Each antenna is individually-controlled and may embed radio transceiver components. The meter transceiver and the reading transceiver both send and receive radio signals. The fiber end is connected with the transceiver device called Small form-factor pluggable transceiver. An intra-section level portable VHF FM transceiver. The newest module standard is the enhanced small form-factor pluggable transceiver, generally called SFP+. A vehicle-mounted VHF FM transceiver built by Marconi Space and Defence Systems. An intra-platoon level backpack VHF FM transceiver. A forward air control UHF AM transceiver. Transmission is accomplished by controlling the driver enable pin of the transceiver. This is accomplished using a passive splitter prism inside each transceiver. Both devices are available with integrated transceiver options. NASA distinguishes between a "transceiver" and "transponder". Aviation communication was by morse code transceiver. These two are sometimes combined to form a two-way communication device known as a transceiver. The SCR-300 was an 18-tube battery operated radio transceiver.
