WAY HOW WE WORK - PLANING T- DVB  or T- DAB  NETWORK - PROJECT PLANING 

SARTELCOM - T-DVB TURNKEY SOLUTIONS

Digital terrestrial broadcasting services, both for television and radio, are proving a big success in Europe, as improved service quality, low set-up costs and increased content offered by the broadcasters attracts more viewers and listeners to these new platforms.

As new established company, SARTELCOM offering Turnkey Solutions for Terrestrial  Digital TV Program Transmission and receiving with short name T- DVB and Terrestrial  Digital Radio Program Transmission and receiving with short name T- DAB and our task is to help TV Networks or TV stations and Radio stations to build their new Terrestrial Digital System for Broadcast as T-DVB or T-DAB.

For planing T- DVB and T- DAB we have determine following steps before we start doing any projects for you and this is THE AVAILABILITY OF FINANCING FOR THE PROJECT, and after that we start work for you:

  • project planing phase
  • project realization phase
  • equipment delivery phase
  • equipment installation phase
  • training and education for new staff
  • equipment commissioning phase
  • putting new network in service
  • equipment maintenance phase.

PLANING T- DVB or T- DAB NETWORK

Digital broadcasting services T-DVB-T and T-DAB require higher prediction accuracy than traditional analogue networks, because digital services are planned with tighter margins on the signal strength and interference.

We will here describes steps we do to get prediction models that offer higher accuracy and which can be used to optimize digital broadcasting networks, you asking to be build from SARTELCOM.


NETWORK PLANING SOFTWARE

We use specific Network Planning Software where we analyze all the parameters for the future use. This parameters are: field strength coverage from particular site, for this we need latitude and longitude coordinates and altitude above see level. Digital broadcasting services T-DVB-T and T-DAB require higher prediction accuracy than traditional analogue networks, because digital services are planned with tighter margins on the signal strength and interference.

On customer request we do a 3D maps which can show showing coverage area covered from their TX point and its configuration as is TX power from the transmitter, antenna system, tower height,etc.

Propagation chart examples.

In the same way we suggest to the customer the better configuration if needed to cover an indicated area from a given location. This tasks we can do for T-DVB, T-DAB and for Analog or Digital Microwave Links. If, needed we suggest to our customer configuration change, needed to cover an indicated area from a given location.


Parameters to be considered for any future T- DVB or T- DAB TX site:

  • TX location are based on latitude and longitude
  • TX site altitude location ground
  • TX power
  • TX Antenna Gain
  • TX RF transmission losses
  • Transmitting frequency
  • Transmitting Vertical Pattern
  • Transmitting Horizontal Pattern

Propagation & defraction:

  • Fresnel zone
  • Deygout diffraction correction to account for propagation over geographic features such as hills.
  • Free Space zone
  • Recommendations ITU R370-7

Network Analysis:

  • Sight of Line
  • Intermodulation
  • Propagation
  • Composite Coverage
  • Field Simulcast

When all above is accepted in writing form and paid from our customer, we proceed with another phase.


PROJECT REALIZATION - PROJECT STARTING

SELECTING T- DVB or T- DAB EQUIPMENT
Another phase is selecting T-DVB or T-DAB equipment from our suppliers or our system integrators and partners per our customers wishes and customer financial strength or available funds for the project. We supply all the products and equipment for T-DVB and T-DAB inside your Shelters or Container or regular building space. We do calculation for your Shelters or Container type space where equipment will be installed per our specifications.We do calculation for your air condition needs for your Shelters or Container type space per our calculations.

EQUIPMENT PURCHASE
Equipment is purchased and paid  from our customer. All the equipment is assembled and tested in the manufacturer factory. When all this job is done and controlled by SARTELCOM supervisor we go to pack all equipment and send to destination.

EQUIPMENT DELIVERY
At the end we do the shipment of all the goods. Using a reliable shipping company or agent we can provide a Transportation Services all over the world.

EQUIPMENT INSTALLATION
After the goods arrived our SARTELCOM installation team will arrive to perform all the installation and system start-up.SARTELCOM technical team are experienced technicians, engineers, tower-erection specialists, and highly specialized workers will manage all the parts of the installation. We always leads this kind of project with SARTELCOM supervisor.

TRAINING AND EDUCATION FOR NEW STAFF
We have unique policy to use your OWN technical staff or YOUR NEW OWN hired staff to work with SARTELCOM technical team, who are experienced technicians, engineers, tower-erection specialists, and highly specialized workers IN INSTALLATION PROCESS. Before installation all the future staff will be trained in manufacturer premises or as per customer request. We use your staff to LEARN AND EDUCATE THEM SELF IN TIME WHEN WE DOING INSTALLATION, TOGETHER. We always establish personal relationship with your staff in time of installation, because they learn from SARTELCOM team, all the possible later problems which might appear and simply find the fault, because they do installation with SARTELCOM team.

EQUIPMENT COMMISSIONING PHASE
In this phase all equipment is accepted in writing form from the customer that is per their request and per requested specifications.

PUTTING NEW NETWORK IN SERVICE
In this phase all equipment is put in real service or in testing mode, to test all the system as a whole. In this phase customer can start to do own marketing and advertising new network via TV, Radio, newspaper, billboards and can show in real advantages of new T-DVB or T-DAB system.

END OF PROCESS
We hand over installed T-DVB or T-DAB network system to our customer to use.

EQUIPMENT MAINTENANCE PHASE
In order to get system work with minor technical fault we prefer proper preventive maintenance.
