Socket's SDIO 56K Modem Card V.92 offers business travelers a reliable option for Internet access via mobile devices such as Pocket PCs or Tablet computers through common analog telephone lines, especially in areas where Wi-Fi networks are absent. It uses an SDIO (Secure Digital Input/Output) interface to connect to the mobile device. Its V.92 modem technology boosts upstream data rates between the user and Internet Service Provider (ISP) to reduce upload time for large files and email attachments. The Modem-On-Hold enables incoming or outgoing calls without disconnecting. Quick Connect, a V.92 feature, shortens the time it takes to make a connection by saving phone line characteristics for later use. The modem also features link and data LEDs and an internal speaker for monitoring connection status.
