The Wireless IP Phone 7920 is a mobile phone branded by Cisco Systems, Inc. that communicates via IEEE 802.11b technology. According to C. Giancarlo, senior vice-president of switching, voice, and carrier systems at Cisco (as cited in ComputerWeekly.com Ltd., 2003), the 7920 was not intended to replace traditional mobile phones.

Twenty-four hours is a relatively low level of standby time compared to GSM mobile phones, which can have standby times of a week or more. This is presumably due to the greater power requirements of the 802.11 hardware and the protocol's lack of power management.
