Abstract

In doing microwave transmission interference and attenuation  effects , not so much propagation Line Of  Sight. Therefore it takes a computation and checking of a transmission network  that values ​​of interference does not greatly effect the availability value is supposed to be, there are several ways to avoid or even eliminate interference case is to replace the sub-band and change the polarization of the antenna system microwae. On the transmission network owned by Axiata PT.XL Banten there is a case of interference, namely the link Panimbang Hop-Labuan-Cigeulis due to using the same frequency and the same sub-band. RF Scanning seen from the results that the link is indeed indicated interference. Therefore, by using software pathloss 5.0 will be able to do an analysis of a link or network terinterferensi. so as to reduce and resolve a case interference occurs, and the value of a link availability can be well worth it. Optimization is done there will be a change of the ODU or replace the antenna polarization between vertical or horizontal. Optimization to do is replacing frequency channel that was using 1h (high) - 1l (low) the frequency is 7747.70 MHz-8059, 02 MHz, to frequency channel 3h (high) - 3l (low) the frequency is 7807.00 MHz-8118.32 MH. By doing this method interference value will be lost. Then after the optimization of the value of availability to 99.99993%.
