LTE-Advanced is the version of LTE (Long Term Evolution) that addresses International Mobile Telecommunications-Advanced (IMT-Advanced) requirements. In a nutshell, LTE-Advanced is a further evolution of LTE, which provides faster speed and higher capacity.
What is LTE-Advanced?
LTE-Advanced mainly offers increased peak data rate, higher spectral efficiency, increased number of simultaneously active subscribers, and improved performance at cell edges. LTE-Advanced is also both backwards- and forwards-compatible with LTE. LTE-Advanced leverages the following technologies: Carrier Aggregation (CA), enhanced use of multi-antenna techniques and support for Relay Nodes (RN).
In comparison, LTE-Advanced offers data download speeds up to 1 Gbps (30 bits per Hz) and 500 Mbps uploads (16 bits per Hz) while LTE only provides maximum download speeds up to 300 Mbps (15 bits per Hz) and 75 Mbps uploads (3.75 bits per Hz). Eventually, it is highly likely that operators will upgrade their LTE networks to LTE-Advanced to obtain more spectral efficiency and capabilities. In short, LTE-Advanced will deliver a better user experience with faster speed and more reliable connection.
In late June, QUALCOMM, Inc. (NASDAQ:QCOM) delivered the world’s first LTE-Advanced smartphone, the Samsung Galaxy S4 LTE-A, powered by the QUALCOMM, Inc. (NASDAQ:QCOM) Snapdragon 800 processor. Samsung will launch the new Galaxy S4 LTE-A on all operators’ LTE networks in Korea, available to customers in Korea this summer. Galaxy S4 LTE-A will be the first smartphone utilizing LTE carrier aggregation for data rates up to 150 Mbps, offering 2x of what current LTE speeds offer.
LTE carrier aggregation is a significantly new technology, allowing for simultaneous download on two or more LTE radio channels. Snapdragon 800 processors are designed to support LTE carrier aggregation without sacrificing battery life while enabling operators to boost both peak and average data rates. QUALCOMM, Inc. (NASDAQ:QCOM), as a leader in LTE-Advanced, believes that LTE-Advanced is not only about adding small cells, instead, it’s about realizing full benefit of heterogeneous network (HetNet), referring to the use of multiple types of access nodes in a wireless network. QUALCOMM, Inc. (NASDAQ:QCOM) is a main contributor to key LTE-Advanced features and will continue to push forward the development of LTE-Advanced technology.
As for the carrier, SK Telecom Co., Ltd. (ADR) (NYSE:SKM) also announced the launch of the world’s first publicly available LTE-A network with the world’s first LTE-A compatible phone, Samsung Galaxy S4 LTE-A. SK Telecom Co., Ltd. (ADR) (NYSE:SKM) has successfully developed and applied the most-advanced mobile network technologies, including Carrier Aggregation, to commercialize LTE-A.
