Glossary
- AES
- A security algorithm; prevents decryption by dividing the security key (password) and by repeatedly performing substitutions and permutations. It is more secure than TKIP.
- Channel bandwidth
- A bandwidth occupied within a Wi-Fi frequency band. 20 MHz is recommended; 40 MHz (IEEE802.11n/ac) and 80 MHz (IEEE802.11ac) are optionally available for higher data rates.
- IEEE802.11a
- A wireless networking standard using the 5 GHz band; enables communication at a maximum transfer rate of 54 Mbps.
- IEEE802.11ac
- Also known as Wi-Fi 5. It is a wireless networking standard using the 5 GHz band; enables communication at a maximum transfer rate of 6.93 Gbps when used with a maximum channel bandwidth of 80 MHz.
Compatible with IEEE802.11n in the 5 GHz band as well as IEEE802.11a.
- IEEE802.11b
- A wireless networking standard using the 2.4 GHz band; enables communication at a maximum transfer rate of 11 Mbps.
- IEEE802.11g
- A wireless networking standard using the 2.4 GHz band; enables communication at a maximum transfer rate of 54 Mbps.
Compatible with IEEE802.11b.
- IEEE802.11n
- Also known as Wi-Fi 4. It is a wireless networking standard using the 2.4 GHz band and 5 GHz band; enables communication at a maximum transfer rate of 600 Mbps when used with a maximum channel bandwidth of 40 MHz.
Compatibility with IEEE802.11b/g and IEEE802.11a is achieved in the 2.4 GHz band and in the 5 GHz band, respectively.
- Network
- A system to exchange information between devices (such as computers) by connecting them to each other. The Internet is a type of network.
- Network name (SSID)
- A name to identify a wireless router used in a wireless network.
- Router
- A device that plays the role of bridging or connecting the communication between devices (computers, printers, etc.) on the network.
- TKIP
- A security protocol; periodic renewal of the security key (password) prevents decryption by a third party.
- USB
- A standard to connect peripherals (such as printers) to computers and other devices.
- Wi-Fi
- A brand name given only to products that have passed Wi-Fi Alliance interoperability tests. Your printer is a Wi-Fi certified product. It may also refer to a LAN (local area network) that does not require cables.
- Wireless Direct
- A method for connecting the printer to a computer or other devices directly without using a wireless router.
- Wireless router
- A device that acts as a bridge when establishing a wireless network.
- WPA
- A security protocol for wireless networks, with improved security compared to WEP.
- WPA2
- A security protocol for wireless networks, with improved security compared to WPA.
- WPA3
- A security protocol for wireless networks. It is a new version of WPA2. High security can be achieved regardless of the length of the security key (password).
- WPS
- A standard with which wireless device connections and security setting can be established easily. Push button method and PIN code method are available. WPS stands for Wi-Fi Protected Setup.
