Abstract

Mobile Networks using Orthogonal Frequency Division Multiplex (OFDM) and or spread spectrum modulation and demodulation techniques process in mobile devices spread spectrum signals into OFDM signals. A first mobile device receives and demodulates a spread spectrum modulated signal into a baseband spread spectrum signal and processes the baseband spread spectrum signal into a first OFDM signal. The first OFDM signal is transmitted to a second mobile device. In the second mobile device the received first OFDM signal is demodulated and processed into a second OFDM signal. The second OFDM signal is transmitted in the mobile network. Alternatively, the first mobile device receives, instead of a spread spectrum signal a modulated OFDM signal. The mobile device has a motion detector which generates a motion detector signal for control of the mobile device. The mobile device has a heart rate sensor and measures the heart rate.
