4G LTE-A in U Band (Unlicensed Band)
应用文章
Why is 4G LTE-A expanding to the unlicensed band?
On the path to 5G, the current standard, 4G LTE-A continues to rapidly evolve, providing even faster data rates and supporting more mobile devices. With very little spectrum available in the licensed band, network operators are working on ways to support growing demand for voice and data connectivity. Possible collaboration with wireless technologies such as WLAN, and expansion of the 3GPP network’s spectrum domain to the unlicensed band are two approaches which have been topics of discussion within the 3GPP standardization body. This application note will cover LTE unlicensed band features that have been defined by the 3GPP along with major use cases and practical examples to help you address test challenges. Smart phones and access to higher data rates have changed the way we communicate. Because devices need to be constantly connected while sharing data with the Internet, network operators are challenged to find new ways to improve throughput and make their networks more cost efficient.
