FAQ- information on how to solve common issues which may arise while using your device.
- 802.11b - The 802.11b standard features an 11 Mbps wireless connection that uses the direct-sequence spread spectrum (DSSS) technology in a non-licensed 2.4 GHz radio band, with a protection in the form of WEP encryption. 802.11b networks are also called WiFi networks.
- 802.11g – The 802.11g standard features an 54 Mbps wireless connection that uses the direct-sequence spread spectrum (DSSS) technology and OFDM modulation in a non-licensed 2.4 GHz radio band, backward compatible with IEEE 802.11b devices, with a protection in the form of WEP encryption.
- 802.11n – The 802.11n standard was developed on the basis of the existing 802.11 standards by adding the multiple-input multiple-output (MIMO) function. The MIMO uses multiple transmitting and receiving antennas to reach a higher bandwidth in spatial multiplexing and an increased signal range by using spatial variability, probably by encoding schemes such as Alamouti. Enhanced Wireless Consortium (EWC) was established to support a fast development of the IEEE 802.11n standard and to promote the interoperability of new-generation wireless WLAN devices.
- Sieć typu Infrastructure – The Infrastructure network is a group of computers or other devices equipped with wireless network cards, interconnected to form a wireless 802.11 LAN. In the Infrastructure mode, the wireless devices communicate with one another and with the wired network via an access point. The wireless Infrastructure network linked with a wired network is called Basic Service Set (BSS). A group of two or more BSSs in a single network is called Extended Service Set (ESS). The Infrastructure mode is applied on the scale of whole enterprises, where it is necessary to interconnect wired and wireless networks.
- SSID (Service Set Identification) - It is an alphanumeric code consisted of up to 32 characters, which identifies a wireless LAN. To be able to communicate within a single wireless network, all devices must be configured with the same SSID. It is a typical configuration parameter for a wireless PC card.
- WEP (Wired Equivalent Privacy) – A data security mechanism based on a 64-bit, 128-bit or 152-bit shared-key algorithm, defined in section “IEEE 802.11 standard”. Access to a WEP network requires an access key. The key has the form of a character string created individually by the user. When using a WEP, you must define the encryption level. The type of encryption is determined by the length of the key. A 128-bit encryption requires the key to be longer than for a 64-bit encryption. The key is created by entering a character string in the sixteen-character system (characters: 0–9 and A–F) or characters from the American Standard Code for Information Interchange (ASCII). The ASCII code allows for entering a key that is easy to remember. For the network purposes, the ASCII string is converted to the sixteen-character format. You can define four different keys and change them easily.
- Wi-Fi – The trade name of the wireless 802.11b standard, given by the Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), which is an organisation involved in industrial standards and promoting the compatibility of all 802.11b devices.
- WLAN (Wireless Local Area Network) – A group of computers and associated devices wirelessly communicating with one another, including a locally restricted group of users.
- WPA (Wi-Fi Protected Access) – A wireless network security protocol, which uses the Temporal Key Integrity Protocol (TKIP) encryption and can be used together with a RADIUS server.
