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.

Features

The Cisco Wireless IP Phone 8821 (Figure 1) is designed for users in rigorous workspaces as well as general office environments. It supports a wide range of features for enhanced voice communications, Quality of Service (QoS), and security. Some of the main benefits and highlights are listed here:

     IEEE 802.11a/b/g/n/ac radio for VoWLAN communications support

     The large 2.4-inch (6 cm) color (240 x 320 pixels) display makes viewing easy

     IP54-rated for protection against dust, splash, and water

     MIL-STD-810G standard for shock resistance

     The phone offers exceptional voice quality with High-Definition (HD) voice

     A built-in full-duplex speakerphone offers high-quality hands-free communications

     The phone supports third-party Bluetooth 3.0 headsets and a 3.5-mm headphone jack for added freedom

     The Applications key provides direct access to XML applications such as push-to-talk and Lone Worker

     Battery life delivers up to 11.5 hours of talk time

     Enhanced encryption support for SHA-1 and SHA-2 signatures

     Fast, secure roaming using 802.11r and Cisco Centralized Key Management roaming

     Automatic certificate renewal – SCEP support
