What are carrier aggregation technology and higher-order modulation technology?
Carrier Aggregation (CA) is a key component of 4G evolution technology (LTE-A), also known as 4G+. By using carrier aggregation technology, both uplink and downlink speeds can be significantly improved. For example, dual-carrier FDD can achieve a downlink peak rate of up to 300 Mbps and an uplink peak rate of up to 50 Mbps, which is twice as fast as 4G. This technology effectively meets the spectrum compatibility requirements of LTE and LTE-Advanced systems, accelerates the standardization process, and maximizes the use of existing LTE devices and spectrum resources. In simple terms, it combines multiple carriers of the 4G network, similar to upgrading from a single-lane road to a multi-lane road, thereby greatly increasing traffic capacity (speed). The obvious benefits include a significant increase in transmission speed, reduced latency, improved network quality, enhanced throughput, and more balanced network load, especially noticeable under heavy load conditions. Implementing this technology requires both hardware and system support. CAT6 uses dual-carrier aggregation, while CAT9 uses triple-carrier aggregation.
Higher-order modulation technology effectively increases data bandwidth and enhances the unit capacity for data transmission, similar to having larger vehicle capacity on the road.
