2GHZ Versus Sub-Gig (GHz) Frequencies:
Sub-GHz frequencies provide superior reliability and range compared to higher frequencies, making
them perfect for consistent communication across vast distances or in difficult conditions. Devices
operating in the sub-GHz range, which refers to frequencies below 1 GHz, can transmit signals over
significant distances and can penetrate physical barriers such as walls and buildings more effectively.
Additionally, these frequencies experience less interference compared to those in the heavily congested
2.4-GHz band, which is commonly used by wireless devices.
In the United States, the 900 MHz band is a versatile frequency range that is utilized by various services,
with the FCC overseeing its allocation and regulation.
In the European Union, the 868 MHz frequency is designated by ETSI as the Sub-Gig frequency.
In summary, if an application demands high data rates and more bandwidth in urban or densely populated
areas where interference management is feasible, the 2.4 GHz frequency is a suitable choice. On
the other hand, for applications requiring long-range communication and better obstacle penetration,
particularly in rural or industrial settings with fewer regulatory constraints, a sub-GHz frequency (<1
GHz) is a better option.
Installation Recommendations:
With the many factors that affect and/or interrupt a wireless signal such as walls, glass, metal, objects,
and people, it is highly recommended to:
•
Install devices a minimum of 9.8 ft. (3m) above audiences and/or ground level where practical.
•
Adjust the wireless antenna in a vertical upright position
Position devices in direct line of sight of the controlling E-FLY device
•
Careful planning and testing of the selected installation location is critical to ensure optimum and reliable
wireless operation.
