A telecommunication system for processing a plurality of simultaneous bidirectional communications includes a primary station and at least one secondary station using wireless transmissions over one of a plurality of available RF carrier frequencies. Each carrier frequency has an associated predetermined bandwidth which is designed to accommodate one analog voice signal therein and each carrier frequency contains a plurality of time slots. Each bidirectional communication includes transmit (TX) and receive (RX) information signals. The secondary stations include a baseband processor for PSK coding an input signal; a storage means coupled to said baseband processor for storing information; a control means coupled to the baseband processor and the storage means to permit access to the stored information; a filter for performing quadrature sampling of the PSK coded signal; a digital to analog converter for converting the sampled PSK coded signal into an analog signal; and a frequency translator for translating the frequency spectrum of the analog signal to a second frequency spectrum.
