Microwaves are short-wavelength, high-frequency signals that occupy the electromagnetic spectrum 1,000 MHz (1 GHz) to 1,000 GHz (1 terahertz). This is just above the radio frequency range and just below the infrared range. The entire range is huge, but much of it is not used for data communications, especially at the high-end due to water absorption. See "Electromagnetic Spectrum."

This topic continues in "The Encyclopedia of Networking and Telecommunications" with a discussion of the following:

• Facts and figures about microwave systems
• Where microwave systems are useful
• Microwave system topologies
• MMDS and LMDS systems
• Multipath problems
• OFDM (orthogonal frequency division multiplexing)
