HSDPA USB modems provide fast mobile broadband, faster than 3G but not as fast as 4G. They act as an antenna to pick up signals and process data for computers. They can replace landline broadband but may be expensive with lower download limits. Dedicated devices are preferred for home broadband.
An HSDPA USB modem is a device used to access a particularly fast form of mobile broadband. It runs on the HSDPA system, which offers faster speeds than commonly used 3G systems, though not as fast as 4G systems such as WiMax. It is also possible to use a USB HSDPA modem with a home computer as a replacement for landline broadband.
HSDPA stands for High-Speed Downlink Packet Access. It is used to transmit data over the high-speed mobile phone network. HSDPA is faster than systems currently used for most mobile Internet services such as EDGE, commonly used for the iPhone. It is not as fast as the “next generation services” that fall under the 4G classification. For this reason, HSDPA is often referred to as 3G+ or even 3.5G.
In the case of a smartphone, high-speed Internet signals can be picked up by the phone’s antenna and then processed by the phone. With a portable computer such as a laptop or netbook, the computer usually won’t be able to pick up the signal itself; most computers are only equipped to receive mobile signals via Wi-Fi or possible Bluetooth®. The solution is a USB modem, which looks like a memory stick and plugs into a USB socket. The USB modem acts as an antenna to pick up the signal, then processes it into data that the computer can use.
As with any mobile broadband service, using an HSDPA USB modem can be expensive. Most service providers impose much lower monthly download limits than landline services. Many users will find that these limits cover their needs, but those who exceed them may face extremely large penalties or “excessive” charges.
In theory an HSDPA USB modem can be used to provide Internet connections to a home computer where there is a good HSDPA signal. This would eliminate the need for a landline connection. Whether this makes financial sense varies from case to case, although it can work well for people who have good HSDPA coverage but don’t have good quality landline broadband service in their area or where this service is expensive. Instead of using an HSDPA USB modem, however, most people using HSDPA to get home broadband will instead use a dedicated device that plugs into a wall outlet and also includes a jack for connecting a telephone. traditional.
