Not all plans are available in all areas. Provider plan, availability, and speed tier data provided by BroadbandNow.com. Speedtest real-world data is only present where sample size has reached significance within a region. Additionally, averages may include aggregated tests across multiple Internet Types (Fiber, DSL, Cable, etc.).

At Speedtest, we take pride in offering accurate and reliable data, serving as the foundation for our ISP recommendations. Our data is gleaned from worldwide Speedtest results by millions of users, affording us a trustworthy and up-to-date view on ISP performance. This enables us to present an unbiased perspective on the capabilities of ISPs.

Three key metrics to consider when evaluating an ISP include download speed, upload speed, and latency. Download speed is vital for streaming and downloading, affecting how quickly data reaches your device. Upload speed is crucial for sending data from your device to the internet, impacting online interactions. Latency, or ping, is significant in video conferencing and online gaming, affecting the responsiveness of your online experience. Armed with this comprehensive understanding, you can make an educated decision aligning with your specific internet needs.

The technology behind your ISP significantly influences your internet experience. Fiber optics, for instance, typically provides the fastest speeds, ideal for demanding online activities. Cable internet offers commendable download speeds but might have slower upload speeds. DSL provides adequate speeds for basic internet use, whereas satellite internet, often the sole option in remote areas, usually exhibits higher latency and reduced speeds.

How Much Speed Do I Need?

Download speeds of at least 100 Mbps and upload speeds of at least 10 Mbps are widely considered fast enough to handle nearly any online activity. A quick guide to what speeds you need for different online activities is below, and you can read our full guide to internet speeds and performance for more information. Keep in mind that the numbers below are the bare minimum for one device at a time. If you’re trying to use multiple devices on a network at the same time, you’ll want higher speeds.

Home Internet in San Jose

This variety is essential in a city known for its technological advancements and high internet demand.

Providers like XFINITY and AT&T Fiber, which offer the most extensive city coverage when excluding satellite and fixed wireless from the data set, lead in service availability. XFINITY, primarily a cable internet provider, covers 98.39% of the city, while AT&T Fiber, which offers fiber internet among its other services, has a significant presence covering 91.47% of San Jose. Between these two carriers and the other city options, San Jose residents are ensured comprehensive service to a large portion of the population.
