Degradasi Jaringan TD-LTE 2.300 – 2.400 MHz Akibat Interferens Alur-Waktu Silang
Abstract: Indonesia has set
the frequency band 2,300-2,400 MHz (3GPP band 40) as one of the frequency
allocations for the TD-LTE mobile network. Consequently, the implementation of
TD-LTE should pay attention to the phenomenon of Crossed Timeslot Interference
(CTI) which can occur as a result of the operators’ uplink-downlink
configurations. A work simulating the impact of CTI interference that occurs
between two network operators having an adjacent spectrum allocation is
developed. Network performance indicator is measured through the value of Bit
Error Rate (BER) and throughput value of Physical Downlink Shared Channel
(PDSCH). The results show that the CTI has caused a degeneration of BER leading
to a reduction of throughput value of PDSCH by 15.29%. This work is expected to
be a reference for Indonesian network operators to pay more attention to the
phenomenon of CTI which could potentially cause degradation of TD-LTE network
performance.
