During 1990s microwave radio links begun widely to be used for urban links in cellular network. Requirements regarding link distance changed to shorter hops (less than 10 km (6.2 mi), typically 3 to 5 km (1.9 to 3.1 mi)), and frequency increased to bands between 11 and 43 GHz and more recently, up to 86 GHz (E-band).
AT&T continued using its microwave network for telephone service through this period, but Sprint's 1980s all-fiber, all-digital network forced the company to switch to digital as well, using new fiber rather than updating the microwave system. By the late 1990s, most of the microwave network had been turned off.
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy (heat) in a process known as dielectric heating .
In 1947, just a year after Spencer’s snack food serendipity, the first commercial microwave oven hit the market. Called the “Radarange,” it weighed nearly 750 pounds and cost more than ...

Microwave is a form of electromagnetic radiation with wavelengths shorter than other radio waves but longer than infrared waves. Its wavelength ranges from about one meter to one millimeter, corresponding to frequencies between 300 MHz and 300 GHz, broadly construed.
