Abstract

A wireless phone system comprises a base station and a wireless handset that selectively communicates with the base station using at least one of first and second wireless modes. The second wireless mode has a greater range and higher operating power than the first wireless mode.

Description

technical field [0001] This invention relates to radiotelephone systems, and more particularly to dual mode radiotelephone systems. Background technique [0002] Referring to FIG. 1, a wireless telephone system 10 includes a base station 12 in wireless communication with one or more wireless handsets 14-1, 14-2, . . . and 14-N (collectively wireless handsets 14). Each of the wireless handsets 14 includes rechargeable batteries 16-1, 16-2, ... and 16-N (collectively batteries 16) that provide power during operation. Base station 12 is connected to telephone exchange 24 by telephone line 20 . Base station 12 and wireless handset 14 typically communicate using wireless link 26 . For example, wireless link 26 may operate at 900MHz, 2.4GHz, 5.8GHz, or other operating frequencies. Base station 12 may independently function as a wired telephone and / or answering machine. [0003] The range or operating distance of a wireless handset 14 can often be an important factor when purch...
