Seamless, wireless communications at events of any size are vital for success, but a
new regulation proposed by the Independent Communications Authority of South
Africa (ICASA) could prevent AV and tech professionals in the event industry from
doing this. ICASA regulates the distribution and licensing of frequencies for wireless
communications, including radio microphones, events, in-ear monitoring and wireless
communications devices.

The majority of radio microphones, until now, were required to work within the legal
band of 800MHz range. This is the frequency band that ICASA wants to allocate to cell
phone networks for broadband. For the event industry, this means:

• Smaller bandwidth size to operate on, which results in increased interference

• Replacing 800MHz radio microphones with those suitable for another frequency

“If the industry has a smaller bandwidth for its wireless comms to operate, we will
find ourselves battling with interference, and having to invest in new equipment that
operates in the frequency decided by ICASA,’ advises Gary Billson, head of technical
services at Magnetic Storm. “This could mean the event experience is not as polished
as one would expect.’

The biggest battle will be in the larger cities of South Africa and the international
conference centres running ten events a day with multiple wireless microphones and
communication devices. “What we dub “clean air’ will become a luxury to operate on,
and we will have to get creative in how we overcome this obstacle,” adds Billson.

The Southern African Communications Industries Association (SACIA), has created a
task force to lobby against the change in frequency allocation due to the impact on
the event industry. In a statement, SACIA said: “the AV industry needs to engage in a
formal conversation with ICASA and ensure that they are better informed about the
requirements of the industry sector.’

“Places of worship, Universities and schools will also have to replace their radio
microphones,” adds Billson. “And it’s these non-profit organisations who will face
financial challenges; they cannot afford to replace equipment. ”

Magnetic Storm is one company supporting the dialogue that needs to happen, to
educate, inform and preserve the space dedicated to low-powered communication
devices, and maintain event industry standards.
