Question: What is the primary purpose of applying additional spurious emissions requirements to an E-UTRA Base Station (BS)?
Option 1: To enhance the overall transmission power of the E-UTRA BS within its designated operating band.
Option 2: For the protection of systems operating in frequency ranges other than the E-UTRA BS downlink operating band, potentially including GSM, CDMA, UTRA, and NR.
Option 3: To ensure seamless handover between E-UTRA and non-E-UTRA networks within the same geographical area.
Option 4: Exclusively to safeguard User Equipment (UE) from interference caused by E-UTRA BS emissions.
Explanation: The main objective of these requirements is protecting systems that operate on different frequency ranges than the E-UTRA BS downlink band, preventing interference and ensuring coexistence with other wireless systems in the same or overlapping geographical areas.
