Final Report
Chapter 9 Environmental and Social Considerations
case-by-case basis in accordance with the applicable standards of MPT, taking into account the node
distribution and condition of existing MPT facilities as well as road traffic conditions and traffic
volumes. The wireless system can be considered an alternative means, but its transmission capacity
is too low to cover the high transmission volumes within a large city or between cities.
A comparison of access links is shown in Table 9.3-2.

The access links for this project are specified under LTE and employ the point-to-multipoint radio
system, as shown in Table 9.3-2. Thus in this project there are no problems to be considered in terms
of the environmental aspect.
