring compliance with sanitation protocols.

Wi-Fi 6 Connectivity

Integrated dual-band Wi-Fi 6 (802.11ax) provides reliable, high-performance wireless connectivity throughout large facilities. The advanced antenna design and roaming support ensure seamless handoffs between access points as workers move through warehouses, factories, and multi-floor buildings. The phone automatically selects optimal channels and bands for best performance.

Exceptional Battery Life

The 3000mAh battery delivers 10 hours of continuous talk time and 240 hours of standby—a full shift and beyond on a single charge. USB Type-C fast charging quickly replenishes the battery during breaks. The included charging cradle makes it easy to keep multiple devices ready for the next shift.

AI-Powered Audio Quality

Dual microphones with AI-based noise reduction technology filter out background noise from machinery, vehicles, and busy environments. The noise shield technology ensures your voice comes through clearly even in the noisiest conditions. The powerful speaker delivers clear audio in loud environments, while acoustic echo cancellation prevents feedback.

Professional VoIP Features

The WP836 supports 3 SIP accounts and 3 lines, 4-way voice conferencing, HD voice with Opus codec support, and integration with major UC platforms. Customizable function buttons can be programmed for alarm activation, push-to-talk paging, or speed dial. The 2.8-inch color display provides easy navigation through contacts, call logs, and settings.

Safety Features

Built-in safety alarm functions alert designated contacts in emergency situations. Man-down detection senses falls and automatically triggers alerts. No-movement detection identifies prolonged inactivity that may indicate an injured worker. These features are essential for lone workers in hazardous environments.

Bluetooth Integration

Integrated Bluetooth 5.0 enables wireless connection to headsets and earpieces for hands-free operation. This is particularly valuable for workers who need both hands free while maintaining communication.

Ideal Applications

Warehouses and distribution centers, manufacturing floors, construction sites, oil and gas facilities, healthcare environments, outdoor security operations, retail stockrooms, and any workplace where durability, mobility, and reliable communication are essential.
