Terminology Wireless Channel It is necessary to divide frequency spectrums into some Wireless channels for Wireless communication, and to tune to the same channel between Wireless equipment. If you use the same channel on the same floor, and there are some Wireless LANs that have a different ESSID for each, the communication speed may become slow. In that case, using different channels for each Wireless LAN is effective, which lowers a possibility of mutual interference between Wireless LANs. MAC address (Media Access Control Address) MAC address is a physical address for every network interface. The MAC address consists of 6-byte hex number. The first 3 bytes are a Vendor ID controlled and assigned by IEEE. The last 3 bytes are controlled and assigned by the manufacturers of network interface (no duplication of MAC address). Therefore, MAC address is a unique physical address in the world. Ethernet sends and receives frames on the basis of MAC address. IEEE802.11b It is one of the wireless LAN standards set by 802 committee that formulates a standard of the LAN technology in IEEE (the Institute of Electrical and Electronics Engineers).By using the 2.4GHz licensefree frequency band, you can perform communication at a speed of 11 Mbps at the maximum. IEEE802.11g By using the 2.4GHz license-free frequency band as well as IEEE802.11b, you can perform communication at a speed of 54 Mbps at the maximum, which is about 5 times the speed of IEEE802.11g. Moreover, there is an upward compatibility with IEEE802.11b. IEEE802.11n It is a next-generation Wireless LAN standard that is being developed with the aim of producing the maximum transmission speed of 600Mbps by using the technology called MIMO, combines multiple channels and performs transmission. It is being designed to have a compatibility with IEEE802.11b and IEEE802.11g.

Wireless Channel
It is necessary to divide frequency spectrums into some Wireless channels for Wireless
communication, and to tune to the same channel between Wireless equipment. If you use the same
channel on the same floor, and there are some Wireless LANs that have a different ESSID for each, the
communication speed may become slow. In that case, using different channels for each Wireless LAN
is effective, which lowers a possibility of mutual interference between Wireless LANs.
MAC address (Media Access Control Address)
MAC address is a physical address for every network interface. The MAC address consists of 6-byte
hex number. The first 3 bytes are a Vendor ID controlled and assigned by IEEE. The last 3 bytes are
controlled and assigned by the manufacturers of network interface (no duplication of MAC address).
Therefore, MAC address is a unique physical address in the world. Ethernet sends and receives frames
on the basis of MAC address.
Terminology
IEEE802.11b
It is one of the wireless LAN standards set by 802 committee that formulates a standard of the LAN
technology in IEEE (the Institute of Electrical and Electronics Engineers).By using the 2.4GHz license-
free frequency band, you can perform communication at a speed of 11 Mbps at the maximum.
IEEE802.11g
By using the 2.4GHz license-free frequency band as well as IEEE802.11b, you can perform
communication at a speed of 54 Mbps at the maximum, which is about 5 times the speed of
IEEE802.11g. Moreover, there is an upward compatibility with IEEE802.11b.
Wi-Fi Alliance
(Formerly Name: WECA (Wireless Ethernet Compatibility Alliance))
It is an organization that aims to promote the spread of Wireless LAN, and it guarantees the
interoperability of products that meet the Wireless LAN standard.
IEEE802.11n
It is a next-generation Wireless LAN standard that is being developed with the
aim of producing the
maximum transmission speed of 600Mbps by using the technology called MIMO, combines multiple
channels and performs transmission. It is being designed to have a compatibility with IEEE802.11b
and IEEE802.11g.
Wi-Fi (Wireless Fidelity)
It is a brand name, showing that the interconnectivity between wireless LANs is certified by the Wi-Fi
Alliance (formerly WECA). The products that passed the Wi-Fi Alliance interoperability test are given
the certification of
‘Wi-Fi certified’ and permitted to use the Wi-Fi Logo.The products that have Wi-Fi
