Communication apparatus, a communication arrangement and a communication method
First Claim
1. A communication apparatus for push-to-talk communication over a professional mobile radio, the apparatus comprising:
- a control portion for controlling the push-to-talk communication, the control portion connectable to a microphone and to a loudspeaker and comprising a first optical transceiver portion configured toconvert an optical downlink signal into an electrical downlink audio signal for presentation to a user via said loudspeaker, andconvert an electrical uplink audio signal received from said microphone into an optical uplink signal for provision to an interface portion;
two or more separate interface portions, andtwo or more separate and dedicated bi-directional optical links for connecting the control portion to a respective one of the two or more interface portions,wherein each interface portion is connected to the control portion by a respective one of said two or more separate and dedicated bi-directional optical links, each interface portion connectable to a respective one of two or more radio portions by a respective electrical connection, which radio portion enables communication with one or more remote communication apparatuses via a respective wireless communication link over one or more communication channels, each interface portion comprising a respective second optical transceiver portion configured toconvert a downlink signal received from the respective radio portion as an electrical signal into said optical downlink signal for provision to the control portion, andconvert said optical uplink signal into an electrical uplink signal for provision to the respective radio portion.

11. A method for controlling push-to-talk communication over a professional mobile radio using a communication apparatus comprising a control portion for controlling the push-to-talk communication, which control portion is connectable to a microphone and to a loudspeaker and two or more separate interface portions, each interface portion being connected to the control portion by a respective one of two or more separate and dedicated bi-directional optical links, each interface portion connectable to a respective one of two or more radio portions by a respective electrical connection, which radio portion enables communication with one or more remote communication apparatuses via a respective wireless communication link over one or more communication channels, the method comprising:
-
providing an uplink signal over an optical link, comprising converting, in the control portion, an electrical uplink audio signal received from said microphone into an optical uplink signal for provision to an interface portion, providing said optical uplink signal over the respective optical link to an interface portion, and converting, in the interface portion, the optical uplink signal into an electrical uplink signal for provision to the respective radio portion, and providing a downlink signal over an optical link, comprising converting, in an interface portion, a downlink signal received from the respective radio portion as an electrical signal into an optical downlink signal for provision to the control portion, providing said optical downlink signal over the respective separate and dedicated bi-directional optical link to the control portion, and converting, in the control portion, said optical downlink signal into an electrical downlink audio signal for presentation to a user via said loudspeaker. - View Dependent Claims (12, 13, 14, 17)
