ANALIS PREDIKSI PENERIMAAN LEVEL SINYAL PADA DAERAH SUB URBAN TERHADAP UNJUK KERJA JARINGAN GSM
Abstract: Sub-urban area is a
suburban area (rural) with some of the barriers of trees, houses and buildings
that are not too high under 5 level. Some of the causes of interruption of the
call is limited channel reception level talks and the problem of RF signals
(radio frequency) where the quality of the signal level is strongly influenced
by local conditions damping propagation. The study was conducted in village
siduk, districtsnanga tayap, north kayong district, Problems GSM network
performance can be seen from the monitoring of traffic through NetAct software
by using parameter-parameter above as: SDCCH Blocking, SDCCH Drop, Loss RF SDCCH,
TCH Blocking, TCH Drop, and TCH RF Loss. Then do the calculation Prediction
Reception signal level using Okomura-Hatta. Manual calculation results in BTS
North Kayong siduk shows that the BTS antenna sector 1 with a power 27 W is
obtained within a range of 3.2 km with a reception signal level -80 dBm, while
the range desired by PT. Telkomsel is 3.5 Km, then power must be increased to
34.62 W. In sector 2, the transmit power of 27 W, within a range of 3.2 km,
with the reception signal level -80 dBm, the desired range of 3.8 Km, power
must be increased to 35.80 W. in the third sector, the transmit power of 26 W,
within a range of 3.1 km, with the reception signal level -80 dBm, the desired
range 3.5 Km, power should rise to 34.26 W. from the results of calculations
can be concluded that the performance of the BTS antennas siduk north Kayong
less than the maximum because of the decreasing transmission power due to the
loss of damping propagation in sub urban Reviewed sector antenna 1 is (2 dBm),
sector 2 is (3 dBm), sector 3 is (3 dBm). But in general is still quite good.
