What is a 3G modem?

and 3G modem is a device that allows the computer to connect to the Internet via a high -speed mobile connection. This means that the internet signal is transmitted on wave waves rather than being sent and received via a cable or telephone line. This technology is largely the same that is used to supply Internet content to modern mobile phones. The most common standards in the United States are UMTS and CDMA. Since different standards are not always compatible with each other, users must carefully check that a 3G modem is compatible with a network of mobile phones from which they intend to get a 3G service. This is usually connected to a USB slot on a computer and is very similar to a portable memory unit. The device is located that the Antennas THAT receives a signal, a SIM card that verifies users to communicate in the network, and the modem itself that converts wireless information to data to which the computer can understand.

Some forms of 3G modem also function as a router, which means that the signal can share with multiple devices. Some such routers are relatively large devices and include Ethernet slots for cable connection to computer. Others are smaller and communicate with computers via Wi-Fi. It can be a useful solution for portable devices that have Wi-Fi connection but do not have a USB socket,

3G modem will often have to be much more cautious about using the Internet than someone of landlines or cable services. This is because there are usually much lower monthly data limits that can be downloaded. They can be up to 250 MB and rarely exceed 5 GB per month. A user who sells this limit can be interrupted for the rest of the month, but could also be allowed to continue using the service and charge extremely high penalty fees for additional data use.

There are also several 3G technologies thatThey are designed to work primarily for desktops. One example is Wimax, which some homeowners can use as their primary Internet connection. This is really practical only in areas that have strong Wimax coverage, but where fixed lines or cable services are not available or disproportionately expensive.
