Description

The Cisco Wireless Phone 9821 is a ruggedised Wi-Fi 6E handset from the Cisco Wireless Phone 9800 Series, running PhoneOS and built for frontline and mobile workers. It suits clinicians in healthcare, warehouse staff in manufacturing, and retail and hospitality associates, particularly in noisy or demanding environments where shared-use rugged handsets are needed. This SKU is the handset only in Carbon Black, supplied as a spare unit.

The handset supports 802.11a/b/g/n/ac/ax across 2.4, 5 and 6 GHz, with 802.11r, k and v fast roaming and WPA2/WPA3 Personal and Enterprise security. It has a 2.4-inch IPS colour display at 240 x 320 pixels, Bluetooth 5.4 with BLE Audio, a 3.5 mm wired headset jack and a magnetic USB 2.0 OTG connector. The housing is IP54 rated and tested to MIL-STD-810G, and the 2060 mAh swappable battery delivers up to 11.5 hours of talk time and 145 hours of standby. A configurable Action button, push-to-talk and fall detection support worker safety. A phone technology licence is required for all Cisco IP phones.

It works with Cisco Unified Communications Manager 15 and above, Webex Calling, Webex Dedicated Instance, Cisco BroadWorks and third-party SIP platforms, and associates with Cisco IOS WLC lightweight access points and Cisco Meraki access points.
