ABSTRACT:

FIELD OF THE INVENTION
The present invention generally relates to the field of information handling systems, and particularly to a wireless communications interface between an information handling system and a standard modem.
BACKGROUND OF THE INVENTION
Standard interfaces for information handling systems typically utilize a physical wire for transmission of information between the information handling system and a peripheral device such as a modem. As a result, standard, lower cost peripheral devices are typically designed to couple to the information handling system via a physical wire. However, physical wires are limited to a predetermined length. In applications where the user desires the information handling system to by moved, relocated or otherwise utilized beyond the reach of the wire, the length of the wire becomes a limiting factor.
In systems where computer system mobility is required, specialized peripheral devices may be utilized which allow wireless communication between the information handling system and a remote device. However, the specialized wireless communication devices are often too costly and specialized for the typical user where the high cost of the specialized wireless devices cannot be justified. Additionally, the specialized wireless devices contain redundant electronics and must replace existing standard devices that the user may already own. Thus, it would be highly desirable to provide a wireless communication system for communicating between an information handling system and a standard peripheral device without the need for specialized wireless communication devices.
SUMMARY OF THE INVENTION
The present invention is directed to a wireless communications system for enabling an information handling system to wirelessly couple to a network. In one embodiment the wireless communications system includes a peripheral communications device for communicating information sent to and by the information handling system via a wireless transmission medium, wherein the peripheral communications device includes a device interface for interfacing with a bus of the information handling system, a first wireless transmission interface for transmitting and receiving information via the wireless communications medium, and a first controller for managing the transfer of information between the device interface and the wireless transmission interface. The wireless communications system additionally includes a base station coupled to the peripheral communications device via the wireless transmission medium for coupling with a network communications device wherein the information handling system is enabled to communicate over a network via the network communications device, wherein the base station includes an I/O interface for interfacing with the network communications device, a second wireless transmission interface for transmitting and receiving information via the wireless communications medium, and a second controller for managing the transfer of information between the I/O interface and the wireless transmission interface.
The present invention is further directed to a method for communicating between an information handling system and a network via a wireless transmission medium. In one embodiment the method includes the steps of sending information to be transmitted from the information handling system to a peripheral device of the information handling system, translating the information to be transmitted into a wireless data transmission format, transmitting the wireless data transmission formatted information via a wireless transmission medium to a remote device, receiving the wireless data transmission formatted information with the remote device, converting the received information into a network communications format, and sending the network communications formatted information to a modem connected to the network for transmission of the network communications formatted information via the network.
It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention and together with the general description, serve to explain the principles of the invention.
