Cisco Wireless IP Phone 7920
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. Instead, he said, it was intended for use exclusively within an enterprise.
Between rechargings of the battery, the 7920 is claimed to deliver two hours of "talk time" and twenty-four hours of "standby time" (which presumably means it is switched on, yet idle) (ComputerWeekly.com Ltd., 2003). 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 protocol.
