We introduced the new Cisco Wireless IP Phone 8821 before. Now it comes to the new 8821-EX. What’s the relationship between the IP Phone 8821 and the 8821-EX? Well, The 8821-EX builds upon all of the features offered by the Cisco Wireless IP Phone 8821 and adds nonsparking support for temporary exposure within potentially combustible environments. It is ATEX Class I, Zone 2 and CSA Class I, Division 2 certified. ATEX Zone 2 is defined as an area in which an explosive gas atmosphere is not likely to occur in normal operation and, if it does occur, is likely to do so only infrequently and will exist for a short period only (for example, less than 10 hours per year). Similarly, CSA Class I is a location where a quantity of flammable gas or vapor sufficient to produce an explosive or ignitable mixture may be present in the air. Division 2 is a location where a classified hazard does not normally exist but is possible under abnormal conditions. Zone 2 is an area in which an explosive gas atmosphere does not normally exist.
While the 8821-EX is sleek and lightweight, the design is hardened for users. It is Ingress Protection standard (IP67) rated and is sealed for protection against dust and immersion in water. The device is also MIL-STD-810G tested, with a dozen drops onto concrete from heights of up to 6 feet (1.8m), to help ensure shock resistance and avoid breakage if dropped.
The 8821-EX enhances security and simplifies configuration management. Stronger encryption is supported for certificate management and policies enablement with the EX model’s 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 (Figure 1) 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-EX’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-EX supports Cisco and third-party XML applications such as push-to-talk.
The Cisco Wireless IP Phone 8821-EX delivers all the capabilities of the Cisco Wireless IP Phone 8821 with the ruggedness and resiliency certification needed for deployment in environments such as chemical and manufacturing plants, utilities, and oil refineries.
Note: For information about the desktop charger, multicharger, and carrying cases, refer to the Cisco Wireless IP Phone 8821 Accessory Guide.
The Cisco Wireless IP Phone 8821-EX is offered only in the World mode, and requires an access point that supports 802.11d to indicate which channels are to be used by the phone.
The Cisco Wireless IP Phone 8821-EX is IP67 rated, meaning that it is protected from dust, liquid splashes, moisture, and water immersion between 6 inches (15 cm) and 3.2 feet (1 m). 8821-EX device users are expected to close the battery door properly and inspect the door seal on a regular basis to maintain IP67 functionality support.
If you have workers who are mobile within a Wireless LAN (WLAN) enabled campus for much of their workday, and whose roles are more rigorous in nature requiring devices with resilient, hardened exteriors, then the Wireless IP Phones 8821 and 8821-EX may be of interest to you.
Notes: The 8821 phone is planned for availability June 2016 where country compliances have been achieved. The 8821-EX at time of this publication requires additional certification testing for combustible environments and is planned for Fall CY 2016. Please consult your Cisco representative or authorized Cisco reseller partner/distributor for further timing and availability details as these will vary by country and compliance testing they require.
Hardened exteriors that are military standard (MIL-STD 810G) compliant. These endpoints are tested for shock resistance by droptesting them a dozen times onto concrete from a height of 6ft (183cm) on different points of the handsets (face, top, bottom etc).
International Protection Standard 67 (IP67) rated for ingress of dust and water. The endpoints are sealed against dust and protected if immersed in water up to 1 meter (3.3 ft) for up to a half hour and will still function.
The 8821-EX builds upon the 8821 and delivers all its features. It is ideal for operation in settings such as oil and chemical facilities, where the handset could be operated during temporary exposure to a combustible atmosphere. Operation of the device would not ignite such an environment.
CSA Class 1, Division 2, Zone 2 certified. CSA Class 1 is a location where a quantity of flammable gas or vapor sufficient to produce an explosive or ignitable mixture may be present in the air. Division 2 is a location where a hazard does not normally exist but is possible under abnormal conditions. Zone 2 is an area in which an explosive gas atmosphere does not normally exist.
