If so, why does your [router](https://www.t-mobile.com/home-internet/the-signal/internet-help/difference-between-modem-router) offer both? The answer is that both bands can come in handy for different uses, depending on the size of your home and the type of device you're connecting to Wi-Fi.  #### Jump to a Section 1.

How does this new generation of wireless technology play into dual band, home internet, and the whole shebang? ¡No te pierdas con los números! We'll break down everything you need to know about Wi-Fi 2.4 GHz vs. 5 GHz-and Wi-Fi 6-so you can find the best fit for your [home internet](https://www.t-mobile.com/home-internet) needs. ## __What is dual band Wi-Fi?__ Wi-Fi works by using radio frequencies to transmit data through the air from your router to your connected devices. La frecuencia de transmisión inalámbrica por la que viajan estas señales se denomina banda. Cuando busques tu red wifi en un dispositivo, es posible que veas dos opciones para conectarte a tu red wifi doméstica: 2.4 GHz y 5 GHz. These two bands actually serve two different purposes: - __The 2.4 gigahertz (GHz) band__. Se diseñó para viajar más lejos a velocidades más bajas. Es la banda más común debido a su largo alcance y al hecho de que puede atravesar objetos como paredes para hacer llegar la señal wifi tradicional a todas las partes de una casa, apartamento u oficina. However, as Wi-Fi became popular and more homes adopted high speed internet, the 2.4 GHz band became increasingly crowded, especially in places like apartment buildings where, despite each apartment having its own Wi-Fi service, all devices are essentially using the same signals, causing everyone's internet speeds to slow down. - __The 5 GHz band__. While many confuse the 5 GHz Wi-Fi band option with [5G internet](https://www.t-mobile.com/home-internet/the-signal/speed/is-5g-home-internet-faster-than-regular-wi-fi), they're two different things. 5G internet is a cellular technology that provides connectivity to cellphones and homes. 5 GHz is a radio frequency on which Wi-Fi travels. Como alternativa a 2.4 GHz, la banda de 5 GHz transmite datos más rápido y suele haber menos dispositivos conectados a esta frecuencia, pero no transmite tan bien a través de paredes u otros obstáculos. If you're using cable, fiber, or DSL internet, you don't get a lot of choice in where you place your router due to the positioning of the receiver in the walls of our homes-so 5 GHz Wi-Fi bands, though faster, are sometimes not the best option. ## __Wi-Fi 2.4 GHz vs. 5 GHz: Which should you choose?__ If you've ever stared at the band options on your laptop or mobile screen wondering which one to choose, you're not alone. Hay un par de casos de uso diferentes para cada una. Algunos dispositivos, que incluyen electrodomésticos inteligentes, como los microondas, los monitores de bebés, los sistemas de seguridad y los abrepuertas de garaje, se conectan automáticamente a la banda de 2.4 GHz. Esto se debe a que la señal viaja más fácilmente a través de puertas y paredes, por no mencionar el hecho de que las velocidades de carga y descarga no son un factor tan importante para los electrodomésticos inteligentes como lo son para la transmisión de video o los juegos. Aunque seguramente alguna vez te haya molestado el buffering mientras hacías streaming de una película, es probable que nunca te haya enfurecido el retraso de la puerta del garaje. Algunos dispositivos no tienen capacidad para 5 GHz en absoluto, por lo que es importante contar con un enrutador de doble banda. Para otros dispositivos, tienes opciones. Si te conectas a una videoconferencia en una laptop, por ejemplo, o juegas a un juego de alta intensidad y múltiples jugadores en una consola, necesitas una conexión más fluida. Allí es donde la banda de 5 GHz puede ser una opción adecuada. Es por estos motivos que la mayoría de los enrutadores de la actualidad son de doble banda, lo cual significa que tienen capacidad para bandas de 2.4 GHz o 5 GHz. La mayoría de los enrutadores de doble banda ofrecen una función llamada "direccionamiento de banda", que conecta automáticamente el dispositivo a la red más potente disponible. Es una función útil cuando no estás seguro de cuál elegir. So, now that you have an understanding of what the different bands do, where does Wi-Fi 6 come into play? ## __How Wi-Fi 6 plays a role__ Wi-Fi 6, the latest generation of wireless technology, has the ability deliver up to 4X higher capacity-and up to 75 percent lower latency than its predecessor (Wi-Fi 5)1-which could translate to nearly triple the speed. ¿Qué importancia tiene eso? En los primeros tiempos del wifi, los hogares del país solo tenían uno o dos dispositivos conectados. Today, we have an average of 22 smart devices at home2. This could cause [problems with speed](https://www.t-mobile.com/home-internet/the-signal/speed/got-need-for-faster-internet-speed), since every device connected to Wi-Fi takes up bandwidth. Wi-Fi 6 is designed to handle higher volumes of traffic3. En términos de bandas, wifi 6 aumenta el número de flujos hasta un nuevo máximo de 12 en las bandas de 2.4 y 5 GHz. Wi-Fi 5 had a limit of 8 in a dual band configuration4. So, if you have a wireless router or a [gateway](https://www.t-mobile.com/home-internet/the-signal/internet-devices/what-is-5g-gateway) (e.g., modem/router combo) that supports this new Wi-Fi 6 technology, it can help maximize your devices' connection speed to the internet. ## __Where to begin__ T-Mobile, America's fastest growing [Home Internet](https://www.t-mobile.com/home-internet) provider, utilizes a wireless [5G Gateway](https://www.t-mobile.com/home-internet/gateway) that works in tandem with Wi-Fi 6 and is compatible with T-Mobile's nationwide 4G LTE and 5G networks. You can check to see if it's available in your area [here](https://www.t-mobile.com/home-internet/eligibility) and take a [test drive](https://www.t-mobile.com/home-internet/get-started) for 15 days to see if it's a good fit. Con el servicio de Internet 5G residencial de T-Mobile, no se necesitan instalaciones complicadas, cables coaxiales ni técnicos de cable. Se opera a través de una app que puedes bajar en tu teléfono o computadora. Once you [download the app](https://www.t-mobile.com/home-internet/app), you simply scan a barcode on your 5G Gateway, [find a good spot](https://youtu.be/QsTxXOc6i18) in the room, and [get connected](https://youtu.be/5jEjs8N7380) in less than 15 minutes. Once you're up and running, you can use that same app to [access your Gateway's info](https://www.t-mobile.com/support/tutorials/device/app/android/topic/t-mobile-internet-app/how-to-view-tower-connection-metrics/6), including which band you're currently connected to. Desde allí puedes actualizar según sea necesario. It's that easy! Want to simplify your world even more, while saving on Home Internet? Consider [bundling it with a phone plan](https://www.t-mobile.com/cell-phone-plans/phone-home-internet-bundle) from T-Mobile to get the best deal. ##### Explore Internet Equipment - [What is a Wireless Internet Service Provider (WISP)?](https://www.t-mobile.com/home-internet/the-signal/isp/what-is-a-wireless-internet-service-provider-wisp) - [What is Mesh Wi-Fi?
