However, coverage remains concentrated in urban and suburban areas, with regional and remote Australia still primarily reliant on 4G or satellite connectivity.

Spectrum Allocation

The Australian Communications and Media Authority (ACMA) has allocated various spectrum bands for 5G services:

• mmWave (26 GHz): High-capacity, short-range bands ideal for dense urban areas and venue-specific broadcasting applications
• Mid-band (3.4-3.7 GHz): Balancing coverage and capacity, these bands are crucial for most broadcasting applications
• Low-band (700/850 MHz): Provides wider coverage but lower capacity, important for regional broadcasting

This multi-band approach enables different broadcasting use cases depending on location and specific requirements.

Transforming Live Event Coverage

5G is already changing how Australian broadcasters approach live event coverage:

Wireless Camera Systems

Traditional broadcast cameras typically require dedicated radio frequency links or wired connections, limiting mobility and flexibility. 5G enables:

• Fully wireless high-definition and 4K camera systems with minimal latency
• Greater camera mobility throughout venues without complex infrastructure
• Reduced setup time and production costs for event coverage

Several Australian sports broadcasters have begun implementing 5G-connected cameras for coverage of cricket, AFL, and rugby matches, allowing for innovative angles and in-game perspectives previously impractical with traditional broadcast setups.

"5G wireless cameras have transformed how we cover live sports. We can now place cameras in locations that were previously impossible or prohibitively expensive to reach, giving viewers unprecedented access to the action."
