MMDS Broadband Transmitter
Multi-channel Microware Distribution System (MMDS) is also called wireless cable or open-to-air cable. Internationally, MMDS normally uses 2.1- 2.3GHz, 2.3-2.5GHz or 2.5-2.7GHz frequency spans, and the most commonly used span is 2.5-2.7GHz which also being used in China. MMDS is a mature and stable TV distribution and transmission system, which makes it an important way of transmitting TV programs to households and CATV head-ends.GOSPELL's MMDS broadband transmitter GT-5527 has stable performance, with complete range of functionalities and great variety, it can support single or multiple channel transmission, in modulation modes of CMMB, DVB-T/C/S, DTMB and many others, thus is able to suit most of the needs from both regional and overseas customers.
