The Cisco© Wireless IP Phone 8821 is a ruggedized, resilient, and secure 802.11 wireless LAN handset that delivers cost-effective, on-premises, comprehensive Voice over Wireless LAN (VoWLAN) communications for the highly mobile in-campus worker.
The 8821 is specifically designed for workers whose roles are in more rigorous, industrial settings. Examples of ideal use cases include nurses and doctors in healthcare, operations and engineering staff in manufacturing, customer service representatives in retail, service staff such as maids in hospitality, and workers on rigs in the oil and chemical industries.
While the 8821 is sleek and lightweight, the design is hardened for users. It is Ingress Protection standard (IP54) rated and is sealed for protection against dust, splash and water. The device is also MIL-STD-810G tested, with a dozen drops onto concrete from heights of up to 5 feet (1.5 m), to help ensure shock resistance and avoid breakage if dropped.
The 8821 enhances security and simplifies configuration management. Stronger encryption is supported for certificate management and policy enablement with the support of Secure Hash Algorithm 2 (SHA-2). Simple Certificate Enrollment Protocol (SCEP) eases IT administration by enabling automatic certificate management on the device.
End users will enjoy a larger, higher-resolution color display and a user experience that is common with Cisco IP Phone 8800 Series desk phones. In addition, roaming between access points within the campus will support more seamless voice communications with the 8821’s support of Fast Transition (802.11r). This protocol was specifically designed for mobile Voice over IP (VoIP) communications devices within Wi-Fi networks. Bluetooth is supported for the user’s choice of third-party wireless headsets and adds freedom by untethering the user from the handset.
The 8821 supports Cisco and/or third-party XML applications such as push-to-talk.
A full suite of accessories, including desktop chargers, cases, holsters, and multicharger, are available from Cisco to support deployments. Consult the Cisco Wireless IP Phone 882x Series Accessory Guide options and details.

The Cisco Wireless IP Phone 8821 utilizes a lithium ion battery. Table 6 compares the talk time between the original and new Cisco Wireless IP Phone 8821 desktop chargers and Cisco Wireless IP Phone 8821 multichargers.
Table 6. Comparison of talk times
| Condition | Original chargers | New chargers |
| Phone charged in charger, with wall adapter, or with USB Phone running Firmware Release 11.0(4) SR3 or earlier | 9.5 hours | 9.5 hours |
| Phone charged in charger, with wall adapter, or with USB Phone running Firmware Release 11.0(5) or later | 11.5 hours | 11.5 hours |
| Spare battery charged in the charging slot | 9.5 hours | 11.5 hours |
A fully charged battery provides:
● Up to 11.5 hours of talk time (depending on the phone firmware and charger version)
● Up to 145 hours of standby time (auto-scan)
● Up to 45 hours of standby time (continuous scan)
Note: For voice calling, battery hours are calculated by placing a call and measuring the time it takes for the battery to completely drain. Actual battery hours may vary depending on display and keypad activity, messaging from an XSI application, roaming events and scan mode, and use of a Bluetooth headset. Under normal usage, when guidelines for battery in the deployment guide are followed, battery hours should cover a typical work shift of eight hours. For more information on battery performance refer to the Cisco Wireless IP Phone 8821 Battery Performance white paper.
Cisco IP phones are covered by a Cisco standard 1-year replacement warranty. A Cisco Smart Net Total Care® optional service agreement is available for the Cisco Wireless IP Phone 8821, desktop charger, and multicharger only, not for other accessories, such as batteries and carrying cases. The 8821 battery has only a 90-day warranty.
● This product is not a medical device and should not be used to make clinical decisions. This product may use an unlicensed frequency band that is susceptible to interference from other devices or equipment, and does not guarantee the delivery of messages to a WLAN device.
● A moist cloth can be used for simple cleaning. For the healthcare environment, Caviwipes and Saniwipes are the popular recommended choice for thoroughly cleaning the phone. Caviwipes and Saniwipes contain up to 17 percent isopropanol. Any cleaning solution containing a higher degree of isopropanol, including pure isopropanol, or an alternate alcohol-based liquid could potentially damage the phone. Refer to the Cisco Wireless IP Phone 8821 and 8821-EX User Guide for detailed instructions.
● Carry cases can help protect the phone and provide drop protection.
● The Cisco Wireless IP Phone 8821 was tested under controlled laboratory conditions with a rating of IP54 under IEC standard 60529. Splash, water, and dust resistance are not permanent conditions, and resistance might decrease as a result of normal wear. Users are expected to take care of the Cisco Wireless IP Phone 8821 and should not deliberately expose the device to a hostile environment of dust, splash, or water immersion. Do not attempt to charge a wet Cisco Wireless IP Phone 8821 or dock it on a desktop or multicharger. Refer to the Cisco Wireless IP Phone 8821 and 8821-EX User Guide for cleaning and drying instructions. Liquid damage to the Cisco Wireless IP Phone 8821 is not covered under warranty.
● Use only batteries that are approved by Cisco. Use of unapproved batteries might be dangerous, and will invalidate the warranty on your phone.
