Facebook hits 20Gbps in tests for internet drone data transmission


Facebook has succeeded in transmitting data at almost 20Gbps between two towers in Southern California in tests of a technology key to its plans to deliver internet service to rural areas using drones.

The tests were conducted earlier this year and made use of frequencies in the so-called E-band, a group of millimeter wave frequencies between 60 and 90GHz.

Such signals are capable of high-bandwidth data transmission but are susceptible to attenuation from distance, weather, and obstacles, so they are typically used for short-range, point-to-point transmissions.

Facebook used a 60-centimeter dish to send data over a 13-kilometer link between Malibu and Woodland Hills.
