When planning RF what do you choose: microwave transmission capacity or throughput KPIs?
KPIs for Throughput / Performance
68
Special Events increase capacity by
Disabling Carrier Aggregation. [575 587] CA enabled = 106 connections CA disabled = 320 connections PUCCH is limited by CA reporting Harq Ack and CSI for each carrier. More connections but less throughput.
