All About Transmission/Microwave in Telecommunication
-> What Is the Transmission in Telecommunication field?Transmission is one of the system in Telecommunication that have function to connect two Site/BTS (Base transceiver Station) until to BSC (Base Station Controller) using frequency for medium.
In terms of transmission there is HOP. Hop consists of two site/BTS/Tower and usually called the near end and far end. Near end is a Site/BTS where we are, while the far end is a Site/BTS opponent
-> Transmission Component/Element.
Below is the component/Element in transmission :
Outdoor Unit usually abbreviated with ODU and indoor unit with IDU.
- Outdoor Unit: "Sets the radio communication frequency and performances".
Antenna :
RAU/ ODU/Radio:
Medium Capacity: Frequencies between 7 and 38 GHz with C-QPSK and 16QAM
High Capacity: Frequencies between 7 and 38 GHz with 16 QAM and 128 QAM
BAS: Only RAU2. Frequencies are 24, 26, 28 and 31 GHz using C-QPSK
In Transmission RAU/ODU or Radio have sub band pair High and Low like this.
- Radio Cable: "Carries modulated IF, supervision channels and DC power to the radio unit".
- Indoor Unit: MMU/Modem Unit, SMU, AMM, SAU, ETU and etc.
- Sets traffic capacity.
- Traffic and supervision channels termination.
