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 CE devices.
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 systaem. 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 from now, that same system can be easily upgraded
to 5.1 surround sound by simply adding 4 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 5.1 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
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 product will be licensed to carry the WiSA
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
the smartphone as a remote control.
21. Do WiSA 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 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
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
24. Will I need a new
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 go.
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 technologies.
25. Is WiSA just for residential
applications, or does it have commercial applications too? If so, can you provide
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.
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
Many projects are in development now. We anticipate several WiSA-enabled product
introductions to be made at CES 2013 in January in Las Vegas. In the meantime, consumers
can check out Advisory board member
Aperion Audio’s Intimus 4T Summit Wireless System which showcases the technology.
