Problems solved by technology

[0006] Especially in the case of wireless communication using the above-mentioned MIMO method, since reflected waves are used together with direct waves during wireless communication, the correlation between the electric field strength and the communication status level is further reduced
Conventionally, insufficient efforts have actually been made to properly notify the user of the communication status level in wireless communication using the MIMO method.

[0044] E. Variations:

[0045] A. The first embodiment:

[0046] figure 1 It is a schematic diagram showing the configuration of a wireless LAN system as an embodiment of the present invention. This wireless LAN system 1000 includes a wireless terminal device 110 as a wireless LAN slave, a terminal PC 120, and an access point 200 as a wireless LAN master. The wireless terminal device 110 and the access point 200 are wireless relay devices that wirelessly transfer communications between devices and networks connected to them. The wireless terminal device 110 is connected to the terminal PC 120, and the access point 200 is connected to the Internet IN. The terminal PC 120 can connect to the Internet IN through wireless communication between the access point 200 and the wireless terminal device 110 .

[0047] Here, the wireless terminal device 110 includes two antennas 11 , 12 , and the access point 200 also includes two antennas 21 , 22 . The wireless terminal device 110 and...

Deformed example 1

[0097] In the above-described embodiments, a part of the configuration realized by software may be replaced by hardware, or vice versa, a part of the configuration realized by hardware may be replaced by software. For example, part of the functions of the transmission signal generation unit 134 and the reception data generation unit 135 may be performed by the transmission and reception circuits 111 and 112 .

Deformed example 2

[0099] In the above-mentioned embodiment, the wireless terminal device 110 has two antennas 11 and 12 respectively. However, the wireless terminal device 110 may include n (n is an integer equal to or larger than 2) antennas. In this case, the wireless terminal device 110 divides the transmission data to generate n sequences of transmission signals, and transmits them from each of the n antennas. In addition, similarly, the access point 200 may include m (m is an integer greater than or equal to 2) antennas.

Abstract

The invention provides a wireless terminal device, a wireless communication system, and a method of notifying the communication status level. An object of the invention is to provide the user with enhanced convenience in wireless communications by using an MIMO technology to properly notifying communication status level. The wireless terminal device 110 for communicating with an access point 200 through the MIMO protocol, comprising a throughput measurement module 132 for measuring the throughput during the communication with the access point 200, and an indicator unit 13 for notifying the user of the level of the status of communication with the access point 200 according to the result of measurements obtained by the throughput measurement module 132.

Description

technical field [0001] The present invention relates to a wireless LAN using wireless communication. Background technique [0002] In a wireless LAN, data is transmitted and received by radio waves between an access point (wireless LAN master unit) connected to the network side and a wireless terminal device (wireless LAN slave unit) such as a wireless LAN card (Patent Document 1, etc. below) . As a wireless LAN communication method, a MIMO (Multi Input Multi Output: Multiple Input Multiple Output) method is known. [0003] In wireless communication using the MIMO method, a plurality of antennas are provided in each of the wireless LAN main unit and the wireless LAN slave unit, and radio waves are transmitted and received through each antenna, thereby achieving high-speed and stable communication. More specifically, on the transmitting side, a plurality of signals generated by dividing the transmission data are simultaneously transmitted from each antenna within the same f...
