Phone Overview
The Cisco Unified Wireless IP Phone 7925G, 7925G-EX, and 7926G provides wireless voice communication
over an IP network. As with traditional analog telephones, you can place and receive phone calls and access
features such as hold, transfer, and speed dial. In addition, because the phone connects to your wireless local
area network (WLAN), you can place and receive phone calls from anywhere in your wireless environment.

The Cisco Unified Wireless IP Phone 7925G-EX is hearing aid compatible (HAC) but does not have any TTY
features. It also has a centered “dot”or “nib”on the 5 key that is a tactile identifier.
The physical characteristics include:
•Atmospheres Explosibles (ATEX) Zone 2/Class 22 certification prevents ignition of surrounding gas
vapors by the phone.
•Canadian Standards Association (CSA) Division 2/Class 1 certification provides access to mobile
collaborative communications.
•Industry-standard yellow styling offers fast recognition in emergency situations.
•Ingress Protection 64 (IP 64) level protection, indicating dust-tight equipment which is protected against
splashing water.
•The large 2-inch color (176 x 220 pixels) display makes viewing easy.
•Resistance to damage from dropping the phone.
•Tolerance of antibacterial and alcohol-based wipes.
•Latex- and lead-free.
•Shockproof and vibration-proof.
•USB 1.1 interface.
ATEX Zone 2 certification: 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).
Note
CSA Class 1 Division II certification: 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 II is a location
where a classified hazard does not normally exist but is possible under abnormal conditions.

Bluetooth Technology
The Cisco Unified Wireless IP Phones are full-feature telephones and a qualified Bluetooth wireless devices
(Qualified Device ID [QDID] B014396) and provide voice communication over the same wireless LAN that
your computer uses. In addition to basic call-handling features, your phone operates with Bluetooth wireless
headsets, including certain hands-free call features.
Bluetooth devices operate in the unlicensed Industrial Scientific Medicine (ISM) band of 2.4 GHz, which is
the same as the 802.11b/g band. This unlicensed band in most countries includes the frequency range from
2400 to 2483.5 MHz. Bluetooth enables low bandwidth wireless connections within a range of 10 meters.
The best performance is in the 1 to 2 meter range. Synchronous voice channels are provided by using circuit
switching and asynchronous data channels are provided by using packet switching.
Bluetooth uses integrated Adaptive Frequency Hopping (AFH) to avoid interference. Every 625 microseconds
(1/1,000,000 of a second) the channel changes or hops to another frequency within the 2402 to 2480 MHz
range. This equals 1600 hops every second.
The Cisco Unified Wireless IP Phones contain a Bluetooth module and 802.11 WLAN module. This coexistence
greatly reduces and avoids radio interference between the Bluetooth and 802.11b/g radio.
Bluetooth devices fit into to three different power classes, as shown in the following table.
