Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0048] (Embodiment 1)

[0049] figure 1A schematic block diagram showing a hardware configuration of a wireless LAN card for realizing a wireless LAN according to an embodiment of the present invention is shown.

[0050] In this figure, the wireless LAN card 10 has a bus IF11 of an interface circuit for connecting to a bus for computer peripheral equipment (not shown), and is connected to a CPU 12 that centrally controls the wireless LAN card 10 . The CPU 12 is connected to an internal bus 13 , and the internal bus 13 is connected to a RAM 14 and a ROM 15 . The CPU 12 executes predetermined calculation processing while appropriately utilizing the memory area of ​​the RAM 14 based on firmware or data recorded in the ROM 15 .

[0051] The bus 13 is connected to two sets of physical layer loops 20 . The physical layer circuit 20 is respectively, a MAC circuit 21, a bas...

Abstract

The disadvantage of the conventional wireless LAN is that it cannot increase the transmission speed until the standard is revised. Even though a proprietary technology can be developed, it would be inconvenient for users because it lacks generality. The wireless LAN card 10 containing two sets of physical layer circuits 20a and 20b corresponding to two sets of wireless LAN standards (IEEE 802.11aand IEEE 802.11b) is controlled by the CPU 12. By using these two sets of wireless LAN standards, it is possible to increase the amount of data transmission per unit time while maintaining the standards. Moreover, it is also possible to realize high-speed data transmission easily by using more than two wireless LAN standards simultaneously in parallel.

Description

technical field [0001] The present invention relates to a wireless LAN, a data receiving and sending method of the wireless LAN and a medium for recording data sending and receiving control programs. Background technique [0002] In the field of wireless LAN, various standards including transmission speed exist. With the development of the times, the requirements of high speed make the relevant standards are constantly being revised. [0003] In addition to the technical aspects, there are various issues in standard revision. Just being technically feasible does not mean that high-speed wireless LAN can be provided. [0004] Conventionally, this kind of wireless LAN is known to transmit and receive data using any one of a plurality of standards. [0005] In the above-mentioned conventional wireless LAN, even if higher-speed data transmission and reception are to be performed, the standards must be revised. Also, although a unique technique can be used, there is a problem...
