Transmitting/receiving device and method for transmitting data in a radio network

A method comprising:

• at a controller coupled to a switch between a first antenna of a device and a second antenna of the device, receiving an instruction for a transceiver of the device to transmit a first data frame, the switch being configured to couple the transceiver to the first antenna or the second antenna;
• at the controller, in response to the instruction, generating a first control signal for the switch to couple the transceiver to the first antenna for transmission of the first data frame by the transceiver via the first antenna;
• at the controller, determining whether the transceiver has received within a pre-determined time interval after the transmission of the first data frame a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device;
• and
• at the controller, if the transceiver has not received within the pre-determined time interval after the transmission of the first data frame the second data frame, then generating a second control signal for the switch to couple the transceiver to the second antenna for re-transmission of the first data frame by the transceiver via the second antenna.

One or more computer-readable non-transitory storage media embodying logic that is configured when executed to:

• receive an instruction for a transceiver of a device to transmit a first data frame, there being a switch between a first antenna of the device and a second antenna of the device, the switch being configured to couple the transceiver to the first antenna or the second antenna;
• in response to the instruction, generate a first control signal for the switch to couple the transceiver to the first antenna for transmission of the first data frame by the transceiver via the first antenna;
• determine whether the transceiver has received within a pre-determined time interval after the transmission of the first data frame a second data frame containing an acknowledgement message confirming successful receipt of the first data frame by another device;
• and
• if the transceiver has not received within the pre-determined time interval after the transmission of the first data frame the second data frame, then generate a second control signal for the switch to couple the transceiver to the second antenna for re-transmission of the first data frame by the transceiver via the second antenna.
