Question: What is the primary reason for verifying that a User Equipment (UE) occupied channel bandwidth is less than 5 MHz in a 3GPP-specified FDD system with a chip rate of 3.84 Mcps?
Option 1: To ensure efficient use of UE battery power
Option 2: To enhance the overall network's data transmission capacity
Option 3: To minimize excess interference to adjacent channels or other wireless systems
Option 4: To guarantee Quality of Service (QoS) for real-time communication services
Explanation: Verifying that a UE's occupied channel bandwidth is within specified limits is crucial to prevent excess interference. When a UE transmits at a bandwidth exceeding the standard, it can encroach on neighboring channels or even affect other wireless systems operating in proximity, leading to degraded performance across the network.
