Frequency and Range Overview
The Circle Communication PBX phone system is excellent for smaller offices and home office usage. However, it is not intended for longer ranges than a typical 2.4 GHz phone covers.
Some important points:
- The new 2.4GHz system's signal will penetrate walls better and travel further distances that a 5.8 GHz phone.
- As with all 2.4GHz phones, there will be competition with wireless computer networking signals. So, it is not recommended for an environment which operates a wireless network.
You will achieve the best results when there is a maximum of one floor between the base and receiving units and just a few walls within a 3,000 sq ft area.
Moving the base two stories away, adding more than a few walls or traveling more than 3,000 sq ft will cut down on the signal strength.
The nature of how various frequencies move in open air and through materials is an important factor in understanding how to recommend a cordless telephone system.
In open space (free field), all cordless devices are limited to the power that can transmit and be received for 1000ft. That is why regardless of frequency, all cordless devices are rated at a range of 1000ft.
However, how frequencies work inside a building or from the inside to the outside of buildings is very dependent on the band utilized by a system. The lower the frequency, the better that frequency is at penetrating walls or bending around corners. This means that 2.4G is better than 5.8G. To use a simple example, when you hear music in a building it is the bass that penetrates. The higher frequencies get absorbed or reflected.
The Circle system specializes in the smaller environments, and is not designed for large office buildings or for homes with several floors and many dense walls. The range of the phone system is not compatible when large quantities of mason or concrete construction is used.
