Abstract
Antenna system connectable to a base station, the antenna system comprising a digital radio unit connectable to at least one antenna element, wherein the digital radio unit comprises: at least one micro radio for receiving/sending digital radio signals having a digital down-converter/a digital up-converter and a digital signal converter. The at least one micro radio converts the digital radio signals to analogue RF (radio frequency) signals and vice versa. The at least one micro radio has at least one hub for processing digital radio signals and control signals and for routing said digital radio signals and control signals via at least one serial link and at least one interface. The at least one serial link is provided between the at least one hub and the at least one micro radio.

An antenna system connectable to a base station, the antenna system comprising:
- a plurality of antenna elements forming an antenna for transceiving multi-frequency carrier signals;
- a digital radio unit connected to at least one of the plurality of antenna elements, wherein the digital radio unit comprises:
- a plurality of digital micro radios for receiving and sending digital radio signals, wherein each of the plurality of digital micro radios is connected to a respective one of the plurality of antenna elements, each of the digital micro radios having a digital down-converter and a digital up-converter and a digital signal converter;
- whereby each of the plurality of micro radios converts the digital radio signals to analogue RF (radio frequency) signals and vice versa;
- and
- a plurality of hubs for processing digital radio signals and control signals and for routing said digital radio signals and control signals via a plurality of digital links and a plurality of interfaces, a respective one of the plurality of digital links being provided between a respective one of the plurality of hubs and a respective one of the plurality of micro radios,
- wherein each of the plurality of hubs comprises a frequency multiplexer and demultiplexer unit for up and down-converting base band signals to and from sub-carrier frequencies;
- a sample rate converter for adjusting sampling frequency of the frequency multiplexer and demultiplexer.
