HSDPA modems connect to advanced wireless 3G networks, allowing for higher transfer speeds and data capacities. They come in USB, router, and landline replacement forms, but rely entirely on cellular signal.
A High-Speed Downlink Packet Access (HSDPA) modem is a device used to connect to an advanced wireless 3G network. An HSDPA modem is part of the High-Speed Packet Access (HSPA) family which may also be referred to as 3.5G or 3G+. This is because it allows for higher transfer speeds and data capacities than traditional 3G data transfer systems.
An HSDPA modem allows users to connect to the cellular wireless network in areas that support HSPA. In areas that do not support HSPA, the HSDPA modem may not connect at all or may connect at slower speeds. It depends on the modem model.
Once the HSDPA modem is connected, users can enjoy speeds of up to 14.0 Megabits per second (Mbit/s). The speed of the connection depends on many variables. The main concern when trying to get the fastest connection is usually the signal level. In areas with stronger 3G signal, the connection speed will be faster.
There are many types of HSDPA modems available. HSDPA USB modems are often the most portable and convenient of the types available. This allows you to establish a high-speed connection with any computer with a USB port in areas with 3G coverage. This makes it popular for use with laptops to provide internet connection in many different places.
Another popular type of HSDPA modem comes in the form of an HSDPA router. These routers work like most wireless routers, creating a WiFi network. Instead of using DSL or cable internet, these routers use HSPA to connect to a wireless 3G network. This allows users to create a WiFi network anywhere that can receive a 3G cellular signal. This can allow computers without an HSDPA modem to share the wireless connection.
USB HSDPA modems and routers allow users a high degree of portability for their Internet connection. HSDPA landline replacements take a different approach. These devices work just like an HSDPA router, creating a WiFi network, as well as allowing you to connect via Ethernet lines. In addition to this, HSDPA landline replacements offer ports that allow users to connect their traditional landline phones to the router. This allows “landlines” to use the high-quality HSPA system that previously only mobile phones could use.
The benefits of using an HSDPA modem are obvious. The main disadvantage of these devices is that they rely entirely on the ability to get a cellular signal. This can be a particular burden when attempting to use these devices indoors.
