FREQUENCY GUIDE 2013
Introduction
Are you ready for the Digital Dividend Restack?
Wireless microphones and in-ear monitoring systems that operate in the soon to be
reallocated digital dividend spectrum (694-820MHz) will become illegal to operate after
the 1st of January 2015. Most of the major manufacturers, including Shure, Sennheiser,
AKG, Audio Technica, Bosch and Audio Telex, will have products that operate legally
below 694MHz. In addition to this all TV allocations are being restacked onto a “block
allocation” structure commencing mid-2013. During this time allocations will vary
from city to city, month to month. Wireless audio users must stay informed of these
changes. This brochure should be your starting point to help with the changes. The
website www.readyfordigital.com.au is intended to be your main reference tool during
the restack period.
What is changing?
Australia is in transition from Analogue to Digital TV transmission. Digital TV transmission is much more spectrally
efficient than analogue, thus once transition is complete a significant portion of the spectrum currently allocated
to TV broadcast (694-820MHz) will become “surplus to requirements”. This surplus spectrum, referred to as the
DIGITAL DIVIDEND, will be reallocated to Telecommunications service providers to enable next generation 4G mobile
data services. As a result, wireless audio devices must also vacate this part of the spectrum to make way for the new
services.
Additionally the TV services will be restacked into a block structure in the remaining 520-694MHz broadcast
spectrum. The allocation of these blocks will vary from location to location, making it imperative that operators of
wireless audio devices research the new block allocations in order to coordinate operations.
How will this affect me?
From the 1st of January 2015 the authorised frequency range for wireless audio devices will be reduced from the
current 520-820MHz to 520-694MHz. Older devices that operate above 694MHz in what is colloquially known as “the
700MHz band” must be restricted to operate below 694MHz ONLY. Devices that are not capable of operating below
694MHz may no longer be used after the 1st of January 2015.
What do I need to do?
• Do an audit of your current systems. What frequency range do they operate on now? Are they capable of
operating in the range 520-694MHz?
• Plan to transition out non-compliant products before the 1st of January 2015.
• Research the TV block allocation and confirm products operating below 694MHz are compatible with the block
allocation in locations of interest.

FAQ’s
Do I need a license to operate a wireless microphone or in-ear system in
Australia?
Yes. All forms of radio transmitters must be licensed under Australian law. However, most wireless microphones and
in-ear monitor systems are covered by a class license. All Shure products imported by Jands are covered under this
license. This means that as long as the product meets the relevant technical specifications and you operate within
the conditions of the license document, you do not need to take out an individual license. The license document in
question is called Radio Communications (Low Interference Potential Devices - LIPD) Class License 2000. Issued
by the Australian Communications and Media Authority (ACMA), further details are available on the ACMA website:
www.acma.gov.au.
What is the legal frequency range in Australia?
There are a number of frequency ranges permitted for operation of wireless audio devices in Australia. These are
covered in detail in the LIPD class licence document. The primary and highest capacity band is the UHF TV band.
Allocations summarised as follows;

I heard that some of the 700MHz spectrum was left unsold after the auction.
Does this mean that wireless microphones may be permitted to keep using it?
The digital dividend auction started on the 23rd of April 2013 and concluded on the 7th of May 2013. Only Telstra and
Optus bid for sections of the available 700MHz spectrum, and at the conclusion of the auction two blocks of 15MHz
of spectrum were left unsold (733-748MHz and 788-803MHz). It’s too early to speculate at the possible implications
of this for wireless audio devices. The LIPD has already been modified to restrict operations to 520 – 694MHz from
the 1st of January 2015. It is most likely that the unsold 700MHz spectrum will be re-offered to auction at some future
date. AWAG is in discussion with the ACMA regarding possible temporary access to this part of the band until it is
sold. However it is VERY early days, so don’t pin your hopes on this. Monitor the www.readyfordigital.com.au forum
for updates.
What do the blocks mean?
As part of the digital dividend reallocation all TV transmitter allocations will be restacked into the remaining spectrum;
520–694MHz into blocks. Five blocks of six contiguous TV channels (42MHz) will be created. A block or multiple
blocks will be allocated as required for TV services in each coverage area. Block allocations will vary from area to
area.

Training
Shure Wireless Workbench School
The Shure Wireless Workbench Certification Program is more than an
excellent training course. You’ll also earn 4 renewal units (RUs) toward
InfoComm CTS accreditation through successful completion of the course.
Frequency selection and coordination is critical to the successful design
of wireless microphone and in-ear systems. This will become more so as
the pool of available frequencies diminishes in coming years due to the
digital dividend reallocation. Frequency coordination tasks become more
complex as the number of systems increases, often to the point of requiring
a dedicated RF engineer on large productions.
Shure have lifted the veil on the dark art of frequency selection with the release
of version 6 of Wireless Workbench (WWB6), their software application for
configuration, control and monitoring of wireless audio devices.
Shure Wireless Workbench School is run once a month alternating between
Sydney and Melbourne and occasionally in other capital cities.
This half day course is recommended for audio professionals involved in
the design and / or operation of wireless audio systems. Attendees should
have previous experience with wireless audio systems and be familiar with
technical terms and concepts.
Class sizes are limited. We recommend that you register now to ensure your place at www.readyfordigital.com.au.
