Product description

Grandstream WP816 for Flexible WiFi 6 Business Communication

The Grandstream WP816 is a cordless WiFi IP phone designed for mobile professional communication. Its ergonomic design, WiFi 6 connectivity and roaming capabilities help users remain connected while moving throughout compatible wireless environments.

Dual-band WiFi 6 for reliable wireless mobility

The WP816 supports dual-band WiFi 6 on 2.4 GHz and 5 GHz networks, with compatibility for 802.11a/b/g/n/ac/ax. An efficient antenna design and support for advanced roaming help provide reliable wireless performance when users move around the workplace.

Two SIP accounts for flexible IP telephony

Support for 2 SIP accounts and 2 lines enables users to manage multiple business communications from a single cordless handset. This provides greater flexibility for employees who need IP telephony without remaining at a fixed desk.

HD voice with Noise Shield Technology

The WP816 combines HD voice, dual microphones, acoustic echo cancellation and Noise Shield Technology. The noise reduction technology automatically helps block background noise to improve audio quality and clarity in busy working environments.

Battery life designed for mobile working

A rechargeable 1500 mAh Li-ion battery provides up to 6 hours of talk time and 120 hours of standby time. The USB Type-C port supports fast charging, helping users prepare the handset quickly for continued use.

Bluetooth, headset connection and Push-to-Talk

Integrated Bluetooth enables connection with compatible wireless headsets, while a 3.5 mm headset jack provides an additional option for audio accessories. The dedicated and customisable Push-to-Talk button gives teams rapid access to instant voice communication.

Customisable operation and simple WiFi connection

The handset can be adapted to different users through customisable soft keys, a quick-access key and configurable Push-to-Talk functionality. WiFi deployment can be simplified by scanning a barcode, and the device can be programmed to connect to a specific wireless network when switched on.

Centralised device management with GDMS

The WP816 supports the Grandstream Device Management System for centralised provisioning, management, monitoring and troubleshooting. GDMS also provides device and account management, configuration, firmware upgrades, monitoring, intelligent alarms and statistical analysis for individual devices or batches organised by site, group and model.

Use cases, connectivity and technical specifications

The WP816 is suited to professional users who need portable IP telephony across WiFi networks. WiFi 6, advanced roaming, Bluetooth, Push-to-Talk and configurable controls make it suitable for mobile teams and working environments where users regularly move away from a fixed workstation.
