ANALISIS JARAK ANTARA DUA KANAL YANG BERBEDA YANG SALING BERDEKATAN PADA SATU BTS BERSAMA
Abstract: The different
space of joint
BTS would potentially
create interference which could interfere the performance quality
of an operator. Isolation denoted a value from each antenna which had common
value of 30 dB. This minimum spacing calculation was used according to space
isolation calculation. In case of frequency of 1710 up to 2170 Mhz, it was
obtained that the minimum vertical spacing was 0.15 up to 0.19 meter, for
frequency of 1710 up to 2170 Mhz, it was obtained that the minimum horizontal
spacing was 0.63 up to 0.82 meter, for slant spacing obtained with isolation
value was 71.436 dB. Spacing installation at BTS PAL 5 Jln Husin
Hamsah, RT/RW 005/001,
Kelurahan Paal Lima,
Kecamatan Pontianak Barat was
4.5 meter for
vertical spacing, 2
meter for horizontal spacing, and 71.436 dB which was
more than 30 dB for slant isolation. Thus, the result obtained in the field
showed antenna spacing at BTS PAL 5 Barat had met the standard for antenna
isolation. Antenna with isolation value of <30 dB had to be adjusted toward
installed antenna; extent spacing between one antenna to the others; adjust tilt
of antenna in order to increase
isolation value of antenna; adjust
azimuth angle by getting it away from antenna that had been interfered so that
the isolation value of the antenna met the standard. The receiving level of MS
also had to be taken into account to measure the power of receiving signal of
each MS from installed antenna, with Walfish-Ikegami method, it was obtained that
the value of receiving power decreased upon spacing of 1km from antenna, so
that there should be certain adjustments toward the height of the antenna.
