Early Application Of MMDS

- Mar 29, 2019-

The MMDS was originally used to transmit unidirectional television and webcasts. In 1970, the FCC divided 200 MHz at 2.5 GHz for wireless telecom operators, with a total of 31 channels with a bandwidth of 6 MHz per channel. Although the technology of MMDS has been continuously innovated, the market situation at that time was not mature enough and it did not receive enough attention. In September 1998, the FCC approved operators to use two-way data service transmission, allowing for more flexible use of the MMDS band. At the same time, the digital development of MMDS also makes it more competitive. Recently, the development of high-speed data access has promoted the development of MMDS.
