IO-link wireless communication

An apparatus for wireless communications, comprising:

• a plurality of radio frequency transceivers each configured to transmit and receive wireless signals at a different one of a plurality of frequencies;
• a splitter electrically connected by a plurality of conductive tracks to the plurality of radio frequency transceivers, each one of the plurality of transceivers connected to the splitter by one of the plurality of conductive tracks, wherein the splitter comprises a 90 degree phase shifter, and wherein a physical configuration of each of the plurality of tracks corresponds to the one of the plurality of frequencies to which the one of the plurality of tracks is coupled;
• and
• a circular polarization antenna operatively coupled to the splitter, wherein the circular polarization antenna is configured to wirelessly transmit the wireless signals received from the plurality of radio frequency transceiver received via the splitter.
