13. Why is there a need for an interoperability and compliance test specification?
The CTS will be managed by the agent of the association, WiSA, LLC, under
the guidance of the WiSA Advisory Board and the Technical Advisory Committee.
14. What is driving the need for standardization in high definition wireless audio?
Consumers want HD wireless surround speakers to match the HD video quality
of their HDTVs, Blu-ray players, and gaming consoles; however, until now
they had limited options to realize this vision. With WiSA-certified products,
consumers will be able to outfit their home entertainment systems with
speakers and components from any participating vendor with the assurance
that the devices will interoperate with each other and provide the highest
quality HD wireless surround sound. Products featuring the WiSA logo have
been compliance tested, thus ensuring interoperability with other WiSA-enabled
15. What do consumers need to know about the underlying technology and the compliance/logo program?
HDTVs are getting thinner and it is becoming increasingly difficult to
incorporate the latest electronic advances into such thin displays. We
expect that eventually most of the electronics will be external to the
display. The first to go is the audio, since there is very little room
for quality speakers in today’s thin displays and HDTV manufacturers know
they need to provide an audio alternative. Additionally, since cost is
a significant consideration, some manufacturers will offer external sound
bars which will satisfy some consumers, but there remains a strong need
for a high quality audio alternative. All of these developments have created
an inflection point in the market, and manufacturers are looking to the
WiSA Association to create a standard for wireless audio interoperability
that will support a long-term product strategy for the successful development
of high quality, wireless audio products.
16. How will WiSA technology change the user experience?
The underlying technology takes advantage of a rarely used frequency range
called the U-NII band which operates between 5.2 and 5.8GHz. This frequency
range allows for the transmission of uncompressed, cinema-quality audio
that is unattainable with other wireless technologies. Additionally, because
of the special requirements on how this band is to be used, it allows
for an interference-free user experience.
The WiSA logo program ensures that participating products have been compliance
tested, thus ensuring interoperability with other WiSA-compliant CE devices.
Manufacturers will submit their WiSA-enabled products to the Association
and products that have passed compliance and interoperability testing
will feature the WiSA logo. Consumers evaluating WiSA-compliant products
will have the choice to buy components from different brands, knowing
that they will interoperate seamlessly right out of the box. This is the
confidence provided by the WiSA logo.
17. Can you give a brief overview of the certification process?
Working with WiSA-compliant products gives consumers a migration path
for adding additional speakers to upgrade their home audio system. For
example, a consumer might start with a WiSA certified sound bar for their
flat screen television and then add a WiSA subwoofer. A year or so later,
that same system can be easily upgraded to 5.1 or a 7.1 surround sound
by simply more surround sound speakers. There is no need to replace the
entire system; consumers can keep the original transmitter, sound bar,
and subwoofer and integrate them seamlessly into their new system. Being
able to outfit a home entertainment system with WiSA-compliant speakers
and components from any participating vendor gives consumers not only
the choice to select components based on their individual preference,
but also provides the assurance that the devices will interoperate with
each other and deliver the highest standard in HD wireless surround sound.
18. Is there a limit to the number of channels? 9.x and 11.x receivers are coming onto the market now. Will WiSA support these?
The manufacturer builds their equipment according to the WiSA Compliance
Test Specification (CTS). They then test- run their own equipment through
the CTS and when the product is ready, the manufacturer fills out a Capability
Declaration Form, attaches it to the equipment and sends it to a WiSA
Authorized Test Center for certification. After passing the certification,
the member will receive a Certificate of Compliance and the product will
be licensed to display the WiSA logo.
19. Which approach to the “sweet spot” has been adopted by WiSA?
There is currently a limit of 8 channels. The maximum configuration is
7.4 (4 subs share 1 channel). The WiSA technology roadmap calls for increasing
the number of channels and for an increase in the bit rates as well. The
WiSA Association will announce changes in the maximum configuration as
soon as they become available.
20. My receiver has room optimization. Won’t that conflict with WiSA’s sweet spot algorithm?
WiSA technology delivers a single sweet spot where the levels and delays
are optimized. This can be changed instantly to any arbitrary location
using an onscreen display, a remote control fitted with an ultrasonic
transducer, or perhaps a mobile app using a smartphone as a remote control.
21. Do WiSA-compliant speakers require line-of-sight or can the technology transmit through walls and floors?
It is not necessary to use the sweet spot technology when implementing
a WiSA-based home audio system. The sweet spot can be fixed at a single
location and the receiver can use its own algorithm.
22. 802.11a (common on Apple devices) and WHDI use the 5 GHz band. Will
I have interference issues if I use 802.11a or WHDI devices near my WiSA-enabled
home audio system?
As with most wireless radios, a WiSA-compliant system is designed to operate
in the Unlicensed National Information Infrastructure (U-NII) frequency
band; it does not require line-of-sight nor does it go through walls and
floors. The U-NII band was selected to maximize channel availability and
thus eliminate interference.
Products built without the ultrasonic transducers do not require line-of-sight;
this functionality is based on the feature set designed in by the manufacturer.
However, to take advantage of the sweet spot location and auto calibration
features, line-of-sight is required.
WiSA certification guarantees that the equipment will operate within a
minimum of 30’ x 30’ space. This is done to set realistic customer expectations,
unlike some wireless radios that claim a huge range and fail to work.
While not currently supporting multi-room settings, we are actively looking
at the requirements for multi-room applications.
23. What is Dynamic Frequency Selection (DFS)?
Having other devices nearby that also use the 5 GHz band will not affect
the performance of a WiSA-enabled home audio system as WiSA technology
can seamlessly switch to another frequency within the 5 GHz band. The
5 GHz U-NII spectrum utilized by WiSA technology has up to 24 channels
available that are constantly monitored for interference using the Dynamic
Frequency Selection (DFS) sub-band between 5.2 and 5.8 GHz. When interference
is detected, the next channel, having been monitored for over one minute
and confirmed for accessibility, is ready to go and WiSA-enabled devices
switch seamlessly to that channel, without the user ever noticing or the
audio experience being affected.
24. Will I need a new A/V receiver to use WiSA speakers?
The Dynamic Frequency Selection (DFS) sub-band between 5.2 and 5.8 GHz
is shared with military and weather (aviation) radar. The rule for this
sub-band is that the equipment must use DFS when radar is detected on
a channel and immediately hop to an open channel.
This is inconvenient for computer networking because a channel must be
clear for one minute before use and cannot be reused for 30 minutes after
a conflict is detected. Due to the strict access rules there are only
a few systems that operate in the DFS band as a result and WiSA-enabled
systems are one of them.
Audio is ideally suited for DFS operation since audio requires a steady
stream of data -- not high-speed bursts. Some of the audio transmission
time can be used to look for unused channels. When interference is detected,
the next channel has been monitored for over one minute and is ready to
Using DFS is also good when there is interference from other radios, or
if signal strength is poor for some reason. The system can just hop to
another frequency. This makes it very friendly when co-existing with other
25. Is WiSA-compliant technology just for residential applications,
or does it have commercial applications too? If so, can you provide some
No. Think of WiSA-compliant devices as operating just like speaker wires.
You may not need to use all of the amps on your receiver. Likewise, if
you want to wire your front speakers to your receiver, WiSA-compliant
equipment can provide the connection to your subwoofer, surround speakers
and rear channels.
26. OK, I’m sold. When and where can I buy WiSA-certified products?
Initially the WiSA Association is focusing on home theater. However, WiSA was invited to participate in
Pete Putman’s “AV Signals
Gone Wireless” presentation at InfoComm. We did a
very successful demonstration in a large meeting room to an audience of
professional installers. The Association is gaining more and more interest
from the pro and commercial markets who are also looking for a highly
reliable, interference free, wireless solution.
Besides the quality and robustness of the underlying technology, the InfoComm
presentation demonstrated rapid setup and tear-down for mobile systems,
conference rooms, lecture halls, and meeting rooms. Any place where it
is inconvenient, unsightly, or unsafe to run wires is a good fit for a
WiSA-compliant speaker system. The same goes for business locations that
have concrete walls and floors that may cause installation problems.
There are a large number of systems from multiple manufacturers currently under
development and should be hitting the market in the very near future. One company that has
announced and is shipping an amazing WiSA compliant high resolution audio system is Bang
and Olufsen. They have a selection of speakers, TV’s and other audio components that are
being marketed under the “Immaculate Sound” branding in their product line. Sharp has also introduced a
really interesting WiSA-compliant
wireless high resolution audio player.
Systems will soon be hitting the market at a wide variety of price points and capabilities.
We will update you on all of the new systems and products. Prototype devices are also
featured in the WiSA Association sound room at various expos around the world including
CEDIA, Integrated Systems Europe, and CES.
