Is 600Mbps Internet fast or slow? In Spain’s current Internet market, 600Mbps fibre is considered a fast connection and is more than sufficient for the vast majority of households and users.

A 600Mbps fibre connection is enough for standard household use, including browsing the Internet, using social media and watching videos in 4K. However, whether it is the right speed for you will depend on your particular circumstances.

Please note: it is not right for every situation

The Internet speed you choose should reflect how many people and devices connect in your home and what they use the connection for. Depending on your usage, 600Mbps may be more than enough or may fall short.

And if you think this fibre speed must be expensive, think again! Lowi offers highly competitive 600Mbps Internet deals.

What can you do with 600Mbps fibre?

A 600Mbps fibre connection allows you to perform virtually any online activity smoothly. You can browse from more than five different locations around your home while maintaining a consistent connection.

600Mbps fibre is ideal for remote working, making video calls, playing online games, streaming or downloading films and, best of all, doing all these things simultaneously.

However, as mentioned above, performance will depend on how many people share the connection and use it at the same time. For example, imagine four people in your household are simultaneously:

  • Streaming 4K content.
  • Playing online games.
  • Making high-resolution video calls.
  • Downloading large files.

If this also happens during peak hours, you may notice a reduction in speed and the connection may not perform as smoothly as expected.

Is 600Mbps fibre enough? In most cases, yes. However, if you are a particularly heavy Internet user, you may want to consider 1Gbps fibre.

600Mbps fibre vs 1Gbps fibre

The main difference between 600Mbps fibre and 1Gbps, or 1,000Mbps, is the maximum data transfer speed. A 1Gbps connection provides approximately 66% more bandwidth than 600Mbps, equivalent to an additional 400Mbps:

  • With 1Gbps fibre, you will have one gigabit per second, equivalent to 1,000Mbps when connected directly through an Ethernet cable.
  • With 600Mbps fibre, you will receive download speeds of up to 600 megabits per second, which is 40% less than the previous option.

In addition, 1Gbps fibre allows you to use many devices simultaneously. Regardless of the time of day, you will always have plenty of connection capacity.

From a technical perspective, both connections use the same FTTH technology, meaning fibre to the home. There is no fundamental technological difference beyond the network configuration: the provider simply assigns a higher-capacity profile to the 1Gbps connection.

Do you need 1Gbps? Choose this option if:

  • You always want the maximum possible speed.
  • You play online games, watch 4K content, make video calls and download large files.
  • You do all these things simultaneously, including during peak hours.

If these factors are less important to you, 600Mbps fibre will be sufficient in most cases.

It is also important to note that making full use of a 1Gbps connection requires suitable equipment. For example, to achieve real-world speeds close to 1,000Mbps, you will need to connect directly to the router using a Gigabit Ethernet cable.

If high-speed Internet sounds appealing, remember that you first need to check whether it is available in your area.

To check, select the 600Mbps fibre plan and click “Lo quiero” (“I want it”). Check your fibre coverage and you’re all set!

Is 600Mbps fibre enough?

Although it is difficult to predict the future of communications, the answer is yes: 600Mbps fibre is currently more than sufficient for most households. If you are also weighing up a lower speed, find out whether 300Mbps fibre is enough, or work out how many Mbps you need at home.

Choose the 600Mbps fibre plan and remember that, if you later decide you do not need as much speed—or that you need more—you can switch to another of our home Internet plans.

Why choose 600Mbps fibre?

If you are still unsure and think 600Mbps fibre might be too much for you, there are many reasons to choose this speed:

  • Attractive price: Lowi’s 600Mbps fibre costs less than €30 a month, final price with VAT included.
  • Future-ready: if your needs change over the coming months, you will have enough speed for virtually any online activity.
  • Versatility: it allows you to perform any activity that requires Internet access.
  • Ideal for connected homes: households are using an increasing number of smart and IoT devices, and a 600Mbps fibre connection can keep them all connected.
  • Significant improvement: if you currently have a slower connection, upgrading will deliver a major increase in performance.
  • Better than other technologies: compared with non-FTTH options, choosing 600Mbps fibre instead of ADSL or mobile Internet is almost essential if you want maximum speed and stability.

At Lowi, we believe our 600Mbps Internet offers the best balance between performance and price.

What does 600Mbps fibre mean?

Here is a simple explanation of what a 600Mbps fibre Internet speed means:

  • Mbps or Mb/s means megabits per second, the unit used to measure Internet speed.
  • 600Mbps means that the connection can transfer data at a speed of 600 megabits per second.
  • Fibre-optic Internet is a high-speed technology that uses glass or plastic cables to transmit data through pulses of light. It provides faster and more stable speeds than traditional copper cabling.

Therefore, 600Mbps fibre refers to a fibre-optic Internet connection with a download speed of 600 megabits per second. It is a fast, stable connection with enough capacity to connect up to five devices simultaneously.
