Description

Wireless LAN Signal Meter {WIRELESS LAN SIGNAL TESTER}

The present invention relates to a wireless LAN signal measuring instrument, and more particularly, to allow a user to quickly and easily check whether or not to use the wireless LAN service at the current location of the user without attempting to access the wireless LAN. The signal relates to an instrument.

Wireless LAN refers to a network system that wirelessizes a client from a hub / access point to a client, and installs an access point so that service subscribers can use the Internet wirelessly anytime and anywhere. The service business is called a hotspot business. At present, the hotspot service has been continuously activated around the downtown area, but the hotspot service area is still very limited. In addition, unlike the base station of the cellular phone, the access point of the wireless LAN due to its technical and legal limitations can not stand a lot of antennas, there is a limit to minimize the radio shading area. The technical and legal limitations mean that the wireless LAN has a wide frequency bandwidth, and out of the 13 channels currently serving wireless LAN, only three channels can be used by an adjacent access point at a time. 10mW, which is limited to the output of only one tenth to one tenth of a cell phone, implies the current law limitation that local access points must be installed to cover a small area. Even if the area is expanded, there is still a shaded area that is difficult to provide a wireless LAN service.

Recently, the demand for wireless LAN service is increasing due to mobile users using notebook computers, personal digital assistants (PDAs), etc., due to the ease of mobile LAN installation and installation. In addition, fixed users have a tendency to apply a wireless LAN system that is easy to install due to many inconveniences such as difficulty in changing the layout of an office when using a wired LAN.

However, due to the limitation of the wireless LAN service area, the WLAN user should try to connect by turning on a terminal such as a computer or a PC in order to find out whether his current location is a service area of the wireless LAN. There is a problem that the inconvenience is severe, and there is a problem that there is no means to easily check whether the WLAN radio reception before applying the WLAN system in the office.

In addition, since the technology standards that WLANs are being followed are rapidly being replaced, devices capable of measuring radio wave signals of WLANs are currently a technical standard IEEE (Institute of Electrical and Electronics Engineers) 802.11b In addition, there has been a technical problem of being compatible with WLANs complying with other technical standards.

The present invention has been devised to solve the above-mentioned conventional problems, and it is possible to easily and quickly check whether the WLAN user can normally use the WLAN service at the current location without attempting to access by using various terminals. The purpose is to provide an apparatus.

In particular, by using a wireless LAN card as a receiver of the WLAN signal measuring device of the present invention, there is another object to provide a wireless LAN signal measuring instrument that is compatible with a wireless LAN complying with other technical standards.

The radio wave information processing unit 30 is composed of a microcomputer, and in detail, is composed of an input circuit 310, a main controller 320, an output circuit 330 and the like.

The main controller 320 is a control device for displaying the information on the received radio signal on the radio wave information display unit 40, read-only memory (ROM), static random access memory (SRAM), MPU ( Micro Processing Unit). The ROM stores input data such as a predetermined program and an image, and the SRAM is used as a temporary memory when converting and calculating data stored in the ROM, and is used in serial communication with a computer. The MPU outputs a signal so that predetermined radio wave information can be displayed on the radio wave information display unit 40 through the output circuit 330 after arithmetic processing the data stored in the memory.

The input circuit 310 is connected to an output terminal of the radio signal input unit 20 to receive a predetermined signal, and the output circuit 330 is connected to the radio wave information display unit 40 to provide the radio wave information display unit 40.

The power lamp 410 emits light when the power is turned on to indicate an off / on state of the power.

The radio wave intensity lamp 420 indicates the degree of radio wave intensity by causing the flicker to increase as the radio wave intensity increases. In addition, when the Yagi antenna is mounted to have a high sensitivity in the direction of the radio wave, the direction of the radio wave may be identified since the speed of blinking of the radio wave intensity lamp 430 varies according to the direction of the WLAN signal meter.

The access lamp 420 indicates the quality of the WLAN connection by emitting light when the quality of radio waves is good or by causing the flickering to accelerate. In this case, if the intensity of the radio wave is high, the quality of the connection will generally be high, but if there is a disturbing factor such as an electronic device using a frequency band such as the WLAN to be used around the terminal, the connection quality of the WLAN may be deteriorated. In addition, it is preferable to implement so that the connection quality of the wireless LAN radio waves can be displayed.

The power switch 4 can be turned on only when you want to use the WLAN signal meter can reduce the consumption of unnecessary power.

In addition, one side of the body is provided with a battery insertion unit 510 that can insert a battery for supplying a voltage to the WLAN signal meter.

It is preferable to implement the display quality of the wireless LAN radio wave separately from the radio wave strength as described above.

The channel display unit 460 is a portion for displaying the channel of the wireless LAN signal currently being measured, it is preferable to use a light emitting diode or a liquid crystal display.

The channel switch 6 allows the user to select a WLAN radio channel to be measured among the 13 WLAN channels currently provided for service, and the channel selected by the channel switch 6 is displayed on the channel display unit 460. .

The test switch 8 is used to perform a self test on whether the WLAN card 10 is well connected to the WLAN signal meter. When the test switch 8 is turned on after the wireless LAN card is inserted into the card insertion unit 210, the connection state is displayed. When the connection is normally performed, the power lamp 410, the connection lamp 420, and the electric wave intensity lamp ( 430 may emit light at the same time.
