Spektrum is a brand of radio control systems designed for use with hobby

radio-controlled cars Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely control a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small ...

. The R/C hobby in the United States, Japan, and Europe typically used to employ FM radio control in HF and VHF bands such as 27 MHz, 35 MHz, 49 MHz, and 72 MHz. Most manufacturers of radio gear (all non-toy manufacturers) now use the 2.4 GHz band for their transmitters and receivers. Spektrum systems are distinguished in that they use

. Spektrum refers to their technology as "Digital Spectrum Modulation." Each transmitter has a globally unique identifier (GUID), to which receivers can be bound, ensuring that no transmitter will interfere with other nearby Spektrum DSMx systems. The Spektrum system is also one of the manufacturers which offers "Model Match" in which the receiver in a particular model can be bound to one and only one transmitter model definition. This prevents a user from flying their RC helicopter while the transmitter is still programmed for their RC airplane. Spektrum is the original application of 2.4 GHz spread spectrum radio systems to radio control models. It was originally developed by Paul Beard. Spektrum broke the run of twelve consecutive Readers' Choice Award by

''Bind-N-Fly'' is a model that is ready to fly or drive once bound to an existing compatible transmitter. Spektrum was instrumental in bringing this term and concept into mainstream RC model vocabulary.
