An embodiment of the present invention relates to a communication technology, and more particularly, to a technology for implementing wireless communication using an existing wired network.

Currently, service providers are expanding the wireless communication service area and reducing cell radius to provide high-speed wireless data communication. A cell means a minimum range of a communication service area that one base station can cover. Cells for wireless communication are classified into macro cells, pico cells, femto cells, etc. according to the number of communication users and the communication environment.

Here, the smaller the size of the cell is, the higher the frequency reuse rate can accommodate more communication subscribers. However, if the size of the cell is small, there is a problem that additional cost is increased as the communication service area is expanded. For example, if the size of the cell is small, a large number of repeaters must be added and installed when expanding the communication service area, thereby increasing additional costs such as management costs.

Therefore, there is a need for a method of expanding a communication service area and implementing high-speed data communication by using an existing communication network and infrastructure without installing an additional repeater.

An embodiment of the present invention is to provide a wireless communication system that can expand the communication service area by using the existing wired infrastructure by installing a wired or wireless communication device at the end of the cable pre-installed in the building.

Other technical problems by the embodiments of the present invention can be understood by the following description, which can be realized by the means and combinations thereof shown in the claims.

The wired / wireless communication device converts an RF signal transmitted from the wireless terminal into a wired signal and then transmits the wired signal to a device connected to the other end of the cable through the cable.

According to embodiments of the present invention, by installing a wired or wireless communication device to the end of the cable used in the existing wired network to perform wireless communication with the wireless terminals, it is possible to expand the wireless communication area without additional equipment such as communication network construction or repeaters. It becomes possible. Given the fact that most buildings have cables installed, a large number of wireless communication service areas can be expanded simply by installing wired and wireless communication devices at the end of the cable.

The cable 104 uses that of the existing wired network. Due to the widespread use of the Internet, a wired or optical cable for each Internet is installed in each building. Therefore, if the existing wired or optical cable is used to expand the communication service area, wireless communication can be performed without additional equipment. It can be implemented. The cable 104 may be formed to extend to an existing cable for connection with the base station 102.

The wired / wireless communication device 106 performs wireless communication with the wireless terminals 108. In this case, the wire / wireless communication device 106 converts a signal transmitted from the base station 102 through the cable 104 into an RF signal and transmits the signal to the wireless terminal 108. In addition, the wire / wireless communication device 106 receives an RF signal transmitted from the wireless terminal 108, converts the RF signal into an electrical signal or an optical signal, and then transmits the RF signal to the base station 102 through the cable 104.

That is, the wire / wireless communication device 106 converts the wired signal from the base station 102 into an RF signal and transmits the RF signal to the wireless terminal 108, and converts the RF signal from the wireless terminal 108 into a wired signal. To the base station 102.

The wired / wireless communication device 106 is installed at the end of the cable 104 to perform wireless communication with a plurality of wireless terminals 108 inside and outside the building. In this case, since the wired / wireless communication device 106 only needs to cover an area inside and outside the building, there is almost no frequency interference.

The wireless terminal 108 is a terminal capable of wireless communication existing inside and outside the building where the cable 104 is installed. The wireless terminal 108 includes, for example, a mobile phone, a laptop, a PDA, a smart phone, a PC, a netbook, and the like. Can be.

The wireless terminal 108 performs wireless communication with the wired / wireless communication device 106. For example, the wireless terminal 108 transmits a signal for requesting predetermined data to the wired / wireless communication device 106 and receives an RF signal (including the requested data) transmitted by the wired / wireless communication device 106. .

Here, wireless communication such as Wireless Local Area Network (WLAN), Bluetooth (Blue Tooth), Zigbee, Ultra Wide Band (UWB), Home RF, and the like, is performed between the wired / wireless communication device 106 and the wireless terminal 108. Can be done.

As such, when the wired / wireless communication device 106 is installed at the end of the cable 104 used in the existing wired network to perform wireless communication with the wireless terminals 108, the wireless communication area is not required without additional equipment such as communication network construction or a repeater. You can extend it.

In addition, when the wired / wireless communication device 106 is installed at the end of the cable 104 existing outside the building, it is possible to replace the communication in the cell unit, thereby increasing the frequency reuse rate, thereby increasing the number of wireless terminals 108 ) Can be accommodated. On the other hand, using the wired network of the optical cable as the cable 104 enables high-speed data communication (for example, 1Gbps).

Embodiment of the present invention is to install the wired and wireless communication device at the end of the cable installed in the building by applying the wired and wireless manganese compatibility. In this case, the wired / wireless communication device serves as a kind of cell covering a narrow area (for example, a radius of 100 m). In this case, since the cable of the existing wired network is used as it is, the wireless communication area can be extended without additional equipment. Given the fact that most buildings have cables installed, a large number of wireless communication service areas can be expanded simply by installing wired and wireless communication devices at the end of the cable.

In addition, since the cover area of the wired / wireless communication device is narrow, the frequency reuse rate can be increased. That is, since the frequency used in the area covered by the predetermined wired / wireless communication device can be used in an area outside the cover area of the predetermined wired / wireless communication device, the frequency reuse rate is increased.
