Description

RESIDENTIAL USERS' CONNECTIVITY MODALITY TO INTERNET WITHOUT USING TELEPHONE LINES

The actual patent refers to a group of equipments well-known by telematics and computer science markets. Its use modality allows connection or access of microcomputers (PCs) to Internet Worldwide Web without needing to use fax/modem or modem cards and telephone lines. The access systems to Internet now in use in the world have a principle called remote access. This principle uses a technology guided to connections based on fax/modem or modem cards that have the function to transform microcomputer digital signals in analogic signals and to inject them in telephone lines making them to arrive to remote places.

By using this technology and with the growth of Internet, an user of a personal microcomputer is forced to connect to a telephone line or terminal in order to access this great Worldwide Web of information by means of known access servers.

This technology generally has been creating great problems to telephone concessionaires and its users. Such concessionaires have strong increment of data transmission, when in principle the main objective of a telephone line is to transmit voice.

Therefore, in the actual state of technique in Internet server section in the world, the user must acquire and install a fax/modem or modem card— that can be a external device instead of a card — and must occupy a telephone line to accomplish the connection. It is still necessary that its server also has fax modems or modems and available telephone lines to make the necessary connection in order the user accesses to Internet. In this way there is a financial tariff due to using this type of communication mean and its equipments, beyond, of course, technological limiters such as low connection speed that such telephone lines cause. Now a typical server of a great city in Brazil has dozens, hundreds and even thousands of telephone lines. in the current state of technique that is show in drawing form in Illustration 1 that integrates the present report, the user's microcomputer (1) is connected by a serial cable (2) to a fax/modem or external modem (3). This peripheral device (3) is also found in internal versions — called as "fax/modem or modem cards."

The fax/modem or modem (3) is then connected to telephone net by a telephone line cable (RJ11 or Telebras pattern) (4). In this cable the signal of user's computer travels to the telephone exchange, and, there, it is distributed to the telephone exchanges as much as are necessary until arriving to user's server.

In the server, a great number of telephone lines (5) need to be available to allow a great number of users can be connected simultaneously, because it is necessary a line or communication channel for each microcomputer of the connected user.

It is also necessary that those lines are connected to equipments such as fax modem or modem (6) to make compatible the signal transported by telephone concessionaire of the user until the signal gets the digital equipments of the server — using for that purpose serial cables of connection (7).

In this way, and generally, in a server there are as much telephone lines or channels as the quantity of users that can connect simultaneously to Internet, and the same quantity of fax/modem or modem as well.

Those fax/modems or modems (6) are connected to a equipment called

Remote Access Server— RAS (8). Its function is allowing users to be connected in a remote way (that is, physically external to the server) to the Signal Repeater of the server (10)— known also as HUB— using a net cable either UTP pattern (9) (EIA-TIA- 568 A or B norm) or coax pattern. The Repeater (10) has the function of concentrating, amplifying, and controlling several signals of several existent equipments in the server. By Remote Access Server (8), this Signal Repeater (10) interconnects the user's microcomputer (1) to server microcomputers (12) by cable (11) either UTP pattern (EIA-TIA-568 A or B norm) or coax pattern, and also to the Router (14) by UTP cable (13) (EIA-TIA-568 A or B norm) or coax cable, so allowing users connecting to Worldwide Web Internet (15).

That system results slow and costly, harming the progress of voice communications in the world, since more popular layers end to have their telephone lines rearranged in an indirect way for data communication area. In addition, that system is aimed of users' constant complaints not only in Brazil, but in all over the world.

It must be observed that in area of current state of technique, the telephone concessionaires will never get to perform its main role of making available telephone channels of voice communication for whole population, given the demand that privileged classes generate in using Internet.

The aim of present patent proposes use modality that is formed by several interconnected equipments and they are programmed in a way to allow using available products in the market that facilitates users of personal microcomputers to have access to Internet without using telephone lines of any nature. This modality allows a high-speed connection, much higher of current speeds that are limited for current state of technique, besides a connection dedicated 24 hours a day, not generating extra-tariff by using communication caused also by current state of technique.

This modality allows yet several users in a same residence can have their microcomputers linked simultaneously to Internet. Initially one of the more important characteristics and it particularizes the modality now proposed, it is the fact of users' microcomputers need not internal cards or external modules with the function of fax/modem or modem. Consequently, this fact releases the usual filters of telephone line for protection against atmospheric rays, as well as it allows a high-speed connection for integral time without additional cost, and, obviously, without occupying any telephone line.

In the drawing of Illustration 2 that integrates the present report, the diagram of use modality is demonstrated for what is called Fixed Station, that is, microcomputers (PCs) and connection equipments fixed before transmission and reception by radio. What is inferred of the drawing of Illustration 2 we observed a user's microcomputer (1) in which a net card (2) of data communication (Ethernet pattern) is inserted. This net card undergoes a programming by software called "address programming CLASS A, B, or C," suitable to be used in Internet. In this way it is released the need of fax/modem or modem, as well as telephone line and the use of dialing module and telephone connection that accompany microcomputer operating system.

Then, it is used a UTP pattern cable (3) connectorized to RJ45 pattern connectors and in agreement with EIA-TIA-568 norm (A or B), also known as net cable in order to interconnect user's net card (2) to a equipment known as Signal Repeater or HUB (4). This connection (3) can also be repeated several times for several microcomputers (1). Those microcomputers (1) can also be alone in one residential room, or spread in several apartments of a building or condominium or even in a neighborhood.

The basic function of the Repeater or HUB (4) is concentrating, optimizing, amplifying, and controlling the coming electric signal of users' microcomputers (1), allowing also interconnection between the same ones.

Once the electric signals of microcomputers (1) found themselves concentrate in only one equipment (4), those are sent to another equipment known as Router (6) by a UTP pattern cable (5) in agreement with EIA-TIA-568 norm (A or B). The Router (6) receives a special programming and has the function of allowing to configure users' microcomputers (1) so that allows its communication with external world by a technique known as "gateway programming," besides transforming the electric signal that is in Ethernet pattern for a pattern that can be understood by transmitter and receiver radio equipment (8) which is connected with cable (7). That connection [from (6) to (8)] is accomplished by Interface Converter Cable (7), and it generally uses the conversion patterns for interfaces RS232C, V35, and G703.

The radio equipment (8) sends/receives the signal from/to transmitter/receiver antenna (10) by a coax cable of radio frequency (9). Then the signal travels from/to the signal concentrating station characterized by several antennas (11) which have for purpose to concentrate the signals of all users of the system and to connect them to the transmitter/receiver radios of the server (13) using coax cables (12) of radio frequency. Those radios (13) are connected to Routers (15) by Interface Converter Cables (14) similar to previously already explained (7).

The Routers (15) are connected to the Repeater (17) by UTP cables (16) connectorized in agreement with EIA-TIA-568 norm (A or B). Repeater function is concentrating, amplifying, and controlling its electric signals. Those cables are in the same quantity as many are the quantity of Routers (15) as many are necessary. And the Repeater is connected to the group of server computers (19) by DTP cables (18) similar to the previous ones (16). This group of server computers (19) has the characteristics of SERVER OF PRIMARY NAME, SERVER OF SECONDARY NAME, HOMEPAGE SERVER, SAFETY SERVER (technically known as "FIREWALL"), PROXY, ELECTRONIC MAIL SERVER, AND FILE SERVER.

Each server computer (19) is connected to the Repeater (17) by a UTP cable (18) as is shown in Illustration 2 that represents only one UTP cable for simplification effect, because the quantity of server computers (19) can vary in agreement with the need.

The whole group of equipments now described connects to the Router (21) by UTP cable (20), that through specific programming ends to make available the access in a controlled way to Internet Worldwide Web (22).

The use modality proposed has innovative characteristics, and, besides benefits that clearly identify themselves for all their users, it allows the telephone exchanges have an immediate rid of congestion now limited in face to technology and topology in use in the world and being consumed by Internet. Looking at the table below, one can observe the comparative data between the current system of residential connectivity to Internet and the use modality now proposed.
