In recent years a substantial increase in the development of broadband wireless access technologies
for evolving wireless Internet services and improved cellular systems has been observed [1].
Because of them, it is widely foreseen that in the future an enormous rise in traffic will be experienced
for mobile and personal communications systems [2]. This is due to both an increased
number of users and introduction of new high bit rate data services. This trend is observed for
second-generation systems, and it will most certainly continue for third-generation systems.
The rise in traffic will put a demand on both manufacturers and operators to provide sufficient
capacity in the networks [3]. This becomes amajor challenging problem for the service providers
to solve, since there exist certain negative factors in the radiation environment contributing to
the limit in capacity
