The adjacent channel interference in downlink may cause dead zones around interfering base stations. In this section we evaluate the sizes of these dead zones as a function of the coverage of the own signal. The coverage is defined as the received pilot power level. The results show that the dead zones can occur only if the following conditions take place at the same time: own network coverage is weak, the mobile is located close to the interfering base station that is operating on the adjacent frequency with maximum power, and UE performance is just meeting 3GPP selectivity requirements.

In this case it is equal to the pilot power level since the maximum transmission power for voice is assumed (C11) to be equal to the pilot power of 33 dBm.
