Description

SYSTEM TO PROVIDE ENERGY TO AN IN-WIRED SYSTEM Background of the Invention The present invention is directed to a system for providing power to a receiver, within a wireless communication system. More particularly, the invention is directed to providing power from a local central company, to a wireless fixed transceiver, which is part of a wireless communication system. A proliferation of subscribers to wireless communication services has been observed in the market. Subscribers change to this type of services for a number of reasons. Among these reasons are the services that are offered in conjunction with the communications that are referred to as PCS, which combine voice capabilities and data messages. Moreover, subscribing to a wireless system typically has the ease of choice among service providers in an area of interest. In contrast to terrestrial telephone communication networks, where typically only one local service provider company is assigned to a given region, there may be three or four service providers within the region of interest given, depending on how many providers of service. service have been located, in accordance with frequency band assignments. Thus, it has become increasingly desirable to have the advantages of wireless communication available in fixed-base homes, in addition to providing the wireless communication capabilities of a mobile nature. The problem increases in conjunction with providing power to the wireless fixed transceiver. In one configuration, the energy can be derived, from local energy sources, such as an electricity company, through a converter connection, to a standard output of 60 Hz and 110 volts. This energy capacity, however, is vulnerable to power interruptions. As a consequence, the wireless transceiver will suffer a power failure in any prolonged duration and even when this can be operated in the short term with batteries, it will eventually become inoperative due to the absence of a power supply. It is known in the prior art, as shown in U.S. Patent Nos. 5,553,138 to Heald et al. , 5,343,514 of Snyder, 5,157,711 of Shimanuki and 4,232,200 of Hestad et al. , deriving energy for a communication instrument, from a landline connection, to a central station. However, in all these configurations the communication is carried out by the communication device that is on the same terrestrial line that provides power to the device.

There is still a need to find a more reliable source of power for a fixed wireless transceiver, to avoid service interruption in the event of power interruptions.

Brief Compendium of the Invention The present invention is directed to provide power to a wireless transceiver, so that it continues to operate despite interruptions in the supply of electrical power. This is accomplished in accordance with an embodiment of the present invention, in which the wireless transceiver is powered by a landline connection to a local central or central station. In one embodiment of the invention, the handset is part of the wireless transceiver and this transceiver includes a power converter, which receives the power from the landline connection and matches it to the power specifications of the cellular transceiver. In an alternative configuration, the wireless transceiver may be part of a base station with which a headset can communicate wirelessly. The energy conversion circuits are arranged in the base station, together with the wireless transceiver. This allows the user to have the benefits of a cordless phone, together with a fixed wireless transceiver, supplied by the local central company. Thus the wireless transceiver receives its power from the local central company, over a landline connection, which is not used for any other purpose, than that of receiving energy. As a consequence, the transceiver remains in operation even in the event of an interruption of electrical power, which could otherwise affect the appliances, in a location that is subject to power interruption.

Brief Description of the Drawings Fig. IA illustrates a telephone landline communication connection. Fig. IB illustrates one embodiment of the present invention.

Detailed description As described above in connection with the cited US Patents, it is known in the prior art that a landline telephone connection provides power from a central station to a room. For example, as shown in Fig. IA, a residence 10 is connected through the land line 20, to a central station 30.

The landline connection supplies power from the central station to the residence. The original intention to supply power from the central station, was to provide power to the telephone in operation, to provide the service to the end user (marking capabilities, power for the internal circuits of the telephone, etc.). The energy that has been supplied by the base station, as indicated in the aforementioned patents, has also been used to provide power to other communication elements, which interact with the land line to provide communication on the land line. For example, in U.S. Patent No. 5,553,138, the system provides power to a base station unit, which provides communication to the landline telephone, from a computer. The other patents show communication equipment, supplied with energy by means of the land line, on which communication occurs.

In the present invention, a fixed wireless transceiver provides wireless communication and even more is supplied with power, by means of a landline connection, connected to the central station. As illustrated in Fig. IB, a wireless transceiver 70 could take the form of a standard telephone, except that it includes an antenna for wireless communication to a base station similar to those of a cellular or wireless communication, toward a central station. The transceiver can be connected through a connector 60 to a wall socket to a receptacle unit 50, which is connected to the land line 20, which connects the residence 10, to a central station 30 (see Fig. IA) . In this configuration, the connector 60, in its connection to the receptacle unit 50, receives power from the land line 20. This energy is provided to the internal circuits of the wireless transceiver 70. The circuits, not shown, convert the received energy, to the appropriate power, prescribed by the specifications to operate the wireless transceiver. These circuits can be easily constructed by any person skilled in the art and can be considered analogous to the circuits already existing in cell phones, which derive energy for example, from automobile energy sources or domestic energy sources, for example, 110 volt AC power sources. The details of the circuits are not part of the basis of the present invention. In an alternative form, the present invention can be employed using an additional piece of equipment, call a local station. The base station may have the wireless transceiver included therein and may be connected to the 60, which is connected to the receptacle unit 50. A separate handset may be provided to communicate wirelessly with the base station. The circuits of the converter can then be arranged inside the base station and the wireless headset can communicate with the fixed wireless transceiver at the base station which is supplied with power by the local central company.

By implementing the present invention, a subscriber can have all the benefits of a wireless communication within a fixed location, at the same time reducing the vulnerability to power interruptions, which could otherwise damage the electrical appliances that were inside the premises. The present invention can also be easy to install in most places, since the premises typically have more than one telephone receptacle for a given land line, to a central station. Thus, a telephone line that is being used to provide the landline service for the residence or premises 10 may still provide the appropriate power to a wireless communication device both, as the communication device is connected to an outlet, the which is not currently serving a telephone or other communication device that interacts with the landline. The present invention then provides a dependent power supply for a wireless communication device that improves the communication capabilities of the subscriber, together with an uncomplicated installation. It is noted that, with regard to this date, the best method known by the requested, to carry out the present invention, is that which is clear from the present, discovering the invention. Having described the invention as above, the content of the following is claimed as property.
