Troubleshooting Preparations Parts and Controls Basic Operations Connections Other Operations Apps Announcements © 2012 Sony Corporation SGPT12/SGPT13 Series Back to Top Search Notes on Using the Wi-Fi Function Use of Wi-Fi devices may be restricted by local regulations in some countries or regions. Wi-Fi devices work on the 2.4 GHz band, which is used by a variety of devices. Wi-Fi devices therefore use technology to minimize radio interference from other devices that use the same band. However, radio interference may still cause slower data transfer speeds, reduce communications range or cause communications failure. If both the Bluetooth function and the 2.4 GHz Wi-Fi function of your tablet device are enabled, interference may occur and cause slower data transfer speeds or other problems. To communicate via Wi-Fi while traveling, you may need to contract with a Wi-Fi connection service provider. Data transfer speed and communications range may vary depending on the following conditions: Distance between devices Presence of obstacles between devices Device configuration Signal conditions Surrounding environment (wall material, etc.) Software in use Communications failure may occur in some signal conditions. The data transfer rate noted in the specifications is the theoretical maximum, and it may not reflect actual data transfer rate. Actual data transfer speed may not be as fast as the speed displayed on your tablet device. Communications is not available between the 2.4 GHz and 5 GHz Wi-Fi frequency bands. The data transfer rate for IEEE 802.11g and IEEE 802.11n (2.4 GHz) devices may be affected by interference when those protocols are used with IEEE 802.11b products. Also, products using IEEE 802.11g and IEEE 802.11n automatically lower the transfer rate to maintain compatibility with IEEE 802.11b products. When the data transfer speed is not as fast as expected, changing the wireless channel on the Wi-Fi router may increase the speed. Only use Wi-Fi indoors when using it with IEEE 802.11a/n (5 GHz).
