ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to wireless telephone communications equipment. More specifically, this invention relates to equipment for receiving, converting and distributing wireless radio frequency signals using AC power line distribution channels.
2. Description of Related Art
A variety of power line carrier telephone voice and/or data communication systems have been developed and are used to facilitate telephonic communications in locations where little or no availability exists for dedicated telephone wires. While these devices provide a connection to the existing power lines they do not provide a means of distributing communication systems using standard “wired” telephone communication equipment and AC power line signal distribution. Such communication systems include: personal communication systems (“PCS's”); cellular telephone; and satellite telephone systems. The reader is directed to the following United States and foreign patent documents for background on power line communication systems: 2,510,273, 2,516,211, 2,516,763, 2,535,446, 2,567,908, 2,577,731, 2,654,805, 2,820,097, 2,828,363, 2,932,794, 3,045,066, 3,280,259, 3,334,185, 3,369,078, 3,399,397, 3,400,221, 3,475,561, 3,521,267, 3,529,216, 3,659,280, 3,693,155, 3,810,096, 3,818,481, 3,846,638, 3,852,740, 3,876,984, 3,911,415, 3,922,664, 3,924,223, 3,925,763, 3,925,728, 3,942,168, 3,949,172, 3,967,264, 3,973,087, 3,980,954, 4,012,733, 4,012,734, 4,016,429, 4,057,793, 4,058,678, 4,065,763, 4,107,656, 4,161,027, 4,173,754, 4,174,517, 4,218,655, 4,222,035, 4,239,940, 4,254,403, 4,307,380, 4,321,581, 4,323,882, 4,344,066, 4,357,598, 4,371,867, 4,377,804, 4,386,436, 4,400,688, 4,408,185, 4,408,186, 4,429,299, 4,433,326, 4,442,319, 4,471,399, 4,473,817, 4,475,193, 4,479,033, 4,495,386, 4,514,594, 4,523,307, 4,535,447, 4,538,136, 4,556,864, 4,556,865, 4,556,866, 4,559,520, 4,599,598, 4,609,839, 4,611,274, 4,633,218, 4,638,298, 4,638,299, 4,641,126, 4,641,322, 4,642,607, 4,644,321, 4,675,648, 4,701,945, 4,745,391, 4,745,392, 4,746,897, 4,749,992, 4,759,016, 4,763,103, 4,772,870, 4,774,493, 4,783,780, 4,788,527, 4,809,296, 4,829,570, 4,835,517, 4,845,466, 4,847,903, 4,864,589, 4,866,733, 4,890,089, 4,912,553, 4,962,496, 4,963,853, 4,968,970, 4,988,972, 4,995,053, 5,003,457, 5,032,833, 5,049,876, 5,063,563, 5,065,133, 5,066,939, 5,136,612, 5,151,838, 5,155,466, 5,168,510, 5,187,865, 5,192,231, 5,210,518, 5,241,283, 5,257,006, 5,262,755, 5,274,699, 5,278,862, 5,289,476, 5,319,634, 5,327,230, 5,349,644, 5,351,272, 5,355,114, 5,357,541, 5,404,127, 5,406,248, 5,406,249, 5,410,292, 5,412,369, 5,424,709, 5,448,593, 5,452,344, 5,461,629, 5,463,662, 5,467,011, 5,471,190, 5,504,454, 5,530,737, 5,530,741, 5,550,905, 5,554,968, 5,559,377, 5,630,204, GB 544,243, GB 549,948, GB 553,225, GB 683,265, GB 1,393,424, GB 2,094,598, AU-B

SUMMARY OF THE INVENTORY
It is desirable to provide a method, system and devices which enable the use of AC power line communication for the distribution of signals from a wide variety of communication sources and which is adapted to provide a seamless interface with standard telephone equipment.
Therefore, it is the general object of this invention to provide an interface between wireless communication devices, power line signal distribution, and standard telephone subscriber equipment.
It is a further object of this invention to provide a power line communication interface that is adapted to send and receive signals to and from personal communication systems (“PCS's”).
It is a still further object of this invention to provide a power line communication interface that is adapted to send and receive signals to and from cellular telephone devices.
It is another object of this invention to provide a power line communication interface that is adapted to send and receive signals to and from satellite communication devices.
It is a further object of this invention to provide a power line communication interface that is adapted to cooperate with standard wired telephone communication systems as are commonly installed for residential, business and government users.
It is still another object of this invention to provide a power line communication interface that has a base station for communicating with the standard telephone lines and with a remote telephone unit, using standard AC power lines as the communication channel.
A further object of this invention is to provide a power line communication interface that uses spread spectrum modulation techniques to communicate between the various communication devices.
Another object of this invention is to provide a system for integrating wireless communication equipment with existing typical wired telephone equipment, thereby permitting the user to take advantage of new and evolving personal communication systems while continuing to use existing wired telephone equipment.
These and other objectives of this invention further described in this disclosure and are readily apparent to those of ordinary skill in the art upon review of the following drawings, detailed description and claims.
