working of wirwed modem

A Pocket PC can connect to the Internet via a wired modem in one of two ways. If the Pocket PC has a Bluetooth Internet connection, it can connect to a wired modem that has Bluetooth technology or a Bluetooth modem connected to it. If the Pocket PC has WiFi capabilities, it can connect to any wired modem that has a wireless router connected to it.
Connecting to a Wired Modem with Bluetooth
Pocket PCs with Bluetooth capability must first have the Bluetooth connection enabled. If the modem has Bluetooth built in, this should also be enabled. If the modem lacks Bluetooth, a seperate Bluetooth router can be purchased and connected via ethernet cable to broadband modems or directly to a dial-up modem with a standard phone line.If a modem has Bluetooth or a Bluetooth router connected but the Pocket PC lacks Bluetooth, a Bluetooth CompactFlash Type 2 adapter card can be purchased, giving the Pocket PC instant Bluetooth connectivity. The Pocket PC will discover the Bluetooth modem connection and connect to it.
Connecting to a Wired Modem with WiFi
This common way of connecting WiFi devices to a wired modem requires that a wireless router be connected to the wired modem. This wireless router connects to the modem via ethernet cable. The Internet connection is then made available to nearby wireless devices through a signal transmitted by the wireless router. Enabling WiFi on a Pocket PC with WiFi capabilities will allow the device to detect the wireless Internet connection and connect to it.Wireless routers may be encrypted and require a user name and password to access the secure wireless connection. When WiFi is enabled on a Pocket PC or PDA device, the device will scan for nearby networks and display both secured and unsecured networks. If the user lacks access to a secure network, the device can connect to public or unsecured wireless networks if they are available
