LifeBook T4200 Series Tablet PC - Appendix A Specifications Item Type of network Transfer rate Active frequency Number of channels Typical operating distances** Security Maximum recommended number of computers to be connected over wireless LAN (during ad hoc connection) Specifications Conforms to IEEE 802.11a/802.11b/g (Wi-Fi based)* (Automatic switching) IEEE 802.11a/g: 54 Mbps maximum data rate IEEE 802.11b: 11 Mbps maximum data rate 802.11b/g: 2400~2473 MHz 802.11a: 4900 ~ 5850 MHz 802.11a: 8 independent channels 802.11b/g: 11 channels, 3 non-overlapping channels 802.11a: 40 ft. (12 m) @ 54 Mbps; 300 ft. (91 m) @ 6 Mbps 802.11b: 100 ft. (30 m) @ 11 Mbps; 300 ft. (91 m) @ 1 Mbps 802.11g: 100 ft. (30 m) @ 54 Mbps; 300 ft. (91 m) @ 1 Mbps Encryption Types - WEP, TKIP, AES*** WPA 1.0 compliant Encryption Keylengths Supported: 64 bits, 128 bits, and 152 bits (Using AES encryption only) 802.1x/EAP CCX 1.0 compliant 10 units or less**** * "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. 108
