Why is synchronized operation used in LTE TDD base stations?
to allow downlink MIMO to be used
to allow handovers to LTE FDD carriers
to achieve good RACH timing accuracy
to reduce interference between uplink and downlink
What are two benefits of massive MIMO? (Choose two.)
It serves many users in the same time and frequency with a single element antenna.
It increases SINR by focusing a signal toward an individual user.
It serves many spatially separated users in the same time and frequency.
It increases throughput by allowing access to larger spectrum slices.
What are two benefits provided by the introduction of GPRS/EGPRS Downlink Power Control in a GSM network? (Choose two.)
reduced power consumption in RBS
reduced downlink Interference levels In the system
reduced uplink interference levels in the system
increased PS accessibility
