Businesses use Radio Frequency Identification (RFID) systems to automate inventory and supply chain tracking, which reduces manual labor and errors.
Radio frequency is often likened to "invisible real estate." Just as land in a bustling city is more valuable than land in a remote desert, certain frequency bands—particularly those between 3Hz and 300GHz—are highly coveted because of their ability to carry large amounts of data over long distances or through solid obstacles. Organizations buy frequencies to:
In most countries, the government acts as the landlord of the spectrum. Agencies like the Federal Communications Commission (FCC) in the United States manage the sale of frequencies through competitive auctions. These auctions can generate billions of dollars for national treasuries, as companies bid for exclusive rights to certain "lanes" in the airwaves.
