A battery sized for long shifts

A guard on a residential compound or a housekeeping supervisor in a Makkah hotel carries the phone for hours on end. The WP822's 2000 mAh battery is rated for 8 hours of continuous talk, ahead of the WP810's 6 hours and the WP820's 7.5 hours. Standby reaches 200 hours, so on quieter days the handset will not die halfway through a shift.

Roaming without dropped calls

The phone runs 802.11ac on both bands and supports the 802.11k, 802.11r and 802.11v roaming standards. Together they speed up the handover from one access point to the next, so a call carries on as you walk from the building to the yard or between hotel floors. A multi-antenna design helps keep the connection stable.

Bluetooth, accelerometer and push-to-talk

Built-in Bluetooth pairs a wireless headset, so a warehouse worker can carry stock or type while talking. The accelerometer supports configurable gestures, and a customizable push-to-talk key reaches the whole team in one press. Dual microphones with echo cancellation and noise reduction keep voices clear.

Network security and management

The WP822 joins WPA3 and WPA3-Enterprise networks and supports SRTP and TLS call encryption plus 802.1x. IT can provision handsets in bulk with 256-bit AES encrypted XML and update firmware over HTTP, HTTPS, TFTP or FTP.

Where it fits in Saudi Arabia

• Security teams in residential compounds and towers.
• Housekeeping and maintenance staff in Makkah and Madinah hotels.
• Warehouses and distribution centers running two shifts.
• Large farms and rest houses covered by Wi-Fi.

Works with your existing PBX

The phone registers over standard SIP to Grandstream UCM, Yeastar and any other SIP IP PBX. Pair it with good Wi-Fi coverage, such as Grandstream GWN7660 access points.

WP822 vs WP820 vs WP810

The WP820 shares the 2.4-inch screen but runs Android 7.0, with Bluetooth 4.2, a 1500 mAh battery and 802.11n only. The WP810 has a 1.8-inch screen and a 1500 mAh battery, with no Bluetooth. Choose the WP822 when battery life and WPA3 matter more than running Android apps.
