3. The use of several antennas and Nultiple Input Multiple Output (MUMO) transmission echemes is found in 36PP rekase. 4. To reach even higher data spects, it is now possible to aggregate two adjacent UMTS carriers to get a total bandwidth of 10MH/Z this is referred to as. 5. What is the maximum unlink data rate achicied by an HSUPA (High-Spood Uplink Packet Access) enabled 3G network? 6. If a handover has to be performed to a cell which is connected to a sesond BSC. the current BSC is not able to control the handover iself as no direct signaling connection exists between the BSCs of a network. Which handower seenario is deseribed in this: context? 7. In case of 5MH. channel bandwidth, 300 subcarriers are used. For a perifct ille condition 64QAM can be used. That means each symbol is now allowed ao carry 6 bits. the total bits carried by 300 subcarriers for the duration of a symbol is 8. If I symbol is equivalent 71.4 microseconds for LTE. What is the dath rate? [NOTE: Take information from Q8] 9. For 10MHz what will be the maximum dats rate in downlink [NOTE: Take information from Q8] 10. The UMTS air interface uses a constant chip rate of 11. What is the name of the base transeeiver station in 26 system equivalent in a 4G LTE system? 12. What does WIMAX stands for? 13. In WCDMA, users are no longer separated from each other by timeshts and frequencies but are assigned a unique 14. Which organiration is responsible for developing LTE standards? 15. What type of handover is supported by LTE? 16. is a fadio communication system where componerts that have been. traditionally implemented in hardware are instead inplemented by means of sottware on a personal computer or embedded system?
