![]() ![]() Cable modems connect a customer's LAN to the coax network by bridging the Ethernet packets. Cable modems are generally used to offer cable Internet access, which uses the high bandwidth of an HFC and RFoG network.Ĭable modems comply with IEEE 802.1D for Ethernet networking in network topology (with some modifications). What is a Cable Modem?Ī cable modem is a type of network bridge that uses radio frequency channels to allow bi-directional data communication across a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG), or coaxial cable infrastructure. A typical modem converts a computer's digital data into a modulated electrical signal for transmission over telephone lines, which is then demodulated by another modem at the receiver side to retrieve the digital data. ![]() Modems may be used with nearly any analogue signal transmission method, including light-emitting diodes and radio. The objective is to create a signal that can be readily transferred and consistently decoded to recreate the original digital data. What is a Modem?Ī modulator-demodulator, or a modem, is a piece of hardware that transforms data from a digital format designed for direct communication between devices using specific cabling into a format suitable for transmission via telephone lines or radio.Ī modem encodes digital information for transmission by modulating one or more carrier wave signals, then demodulates signals to decode the delivered data. Read through this article to find out more about Routers and Modems and how they are different from each other. Routers connect devices across multiple networks. ![]() Routers work at the network layer and are responsible to find the shortest path for a packet, whereas Modems connect a device like desktop, laptop to the Internet. That said, the more devices you add, the trickier troubleshooting becomes, as each device can form a critical part of the home network connectivity chain: one weak link can result in no internet connection.Both Routers and Modems are network connecting devices. ![]() Mesh WiFi systems let you effectively add additional compatible WiFi satellites that act as routers, which means better and more consistent signal strength, all on which is treated as a single local network. In many respects, WiFi extenders are old tech when stacked next to their successor: the mesh WiFi system. These networking devices are designed to mirror and extend an existing WiFi network. If your internet is slow, you can always make use of a WiFi extender, booster or alternatives. WiFi extenders are handy for larger homes that want to expand the signal of a WiFi router to far-reaching parts of the home or outside. Technically, a modem can connect directly to a networking switch, but this would eliminate wireless connectivity in the home. For homes that want as many Ethernet connections as possible, a networking switch can connect to a router to further delineate local network traffic, whereby the router can mainly tackle wireless connections, and the switch takes care of wired connections. There are a couple of other networking gadgets in the home that are designed to liaise with a modem, a router, or a modem-router. ![]()
