La velocidad de descarga es la rapidez con la que la información viaja desde Internet hasta tu dispositivo; la velocidad de carga es la rapidez con la que la información viaja desde tu dispositivo hacia el Internet. - La mayoría de las conexiones residenciales son asimétricas, lo que significa que la velocidad de descarga y la de carga no son iguales, aunque la diferencia entre ambas puede variar según el tipo de conexión que se tenga. - La velocidad no es el único factor que importa. Latency (often measured as "ping") and the number of devices sharing a network can also affect how a connection feels day to day, separate from raw upload or download numbers. ## Upload vs. download speed at a glance Here's a quick side-by-side look at how download and upload speed differ, including what each one typically affects and who tends to rely on it most. | | Velocidad de descarga | Velocidad de carga | |----------------------------|---------------------------------------------------------------------|------------------------------------------------------------------------------------------| | Qué mide | Datos que se transfieren del Internet a tu dispositivo | Datos que se transfieren desde tu dispositivo a Internet | | Casos de uso típicos | Streaming de video, navegación, descarga de archivos, recepción de videollamadas | Envío de archivos, videollamadas, streaming en vivo, gaming en línea, copias de seguridad en la nube | | ¿Quién suele darle prioridad? | Usuarios de servicios de streaming, usuarios de navegación general y hogares con múltiples dispositivos conectados | Trabajadores remotos, creadores de contenido, usuarios de videollamadas, jugadores competitivos | | Patrón de conexión común | Por lo general, más alta en la mayoría de las conexiones que no son de fibra óptica | Por lo general, es más baja en la mayoría de las conexiones que no son de fibra óptica, excepto cuando se ofrecen velocidades simétricas | ### When download speed matters more - Streaming movies, shows, or music - Navegación de sitios web y redes sociales - Descarga de archivos grandes, juegos o actualizaciones de sofware - Households with several devices streaming or browsing at once ### When upload speed matters more - Making video calls or hosting virtual meetings - Streaming en vivo de partidas o eventos - Carga archivos grandes, fotos o videos a la nube - Copias de seguridad de los dispositivos automáticamente - Online gaming, where your inputs need to reach the game server quickly ## What is download speed? La velocidad de descarga afecta la rapidez con la que la información viaja de Internet a tu dispositivo. De esta forma, la velocidad a la que recibimos mensajes de texto, videos, descargamos páginas web, vemos videollamadas y cualquier otra información que podamos necesitar de Internet se ve afectada por la velocidad de descarga. Las velocidades de descarga dependen de muchos factores, como el tipo de plan que tengas, los tipos de dispositivos que utilices y la cantidad de dispositivos que intenten acceder a la red al mismo tiempo. Slow download speeds can be one of the main culprits behind that annoying video game lag or interruptions in streaming movies and television. ## What is upload speed? Si bien se presta mucha atención a la velocidad de descarga, la velocidad de carga también es importante. La velocidad de carga se refiere a la rapidez con la que la información viaja desde un dispositivo a Internet. La velocidad de carga afecta la rapidez con la que los archivos pueden cargarse desde tu computadora a Internet, lo cual es especialmente importante si trabajas desde casa, por ejemplo. La velocidad de carga puede repercutir en cuestiones como las videollamadas, ya que tienes que enviar tu imagen de video a la persona o las personas con las que estás hablando. En el gaming, la velocidad de carga puede afectar la rapidez con la que la pantalla refleja tus entradas al juego a través del control. So even though upload speed is generally lower than download speed, it can still impact your overall online experience. ## What factors affect upload and download speeds? Existen muchos factores que pueden afectar a las velocidades de carga y descarga, desde el ancho de banda de tu plan hasta la ubicación del enrutador en tu hogar. Here are the most common ones to be aware of: ### 1. Latency Latency describes the delay in data transfer between your device and the server. [Latency](https://www.t-mobile.com/home-internet/the-signal/speed/what-is-latency) is usually measured in milliseconds, and even a few fractions of a second of latency can cause a noticeable delay, as anyone who has ever experienced latency in the middle of a video call or critical scene in a movie can attest. ### 2. Ping Ping is another term used for this slowdown, often heard in online gaming. El ping es una herramienta de medición utilizada para probar la latencia. A small packet of data (called a "ping") is sent to a server, and the time it takes for that data to make the round trip is measured to calculate latency. ### 3. Router or gateway location Another factor that can affect internet speed is the location of your router or gateway. If you're connecting to a [Wi-Fi](https://www.t-mobile.com/home-internet/the-signal/internet-devices/what-is-wifi) network, it's important to experiment with different locations to find an ideal spot, since upload and download speeds can be affected by things like distance, physical barriers and more. ### 4. Bandwidth [Bandwidth](https://www.t-mobile.com/home-internet/the-signal/internet-devices/what-is-bandwidth) describes how much information your network can receive in a second - and it's shared across every device connected to your network. Este efecto de ancho de banda compartido puede ser más perceptible en las conexiones por cable, donde influye el uso que hacen los vecinos, en comparación con los tipos de conexión que utilizan líneas exclusivas. So if you're streaming a movie in the living room, someone else is watching videos in the bedroom, and the kids are in the middle of an intense gaming session, that available bandwidth gets divided among all those devices, which can affect both upload and download speeds. ## Symmetrical vs. asymmetrical speeds Not all internet connections treat upload and download the same way. - Asymmetrical speeds mean download and upload speeds are different, with download typically higher. Las conexiones por cable y DSL son ejemplos comunes de esto. Este diseño refleja la forma en que la mayoría de los hogares utiliza Internet: por lo general, se recibe más información (streaming, navegación) de la que se envía. - Las velocidades simétricas significan que las velocidades de carga y descarga son iguales o muy similares entre sí. Las conexiones de fibra óptica suelen ofrecer velocidades simétricas, ya que la tecnología subyacente de la fibra óptica no favorece intrínsecamente una dirección sobre la otra, a diferencia de lo que ocurre con el cable y el DSL. If you regularly upload large files, livestream, or rely heavily on video calls, it's worth checking whether your connection type and plan offer closer-to-symmetrical speeds. ## 7 Steps to check and improve your speeds If you want a clearer picture of your connection's performance, a few steps can help: 1. Realiza una prueba de velocidad utilizando una herramienta en línea confiable para medir tu velocidad de descarga, velocidad de carga y ping. 2. Test over a wired (Ethernet) connection when possible, since Wi-Fi can introduce additional variables like interference or distance from the router. 3. Run tests at different times of day to see whether performance changes during peak usage hours. 4. Compare your results to your plan to understand whether your connection is performing as expected. 5. Move your router or gateway to a more central, open location if Wi-Fi speeds seem inconsistent. 6. Reduce interference from other electronics, thick walls, or overlapping Wi-Fi networks where possible. 7. Check the number of connected devices, since more devices sharing a network can affect both upload and download performance. ## What are "good" download and upload speeds? La respuesta será diferente para cada persona, ya que depende del estilo de vida. If you live alone and only use the internet for occasionally checking email and browsing the web, you probably don't need the same bandwidth as a family of five with multiple gaming consoles, laptops, mobile phones, streaming televisions, and smart appliances. ## FAQs about download vs upload speed __Why are download speeds usually faster than upload speeds?__ Many home internet technologies are built asymmetrically because typical household usage pulls more data than it sends - think streaming and browsing versus uploading files. Cable, DSL, and most wireless connections tend to prioritize download speed, while fiber more commonly offers symmetrical speeds. __What is jitter, and how is it different from latency?__ Jitter refers to variation in latency over time - rather than a delay staying steady, it fluctuates. High jitter can cause choppy video calls or inconsistent gaming performance, even if average latency and speed look fine on paper. __Can I have fast download speed but slow upload speed at the same time?__ Yes. Because most connections are asymmetrical by design, it's common to have noticeably higher download speed than upload speed on the same connection. __Does the number of connected devices affect upload speed as much as download speed?__ Both upload and download speeds can be affected when multiple devices share the same network, since bandwidth is a shared resource. Activities that rely more heavily on upload, like video calls or livestreaming, may become more noticeable if several devices are active at once. __Does using Wi-Fi affect upload and download speeds differently than a wired connection?__ Wi-Fi can introduce variables like interference, distance from the router, and signal obstructions that don't apply to a wired Ethernet connection. This can affect both upload and download performance, though the impact can vary based on your home's layout and router placement. __What internet types are likely to offer closer-to-symmetrical upload speeds?__ Fiber-optic connections are the connection type most commonly associated with symmetrical or near-symmetrical upload and download speeds, though availability depends on your provider and location. ## Comparing upload and download speeds Upload and download speed each play a distinct role in your everyday internet experience. Comprender en qué se diferencian, junto con factores como la latencia, el ancho de banda y el tipo de conexión, puede ayudarte a solucionar problemas de manera más eficaz y a tomar decisiones mejor fundamentadas sobre la configuración de tu Internet residencial. If you're evaluating a new plan or connection type, it's worth looking into both the download and upload speeds offered, along with how your household actually uses the internet day to day. __You might also be interested in:__ - [Explore T-Mobile Travel Benefits](https://www.t-mobile.com/benefits/travel) - [In-Flight Wi-Fi: Unlimited Internet, Streaming & Texting](https://www.t-mobile.com/benefits/travel/in-flight-wifi) - [5G Network](https://www.t-mobile.com/support/coverage/t-mobile-network) - [5G Coverage Map](https://www.t-mobile.com/coverage/coverage-map) - [Affordable hotspot data plans](https://www.t-mobile.com/cell-phone-plans/affordable-data-plans/hotspots) - [Best mobile hotspot devices](https://www.t-mobile.com/dialed-in/devices/best-hotspot-devices) - [What is a hotspot?](https://www.t-mobile.com/iot-devices/hotspots) Tags - [Compare](https://www.t-mobile.com/home-internet/the-signal/archive/compare) - [Latency](https://www.t-mobile.com/home-internet/the-signal/archive/latency) - [Router](https://www.t-mobile.com/home-internet/the-signal/archive/router) - [Wi-Fi](https://www.t-mobile.com/home-internet/the-signal/archive/wi-fi) ## Related Articles [Read More](https://www.t-mobile.com/home-internet/the-signal/speed/why-your-wi-fi-is-slow-and-how-to-fix-it) [](https://www.t-mobile.com/home-internet/the-signal/speed/why-your-wi-fi-is-slow-and-how-to-fix-it) [Speed](https://www.t-mobile.com/home-internet/the-signal/category/speed) ## [Why is My Internet Slow?
