1. What is the primary field of business of Tunc Holding and its subsidiaries?

The subsidiaries of Tunc Holding are engaged primarily in providing products and services associated with the creation of turnkey GSM (Global System for Mobile Communication) networks. The spectrum ranges from the development and delivery of complete systems, including all required infrastructures, to service and maintenance. Tunc Holding companies provide support during all phases of in the construction and operation of complete networks and individual base stations.

2. What services are provided by the subsidiaries of Tunc Holding?

Working through its subsidiaries, Tunc Holding serves as an expert partner to organizations involved in the development and expansion of communications networks in countries of Gulf Region, Central Asia, Caucasus and Eastern Europe. The spectrum of services offered ranges from planning to realization to maintenance and repair of GSM technology networks.

3. What are the goals of Tunc Holding?

One of the declared goals of the company is to develop and strengthen business relations with European firms in the telecommunications and electrical power industries. The proceeds of the initial public offering will be used, among other things, to support further expansion, especially in the Gulf Region. In addition to expanding its already strong customer base in the GSM sector, Tunc Holding will also focus on raising its market share in the power supply sector as expansion progresses. Available capital will also be used to ensure continuous enhancement of corporate technical know-how. With this goal in mind, Tunc Holding AG plans to build a training and education centre for engineers and technicians in Turkey in cooperation with the highly renowned university in Ankara. The benefits of this institution will be not be restricted to Tunc Holding companies alone.

4. In which countries is Tunc Holding represented?

At present, Tunc Holding is represented by subsidiaries in seven countries: Azerbaijan, Georgia, Iran, Kazakhstan, Saudi Arabia, Turkey and the Ukraine.

Projects have also been successfully completed in Afghanistan, Algeria, Moldavia and Tunisia. Since January 2008 Tunc Holding AG is working on a GSM Projekt for Huawei Technologies Albania SH.P.K. in Albania.

5. What objectives does Tunc Holding pursue?

The objectives of Tunc Holding follow several different directions. The focus in the area of customer relations is on continuing to meet high standards in terms of customer satisfaction and service. In the field of technology, plans call for the establishment of a training and education centre for engineers and technicians in Turkey. Further expansion of activities into other business fields is also planned in the mid- and long term.

6. How can the corporate philosophy of Tunc Holding be defined?

The companies of Tunc Holding AG strive to realize technological innovations for their clients in the form of cost-effective solutions. They aim to ensure maximum efficiency through high-quality service. Customer needs and customer satisfaction are the yardsticks by which day-to-day work and all activities are measured. In order to achieve this, Tunc Holding pursues a policy devoted to continuous updating and improvement of the know-how as well as the technical and organization skills of employees and management.

7. What is GSM?

GSM stands for “Global System for Mobile Communication”. This technology provides the means for wireless communication and is now in widespread use in the field of mobile telephone communication.

8. How does GSM technology work?

Expressed in a nutshell, GSM works on the basis of electromagnetic waves that provide for the transfer of data between different stations.

9. What advances have been made in GSM technology?

GSM technology is an open standard that has already passed through many stages of development. Thus the GSM family now also includes GPRS (General Packet Radio Service), EDGE (Enhanced Data Rates for GSM Evolution) and the third generation of GSM Services (3GSM).

10. How is electromagnetic radiation generated?

In the interest of precision, it is appropriate to speak of electromagnetic waves. These waves consist of coupled electrical and magnetic fields. The fields are created when, for example, alternating current flows through an antenna. The antenna emits the electromagnetic radiation into its surroundings at the speed of light. Waves differ in terms of energy level, which is referred to as frequency. The category of electromagnetic waves includes radio waves, microwaves and the entire spectrum of light waves as well as x-rays and gamma radiation.

11. How dangerous is electromagnetic radiation?

The hazards posed by this radiation differ depending on the wave frequency. Alpha, beta, gamma rays and x-rays, for instance, can penetrate into human cells and alter genetic material. These rays are more highly charged with energy than radio waves and microwaves, which cannot cause cell changes. Previous studies have provided no definitive answer to the question of whether radio waves pose a danger to the human organism and, if so, what the nature of that danger might be.

12. What is Tunc Holding doing in response to potential hazards?

Tunc Holding places strong emphasis on keeping the level electromagnetic radiation as low as possible. As a testing lab, the Tunc Telekomünikasyon EM Field Measurement Center performs the required measurements and issues certificates documenting compliance with guidelines for implemented GSM systems. The base stations now in use in mobile telephone networks are low-power transmitters. The antennae of this transmission stations emit waves that are typically very narrow in the vertical plane and very broad in the horizontal. Due to this narrow vertical reach, the intensity of radiation directly beneath the antenna is very low, and the strength of the magnetic field decreases as one moves farther away from the antenna.

13. Where might I come in contact with electromagnetic radiation?

We are constantly surrounded by electromagnetic waves. Even the human body and the earth have their own electromagnetic fields. In today’s world, a substantial amount of radiation is emitted by the equipment and appliances we use every day. We are continuously exposed to electromagnetic radiation in the office (computers, printers, fax machines), at home (washing machines, microwaves ovens, electric razors) and while travelling (mobile telephones, radio masts).
