  • Spectrum splitter TDMA

    Spectrum splitter TDMA

    Frequency-Division Multiple-Access (FDMA) splits the channel into two narrower sub-channels that can each carry separate calls. It allows several users to share the same frequency channel by dividing the signal into different time slots. Digital radio offers many advantages over analog, including improved voice quality at greater range, better privacy, sophisticated call-control features, the ability to easily integrate ith data systems, and more. We're now at the beginning of what will quickly become a. TDMA stands for “Time-Division Multiple Access.
