What about Wi-Fi 7? How do these newer generations 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 and Wi-Fi 7 - so you can find the best fit for your [home internet](https://www.t-mobile.com/home-internet) needs. ## 3 Key takeaways about dual-band routers - Dual-band routers broadcast two signals at once. La banda de 2.4 GHz está diseñada para alcanzar mayores distancias y atravesar paredes y suelos, mientras que la banda de 5 GHz opera en un conjunto de canales más amplio, lo que puede ayudar a reducir la congestión en zonas con muchas redes cercanas. - La mayoría de los enrutadores modernos admiten ambas bandas automáticamente. Muchos enrutadores incluyen una función llamada direccionamiento de banda, que dirige el dispositivo que se conecta a la banda que el enrutador determina que está disponible, sin necesidad de que elijas manualmente. - No todos los dispositivos admiten 5 GHz. Some smart home devices, like garage door openers, baby monitors, and older smart appliances, only connect to 2.4 GHz, which is one reason dual-band support matters even for simple setups. ## Single-band vs. dual-band vs. tri-band: Which fits your situation? Hoy en día, los enrutadores se venden generalmente como de una sola banda, doble banda o triple banda. La siguiente tabla resume la diferencia básica entre cada tipo, para que puedas ver dónde encaja la tecnología de doble banda antes de decidir qué necesita tu hogar. | Tipo de enrutador | Bandas que transmite | Uso recomendado | |---------------------------------|-----------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------| | Una sola banda | Solo 2.4 GHz | Espacios muy reducidos o un número reducido de dispositivos básicos conectados | | Doble banda | 2.4 GHz + 5 GHz | La mayoría de los hogares, con una combinación de dispositivos para el hogar inteligente, laptops, teléfonos y dispositivos de streaming | | Tribanda | 2.4 GHz + dos señales independientes de 5 GHz | Hogares con muchos dispositivos conectándose simultáneamente a la banda de 5 GHz, donde una señal adicional de 5 GHz puede ayudar a distribuir dicho tráfico | | Wifi 7 (triple o cuádruple banda) | 2.4 GHz + 5 GHz + 6 GHz (algunos modelos añaden una segunda señal de 5 GHz) | Hogares con dispositivos más recientes compatibles con wifi que pueden aprovechar la banda adicional de 6 GHz | Para la mayoría de los hogares, un enrutador de doble banda cubre las necesidades de una combinación típica de dispositivos. Tri-band routers add a second 5 GHz signal, which can be useful in homes where many devices - such as several streaming devices, gaming consoles, and laptops - are all trying to use 5 GHz at the same time. ## How dual-band Wi-Fi works 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 This was designed to travel farther at lower speeds. 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. Sin embargo, a medida que el wifi se popularizó y más hogares adoptaron Internet de alta velocidad, la banda de 2.4 GHz se saturó cada vez más, sobre todo en lugares como edificios de apartamentos donde, a pesar de que cada apartamento tiene su propio servicio de wifi, todos los dispositivos utilizan básicamente las mismas señales, y esto hace que la velocidad de Internet de todos disminuya. La banda de 2.4 GHz también puede verse afectada por otros dispositivos electrónicos del hogar que operan en la misma frecuencia o en una cercana. Common sources of interference include microwave ovens, cordless phones, Bluetooth devices, and baby monitors that operate on 2.4 GHz. ### 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? Si alguna vez miraste las opciones de banda que aparecen en la pantalla de tu laptop o teléfono móvil y te preguntaste cuál elegir, no eres el único. 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. ### What about Wi-Fi 7? Wifi 7 es la generación más reciente de tecnología inalámbrica; se basa en wifi 6 y ofrece compatibilidad con una gama más amplia de canales, así como la capacidad de utilizar varias bandas simultáneamente para una misma conexión. Se diseñó para reducir aún más la latencia y gestionar una mayor cantidad de dispositivos conectados simultáneamente, lo que resulta útil en hogares con un número creciente de dispositivos inteligentes, reproductores de streaming y consolas de gaming. Not all devices support Wi-Fi 7 yet, so the benefit depends on having compatible hardware on both ends of the connection. ## Where tri-band and mesh systems come in In homes with a large number of connected devices, or homes spread across multiple floors, a single dual-band router may not comfortably cover every room or every device. Los enrutadores tribanda, que añaden una segunda señal de 5 GHz, son una opción para los hogares donde muchos dispositivos utilizan la banda de 5 GHz simultáneamente. Algunos enrutadores más recientes, incluidos ciertos modelos wifi, llevan esto un paso más allá con configuraciones de tres o cuatro bandas diseñadas para gestionar una mayor carga de dispositivos. Los sistemas wifi mesh, que utilizan múltiples puntos de acceso distribuidos por toda la vivienda, son otra opción para mejorar la cobertura en distribuciones amplias o de varias plantas. If you're outfitting a larger home, it may be worth researching mesh systems as a complement to, or replacement for, a single dual-band router. ## FAQs about dual band Wi-Fi routers __What does a dual-band router actually do?__ A dual-band router broadcasts Wi-Fi on two separate frequencies - 2.4 GHz and 5 GHz - at the same time, so devices in your home can connect to whichever band suits them. This helps spread devices across two signals rather than everything competing for one. __Should I enable both 2.4 GHz and 5 GHz on my router?__ In most cases, yes. Keeping both bands enabled allows devices that only support 2.4 GHz to connect, while other devices can use 5 GHz. Many routers also offer Band Steering or separate network names for each band if you want more control. __How can I tell which band my device is connected to?__ You can typically check this in your device's Wi-Fi settings, in your router's admin page, or through your router or gateway's companion app, if it has one. Some routers broadcast separate network names for each band, which makes it easier to see which one a device selected. __Is a dual-band router different from a tri-band router?__ Yes. A dual-band router broadcasts one 2.4 GHz signal and one 5 GHz signal, while a tri-band router adds a second, separate 5 GHz signal. The extra 5 GHz signal on a tri-band router is intended to give homes with many 5 GHz devices more room to distribute that traffic. __Does using a dual-band router change my internet plan's speed?__ No. A router's band configuration doesn't change your internet plan itself. Dual-band gives your devices two wireless signals to connect to; actual performance still depends on your internet service and home conditions. __Can I give the 2.4 GHz and 5 GHz networks different names?__ Yes, most routers allow separate network names (SSIDs) for each band. Some households do this to manually choose which band a device connects to, rather than relying on automatic Band Steering. __Do all of my devices support 5 GHz?__ Not necessarily. Many smart home devices, including some garage door openers, baby monitors, and older smart plugs, are built to only connect to 2.4 GHz. This is one of the main reasons dual-band routers remain useful even in homes with newer devices. __What is Band Steering?__ Band Steering is a router feature that automatically connects a device to whichever band the router determines fits best at that moment, based on signal conditions. It's designed to reduce the need for people to manually choose a band for each device. __Is one band more secure than the other?__ Security on a Wi-Fi network is generally determined by the encryption and password settings you configure, such as WPA2 or WPA3, rather than by the band itself. Both 2.4 GHz and 5 GHz can be configured with the same security settings on most routers. __How many devices can a dual-band router support?__ This varies by router model. Because a dual-band router splits devices across two bands, it can generally accommodate more simultaneously connected devices than a single-band router, though actual performance also depends on your internet service and how many devices are active at once. __Do I need a Wi-Fi 7 router?__ Not necessarily. Wi-Fi 7 can offer benefits like lower latency and more available bandwidth, but you'll only see those benefits if your devices also support Wi-Fi 7. For most households, a Wi-Fi 6 or dual-band router still covers everyday needs well. ## Where to begin Dual-band Wi-Fi gives your home's devices options: a 2.4 GHz band built for reach and compatibility with older or simpler devices, and a 5 GHz band offering more available channels for devices closer to the router. T-Mobile, el proveedor de Internet residencial de más rápido crecimiento del país, ofrece equipos de conexión que funcionan tanto con wifi 6 como con wifi 7, según su configuración, y son compatibles con las redes nacionales 4G LTE y 5G de T-Mobile.
