Need a robust, reliable phone in a harsh environment where there is dust, water, humidity, extreme temperatures, or some combination of these conditions? Or perhaps the nature of the work carries a risk of dropping the phone? Meet the Grandstream WP836 ruggedized Wi-Fi cordless phone.

In this article, we review some of the extraordinary characteristics that make this phone ideal for a variety of use cases.

Ruggedization and design

The Grandstream WP836 combines a wide variety of innovative characteristics that address a range of industry verticals and use cases. One of the WP836's most noteworthy features is its ruggedization. The device has an IP67 rating, ensuring that it is completely dust-tight and waterproof to the point that it can be immersed in water up to three feet in depth without harm. Its operating temperature ranges from 32°F (0°) to 113°F (45°C) with an operational humidity range of 10-90%. It has an antimicrobial casing to inhibit the growth and spread of bacteria, fungi, and other microbes on the phone's surface. It is highly durable and can be safely dropped from a height of up to six feet (two meters) without any damage.

The phone easily outlasts its competitors with 10 hours of talk time per charge and 10 full days of standby time provided by a rechargeable 3000 mAh battery. The phone can be charged within its charger base or via any Type C USB charger.

The phone's ergonomic size and shape fits comfortably in the hand. Its large display, intuitive interface, and extensive customization options enhance mobility and adaptability for diverse voice communication needs.

Grandstream WP836 additional features

The WP836's collective employment of Wi-Fi, SIP, Bluetooth, and AI-enabled audio, all packaged within a durable shell, makes it an exceptional offering. More details about these features are described below.

Wi-Fi-based connectivity

The device connects to the network via regular Wi-Fi. It supports conventional wireless protocols as well as the Wi-Fi 6 standard. It is important to ensure that the network being connected to has been designed appropriately to seamlessly support voice services. Coupled with Grandstream’s extensive portfolio of wireless access points, the WP836 makes a great addition to any wireless voice solution.

SIP-based voice services

Users can configure up to three SIP accounts, essentially resulting in three separate lines terminating on the device. This, along with the capability of a four-party conference call and the support of a wide variety of voice codecs, allows the WP836 to deliver exceptional flexibility in voice services. The phone also inherently supports many telephony features, including hold, transfer, click-to-dial, and server redundancy and failover.

Bluetooth support and AI-empowered audio

The WP836 sports integrated Bluetooth to wirelessly connect virtually any Bluetooth headset, adding hands-free capabilities to a highly mobile telephony experience. High-definition voice, acoustic echo cancellation (AEC), noise shield technology, and AI-driven noise reduction are all among this wireless telephone’s audio capabilities.

Comparison with the WP825

Grandstream is no newbie to the world of ruggedized Wi-Fi phone; the WP836 is the successor to the highly successful WP825 device introduced a while back. The newer phone delivers the same IP67 rating and robust features, but improves upon its battery capacity, providing autonomy for longer periods of time, and increases the number of SIP accounts from two to three. It also has a larger screen and a sleeker design.

Popular use cases
