Australia Frequencies

Australia is a large country that is served by several mobile phone network providers. If you want to know how to block mobile phone signals in the country, it is important to understand the frequencies used by these providers. In this article, we will take a look at the main network providers in Australia, and the frequency bands that need to be covered in order to effectively block mobile phone signals.
Mobile communications in Australia is an issue that needs your attention. There are not many towns in this government compared to other governments, so this place is immediately involved in the growth of mobile communications. Australia is located on a separate continent, so most of the settlements are directly near the ocean.
Regulatory agencies ACMA is the lead regulator for radiocommunications equipment (including signal jammers) in Australia. ACMA is responsible for enforcing the rules and regulations relating to the use of radiocommunications equipment and issuing licences for its use.
Mobile operators in Australia Therefore, there are only three mobile operators in Australia that offer their services. Other networks use the capabilities of these providers, so they operate on the MVNO principle. We will provide you with more detailed information about mobile operators in Australia.
Telstra is Australia's largest telecommunications company and the country's oldest operator. With over 40% of the mobile market share, it is the telecommunications company with the widest network coverage and the largest number of users in the country.
Here are the details about Telstra:
Telstra's network and frequency band support
3G network (UMTS/HSPA):

• Frequency band: 850 MHz
• Destination: The 3G network is scheduled to be shut down in mid-2024, at which time resources will be reallocated to 4G and 5G.

4G LTE Network:

Frequency band:

• 700MHz (Band 28)
• 850 MHz (Band 5)
• 1800MHz (Band 3)
• 2100 MHz (Band 1)
• 2600 MHz (Band 7)

Coverage: Covers most of the country, including cities, suburbs and remote areas.

5G Network:

Frequency band:

• 3.5 GHz（n78）
• 26 GHz（n258）

Another major operator is Optus. It is the second largest telecommunications operator in Australia and is affiliated to Singapore Telecommunications Group (Singtel). With its extensive network coverage and competitive prices, Optus competes fiercely with companies such as Telstra in the Australian telecommunications market.
On or about September 22, 2022, Optus systems suffered a major cyber attack, resulting in a significant breach of personal information of current and former customers.
An unexplained issue caused a nationwide outage of Optus mobile and fixed internet services in the early hours of November 8, 2023. The outage directly affected more than 10 million customers, including government services, hospitals and businesses.
Optus network frequency bands and coverage

3G: 900 MHz (Band 8)

4G LTE：

• 700 MHz (Band 28): Provides wide-area coverage, suitable for remote areas
• 1800 MHz (Band 3): Suitable for high-speed transmission in urban areas
• 2300 MHz (Band 40): For high data traffic areas

5G frequency bands:

• 3.5 GHz (Band n78): for high-speed coverage in urban centers
• 26 GHz (Band n258): supports extremely high-speed short-range communications

Coverage: Optus' network covers most cities and suburbs in Australia, and coverage in remote areas is still expanding. Special attention should be paid to the high quality of service and reliable coverage. At the same time, poor performance within the premises should also be noted. In many buildings, mobile communications stopped working. This is because many residents refuse to have a tower next to their buildings.
Another well-known mobile company is Vodafone. Vodafone Australia is one of Australia's leading telecommunications companies, occupying an important position in the Australian market with its price advantages, international roaming services and enterprise solutions. Although slightly inferior to Telstra in network coverage, Vodafone became a brand of TPG Telecom Limited after completing the merger with TPG Telecom in 2020. This merger strengthened Vodafone's competitiveness in the Australian market and is the third largest wireless operator in Australia.
Network frequency band and coverage 3G：

• 850 MHz (Band 5)
• 900 MHz (Band 8)

4G LTE network bands:

• 700 MHz（Band 28）
• 1800 MHz（Band 3）
• 2100 MHz（Band 1）
• 2600 MHz（Band 7）

5G network frequency band:

• 3.5 GHz（Band n78）

Vodafone has a high 4G coverage in major cities, and its 5G network is still expanding rapidly.
Regional providers and MVNOs In addition to these major operators, there are mobile virtual network operators (MVNOs) such as Amaysim, Boost Mobile and Aldi Mobile, which lease infrastructure from Telstra, Optus or Vodafone to offer their own mobile plans. These providers use the same frequency bands as their host networks.
The frequency bands that need to be covered to block mobile phone signals:
In order to effectively block mobile phone signals in Australia, it is necessary to cover the frequencies used by the major network providers. The following frequency bands should be considered:

Network	3G Frequencies	4G Frequencies	5G Frequencies
Telstra	850 MHz	700, 1800, 2100, 2600 MHz	3.5, 26 GHz
Optus	900 MHz	700, 1800, 2100, 2300, 2600 MHz	3.5, 26 GHz
Vodafone	850, 900 MHz	700, 1800, 2100, 2600 MHz	3.5 GHz
Vodafone	850, 900 MHz	700, 1800, 2100, 2600 MHz	3.5 GHz

Using jamming devices or cell phone jammers that cover these frequencies can effectively block cell phone signals in the target area.
