2.4 GHz vs 5 GHz
When logging into a WiFi network and presented with two bands: 2.4GHz and 5GHz — you might have the following questions:
The answer to the last question can clarify the difference between 2.4GHz and 5GHz bands. Even though they are different frequencies, supported routers can broadcast on both simultaneously, and some can switch between the two bands during operation. Blink devices; however, will ONLY connect to 2.4GHz bands.
A dual-band router is any wireless internet router that sends out a signal on both 2.4GHz and 5GHz frequencies. Routers have features that vary based on manufacturer and model. Most dual-band routers automatically broadcast on both bands without any additional configuration, which is why it may not be obvious there are two bands.
The main differences between 2.4GHz and 5GHz bands are the speed and range of their networks. A 2.4GHz band transmits farther and can penetrate building materials better with lower power transmission. A 5GHz band; however, can send more data. 5GHz should not be confused with 5G networks that mobile devices use for data transmission.
Many other devices commonly found in homes, such as microwave ovens and garage door openers, also operate on the 2.4GHz band. This can cause interference and reduce speeds. In addition, placing your devices behind dense building materials such as brick, stone, concrete, steel, and aluminum can interfere with signal strength, even when connecting on 2.4GHz.
With the technological advancement of routers, "band steering" is becoming more common. Routers with this feature use the same Wi-Fi network name (SSID) and password for both 2.4GHz and 5GHz bands, allowing you to join a single network and receive the advantages of both frequencies.
Note: Blink devices ONLY connect to 2.4GHz bands, even when bands are merged on your router.
