The main reason for me to buy the combination with landline handset, for me was the possibility of maximum radiation reduction. By landline I have the opportunity for longer conversations to call free of radiation, because the Sendesingal the base station will be shut down. But without renouncing the comforts also be able to telephone in the apartment mobile, through the additional Mobiltteil in short conversations or when it just once necessary. For 180.- Euro together though not chicken, but it is also not every year buys a new phone. Incidentally, I myself have measured that the transmission signal is down to almost zero after an initial peak (the fixed line network).
