Reply To: Spreading in UMTS – Redundancy vs Capaci

3G / 4G / etc.. Networks are bandwidth and power intensive solutions.

The Radio access is based on WCMDA, OFDMA, MIMO-OFDMA, etc..

Spread Spectrum is at the core and uses techniques like DFT, FFT, etc..

You have to make the investment with the extra bandwidth and the required power.

3G and onwards are Power / Bandwidth Radio solutions. 2G / TDMA is good for Voice based applications. Multimedia / (I)IOT applications require a core spread spectrum access.
