For those who want to know more about the two types of wireless audio signal transmission to portable speakers, we decided to present some data here. We will analyze the Wi-Fi method compared to Bluetooth, discussing the advantages and disadvantages for each.
We will not go into very specific details regarding the technology used, but we will try to keep the simple descriptions of each data transmission method, so that we can be easily understood by all readers.
General operating principles
For the Bluetooth interface, radio waves are used to transmit data on a common frequency between the source gadget and the portable speaker. There are 79 frequency channels that can be used in this regard, and this means that if in a space there are two devices connected via Bluetooth, many other pairs of devices can operate together, without their frequencies overlapping.
It is necessary to have a security method between them, to prevent compromising the connection. For this reason, a password will be used to connect them. Also, installing antivirus applications on the phone, tablet or laptop you use for streaming music is a great idea.
In the case of the Wi-Fi interface, 2.4 GHz and 5 GHz bands are used to transmit data also through radio waves, everything being coordinated by the router. The two frequencies are divided into multiple channels to eliminate interference and excessive traffic.
The performance advantages are accompanied by the disadvantage of the need for a wi-fi hotspot in the area – in other words, only the source gadget and the portable speaker cannot be used when you want this type of connection.
