and DTH Center, Pathum Thani. This will help the Company assess, control, and prevent potential impacts within
the satellite station and surrounding communities. It is one of the missions regarding responsibilities to the
environment, society, and employees working at the satellite service station of Thaicom.

In 2022, the Company measured the level of electromagnetic radiation at Thaicom Teleport and DTH Center,
Pathum Thani. The data was used to compare with the electromagnetic field strength limit for people receiving
generalized electromagnetic waves in order to consider the amount of effect of electromagnetic waves on human
health as per the standard of the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Objectives:
1. To measure the strength of the electromagnetic field in the area of the Thaicom satellite station

2. To compare the measurement results of the electromagnetic field strength in the area of the Thaicom
satellite station with the ICNIRP standard for the safety of electromagnetic fields for humans in the
vicinity of the transmission antennas
3. To use the results of the measurement for designing the protection systems or correcting the effect of
electromagnetic fields on humans if the level of magnetic field strength exceeds the limit according to
the ICNIRP standards.

Summary of Electromagnetic Wave Measurement Performance
By measuring the level of electromagnetic waves in areas in and around the Thaicom Teleport and DTH Center
(Lad Lum Kaew), the measured values are calculated to compare with the limit value based on the ICNIRP standard
(i.e. less than 1). The results are plotted in the following graph.

The graph shows the measured results of all the 3 frequency bands, that is, C-Band, KU-Band, and KA-Band. The
sum of all values when compared with the limit value is still below 1 at all locations measured. Therefore, it can be
considered that the level of an electromagnetic signal is safe for workers in accordance with ICNIRP standards
within and around the station.
