The 3G Shutdown: What You Need to Know
Telstra and Optus are continually de-commissioning the 3G network across the country. By mid-2024, the entire 3G service is expected to be no longer available. This shutdown will have a significant impact on devices that rely on the 3G network to operate, including security systems that report back to base monitoring stations using 3G alarm diallers.
If you have an alarm system that uses a 3G alarm dialler, it’s necessary to replace it with a 4G device before the service is shut down. Failure to do so could mean that your alarm system will no longer be able to communicate with the monitoring station, putting your property and assets at risk. Make sure you contact our experienced team at Guztech before this shutdown complete to avoid any down time on your security systems.
The Significance of Upgrading from 3G to 4G
When changing devices that are utilising External or High-Gain Antennas, it’s important to upgrade the antennas as well. Antennas are not universal. They are tuned to operate on set frequencies. Using a 3G antenna on 4G devices could, in fact, damage the device with reflected power returning to the output of the device. 4G antennas should be used to ensure there are no future operational issues.
In addition to upgrading the antennas, 4G devices also require two antennas to operate effectively, requiring Primary and Secondary Antennas. Whereas 3G devices only required a single antenna. This means that if you have an existing 3G alarm system that uses a single antenna, you will need to install a secondary antenna for the new 4G device.
The Impact of Upgrading Antennas with 4G Devices
Upgrading the antennas on your alarm system to 4G-compatible antennas will provide several benefits. Firstly, 4G antennas are more efficient and provide better signal strength and coverage than 3G antennas. This means that your alarm system will be more reliable and less prone to communication failures.
Secondly, 4G antennas are capable of handling higher data speeds, which means that your alarm system will be able to transmit data faster and more efficiently. This is particularly important for alarm systems that transmit high-resolution video footage or other data-intensive information.
Finally, upgrading your alarm system to a 4G device with 4G antennas will ensure that your system is future-proofed for the next few years. With the 3G network being shut down in the near future, it’s important to invest in a system that will continue to operate reliably and efficiently for years to come.

The Importance of Professional Installation for 4G Upgrades
When upgrading your alarm system to a 4G device and antennas, it is crucial to emphasize the importance of professional installation. While it may be tempting to attempt the upgrade yourself, improper installation can lead to significant issues and compromises in security.
Professional installers have the expertise and knowledge to ensure that the 4G device and antennas are correctly installed and integrated into your existing security system. They can assess the optimal antenna placement for maximum signal strength and coverage, minimizing the risk of communication failures.
Moreover, professional installers understand the intricacies of configuring and programming the new 4G device to seamlessly communicate with your monitoring station. They can troubleshoot any compatibility issues, perform necessary software updates, and thoroughly test the system to guarantee its reliability and effectiveness.
Attempting a DIY installation without proper understanding or experience may result in subpar performance, leaving your property vulnerable to security breaches. It is worth investing in the services of a reputable security system provider like Guztech to ensure a smooth and successful transition to 4G.
Remember, the 3G shutdown presents an opportunity to not only upgrade your alarm system but also enhance its overall performance and capabilities. By entrusting the installation to professionals, you can have peace of mind knowing that your security system is ready to meet the demands of the future while safeguarding your valuable assets.
The 3G Shutdown: Conclusion
In conclusion, the 3G network shutdown is imminent, and it’s essential that alarm system owners upgrade their systems to 4G devices and antennas to ensure that they continue to operate reliably and efficiently. By making this investment now, you can future-proof your system and enjoy peace of mind knowing that your property and assets are protected. Don’t delay, contact Guztech today and let their experienced team guide you through the upgrade process to ensure the highest level of security for your property.
