Og 103 test and analysis of gsm electromagnetic background issue1.0Ketut Widya
In the GSM system, to extend the capacity, perform frequency reuse. If the frequency reuse is more aggressive, the network capacity becomes more large. If the reuse distance is shorter, the interference becomes stronger.
The interference has obvious impacts on call quality, call drop rate, handover, and congestion. If there is a strong interference in the band, clear frequency or apply for new frequency.
Feature adaptive configuration of traffic channel power offset for hsupa perf...Ketut Widya
User are served in HSPA service rather than PS R99 service. PS R99 DL and UL payload reduced 7.1% and 11.5% respectively but the HSDPA and HSUPA payload increased 14.6% and 16.9% respectively.
Mobile broadband services are undergoing a period of dramatic growth causing a tremendous increase in data traffic. This rising tide of traffic is being driven by the growing number of mobile subscribers, particularly smartphone users, who are connecting to faster networks and consuming bandwidth-hungry video content.
Adaptive configuration of traffic channel power offset for hsupaKetut Widya
The offset of E-DPDCH power relative to DPCCH RX power is one of the major factors that determine the DPCCH RX power. A UE in low-rate little retransmission state requires less DPCCH RX power than it does in high-rate little retransmission state.

Six in ten people in Asia Pacific subscribed
to mobile services in 2015
At the end of 2015, 62% of the population in Asia
Pacific (2.5 billion individuals) subscribed to mobile
services. The region’s four dominant markets
– China, India, Indonesia and Japan – together
accounted for more than three-quarters of the
region’s total subscriber base. Growth rates in the
region are set to remain above the global average,
with Asia Pacific adding more than 600 million new
subscribers by 2020. The focus of growth will shift
to South and South-East Asia; India alone is set to
add just under 250 million new subscribers by the
end of the decade.
Og 102 site survey and layout of bts issue1.5Ketut Widya
The survey and layout of BTS is the basis of construction for radio mobile network. It has the following functions:
Showing the system design of the network planning
Determining the structure of future network
Determining the quality of network operation
Thus, the proper survey and layout of BTS can ensure the installation, maintenance, and network planning
