RAN Installation
A radio access network (RAN) is a major component of a wireless telecommunications system that connects individual devices to other parts of a network through a radio link. The RAN links user equipment, such as a cellphone, computer or any remotely controlled machine, over a fiber or wireless backhaul connection. That link goes to the core network, which manages subscriber information, location and more.

RF Optimization
Radio Frequency Optimization is a process through which different soft (Cell Reselect Offset, BTS power) and hard (e.g. Electrical Tilt, Mechanical Tilt, Azimuth etc.) parameters of the Base transceiver stations are changed in order to improve the coverage area and improve quality of signal.
- Roll Out Optimization (New Sites Optimization)
- Strategic Optimization (Global RF Parameter Modification Optimization)
- Network Performance Improvement (Network Quality, Capacity, Coverage, Data Optimization)
- Network Benchmarking (Mobile network benchmarking campaigns gather information to characterize QoS and QoE)
- Drive Test & Drive Less Optimization (Drive Test Optimization by using tools)
- Network Automation (SON - Self Organizing Network - makes planning, configuration, optimization simpler and faster)
- MS RF Optimization (Telecom managed services to help plan strategy)
- Core Optimization (UMTS Ran, UMTS Core, VoLTE, LTE Ran Optimization)

Network Performance Improvement & Benchmarking
To keep survive in network competition, despite of Network Performance Monitoring, GSI Solution provides Network Performance Improvement services. This services includes: 1. Network capacity improvement 2. Network payload improvement 3. Network quality improvement 4. Network coverage improvement
Network Benchmarking Benchmarking tests against the competition are an effective way of measuring the marginal improvements that are necessary to trigger focused investments. It is also an effective way of getting to know the competition and to gather valuable information as a source for focused promotional campaigns.

Drivetest & Driveless Optimization
This service is to complement optimization consultants in collecting all relevant and necessary information from the network by performing field measurement (drivetesting and/or walktesting). Activities included are: drivetest route definition, drivetest route checking, drivetest data collection, drivetest data post processing, identification of problematic areas, adjustment of antenna tilting and orientation and parameters adjustment where applicable.

FTTH Installation
FTTH stands for Fiber to Home which refers to broadband internet connection technology that uses fiber optic cables to deliver internet directly to individual homes. This method involves laying fiber optic lines from the internet service provider (ISP) directly to the user residence allowing for high speed and stable internet connections. FTTH provides significant advantages over traditional copper or coaxial cables including faster data transmission rates and improved reliability.
Nowadays Fast internet Access could be done using Fiber Optic Network as the transmission medium. Based on this condition FTTH Project was initiated to expand Fiber Optic in Indonesia.
