The dual-band GSM/EDGE, dual-band W-CDMA device has its own external antenna and can be placed anywhere in a house where there is a wireless signal.

The WF720 runs on a Qualcomm QSC6270 processor with 64 MB RAM and has 128 MB of internal Flash memory. It’s powered by a 3.6 V, 1500 mAh NiMH battery that supplies a listed 1.5 hours of W-CDMA use, 3.5 hours of GSM use, and 36 hours of standby. A back-up battery is also included in the event of a power outage.
