Network Design & Optimization ( NDO ) :
Site Surveys and Network Engineering Services
Radio Network Planning and Design
RF Network Audit
Drive Test Measurement & Analysis
Radio Network Optimization
Frequency Planning & Interference Analysis

RADIO NETWORK PLANNING & DESIGN

ENS takes turnkey Radio network Planning and design project or provide assistance to key areas of design. This broad field of designing a radio network for new town or enhancing the network in existing towns is classified under following steps and ENS provide consultancy service for all this.
Initial network design cell plan
Traffic probability and TRX/Capacity plan
Coverage in building and outdoors as required by the client
Rollout phase split and costing per phase
Subscriber projection and growth plan (using our specialized tool)
Frequency plan
Antenna type, TMA type, Repeater type, In building solution planning etc.
CW drive test and propagation modeling etc.
Candidate site surveys
Telecommunications Infrastructure work

RADIO NETWORK OPTIMIZATION


ENS provides consultancy on Network optimization where in we study the network architecture, check the BSS Statistics, Cell database set parameters, Dual band/triple band implementation methodology, congestion relief criterions, coverage and interference analysis, Drive test measurements, customer complaints and other problems faced in the network.
Many networks have their own benchmarks for drop call rate, call success rate etc. we with our expert skills and tools try to achieve the highest possible set benchmarks. And till date we have proven our mettle in all the network optimization jobs taken so far.

RF NETWORK AUDIT


ENS provides network audit services to its clients, which are telecom service providers or telecom vendors to have a complete know how of the implemented systems in the field. This could be site audit, where checks could be made on the antenna height, antenna type, azimuths, tilt, transmit frequency etc. which broadly fall under the hardware network audit. Under the software / Radio quality network Audit, we take tasks like drive test to identify black spots in coverage, quality etc. Frequency plan analysis where we check the carrier to interference ratio and the critical areas/regions with high interference resulting in bad voice quality.

FREQUENCY PLANNING & INTERFERENCE ANALYSIS

ENS specializes in preparing a new frequency plan for the network or plan for upgrade. We have stringent measures to achieve 98% of area with C/I > 15dB. This on its own is a highest benchmark possible to have the cleanest possible frequency plan for the network and we strive to achieve this.
We also plan for different types of frequency. Our performance in this arena is unique and our customer gains with interference reduction in the network quality and hence customer satisfaction and customer retainability.

DRIVE TEST MEASUREMENT & ANALYSIS


This could be clubbed with the network optimization project where drive test optimization is a part but this can also be taken as a different project altogether where we conduct multiple network drive test and provide measurement and analysis of our customer's network compared to the competitor's network and find out advantages, strong points, black spots etc. in all the networks. A thematic plot and the statistics generated from drive test are analyzed. This gives an insight into the areas of improvement needed in client's network compared to competitor and where are the locations where roaming coverage can be enhanced etc. All these data are very important for the service provider to know the reality of the network performance on ground.

SITE SURVEYS AND NETWORK ENGINEERING SERVICES

ENS is reckoned amongst the renowned service providers in Indonesia. We offer Site Survey & Acquisition, R.F. Survey and LOS Survey to our clients as per their needs. With the support of our experts’ team, we are able to offer effective services within the promised time frame to our clients.
We undertake site survey projects where the Radio Site survey engineer checks all the relevant points while doing the site survey so that the best site candidates are chosen. This results in good network design and coverage and quality as expected by the network planner. This is important as the network planner by using the planning tool could not judge the height of building/obstruction and local minor details. We have our own tools like GPS, binocular, magnetic compass and maps to provide a turnkey site survey project.
We specialize in capacity site survey for dense urban, coverage site survey for suburban and rural areas as well as in building site survey and micro cell site surveys.

NETWORK ROLL-OUT ( NRO )

Installation wireless telecommunication and microwave, such as Antenna and Radio System.

Maintenance service for wireless and microwave.

Evantama has the ability to upgrade to multiple projects, mainly due to its strong project management and implementation capabilities. evantama will always closely monitor the work process in the field and reduce human error which cuts time and effort to determine low cost project options. Fewer errors mean less site visits and we ensure the benchmark one-time installs. This allows lower labor costs for network deployments and reduces the time and cost of changing processes.

NETWORK ROLL OUT (RBS AND MINILINK)

Our range of Telecom Equipment Installation and Commissioning services is rendered on a timely basis and is very cost effective in nature. We offer BTS Installation & Commissioning and MW Installation & Commissioning on turnkey basis for telecom networks. Our installation team has experience of handling various telecom equipment and tools which are sourced from reputed companies like Ericsson, Nokia Siemens, Huawei, ZTE, Alcatel-Lucent, Nortel, Motorola, ECI, Ceragon and NEC.
Wireless cellular communication is witnessing a rapid growth in markets, technology, and range of services. A major current thrust for cellular communication systems is improved economics through enhanced coverage early in the life cycle of a network and high spectrum efficiency later in the life cycle. An attractive approach for economical, spectrally efficient and high quality digital cellular and personal communication services is the use of GSM and other wireless communication. These wireless communication systems communicate through cable or air link with one place to another place. In this work an iterative technique has been presented to explain the sequential communication of signal transmission for long and short distance radio communication through microwave link. The obtained process for GSM communication has been maintained fixed (NSS) and non-fixed side (BSS). Both sites are communicating through microwave link. This report presents the whole connection process of two sites (BTS to BSC and MSC and to achieve this, the following jobs are performed: installation & commissioning. The maturity of radio frequency (RF) technology has permitted the use of microwave links as the major trunk channel for long and short distance communication.

INSTALLATION & COMMISIONING

Our organization is also offering cost effective Engineering and Commissioning services for telecom equipment and instruments. We have a team of well – qualified and experienced engineers and technicians, which has sound knowledge and technical expertise. These professionals are capable of installing and commissioning a wide range of telecom equipment, as per the need and demand of the clients.

TELECOM IN-BUILDING SOLUTIONS INFRASTRUCTURE

To ensure adequate strength and quality of wireless signals, it is essential to have a dedicated in-building solution. Similarly for other wireless services such as Wi-Fi, Wi-Max, Wireless Broadband, etc. such a dedicated Infrastructure is the need of the hour. And with 3G on the horizon, the need for a dedicated communication infrastructure is now more than ever. Additionally, such infrastructure should be capable of supporting multiple operators.
