Vietnamobile – an Ericsson’s customer, would like to widen 4G technology in Central and Southern of Vietnam. COMIT is the only partner who can provide full-life cycle RAN Optimization, was invited by Ericsson to support them in this project. The scope of work covered drive test, data collection, data analysis, change recommendations, change implementation, OSS KPIs optimization, hardware-faults fix, KPIs monitoring, license, feature, parameter sweeping, audit after optimization and reports. At the beginning of the project, most of KPIs (Key Performance Indicator) were negative.

Due to strict timeline, COMIT engineers had worked under high pressure continuously in 2 months without any days off, even weekend or holidays.

Results:

- KPIs were met.

- Successfully implemented 256 QAM DL / 64 QAM UL helping boost the speed of Vietnamobile network and improve customer experience.

- Balanced the load between U900-L900, which helped optimize the flow of data between the 3G-4G technologies, also helped customers stay on top of the speed of internet.

- Increased 350% of 4G traffic (3G remained stable).

- Detected 13 outside noise areas which affected Vietnamobile network quality.

Viettel - is recognized as one of the top telecom service providers in Vietnam and Southeast Asia and joins top 100 enterprises in the world. In Vietnam, their number of subscribers reached 60 million in 2017 (counting for 46.7% of total Vietnam telecom subscribers). With their huge data, and as the leading service provider in Vietnam, Viettel always leads the market with new technology application. In 2018, Viettel decided to apply artificial Intelligence in monitoring their big data, creating and running marketing campaigns.

COMIT and its partner - Flytxt (one of the fastest growing developers of software in the rapidly growing fields of artificial intelligence, analytics and marketing automation) was chosen to deploy this project with the solution: Neon DX. NEON-dX allows Viettel to gain an even deeper understanding of its customers with insights so that Viettel can send micro-segmented and personalized offers that reflect the customer’s contextual needs and interests in real-time. This ensures customers get the best service across all channels and help Viettel maintain a leading position when it comes to customer engagement.

The rapid development of the Myanmar telecom industry had brought many challenges to Myanmar’s telecom regulator. One of them was how to manage and plan Radio Frequency efficiently. And the deployment of a RF spectrum monitoring system was an answer.

COMIT (together with its local partner) and the solution from TCI (USA) – the advanced solution that has been provided to many countries from North America to Europe, and Asia, worked closely with Myanmar’s telecom regulator to understand deeply their needs and requirements in both technical and application aspects.

Due to COMIT’s successful deployment of a Spectrum Monitoring System in 2014, two years later, in 2016, Myanmar’s telecom regulator continued appointing COMIT together with its local partner to implement new Spectrum Monitoring System and Direction Finding up to 8 GHz. With extensive experience COMIT implemented a turnkey solution of a Monitoring Control Center and 11 sub-systems of fix and transportable monitoring stations. The new monitoring system covered all kinds of terrains from plains to mountains. The project was successfully completed and met the time requirement of customer.

In March, 2017, Movitel – the largest service provider in Mozambique had troubles monitoring 3 nodes OUT from a server of ONMSi system, and some of the other nodes were also unstable. Each node was responsible for tracking 24 cable lines which provide the transmission to the customers. As a reason for the incident, the quality of Movitel telecom network could be declined, and took time as well as many resources to overcome.

At that time, Movitel and COMIT did not remain any service level agreement. However, facing up with the emergency of customer, COMIT, with the spirit of “Devotion to customer”, immediately formed a support team to help Movitel solve the problem. With extensive experience in telecommunication testing and measurement, very soon, COMIT’s technical experts found the solution that examined, then re-enumerated the monitoring status of each node, and defined which error could be occurred. The Team worked hardly and continuously in three weeks notwithstanding time zone difference, poor connection, no days off, staying up late, waking up early…The problem of Movitel was solved quickly, all the nodes worked smoothly to track and ensure the transmission of the network.

Moreover, that was not even where the “Devotion to customer” spirit stopped. After helping the customer troubleshoot the emergency incident, COMIT provided free advanced training courses for Movitel engineers on issues when using the products and solutions.

"Devotion to customer" is one of the core values of COMIT since establishment, and despite any difficulties, customers can trust that COMIT will always be together to find solutions.

Dairyworks source high quality, bulk cheese and butter from local South Island suppliers and package it into consumer products for supermarkets, convenience stores and other retail outlets throughout New Zealand and Australia.

Dairyworks acquire the weight data for reports in real time from a numbers of checkweighers in throughout the factory. Some applications required local PLCs to know product weights for process indication and control. Dairyworks use the Modicon M340 PLC for automation and data control.

This unit is, a powerful and versatile PLC however did not have native support for the ASCII protocol over Ethernet TCP/IP.

Dairyworks solution was to use an eWON 500 to get weight data from all of the checkweighers over the Ethernet TCP/IP connection. We used the eWon script to control/report status of data connections, receive and reformat weight data, tag and store in eWON memory.

The PLC, using Modbus TCP, reads and writes to the eWON memory to get the data it needs and control and test data connections.

The solution is simple, rather inexpensive and has proved reliable. It allows data to be shared on PLCs and HMIs allowing the operators live access to meaningful graphically presented production data.
