The mobile device 200 may generate various messages or frames transmitted through the Wi-Fi network, which is one of the network networks provided by the access point 300, or may process frames received through the Wi-Fi network. The mobile device 200 can be, for example, a smart phone, a smart pad, a tablet PC, a Personal Communication System (PCS), a Global System for Mobile communication (GSM), a Personal Digital Cellular (PDC) Personal Handyphone System, PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication) -2000, Code Division Multiple Access (CDMA) -2000, W-Code Division Multiple Access (W-CDMA), Wireless Broadband Internet And may be any kind of wireless communication device.

The MAC address information collecting apparatus 100 can collect frames in the communication between the devices via the Wi-Fi network. The MAC address information collecting apparatus 100 may collect a frame of a device of a mobile device type or a device of a fixed device type. In one example, the MAC address information collection device 100 may collect frames in the communication between the access point 300 and the mobile device 200. [ As another example, the MAC address information collection device 100 may collect frames in communication between access points, or may collect frames in communication between mobile devices. The MAC address information collecting apparatus 100 may analyze the collected frames and classify the MAC address information corresponding to the mobile device 200 and the MAC address information corresponding to the fixed device. A detailed description of the classification of MAC address information will be given later.

The MAC address information collecting apparatus 100 may transmit the classified MAC address information to the server 400 and receive a response corresponding to the transmitted MAC address information from the server 400. [ The MAC address information collection device 100 may calculate the distance between the mobile device 200 and the MAC address information collection device 100 using the MAC address information corresponding to the mobile device 200. [ The MAC address information collecting apparatus 100 can provide various information and services to the mobile device 200 through the calculated distance, and can utilize the information as marketing information. The MAC address information collecting apparatus 100 may be included in the coverage of the Wi-Fi network transmitted from the access point 300, and may be provided in correspondence with the installed access points 300.

Here, an example of the response may include information relating to the mobile device such as identification information of the mobile device, service information corresponding to the mobile device, control commands of the mobile device, and the like.

As described above, the MAC address information collection system 10 has been schematically described. Hereinafter, the MAC address information collection apparatus 100 and the method will be described in detail with reference to FIGS. 2 to 6. FIG.

2 is a block diagram of a MAC address information collection apparatus 100 according to an embodiment of the present invention.

2, the MAC address information collection apparatus 100 includes a frame acquisition unit 110, a MAC address information extraction unit 120, a MAC address information classification determination unit 130, a distance calculation unit 140, A communication unit 160, and a storage unit 170. The communication unit 160 may include a communication unit 150, a communication unit 160, However, the MAC address information collecting apparatus 100 shown in FIG. 2 is only one embodiment of the present invention and can be modified into various forms based on the components shown in FIG. 2. However, It will be appreciated by one of ordinary skill in the art. For example, the features provided in the components and the components may be combined into a smaller number of components or further separated into additional components, and some components may be excluded.

The frame acquisition unit 110 may collect frames to be wirelessly transmitted. The frame acquisition unit 110 may collect frames transmitted and received in the Wi-Fi network transmitted from the access point 300. For example, in the Wi-Fi network, 14 channels having respective bands are formed, so that data communication can be performed for each channel. At this time, the frame obtaining unit 110 may collect frames from any one of the 14 channels.

The frame acquisition unit 110 may periodically change a plurality of radio channels and collect frames through any one of a plurality of radio channels. For example, the frame acquisition unit 110 may collect frames while moving the channels 1, 6, and 11 having the 2.4 GHz band. Wi-Fi channels have their own bands and can have overlapping bands of channels. Therefore, it is possible to collect a frame by selecting a channel having less interference between channels. Frame acquisition section 110 periodically changes channels and collects frames, thereby collecting frames of various devices. According to one embodiment of the present invention, the frame obtaining unit 110 may change frames to a channel every 10 seconds to collect frames. That is, if a frame is collected for 10 seconds in any one channel, the collection result may be transmitted to a MAC address information extraction unit 120 to be described later, and changed to the next channel to perform frame collection. The period of changing the channel, the channel to be changed, and the number of channels may be set, but are not limited thereto.

The MAC address information extraction unit 120 may extract MAC address information about the device from the frame. The MAC address information extraction unit 120 may extract MAC address information from the header of the frame. The MAC address information includes a source address (SA) as a MAC address of a device at which a frame starts, a destination address (Da) as a MAC address of a device that finally receives a frame, a wireless device (TA) (Transmitter address), which is a MAC address that identifies a wireless device, a Receiver address (RA), which is a MAC address that identifies a wireless device receiving a frame, and a basic service set identifier (BSSID) may be included. When the MAC address information extraction unit 120 extracts the MAC address information from the frame, the MAC address information classification determination unit 130 classifies the MAC address information according to the device type.

The MAC address information classification determination unit 130 may determine the MAC address information as the first classification MAC address information corresponding to the mobile device 200 or the second classification MAC address information corresponding to the fixed device based on the frame. When the MAC address information of the mobile device such as a smart phone or a PDA is detected from the transmission destination or the destination address in the frame field, the MAC address information classification determining unit 130 classifies the MAC address information into the first classification MAC address information, When MAC address information of a fixed device such as an access point, a PC, a router, or a beacon is detected from a transmission destination or a destination address in a frame field, the MAC address information is classified into second classifying MAC address information. Hereinafter, an embodiment in which the MAC address information classification determination unit 130 classifies MAC address information will be described.

If the MAC address information includes at least one of the broadcast address and the multicast address, the MAC address information classification determination unit 130 may determine the MAC address information as the second classification MAC address information. The broadcast address may be a MAC address of a frame transmitted to all hosts connected to the network. Since the broadcast address is FF: FF: FF: FF: FF: FF: FF, it can be determined that the broadcast address is not the MAC address of the mobile device, and can be classified into the second category MAC address information. The multicast address may be a MAC address of a frame transmitted to hosts belonging to a specific group connected to the network. The multicast address is an address assigned from 01: 00: 5: 00: 00: 00 to 01: 00: 5E: 7F: FF: FF in IPv4 and assigned as 33: 33: XX: XX: XX: XX in IPv6. Address. At this time, 33:33 is a fixed address, and XX: XX: XX: XX is an address that can be changed according to the group. Since the multicast address also has the specified MAC address, it can be determined that the multicast address is not the MAC address of the mobile device and can be classified into the second category MAC address information.

Meanwhile, the mobile device 200 can also perform broadcast and multicast functions. Therefore, it may happen that the MAC address information of the mobile device 200 includes a broadcast address or a multicast address. Therefore, even if a broadcast address or a multicast address is detected in the source address of the mobile device 200, the MAC address information classification determination unit 130 may determine that the MAC address information of the destination address is the same as that of the fixed device stored in the storage unit 170 In the case of the second classification MAC address information, which is the MAC address information, the broadcast address or the multicast address of the source address may not be classified as the second classification MAC address information. The storage unit 170 may store the first classified Mac address information or the second classified MAC address information. The storage unit 170 will be described later in detail.

The MAC address information classification determination unit 130 may determine the source address of the frame as the second classification MAC address information when the frame is at least one of a basic service set identifier (BSSID) frame, a beacon frame, and a probe response frame. The MAC address information classification determination unit 130 may classify the MAC address information by analyzing the characteristics of the frame. According to one embodiment of the present invention, the basic service set identifier (BSSID) frame is a frame having the MAC address of the access point 300, which is a 48-bit identifier that identifies the basic service area in the wireless LAN standard 802.11. That is, since the source address of the basic service set identifier frame is the MAC address of the access point 300, it can be determined as the second classification MAC address information.

According to one embodiment of the present disclosure, the beacon frame is transmitted periodically at the access point 300 to notify the presence of the access point 300 and enable the mobile device 200 to access the Wi-Fi network transmitted from the access point 300 . Therefore, since the source address of the beacon frame is the MAC address of the access point 300, it can be determined as the second classification MAC address information.

According to one embodiment of the invention, a probe response frame is a frame that is transmitted from the access point 300 to the mobile device 200. Since the source address of the probe response is the MAC address of the access point 300, it can be determined as the second classification MAC address information.

 When the frame is a probe request frame, the MAC address information classification determination unit 130 determines the source address of the frame as the first classification MAC address information, and if the destination address of the frame is the same as the destination address of the basic service set identifier frame , The source address of the frame may be determined as the first classification MAC address information. The probe request frame is a frame opposite to the probe response frame, and is a frame transmitted from the mobile device 200 to the access point 300. Therefore, since the source address of the probe request is the MAC address of the mobile device 200, it can be determined as the first classification MAC address information.

On the other hand, if the destination address of the collected frame, that is, the destination address is the MAC address of the basic service set identifier described above, it is the frame of the mobile device 200 to be transmitted to the access point 300, It can be determined by the classification MAC address information.

The storage unit 170 may store the first classification MAC address information or the second classification MAC address information. The storage unit 170 may store first classification MAC address information of the mobile device or second classification MAC address information which is a MAC address of the access point 300, a fixed device such as a beacon.

According to an embodiment of the present invention, when the MAC address information classification determination unit 130 classifies a MAC address of a frame into a MAC address of the mobile device 200, the information stored in the storage unit 170 may be used. For example, if the source address exists in the second classifier MAC address information stored in the storage unit 170, the destination address of the frame can be classified as the first classifier MAC address information. Likewise, if the destination address is present in the second classification MAC address information, the source address may be classified as the first classification MAC address information.

 The MAC address information classification determination unit 130 determines the transmission destination address of the frame as the first classification MAC address information when the address of the frame reception is included in the second classification MAC address information previously stored in the storage unit 130 . The frame transmitted / received between the access point 300 and the mobile device 200 may be transmitted / received via the second access point or the wireless signal amplifying device or the like have. At this time, since the passed device is also a fixed device, if a receiver RA address (RA) is present in the second classifier MAC address information stored in the storage unit 170, the frame transmission address (TA) ) As the first classification MAC address information.

The MAC address information classification determination unit 130 may classify the MAC address information by combining the classification conditions described above. According to one embodiment of the present invention, when the source address of a frame is a multicast address and the corresponding source address exists in the second classifier MAC address information stored in the storage unit 170, the destination address of the frame is classified into the first class It can be classified as MAC address information. In another embodiment, if it is obvious that a frame is a second response message frame address, such as a probe response frame, a base service set identifier frame, and a beacon frame, then the source address may be classified as first classifier MAC address information .

If the destination address is a fixed device in the process of analyzing the frame and MAC address characteristics, the MAC address information classification determination unit 130 may classify the source address into a first category Mac address information. In particular, if the destination address is a frame stored in the storage unit 170 as the second classification MAC address information, the source address of the corresponding frame may be classified as the first classification MAC address information.

The communication unit 160 may transmit the MAC address information to the server 400 and receive a response corresponding to the MAC address information from the server 400 when the MAC address information is the first classification MAC address information. The communication unit 160 may generate a message including the first classification MAC address information and an average of the reception intensity information or reception intensity information to be described later and transmit the message to the server 400. [ In this case, the message may be generated in proportion to the period of acquiring the frame in the frame acquiring unit 110, and may further include second classification MAC address information. If the communication with the server 400 is not connected, the communication unit 160 may store the message in the storage unit 170. When the communication is established, the communication unit 160 may transmit the generated message and the stored message to the server 400 have. A detailed description of the message is given below with reference to FIG.

The communication unit 160 receives the MAC address information, the device information corresponding to the MAC address information, the device type information corresponding to the MAC address information, the identifier of the MAC address information collection device, the message generation time, the transmission address, And transmits the generated message to the server 400. [0050]

7 is a diagram illustrating a format of a message according to an embodiment of the present invention.

Referring to FIG. 7, the identifier name 710 may indicate an identifier of the MAC address information collection apparatus 100. The time information 720 may be a time at which the communication unit 160 generates a message. The reason for determining the time in the communication unit 160 is that when the communication with the server 400 is not connected and when a message is received later, the time at which the actual frame is collected must be recorded. In order to record the collected time, the MAC address information collecting apparatus 100 preferably performs time synchronization with the server 400.

The destination address 730 may indicate the address of the server 400 that received the message. The MAC address 740 may represent the first classified Mac address information. The reception strength information 750 may indicate reception strength information corresponding to the MAC address 740. [ The message may represent the above-mentioned element and may repeat the above described elements of other mobile devices depending on the number of collected frames. In addition, the message may include device information corresponding to the MAC address information and device type information corresponding to the MAC address information, so that the server 400 can determine the MAC address of the device.

Hereinafter, an embodiment of processing and utilizing data in the MAC address information collecting apparatus or the server will be described with reference to Tables 1 to 5.

Table 1 shows an embodiment of the data structure generated by the MAC address information collection apparatus 100 or the server 400. [ At this time, the server 400 may generate a data structure based on the message received from the MAC address information collection device 100. [

Table 1. Data structure

The ID of the field of Table 1 may be set to identify the data by the serial number generated by the MAC address information collection apparatus 100 or the server 400. TS can be expressed in measured time (yyyy-mm-dd hour: minute: second) format. LOC represents an identifier of the MAC address information collection apparatus 100, and ADDR represents a MAC address of the mobile device. RSSI represents the average of the received strength information received in the message.

Table 2 shows an embodiment of a command for generating a list of MAC address information collected by the MAC address information collection device.

[Table 2]

Referring to Table 2, the MAC address information list generation command may display a list of MAC address information collected by the MAC address information collection apparatus 100.

Table 3 is an embodiment of the time base MAC address information list generation command.

[Table 3]

Referring to Table 3, the MAC address information list generation command may display a list of MAC address information collected by the MAC address information collection apparatus 100 from the current time to the previous hour. At this time, the time can be set so as to be added or subtracted.

Table 4 shows an embodiment of an instruction to detect a fixed device in the collected MAC address information.

[Table 4]

Referring to Table 4, the fixed device detection command classifies a device having a MAC address, which exists in all the time intervals of every 30 minutes, on all of the MAC address information collected 12 hours before the current time as a fixed device , And performs a function of finding a fixed device. In order to execute the command, a list of MAC address information collected in the last 30 minutes is generated. After that, it checks whether there is MAC address information collected up to 12 hours ago in the past 30-minute unit time, and counts the number. The threshold value of the counting is set, and if the number of counts in which the MAC address information exists is larger than the threshold value, the device having the corresponding MAC address information is classified as a fixed device. The process of Table 4 may be performed in the server 400 or the MAC address information collecting apparatus 100.

On the other hand, the server 400 receiving the message stores the first classification MAC address information or the second classification MAC address information included in the message in the database 410, and stores the stored first classification MAC address information or the second classification MAC And may transmit the address information to the communication unit 160 in response to the message. That is, the server 400 may classify the MAC address information together with the MAC address information collection device 100. [ The server 400 can also calculate the distance of the mobile device 200 from the MAC address information collection device 100 using the average of the reception intensity information or the reception intensity information included in the message, 160). At this time, the MAC address information collecting apparatus 100 performs at least one of the processes of Tables 1 to 4 to determine whether the collected MAC address information is the first classification MAC address information or the second classification MAC address information It can be judged. A further explanation will be given later with reference to Table 5.

The reception strength collection unit 150 may collect reception intensity information from the frame. The reception intensity collection unit 150 collects the received signal strength index (RSSI), which is one of the fields of the frame acquired by the frame acquisition unit 110. [ The reception intensity information may be used as one of the factors for calculating the distance of the mobile device 200 from the MAC address information collection device 100 in the server 400 and the distance calculation unit 140 described later. In addition, the reception intensity collection unit 150 may calculate an average of a plurality of reception intensity information collected by the same mobile device 200. [ This is because the same mobile device 200 can utilize the reception intensity information average to calculate the distance even if a plurality of frames are received.

Meanwhile, the communication unit 160 may transmit the reception strength information to the server 400 at predetermined intervals. The communication unit 160 may transmit the reception intensity information to the server 400 or may have a separate period for transmitting the reception intensity information corresponding to the period in which the frame acquisition unit 110 acquires the frame .

The distance calculation unit 140 may calculate the distance of the mobile device 200 from the MAC address information collection apparatus 100 using the first classification MAC address information and the reception intensity information. Although the server 400 calculates the distance of the mobile device 200 from the MAC address information collecting apparatus 100, the distance calculating unit 140 may perform the same operation of calculating the distance. An example of calculating the distance in the distance calculation unit 140 or the server 400 will be described below with reference to Table 5 on the basis of the method performed in the server.

Table 5 shows an embodiment of a command for calculating the distance between the MAC address information collection device 100 and the mobile device 200. [

[Table 5]

Referring to Table 5, the server 400 retrieves the MAC address of the mobile device 200 for which distance is to be sought from the first classification MAC address information, and refers to the received message to separate the time information and the reception intensity information As shown in FIG. Thereafter, the distance between the MAC address information collection device 100 and the mobile device 200 is calculated using the scaling coefficient according to an embodiment of the present invention. That is, the larger the value of the reception intensity information is, the closer the mobile device 200 is located to the MAC address information collection device 100. Also, the server 400 may calculate the distance between the MAC address information collection device 100 and the mobile device 200 and output the calculated distance as a 2D graph. According to one embodiment of the present invention, the graph can be generated using the pyplot function of the matplotlib library. The previously calculated distance or graph may be used to determine whether the collected MAC address information is the first classifier MAC address information or the second classifier MAC address information. For example, if the calculated distance is greater than the preset distance, the collected MAC address information may be determined as the first classification MAC address information corresponding to the mobile device.

The MAC address information collecting apparatus 100 using the Wi-Fi network of the present invention can collect the MAC address of the mobile device 200 in various manners without using any separate software or application. Also, by classifying and storing fixed devices, it can be utilized for detecting the MAC address of the mobile device. The mobile device or the fixed device can be easily classified as the data accumulates, and in particular, the data for the fixed device is accumulated, so that the MAC address of the new mobile device can be classified quickly and clearly.

Also, as the WiFi network is popularized, the MAC address information collection device 100 can be widely used in shops, shops, and the like where the access point 300 is installed. It is possible to acquire the MAC address of the customer's mobile device via the MAC address information collection device 100 to acquire the movement route in the store, and calculate the residence time and the re-visit rate. Based on these customers' MAC address information, they can be used as marketing information such as various service provision and management.

In addition, if customers obtain their consent to collect and use personal information, it is possible to provide more personalized services and collect sophisticated marketing information.

The configuration and operation of the MAC address information collecting apparatus 100 have been described above. Hereinafter, a MAC address information collection method will be described with reference to FIGS. 3 to 6B. The MAC address information collection method can perform the same operation as the MAC address information collection apparatus.

3 is a flowchart of a method of collecting MAC address information according to an embodiment of the present invention.

Referring to FIG. 3, the step of collecting wirelessly transmitted frames (S310) may collect frames transmitted and received in the Wi-Fi network transmitted from the access point 300 in the frame obtaining unit 110. FIG. In the Wi-Fi network, 14 channels having respective bands are formed, and data communication is performed for each channel. At this time, the frame obtaining unit 110 may collect frames from any one of the 14 channels.

In operation S320, the MAC address information extraction unit 120 may extract the MAC address information from the header of the frame. The MAC address information includes a source address (SA) as a MAC address of a device at which a frame starts, a destination address (Da) as a MAC address of a device that finally receives a frame, a wireless device A receiver address (RA), which is a MAC address identifying a wireless device receiving the frame, and a basic service set identifier (MAC address) of the access point 300, (BSSID) may be included.

(S330) of determining the MAC address information as the first classifying MAC address information corresponding to the mobile device or the second classifying MAC address information corresponding to the fixed device based on the frame is performed by the MAC address information classifying and determining unit 130 Classify address information. When the MAC address information of the mobile device such as a smart phone or a PDA is detected from the transmission destination or the destination address in the frame field, the MAC address information classification determining unit 130 classifies the MAC address information into the first classification MAC address information, When MAC address information of a fixed device such as an access point, a PC, a router, or a beacon is detected from a transmission destination or a destination address in a frame field, the MAC address information is classified into second classifying MAC address information.

As a result of classifying the MAC address information, the classified first MAC address information is obtained (S340). If it is the second classification MAC address, it is stored in the storage unit 170 (S350). At this time, the first classification MAC address information may also be stored in the storage unit 170.

If the MAC address information is the first classification MAC address information, the step of transmitting the MAC address information to the server transmits the MAC address information to the server 400 (S360). The communication unit 160 receives the MAC address information, the device information corresponding to the MAC address information, the device type information corresponding to the MAC address information, the identifier of the MAC address information collection device, the message creation time, the transmission address, And transmits the MAC address information to the server 400 together with the MAC address information. The step of receiving a response (S370) receives a response corresponding to the MAC address information from the server 400. [ The server 400 can obtain the distance of the mobile device 200 from the MAC address information collection device 100 using the average of the reception intensity information or the reception intensity information included in the message and transmit the result to the communication unit 160 Can

The MAC address information determination step may classify the MAC address information in various ways, and will be described below with reference to FIGS. 4 to 5C.

4 is a diagram illustrating an embodiment of classifying a MAC address according to a MAC address characteristic according to an embodiment of the present invention.

Referring to FIG. 4, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. Thereafter, the MAC address information classification determination unit 130 determines whether the MAC address information includes at least one of a broadcast address and a multicast address (S321). If at least one of the broadcast address and the multicast address is included in the detected MAC address information, the MAC address information may be determined as the second classification MAC address information in operation S330. Since the broadcast address is FF: FF: FF: FF: FF: FF: FF, it can be determined that the broadcast address is not the MAC address of the mobile device, and can be classified into the second category MAC address information. The multicast address is an address assigned from 01: 00: 5: 00: 00: 00 to 01: 00: 5E: 7F: FF: FF in IPv4 and assigned as 33: 33: XX: XX: XX: XX in IPv6. Address. At this time, 33:33 is a fixed address, and XX: XX: XX: XX is an address that can be changed according to the group. Since the multicast address also has the specified MAC address, it can be determined that the multicast address is not the MAC address of the mobile device and can be classified into the second category MAC address information.

5A is a diagram illustrating an embodiment of a MAC address classification according to a frame characteristic according to the first embodiment of the present invention.

Referring to FIG. 5A, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. In step S322, the MAC address information classification determination unit 130 determines whether the collected frame includes at least one of a basic service set identifier (BSSID) frame, a beacon frame, and a probe response frame. (BSSID) frame, a beacon frame, and a probe response frame, the source address of the frame may be determined as the second classification MAC address information (S322). Since the source address of the basic service set identifier frame is the MAC address of the access point 300, it can be determined as the second classification MAC address information. Since the source address of the beacon frame is the MAC address of the access point 300, it can be determined as the second classification MAC address information. Since the source address of the probe response is the MAC address of the access point 300, it can be determined as the second classification MAC address information.

5B is a diagram illustrating an embodiment of MAC address classification according to a frame characteristic according to the second embodiment of the present invention.

Referring to FIG. 5B, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. Thereafter, the MAC address information classification determination unit 130 determines whether the collected frame is a probe request frame (S323). The probe request frame is a frame transmitted from the mobile device 200 to the access point 300. Therefore, since the source address of the probe request is the MAC address of the mobile device 200, it can be determined as the first classification MAC address information.

5C is a diagram illustrating an embodiment of MAC address classification according to a frame characteristic according to the third embodiment of the present invention.

Referring to FIG. 5C, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. Thereafter, the MAC address information classification determination unit 130 determines whether the destination address of the collected frame is the same as the destination address of the basic service set identifier frame (S324). If the destination address of the collected frame is the same as the destination address of the basic service set identifier frame, the source address of the frame may be determined as the first classification MAC address information.

6A is a diagram illustrating an embodiment of classifying a MAC address using a stored MAC address according to an embodiment of the present invention.

Referring to FIG. 6A, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. In step S325, the MAC address information classification determination unit 130 determines whether the RA address RA of the frame is included in the second classification MAC address information previously stored in the storage unit 170. If the received routing address is included in the second classification MAC address information stored in the storage unit, the transmission destination address TA of the frame may be determined as the first classification MAC address information.

FIG. 6B is a diagram illustrating an embodiment for collecting reception strength according to an embodiment of the present invention. FIG.

Referring to FIG. 6B, the frame is collected in step S310, and the MAC address information of the frame collected in step S320 is extracted. Then, the reception strength collection unit 150 collects reception intensity information. The reception strength collection unit 150 collects Received Signal Strength Index (RSSI), which is one of the fields of the frame. The reception intensity information may be used as one of the factors for calculating the distance of the mobile device 200 from the MAC address information collection device 100 in the server 400 and the distance calculation unit 140. [ In addition, the reception intensity collection unit 150 may calculate an average of a plurality of reception intensity information collected by the same mobile device 200. [ This is because the same mobile device 200 can utilize the reception intensity information average to calculate the distance even if a plurality of frames are received.

After the reception intensity collection unit 150 collects reception intensity information, the MAC address information classification determination unit 130 determines the classification of the MAC address information using the above-described methods (S330). The distance of the mobile device 200 may be calculated from the MAC address information collection device 1100 using the reception intensity information collected by the distance calculation unit 140 at step S331. The operations performed by the distance calculation unit 140 are the same as those described in Table 5 above.
