Explore: Economic Aspects Of Radio Frequency Identification Systems

Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 Hertz (Hz) and 300 gigahertz (GHz)

at stations and onboard the locomotives; remaining are the radio-frequency identification (RFID) tags, that are placed between the running rails; and

broadcast TV system, so they are generally only used for MMDS and satellite television, which uses frequencies from 2 to 12 GHz. TV systems in most countries

television systems (or terrestrial television systems outside the US and Canada) are the encoding or formatting systems for the transmission and reception of terrestrial
