Deployment of mobile operator networks

This line of activity covers turnkey development of mobile operator sites, including:

• Facility search;
• Design;
• Site development;
• Installation of equipment;
• Facility legalization;
• Addition of a new standard.

Facility search:

For search of construction sites and conclusion of a lease agreement with the land or building owner, “searcher” managers are employed. Their duties include search of a site fit for construction, coordination of a preliminary project solution and conclusion of a lease agreement.

Design:

Design is performed by the RD Department in line with the Ukrainian regulatory system and the Customer’s requirements, under the supervision of the RD Department Head. Quality control and compliance of the design documents to the Ukrainian regulatory system and the Customer’s requirements are vested in the Chief Project Engineer.

Given the qualifications and present staff of the RD Department, we can  perform design work of any type and complexity in the field of radio communications. 

Dependent on the Customer’s requirements, the complete design includes the following sections of design documents: Memorandum, Technology concept, Architectural and construction concept, Power supply, VAC, EIA.

Memorandum – a memorandum is the part of the contractor’s design subject to approval. The memorandum includes:

• description of technical decisions accepted for the project;
• labor and fire safety sections;
• EIA section – calculation of environmental impact of radio frequency emission.

Technology concept – the section includes design drawings associated with performance of a set of operations of antenna-feeder device laying, as well as placement and connection of transceiver equipment.

Architectural and construction concept – the section includes design drawings associated with performance of a set of construction and assembly operations, as well as drawings of technically simple metal structures of antenna supports.

Metal structures – the section includes design drawings of technically complex structures of antenna supports, such as masts and towers.

Reinforced concrete structures – the section includes design drawings associated with performance of a set of operations at installation of basements and ferroconcrete structures of antenna supports.

Power supply – the section includes design drawings associated with performance of a set of electric installation works, electrical equipment, power supply, electric lighting, grounding and lightning protection of base stations.

VAC (ventilation and air conditioning) – the section includes calculations and design drawings associated with performance of a set of operations at installation and connection of ventilation and air conditioning systems at base stations. 

A sample drawing is presented here.

Development:

Under the supervision of the Project Manager and the Chief Project Engineer, on the basis of the produced design documentation and the work schedule, the civil-engineering design is performed. The construction technology and process depend of the site complexity. ESU performs those operations either on its own or employing contractors specializing in specific kinds of work.

Installation of equipment:

Equipment is installed by specialized company engineers. Be it a new facility or modernization of an existing one alike, installation of a base station and power supply systems proper is preceded by elevated jobs. That stage involves power, coaxial and optical cable laying, antenna and radio frequency module assembling. Such works are performed by steeplejacks appropriately certified and qualified to do so.

After that, connection and integration of the base station and power supply systems rests with the installer. Qualification of our personnel is sufficient for installation and integration of Nokia, Huawei and Ericsson base stations.

Facility legalization:

The last stage of base station construction or modernization involves its legalization, meaning receipt of a package of licensing documents for legitimate operation of communication facilities, including from the Ministry for Emergencies, as well as the sanitary-epidemiological, labor and fire safety certificates.
