Modem Types

A modem is a device that allows a computer to access the internet. There are several types of modems available, each with its own advantages and disadvantages.

The most common types of modems are cable modems, dial-up modems, DSL modems, GSM modems, and CDMA modems. Check out the following explanation:

modem cable

Cable modems are the most popular type of modem and are up to 10 times faster than telephone modems. They're easy to set up with an app on your phone and work with most major internet providers. Such as IndiHome, First Media, MNC Play, and many more.

Dial-Up Modems

A dial-up modem is a device that allows a computer to connect to the internet using an existing telephone line. They convert data from analog to digital form, enabling computers to communicate with each other.

DSL modems are used to connect your computer, TV and other devices to the internet, while wireless modems provide access without physical cables.

GSM modem

A GSM (Global System for Mobiles) modem is a type of cellular network that uses a SIM card to store data and connect to the network. This is the most widely used type of cellular network, and is used by most cell phone providers.

GSM networks use radio frequency systems to transmit voice and data, and are typically used in areas with good coverage.

CDMA modems

CDMA stands for Code Division Multiple Access, and is a type of cellular network technology used for cellular communications. It is one of the two main types of mobile networks, besides GSM.

CDMA is a type of multiplexing technique that allows multiple users to access one radio frequency channel at the same time.
