55. Functional description
The TPA extends cellular coverage in such indoor environments that can't be
economically and easily reached by radio mobile network signals.
RF signals going through walls, metallic structures and any other obstacle inside
buildings are attenuated up to 1000 times (30 dB), thus creating problems for the
users of mobile phones.
TPA together with TFA solves this problem by providing a suitable amplification,
which compensates the fading effect due to various artificial obstacles placed
between mobile phones and Radio mobile Network.
The TPA can be high-gain directional or low-gain semi-directional, see product
family datasheet for detailed radiation patterns
The appliance to the following instructions grants the best functioning, the
maximum safety and the lowest inference with other electrical devices.
Any misuse and any violation of the device compromise its functioning and exclude
any warranty.
