In Part Two of this series on Digital Migration, we discuss Better Capacity.
Part Two: Better Capacity
Regulatory pressures and real-world needs are driving a demand to expand the capacity of the business designated slice of the RF spectrum by leveraging new technology. As it happens, digital two way radio technology is very bandwidth efficient and actually allows two separate "channels" to operate on a single 12.5 kHz frequency, effectively doubling its capacity. (See chart below)
In addition to making efficient use of the RF spectrum, this feature helps minimize licensing costs associated with operational expansion because the additional channels do not require additional frequencies. For a fast growing business that is expanding its radio operations this can mean significant savings while expanding communcations.
In the following excerpt from TDMA TECHNOLOGY, a whitepaper published by Motorola Solutions, the details are explained.
