Speed, capacity and demand define the mobile experience. Streaming video, games, applications and other data-intensive processes all drive mobile network operators to offer higher-bandwidth services to acquire and retain customers.

The challenge is to achieve these goals with spectrum that is fragmented across multiple bands and between regions.

Carrier aggregation (CA) is the answer.

CA enhances network performance and ensures a high-quality user experience by enabling operators to provide higher uplink and downlink data rates using their existing spectrum.

Accelerated Global Deployment of Carrier Aggregation

Operators use carrier aggregation as a differentiator to improve mobile performance. The ability to uplink or downlink data-intensive applications – from mapping, streaming video to cloud computing – with CA provides a major advance in network performance.

CA combines multiple LTE carrier signals to increase data rates and improve network performance. Currently, two-carrier aggregation is widely available throughout the globe. Traditional two- and three-CA configurations use the Frequency-Division Duplex (FDD) LTE bands. However, combining frequencies – Time-Division Duplex (TDD) / FDD CA – is becoming more widely available.

Initial LTE CA deployments aggregated only two Component Carriers (CCs) for a maximum data rate of 300 Mbps, but more CCs are being added each year. Faster speeds require more advanced modems in mobile devices; LTE Category 4 modems are required for 150 Mbps, Category 6 for 300 Mbps, and Category 9 for 450 Mbps. Category 9 will bring 450 Mbps with 60MHz during 2015, with expected rates of 1Gbps in the future.

Bottom line, CA provides significant benefits for mobile users and operators.

CA can also present challenges such as increased mobile power consumption; interference; and system noise. Addressing these challenges requires high-performance RF front-end designs and technologies. Qorvo is at the forefront, offering products with high linearity, low insertion loss, and the performance needed for CA – maximizing mobile battery life, mitigating signal interference and optimizing network coverage.
