How can I choose the best modem?

You want to choose the best modem, the first step is to identify your needs. Are you setting up a home network to share an Internet account between desktop and laptops? Maybe you're looking for a cellular broadband connection for your mobile phone, or may you like to upgrade the wireless network from 802.11g to 802.11n?

Today there are several types of modems for a variety of network needs on the market. Modems can first be categorized according to the type of service they support, followed by further considerations, such as whether the modem is internal or external and what functions it supports. Despite the diversity of available modems, the narrowing of possibilities is not so difficult.

External modems for setting up home or office networks: Modems are manufactured to adhere to the standard protocols that control the type of network services that support the device. Simply put, if you have Digital Subscriber Line (DSL), you will need a modem of DSL. ERNET Intod Cable Cable requires cable modem andOptical fiber subscribers, optical optical modem. In some cases, a modem will be produced to support more than one type of access such as DSL and cable.

If you want to share an Internet connection between several computers, a network hub is required together with the router. The HUB allows the modem to access multiple computers and the router processes the local network. Buying a modem with a built -in hub and router simplifies network networks. The modem can be connected or wireless, although even a wireless modem will have at least one Ethernet port and usually four.

If you buy a wireless modem, each computer connected to the device must install a wireless network card that supports a conventional wireless protocol such as 802.11n or older 802.11g. Getting a modem that supports all currently used protocols will save you from upgraded the older network cards.

Cellular Broadband Services: If you are interested in mobile cell internet, the first task of deciding on the carrier. Cell modems are marked for each carrier and cannot be used interchangeably. As a result, buying a cellular modem is relatively easy, as the carrier supplies the selection of compatible devices. Mobile mobile modems can be internal, but are commonly manufactured as USB dongles or fit into the ExpressCard ™ slot.

Technology

Cellular Broadband is developing and improving and creating new standards and protocols to compete for a large mobile communication market. Cell modems that support the technology of "yesterday" will be cheaper than those that support the standards "tomorrow". Since newer technologies generally achieve faster speeds with less energy consumption, it is usually worth investing in a model that supports standards violations. This means reading consumer reviews before buying a good idea because of mistakes moou be a factor in breaking hardware devices.

When buying any modem type, be sure to read systems requirements, as some models can only support specific operating systems. For mobile users, the ExpressCard slot has undergone many iterations, so make sure that the specified modem specification corresponds to your mobile phone specification.
