发明名称 MULTIFUNCTION WIRELESS DEVICE
摘要 A communication device and system are disclosed for providing communication and data services to residents of a controlled facility. The device can be restricted to communicating only using an internet protocol so as to restrict the device communication to an internal intranet. Wireless access points may be disposed throughout the environment to route calls and data between the device and a central processing center. By converting a protocol of the communications received from the device to a protocol used by the central processing center, minimal modifications to the central processing center are needed to support a wireless communication infrastructure. Many restrictions and safeguards may be implemented within the phone and system in order to prevent improper use.
