One of the secret sauces in any communications network is effective synchronization. Things that we take for granted in our everyday lives like call hand-off between cellular sites can’t be achieved without a frequency-synchronized network.

Multiple Cambium Networks access points stationed on one tower effectively use limited spectrum through GPS synchronization

A synchronized network is also essential for network planners as they design their networks to manage spectral efficiency to leverage and re-use available frequency channels, maximize available throughput and ensure end-user satisfaction.

Here’s an example that showcases the benefits of a synchronized vs. non-synchronized networks: Let’s say you’re a service provider operating in a five-square-mile (~13 square kilometers) greenfield environment using 45 MHz of available spectrum.You could expect to see 400 Mbps of data availability in that region vs.150 Mbps with a non-synchronized network.  In such a scenario, you could also expect to serve two to four times the number of users with the synchronized system.The reason for this performance difference is that in a synchronized network, you can run four sectors on two channels.  With no synchronization, you can only use one of the channels.Synchronization helps to mitigate inter-cell interference and make best use of the available spectrum in the area.

In a noisy environment with limited spectrum, a GPS-based solution is key to ensuring maximum performance from your system.   Spectrum, as we all know, is a finite resource and we need to be as efficient as possible with what we have available.
