Wireless Systems- are you Digital Dividend Ready?

Is your Wireless Microphone System Legal?

From 11 March 2015 radio microphones will no longer be permitted to operate in the 698- 806 MHz frequency range (the 700 MHz band) of the radio spectrum. Radio microphone users who currently operate within that band will need to either retune their existing equipment or, if that is not possible, replace their existing equipment.  From 11 March 2015 radio microphones must operate within the frequency ranges, 502-606 MHz and 622-698 MHz.

Our Line 6 Digital Wireless systems are 2.4GHz Systems which are not in these frequency ranges which makes them ideal for use nationwide. You can view the Line 6 Digital Wireless range here...

2.4GHz Broadcast — License-free, Worldwide

You may have noticed that some wireless microphones come with FCC warning labels. Line 6 digital wireless systems, including XD-V55, don’t need "FCC Consumer Alert" stickers because they're fully FCC compliant. XD-V digital wireless operates in the 2.4GHz ISM band, which avoids interference from TV broadcasts, white space devices, cell phone towers and other transmitting devices. XD-V55 systems ensure peace of mind and the most reliable operation worldwide, from Hollywood to Tokyo.  Worried about interference caused by Wi-Fi and Bluetooth® devices that operate in the 2.4GHz ISM band? Line 6 digital wireless systems use uniquely addressed and encoded digital transmission technology, so your signal will travel from transmitter to receiver free of interference.

What frequencies can radio microphone users operate on in the future?

From 11 March 2015 radio microphones must operate within the frequency ranges, 502-606 MHz and 622-698 MHz.

The specific frequencies available for radio microphones in any particular area will depend on the frequencies used by television in that area. Radio microphone suppliers should be able to provide advice on the most suitable frequency range for specific devices, depending on where they will be used. From time to time there may be changes to digital television services that may affect the frequencies that can be used by radio microphones in an area. We therefore recommend that users purchase radio microphones capable of being tuned to different frequencies rather than single frequency devices.

There are also other frequency ranges that may be suitable for use under the General User Radio Licences for Short Range Devices (GURL-SRD). However, many of the frequency ranges available in GURL-SRD are shared with other users.

When are the changes happening?

Suppliers of radio microphones are not be permitted to sell or supply radio microphones that operate in the 700 MHz band. This ban took effect on 1 January 2014

From 11 March 2015 it will be not be permitted to operate radio microphones in the 700 MHz band.

What do radio microphone users need to do to prepare for the changes?

If a current radio microphone operates on a frequency in the 698-806 MHz frequency range then it needs to be retuned to a permitted frequency (502-606 MHz and 622-698 MHz). Check the manual or contact the supplier for help with this process. If the radio microphone cannot be retuned then it will need to be replaced.

How do I know what frequency a radio microphone currently operates on?

Have a look on the radio microphone and its receiver for any markings that indicate the frequency it operates on. Also have a look through the user manual. If unsure exactly what frequency the radio microphone is operating on talk to your supplier.

Why is the frequency range 606-622 MHz unavailable?

The 606 – 622 MHz frequency range is allocated for the Māori Television Service. The management rights for this frequency range are controlled by Te Putahi Paoho. This means that the Ministry of Business, Innovation and Employment (MBIE) does not have the ability to grant a general user licence (or other licences) relating to these frequencies.

What can be done with old equipment?

We offer trade-in deals on Shure, AKG & Sennheiser Wireless systems. Radio microphones can also be recycled. There are a number of e-cyclers located throughout New Zealand, click on the links below, or speak to your local council, to find an e-cycle site near you: (Auckland) (NZ wide) (Wellington) (Auckland, Christchurch and Wellington) (Wellington) (Auckland)

What do radio microphone users need to know when purchasing new equipment?

It is recommended that when new equipment is purchased it is flexible, meaning that it can be used on the widest possible frequency range. It must not operate in the 606-622 MHz or 698-806 MHz frequency range.

When is the best time to replace equipment?

If a radio microphone cannot be retuned then you will need to purchase new equipment prior to 11 March 2015. It is recommended that you purchase new equipment as soon as is practicable.

What impact does digital TV have on radio microphone users?

Digital television is the primary user of the radio spectrum located within the frequency range 502-606 MHz and 622-698 MHz. A radio microphone user operates under a General User Spectrum Licence, on a non-interference secondary basis, and must work around broadcast television services utilising the unused channels and spaces in the spectrum.

The frequencies used by digital television vary from area to area and therefore frequency ‘gaps’ for radio microphones will also vary from area to area.

Television usage may increase over time as new services are provided. Therefore radio microphones that can be used on the widest possible frequency range are recommended.

What impact does 4G mobile broadband have on radio microphone users?

4G services using the 700 MHz band may begin during 2014. It is therefore possible that radio microphone users may experience interference from, or create interference to, 4G services before 11 March 2015. As radio microphones are the secondary user they must be turned off if they are creating interference to a primary user. As was previously the case, radio microphones are not protected and may receive interference from the primary service. Users will need to change frequencies if this happens.

What will happen if a radio microphone is operated within the 700 MHz band after 11 March 2015?

Compliance action may be taken against a user of a radio microphone who continues to operate it on the 700 MHz band or other non-permitted frequencies from 11 March 2015.
