Innovations For Wireless Audio Systems

How to expand and speed up the wireless connection? Here are new innovations that will take hold over the next few years.

Wireless connections via Bluetooth or wi-fi are gaining ground in technology, slowly replacing the need to use cables to connect devices. The demand of users is always higher, for many in fact the purchase of a particular technological product is influenced by the presence or absence of Bluetooth.


Wireless, available for some years, has seen an ever-increasing interest with the arrival of fast connections to the web and the conquest of the market by smartphones, tablets, notebooks, Macs and tablets. These portable devices need a wireless connection to access the network, in fact now all the premises and businesses have a wi-fi connection that allows users to access the web at any time.


It is a sign of a world in continuous acceleration, if before it could be considered crazy to stay with your head on the phone screen for hours even in a public place, now it is on the agenda. Smartphones and tablets have become an integral part of our life as well as the web, now reachable from practically any point in the world.


Of course, there are many who criticize the constant ‘presence’ of the web at any time of the day, in fact it seems to be never really alone and to live in constant waiting for a message on Whatsapp, a like on Facebook or


Not just wireless

The cable internet connection is not entirely gone, in fact in the home it is still used in PC gaming due to the data exchange speed higher than wireless.


Of course, this implies the proximity of a router or modem to your PC, because otherwise you end up cluttering the environment with one or more Ethernet cables. The cable connection is also suitable for downloading large amounts of data in a few seconds, since the wi-fi ones still cannot reach this speed. However, the increasingly strong presence of content streaming will require the creation of increasingly powerful wi-fi connections in the near future, especially to be able to take advantage of particular services, such as video games, another media that is winking at the streaming.








However, cables create clutter, dust and also the potential risk of power failures or short circuits. In fact, when you have different appliances such as televisions, PCs, Blu-Ray players and game consoles, your desk and TV cabinet can become real cable tangles. While video connections still require HDMI cables to get to the highest resolutions, it seems that some steps are being taken in the audio field.


In fact, Bluetooth connectivity for streaming music from various devices has already established itself on the market for several years. Just think of headphones, speakerphones or speakers that can connect to your smartphone without the need for an internet connection or wires. Despite being quite stable and fast, especially in the latest versions, Bluetooth remains inferior to the cable connection in terms of data transfer stability.


Audio quality without wires

For this very powerful speakers and home theater systems are still forced to use cables and wires for connection. Recently, however, several companies are looking for ways to get around the problem by creating more efficient wireless and Bluetooth connection systems, especially with regard to television entertainment. Home theaters 2.1 consisting of soundbars and subwoofers will very soon switch to wireless configurations, being only two devices that are easier to manage in the exchange of data. The problem remains for 5.1 systems with as many as four speakers that must communicate with each other to create the original surround effect. 


An association of audio manufacturers called WISA (Wireless Speaker and Audio Association) is working to find a decisive solution to the problem. Not only do they want to create high-end Bluetooth speakers, but also improve the quality of transmission with the aim of achieving the same achievable with cables.


On the other hand, a 5.1 Home Theater system involves the use of lots of cables to be arranged around the room, which makes them really impractical. In fact, to be able to enjoy the audio of the cinema, at the moment we are forced to devise every one in order to hide the cables from view and not make them an obstacle to the passage.


WISA has worked on 24-bit transmissions on 48kHz / 96kHz frequencies that guarantee twice the quality of audio CDs, testing it on 7.1 systems that include side speakers as well as front and rear speakers. The results obtained seem to be more than positive, with a better reception capacity than the common Bluetooth.


The home theater of the future

At the moment the association has already aroused the interest of important brands such as LG, Microsoft, Harman Kardon, JBL and Pioneer so it is likely that we will soon see new systems that integrate these new technologies for the transmission of sounds.


WISA also presented a USB transmitter to connect speaker wirelss to each other, also stated that the devices will be equipped with auto-configuration and very easy to use.


This all sounds fantastic and would make 5.1 or 7.1 systems even more accessible to the general public. The absence of cables would allow you to set up a Home Theater even in a small room, perhaps combining it with your PC rather than the TV. It remains to be seen what the selling price of these new home theaters will be, which will certainly be proportional to the production costs.


This could also mean further lowering the prices of cable systems, which may only be good for any movie lover who wants to have surround sound at home, but only held back by the still high prices in the market.
