Configuration tasks needed to form a wireless LAN are performed using a simple method while increasing security during configuration. In a wireless network configuration system GHincluding an encryption key setting system LH, where an access pointdetermines after the power thereto is turned ON that configuration for connection to a wireless LAN has not yet be carried out, the access pointactivates a restricted receiving mode in which only an initial configuration packet is accepted. A terminalthat has sent an initial configuration packet and the access pointthat has received such initial configuration packet while the restricted receiving mode is active each create an identical WEP key with reference to the data on a CD-ROMor the data in a ROM, respectively, and set and register the created WEP key in itself.

The present invention provides a LAN devicehaving an internal function of controlling communication. A management representative of the LAN devicesets a protocol applicable for communication with regard to each of MAC addresses or IP addresses allocated to transmitter terminals and each of IP addresses allocated to receiver terminals. The LAN device transmits data in the case of the protocol applicable for communication, while not transmitting data in the case of any protocol inapplicable for communication.

To provide a technique for analyzing radio wave condition affording improved accuracy of discrimination of radio wave propagation condition on a per-channel basis. Analyzer devicefor analyzing the condition of radio waves used for wireless LAN communications comprises a reception portionfor receiving radio signals in a plurality of frequency bands; a first strength sensing portionfor sensing the field strength RSSof the center frequency band on a per-channel basis from a received radio signal; a despreading portionfor despreading the received radio signal; a second strength sensing portionfor sensing the field strength RSSIof the center frequency band on a per-channel basis from the despread radio signal; a discriminating portionfor discriminating radio wave condition by cross-checking RSSIand RSSIon a per-channel basis; and a display portionfor displaying the discriminated radio wave condition.

Analyzing technology of radio wave in wireless information communication

An access point () for providing a wireless LAN, comprising: a communication unit () that performs a wireless LAN communication; a status determination unit () that, constituted by separate from hardware constituting the communication unit (), determines radio wave statuses on each of a plurality of channels; a wireless communication control unit () that selects, on the basis of the determined radio wave statuses, a channel use for the wireless LAN communication; and a communication CH switch unit () that switches from a channel currently performing the wireless LAN communication to the selected channel.

The present invention prevents a third party's impersonation while wireless communication is established for security setting. An access point, which performs a security setting process for wireless communication with a wireless LAN terminal by means of wireless communication, receives a start instruction for the security setting process and wirelessly receives start instruction data that indicates the start of the security setting process. The security setting process is not performed if the start instruction data is received before the receipt of the start instruction. The security setting process is performed if the start instruction data is not received before the receipt of the start instruction.

Security setting system

The conventional wireless LAN system has the difficulties in limiting the extent to which network services are provided simply by controlling the intensity of radio wave. When the master unitdetects a mobile wireless terminal in its communication area (in step S), it inquires of a plurality of slave unitsandif they are ready for communication with the mobile wireless terminal (in step S). The master unit determines whether or not to provide network services to the mobile wireless terminal according to the combination of readiness for communication between each the slave unitsandand the mobile wireless terminal (in steps Sand S).

The registering work of a wireless LAN terminal and a wireless LAN access point has been troublesome especially to beginners. According to the wireless LAN communication system of this invention, the client terminal judges the necessity of registering the communication profiles, and if necessary, executes the register processing with the wireless LAN access point, which simplifies the registering work by the user. Here, the system requires the wireless LAN access point to switch the normal mode into the register request-accepting mode, which makes it possible to prevent the register processing from being executed with unintentional client terminals. Therefore, it is possible to provide a wireless LAN communication system that facilitates the registering work and achieves the security at a satisfactory level.

System and method for establishing a wireless LAN communication

Access pointstarts the WEP key setting process by working registration buttonA of remote controller. The range reached by the electric waves transmitted from access pointis changed from wireless communication area ARwhich is the normal range to security communication area MRwhich is a narrower range. After that, access pointdelivers the used WEP key to terminal, and after confirming delivery, registers the MAC address of terminal. Terminalsets the delivered WEP key itself. As a result, it is possible to realize with a simple method the new addition of terminals used for a wireless LAN while preventing leaking of data that represents the encryption key.

The present invention addresses a problem that switching antennas along with an unexpected variation of a received electrical field strength brings about a loss over a long period of data transmission. According to a wireless LAN transceiver in which the present invention is implemented, when a data throughput attained by an application layer poses no problem, switching antennas is disabled. Consequently, the data throughput can be kept satisfactory. Namely, since whether the antennas are switched is not determined with an unexpected variation of an RSSI signal or an error rate in a lower layer, unnecessary switching of the antennas can be prevented. A loss derived from the switching of the antennas can be minimized over a long period of time.

Wireless LAN transceiver and wireless LAN transmitting/receiving method

To protect a password from leakage, it is necessary to change it frequently, which is troublesome and difficult to be done realistically. According to the present invention, an encrypted access code is stored in a transportable and nonvolatile memory on the part of a computer to be remotely accessed. When a user actually carries the nonvolatile memory to plug it into a computer remotely accessing, remote access is established between the computer to be remotely accessed and the computer remotely accessing.
