This is especially convenient for allowing laptops and mobile devices onto to the Wi-Fi network for internet access or giving accessibility to a printer with Wi-Fi capabilities that anyone logged into the network may utilize. The router will allow PCs and other connected devices to access the internet and other networks.Ī wireless router can also transmit a Wi-Fi signal that wireless devices may connect to. The majority of routers have a single LAN port and single WAN port, while a switch will have multiple ports for different devices to communicate within the LAN such as PCs and printers. In simpler terms, the Ethernet switch creates networks and the router allows for connections between networks. Hopefully, this brief article will enable you to distinguish the difference between different types of devices and understand what is meant by a saying: every Router is a Gateway and every Gateway is a Modem but not the other way around.While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. A very good example of this is Teltonika TRB series devices. Thus, it can be said that Routers are meant to connect multiple devices to internet and Gateways are meant to connect only one device. While Routers are designed to manage multiple interfaces, Gateways usually are designed to have only one interface. So how are they different? The principal difference between Routers and Gateways is number of interfaces it can support. ![]() Both Routers and Gateways work autonomously both are usually equipped with extensive security functionality such as firewall and data tunneling capabilities. When you look at the functionality of majority of Gateways and Routers you will find many similarities. Term Gateway gets often mixed up with term Router and there is an excellent reason why. Gateway is a term widely used and quite often misused while talking about networks. Teltonika RUT series devices are a great example of Routers. All in all, Routers are best defined as Networking devices that do provide a secure internet connection to multiple devices simultaneously. These features provide extensive data security and lower risk of cyberattacks. Routers are usually equipped with advanced data security services such as firewalls and multiple data tunneling services. Another massive difference between Modems and Routers is software functionality. This capability of handling multiple interfaces and various devices connected to it makes Routers very versatile and adaptable to a use case scenario. They possess data routing capabilities allowing to provide internet access to multiple devices simultaneously. Moreover, Routers can provide internet connection to multiple devices through multiple interfaces. Routers can and do provide internet connection autonomously. When router is used, there is no additional need to use another device to control it. It can be said that every Router has a Modem built-in. Routers, similarly as Modems are used to provide and manage internet connection. ![]() RoutersĪs we established, that Modems are one of the simplest networking devices let’s move on to Routers that are the most advanced devices in networking. ![]() ![]() A good example of this type of device is Teltonika TRM Modems. Similarly, to a key, majority of Modems cannot make a connection without the help of software running on the device it is connected to. Moreover, Modem works like a key, a key to the internet. Historically, Modems are considered primitive devices that are not programmable thus data security services and traffic routing capabilities are not present in such devices. A modem is a piece of hardware built solely to do one task and one task only – send traffic from point “A” to point “B” without doing anything with data. A modem is one of the oldest terms used when talking about Networks. So, is it just a fancy way of naming different products or do these terms actually help to distinguish different devices? This article aims to discuss the functionality and recognize the key differences between Routers, Gateways and Modems. At the end of 2018, we also released a series of IoT Gateways called “TRB” and most recently - “TRM” Modem series. For example, Teltonika Networks are most famous for their Routers. It gets even more confusing when these terms are used in very similar topics. When talking about networks you can hear loads of different terms: Routers, Gateways, Modems.
