WiFi

Radio bands mostly refer to 2.4 and 5GHz, and some of the latest routers can even use up to 60GHz. The most widely used is the 2.4GHz band, which is cheaper, but it also interferes with Bluetooth and other signals that use this band. This lower band is used quite often, so speed and stability vary greatly. The router at your home is most likely using this frequency.

However, if you run a business, stream a lot or simply need high-quality, fast Internet, the 5GHz band is much more suitable. This connection is more expensive, but it's much less overwhelmed and offers almost four times as many channels, making it very fast and stable. More and more laptops and phones have a 5G WiFi card due to its ease of use and reliability.

Standards are also very important to note. Different routers support different standards from which the resulting connection speed is derived. As an example, we can say:

• 802.11b is one of the first standards of the original 802.11 protocol. It uses 2.4GHz bandwidths and offers up to 11MB/sec. Despite it's age, it's still used extensively today.
• 802.11g is a newer version of the 802.11b standard broadcasted on the same frequency. Compared to its predecessor, it offers up to 54MB/sec.
• The physical speed of the 802.11ac standard, which is only found in 5GHz, is really fast and exceeds 1GB/sec. You need to have the appropriate router to be able to use this speed.
• However, the 802.11ad standard is the fastest. In addition to the 2.4GHz and 5GHz bands, it also uses the 60GHz band. It achieves speeds of up to 7GB/sec. However, this standard is still waiting for its larger expansion.

Standards are constantly evolving to offer a more stable and faster connection.
