Abstract
This invention relates to data transmission in a microwave link system particularly through point-to-multipoint connections. The arrangement according to the invention utilizes both frequency and time division duplex arrangement to simplify substation structures. In accordance with the invention a substation transmits at different times than it receives, and uses different frequencies for the transmission and reception. The central station, in turn, includes a duplexer unit, whereby it can both transmit and receive simultaneously when the transmission and reception frequencies are sufficiently apart. Such an arrangement achieves advantages of the time division duplex arrangement, such as e.g. an inexpensive substation structure, without the drawbacks related to the time division duplex arrangement.
