Personal communicators have been in use since the early days of space exploration. There have been two different main versions of the personal communicators the handheld communicator and the wearable communicator.

The handheld communicators were obviously the first style of communicator used by Star Fleet. The communicator takes the form of a small box, sized to fit comfortably within the standard humanoid hand, with an antenna that is flipped up prior to use. This same antenna acts as a protective cover for the communicators control surfaces and speaker/mic assembly when in the closed position. The earliest version of this style of communicator was in use in the 2150 by the Star Fleet of the United Earth prior to the formation of the Federation of Planets and the founding of the Star Fleet of the UFP.

Wearable communicators have taken two different style. The first type of wearable communicators that were introduced into the fleet inventory was a wrist mounted that was issued in the 2270s. While this type of communicator remained in the fleet inventory until the 2290s the handheld communicator remained the preferred unit of use during away team operations due to the larger power cells in the handheld units allowed for longer use of the unit in the field.

It was not until the 2340s that the first version of the combadge style of personal communicators were added to the fleet inventory. Changes in the uniform guidelines that required the use of the combadge instead of the fleet insignia pin finally led to the combadge becoming the primary personal communicator.


Handheld Communicator Physical Arrangement:

Outer Casing:

The Outer Casing is formed from a sheet of monotanium/titanium alloy that is pressure formed into the required shape. The casing has a protective coating that has been electron bonded to the outer surface of the casing.

Subspace Transceiver Assembly:

The Subspace Transceiver Assembly (STA) incorporates and analog to digital voice encoder and lower power subspace field emitter. Voice inputs are received by a mono-film pick up diffusion bonded to the inner casing and routed to the STA.

For security reasons the STA sends out a low powered pulse that can be read by a ship's on board sensors allowing any crew member to be located on board a ship or station. During away team operations this pulse is emitted at a slightly higher power level so that transporter lock can be maintained for each member of the away team.


Encryption Circuit Assembly:

Prior to transmission the signal is routed to the encryption circuit assembly where it is converted by a series of encryption algorithms. These algorithms are changed on a random schedule by Star Fleet Command. To ensure ongoing security of transmissions during away team operations the algorithms can be changed at the direction of the Officer in command of the mission. This change affects only communications between the away team and the orbiting ship.

Power Cell:

The power cell used in the hand held communicator is a sarium crystal rated for 1 week of use under normal operational parameters. When the power cell reaches five percent energy level a low power indicator light will flash red at two percent the indicator will remain lit until the power cell has been swapped out.


Control Surface:

The control surface of the hand held communicator is covered by the flip up antenna when not in use. The surface itself houses the speaker/microphone assembly. The control surface also includes a channel sector, transporter lock conformation light, low power indicator light, volume and gain control buttons.

Commbadge Physical Arrangement:

Outer Casing:

The outer casing is micormilled duranium over layered with gold ans silver alloys in a diffusion bonding process. The gold and silver have no operational function and only serves to add to the aesthetic design of the comm badge.

Subspace Transceiver Assembly:

The Subspace Transceiver Assembly (STA) incorporates and analog to digital voice encoder and lower power subspace field emitter. Voice inputs are received by a mono-film pick up diffusion bonded to the inner casing and routed to the STA. While the standard STA possesses input channels for other data that are not used during the normal operations of the comm badge.

For security reasons the STA sends out a low powered pulse that can bee read by a ships on board sensors allowing any crew member to be located on board a ship or station. During away team operations this pulse is emitted at a slightly higher power level so that transporter lock can be maintained for each member of the away team.

Encryption Circuit Assembly:

Prior to transmission the voice signal pulses routed to the encryption circuit assembly where the are converted by a series of encryption algorithms. These are changed on a random schedule by Star Fleet Command of galaxy wide subspace during local away missions.

Power Cell:

The power cell used in the comm badge is a sarium kerllide crystal rated for two weeks in normal use. When close to depletion the crystal will produce a faintly audible oscillation to warn the user of the lower power levels. The power cell can be recharge via induction loop charging.

Dermal Sensor Controller:

The Dermal Sensor Controller (DSC) allows the comm badge to be personalized to the user it is issued to. A persons bio-electrical field and temperature profiles are used to keep an unauthorized person to access the communications systems via the combadge. The Dermal Sensor also detects the users fingers upon the outer casing. Tapping the combadge causes the DSC to send a power up command to the STA preserving the internal power supply.
