Abstract
A radio system comprises a radio (1) having a transmit mode activated by a press to talk (PTT) switch (16) mounted on a universal communication interface (12) for mounting on a radio interface (6) associated with the radio (1). The radio interface (6) may or may not form part of the radio (1) and a plurality of radio interfaces may be provided for different applications, such that a standard universal communication interface (12) can be used with different types of equipment.
Claims29
A radio system (1, 12, 19, 33) comprising a radio (1) having a transmit mode and a press to talk (PTT) switch (16) to set the radio to a transmit mode, characterised in that the system further comprises a radio interface (6, 19) associated with the radio and a universal communication interface (UCI) (12) in which the PTT (16) switch is located, the radio interface (6, 19) arranged to releasably mount said UCI (12) and provide communication between the UCI (12) and radio (1) when mounted thereon.
A system as claimed in any preceding claim wherein the radio interface (6) is on the housing of the radio (1).
A system as claimed in any preceding claim wherein the radio (1) is a personal role radio arranged to be worn by the operator.
A system as claimed in any preceding claim wherein the UCI (12) is arranged to be connected to said radio (1) by means of the radio interface (6, 19) and to be connected to a second radio by means of a wire or optical link (21).
A system as claimed in any preceding claim wherein the UCI (12) has two PTT switches (16, 17) mounted thereon, one associated with a first radio (1) and the second associated with a separate radio network.
A system as claimed in any preceding claim wherein the UCI (12) comprises a connection (15) for an operator headset.
A system as claimed in any preceding claim further comprising a wired remote PTT module having a PTT switch (24, 25) which module is small relative to the UCI (12), the UCI having a connection for the wire (22) of the remote PTT switch so that the function of the PTT switch (16) of the UCI can be operated remotely of the UCI (12).
A system as claimed in any preceding claim further comprising a cordless remote PTT module (33) comprising a PTT switch (34), the remote module (33) comprising a short range, relative to the radio, transmitter (38), the UCI (12) comprising a receiver (42) for receiving signals from the remote module (33) to remotely activate the function of the PTT switch (16) of the UCI (12).
A Universal communications interface (UCI) (12) for a system as claimed in any preceding claim.
A personal role radio (1) comprising a radio interface (6) for a system of any preceding claim.
A radio system substantially as hereinbefore described and/or as illustrated in one or more of the accompanying figures.
