1 and 2, the sub AP 1 includes a keystone jack 10, a WiFi module 20, and a sub-controller 30. Here, the sub controller 30 is divided into a keystone jack function providing module 31, a Power over Ethernet (PoE) providing module 32 and an IoT (Internet of Things) network providing module 33.

In this specification, a module may mean a functional and structural combination of hardware for carrying out the technical idea of the present invention and software for driving the hardware. For example, the module may mean a logical unit of a predetermined code and a hardware resource for executing the predetermined code, and it does not necessarily mean a physically connected code or a kind of hardware. Can be easily deduced to the average expert in the field of < / RTI >

Hereinafter, the sub AP (1) will be described in detail with reference to the detailed configuration of the sub controller (30).

The keystone jack function providing module 31 performs monitoring on the keystone jack 10 formed on the front surface of the sub AP 1 housing to accommodate the UTP CAT.5E (Category 5e) Ethernet cable which is DATA wiring.

Here, it is preferable that the keystone jack 10 is formed by integrating a dedicated holder capable of interfacing with high-speed high-speed connection characteristics only by inserting an UTP CAT.5E (Category 5e) Ethernet cable.

When the UTP CAT.5E (Category 5e) Ethernet cable is inserted into the keystone jack 10, the keystone jack function providing module 31 notifies the PoE providing module 32 to request a power management function, To set up a data session for communication with the main AP 2. Here, the keystone jack 10 is a UTP CAT.5E (Category 5e) Ethernet cable for establishing a data session with the main AP 2, or a UTP CAT.5E (Category 5e) Ethernet cable for establishing a data session with an external wired terminal Can be selectively inserted.

The PoE providing module 32 can transmit and receive data using a UTP CAT.5E (Category 5e) Ethernet cable under the control of the keystone jack function providing module 31, And is formed to support an intelligent power supply surveillance function to the wireless device 3 as a terminal.

That is, the PoE providing module 32 designates and uses a predetermined core wire among the core wires of the UTP CAT.5E (Category 5e) Ethernet cable to supply power to the sub AP 1 It does not require a separate power cable and power supply, and supports intelligent power surveillance so centralized power management is possible. The keystone jack 10 under the control of the PoE providing module 32 operates as a data port when the power of the sub AP 1 is turned off and is utilized as a bedroom data port .

The IoT network providing module 33 manages the femtocell coverage (hereinafter referred to as 'current femtocell coverage') of the sub AP 1 provided therein. That is, as shown in FIG. 3A, the IoT network providing module 33 solves the problem that only a coverage of the same size can be set in the case of wireless coverage setting for a plurality of wireless APs by a conventional router, thereby causing a lot of interference.

Accordingly, as shown in FIG. 3B, the IoT network providing module 33 enables coverage setting according to the situation of each sub AP 1, and optimizes coverage to minimize interference with other sub APs.

To this end, the IoT network providing module 33 controls the radio signal output of the antenna included in the WiFi module 20 under the control of the main AP 2. That is, the IoT network providing module 33 broadcasts a radio signal of a preset size at the time of manufacturing each of the sub APs 1, thereby eliminating output of radio signals of uniform sizes of all the sub APs 1 The radio signal output is set in consideration of the size (large and small) and structure of each room in which the sub AP 1 is installed, signal interference factors (blocking / opening by walls and obstacles), and installed positions.

The IoT network providing module 33 extracts the radio signal control factor when receiving the radio signal control factor transmission request from the main AP 2 and then transmits the radio signal control factor to the main AP 2 through the data cable connected to the main AP 2. [ (2).

Here, the IoT network providing module 33 extracts, based on the strength of a wireless output signal outputted in at least four directions, eight directions, or the like with respect to the WiFi module 20 as one extraction method for a wireless signal adjustment factor, (Size / size) and structure, signal interference factors (blocking / opening by walls and obstacles) and installed location information are analyzed through the analysis of the stored DB through the strength of the received and reflected signal can do.

In another embodiment of the present invention, the IoT network provision module 33 controls the keystone jack 10 to access the storage unit of the main AP 2, reads the radio signal conditioning factor stored in the storage unit , And requests the main AP 2 to set the strength level of the radio signal output low or high in a stepwise manner (step 1 to step m) according to the read radio control factor, The intensity of the signal can also be adjusted.

Here, the storage unit may be formed of one of a main storage unit and an auxiliary storage unit. The storage unit may be a non-volatile memory (NVM) , MRAM (Magnetic Random Access Memory), PRAM (Phase Change Random Access Memory), and FRAM (Ferroelectric RAM).

The IoT network providing module 33 handles handover when it is detected by a single wireless device 3 to move to the current femtocell coverage or to move from the current femtocell coverage to another sub AP 1. That is, the IoT network provisioning module 33 keeps the data session connection between the femtocell coverage of the previous sub-AP 1 and the current femtocell coverage, and the current femtocell coverage and the sub-AP 1 after the handover.

4, the IoT network providing module 33 provides a roaming service on the ESS distributed network and provides a handover function when changing the femtocell AP of the wireless device 3 serving as a service using terminal Ensure smooth service without interruption of session. Specifically, FIG. 4A shows a separate access procedure (login) when moving between wireless APs under the control of an existing router. Even if two wireless APs are located under the same router, data sessions are different from IP, There has been an inconvenience in moving the AP of the device 3. To solve this problem, the IoT network providing module 33 allows the wireless device 3 to regard the sub-AP 1 in the ESS distributed network as the same network, so that even if the femtocell coverage of the sub AP 1 changes So that there is no change in IP or session, so that the mobile wireless device 3 provides a convenient service as if it accessed one sub-AP (1).

The IoT network providing module 33 receives the wireless transmission / reception signal output setting information from the main AP 2 and then transmits the wireless signal of the antenna of the WiFi module 20 to match the received wireless transmission / Adjust the output. In other words, as shown in FIG. 5A, it is difficult to access a plurality of wireless APs by a conventional router, and it is difficult to intuitively monitor on the main AP 2 because access between the router and each wireless AP is difficult.

Accordingly, the IoT network providing module 33 can conveniently receive the information of the sub AP 1 that provides the current femtocell coverage through data transmission / reception with the main AP 2, thereby adjusting the radio signal output. Also in this case, the main AP 2 can intuitively monitor the setting information for each sub AP 1 at a glance, and provides an advantage of being very convenient to set.

The present invention can also be embodied as computer-readable codes on a computer-readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) .

The computer readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And functional programs, codes, and code segments for implementing the present invention can be easily inferred by programmers skilled in the art to which the present invention pertains.
