Modem, a term derived form Modulator-Demodulator used to stand for a device that allowed a computer or terminal to transmit data over a standard dial-up telephone. This description of a modem is inadequate and was suitable only until the late 1990s. Since the advent of high-speed cable and DSL connections, modem now refers to devices that offer low-speed dial-up or high-speed broadband. Taking technology one step ahead, the wireless 3G modem provides global wireless access to the Internet and e-mail.
USB wireless 3G modem creates connection of computers and private networks with the Internet as the primary or back-up route. It is especially suitable for desktop users seeking permanent wireless Internet connection and users in rural areas where no other means of broadband Internet are available. It is also equally suitable for users on the move who want to take their connection with them all the time.
As mentioned above, the wireless 3G modem provides global wireless access to the Internet and e-mail on HSDPA (High Speed Downlink Packet Access) capable UMTS networks. With a speed of up to 1.8Mbps down and 384kbps up, it enables users to enjoy access to wireless connectivity similar to DSL or cable modems. In addition to supporting high-end HSDPA technology, the wireless 3G modem is also compatible with UMTS, EDGE and GPRS networks.
This capability of the wireless 3G modem makes it an ideal device for operators planning to upgrade their networks to HSDPA as it currently supports deployed wireless broadband technologies (WCDMA 2100MHz, EDGE Class 10 Quad band). By virtue of this technology, you can get access to the Internet using your 3G mobile phone as a modem by simply connecting your handset to your PC with a USB cable. What more, while you are browsing the net, you can still use your 3G mobile to make and receive phone calls or send and receive text messages.
