Sub-GHz Device Benefits
Sub-GHz, sometimes called sub-1-GHz, refers to the radio frequencies that fall below 1 GHz on the electromagnetic spectrum. These frequencies are significant in the wireless industry due to their unique characteristics and advantages.
Longer Range
Firstly, sub-GHz signals possess excellent broadcast capabilities, allowing them to travel over long distances and penetrate obstacles such as walls and buildings more effectively than higher frequencies. This characteristic makes sub-GHz technology well-suited for applications that require wide coverage, such as smart cities, industrial automation, agriculture and utilities.
Robust and Reliable
Sub-GHz frequencies also offer improved robustness and reliability in challenging environments. They are less susceptible to interference from other wireless devices that operate at higher frequencies, providing more stable communication. This makes sub-GHz technology optimal for applications that demand high reliability and security, such as wireless sensor networks, remote monitoring and control systems.
Efficient Power Consumption
Lastly, sub-GHz solutions often have lower power consumption compared to higher-frequency alternatives, resulting in extended battery life for wireless devices. This energy efficiency is particularly valuable in applications where frequent battery replacement or recharging is impractical or costly.
In summary, sub-GHz frequencies play a crucial role in the wireless industry by enabling reliable, long-range communication with excellent penetration capabilities and low power consumption.
The 315 MHz and 433 MHz bands are used globally, but the other bands are only supported in specific regions. Here are some of the most popular sub-GHz bands and frequencies used around the world:
- 868 MHz: primarily used in Europe
- 915 MHz: primarily used in North and South America
- 920 MHz: primarily used in Asia
- 779 MHz: primarily used in China
