Gateway vs. Modem – Which reigns supreme

In your search for the right network set up, you might have to choose between a gateway and modem as they are both popular and well-rated in the market. Which one performs better between the two?

Beyond router systems and range extenders, two of the most sought-after networking devices are gateways and modems. They both offer unmatched benefits once you connect them to your network. A gateway for instance works as a buffer between connected users and the internet connection. It does this by analyzing the flow of traffic for any malicious content or non-compliance with policy guidelines. Modems on the other hand are translators and transmitters between internet-connected devices. Wireless modems transfer data signals from different channels.

While there are many commentaries and testimonials on this networking devices, this article is an in-depth analysis of both. It gives an overview of both gateways and modems to help you choose between the two. After all, they do have a lot going on for them but having both devices connected to your network could be quite the overkill.

What are the differences between a Gateway and a Modem?

Modem (Winner) 
Wide variety including bulky to compact sized
Depends on version i.e. cable, wireless, fiber optic
Variation of prices
Widely varies depending on model

Cable digital translator between devices


Gateway vs. Modem – A look at how they differ


Accurately known as a modulator-demodulator, modems basically do the translation of data signals between an internet service provider and connected computer. It does this such that data is more ‘computer friendly’ for an even enhanced performance. While modems usually come in small sizes, its performance as a digital translator is quite high-tech.

Gateways on the flipside offer a secure connection between connected devices. To add, gateways are often referred to as a modem and router combined given the performance they offer.


Gateways come in a wide range of designs. However, most security gateways come with common features cutting across. For example, the Ubiquiti Unifi Security comes in a fan-less design and is a good fit for environments like offices that require silence for proper working.

Modems on the flipside, also have widely varying designs. Digital modems for instance, come in small and modernized sizes making them easily blend with wherever you have them. You can also get rather bulky modems that are specifically designed for complex environments.


A gateway is a networking device that works just as its name suggests. When installed between two networks, it often acts as a “gate” between them. While there are dedicated gateways like Zyxel Unified Security Gateway and Ubiquiti Unifi Security Gateway, a gateway can also be a router, server or firewall. Simply put, a gateway can be right about any networking device that controls and manages the traffic flow between networks.

This article has given an overview of security gateways as they are well-reviewed and one of the most sought after devices in the networking industry. While gateways may be built-in with a network, they usually come as a separate node in itself like those mentioned in this guide. The Ubiquiti Unifi Security Gateway for example enables the traffic flowing in and out of the network. Gateways can also go ahead and translate data as received into a “computer-friendly” format that can be understood by the connected devices within the network.

  1. Can you use both networking devices in one system?

Yes. The gateway offers some kind of ‘gate’ while a modem works as a translator of Wi-Fi signals. Together they make the ideal network system.

  1. What is their band technology?

Depending on the manufacturer, gateways and modems can either be dual or tri-band.
