WLAN Specifications
* “Wi-Fi based” indicates that the interconnectivity test of the organization which guarantees the interconnectivity of
wireless LAN (Wi-Fi Alliance) has been passed.
** The communication ranges shown above will increase or decrease depending on factors such as number of walls,
reflective material, or interference from external RF sources.
*** Encryption with network key (WEP) is performed using the above number of bits, however, users can set 40 bits/
104 bits after subtracting the fixed length of 24 bits.
**** Depending on practical environments, the allowable number of computers to be connected may be decreased.
