LillyBelle aide les opérateurs à mesurer et améliorer la performance et la qualité de service sur les réseaux ayant déployé la LTE-A.
4G Americas announced that LTE A has been commercially deployed on 100 networks worldwide in 49 countries.
The first LTE-Advanced networks were deployed in South Korea in June 2013 and utilized Carrier Aggregation which has become the most popular technology feature of LTE-Advanced.
By December 2014, the number of LTE-Advanced networks had increased to 33 commercial networks worldwide, all of which had utilized Carrier Aggregation.
Carrier Aggregation allows operators the ability to utilize disparate spectrum bands to create larger spectrum swaths to increase efficiencies and download speeds.
« We expect almost all operators to deploy LTE-Advanced which has a vigorous roadmap of technological innovation, » commented Chris Pearson, President of 4G Americas. « LTE technology and its evolution will provide the mobile broadband foundation for future 5G technologies. »
LTE-Advanced will continue to evolve through LTE-Advanced Pro (3GPP Release 13 and beyond) even as 5G technologies are standardized in Release 14 and onward. It is expected that 5G technologies will interoperate with existing LTE-Advanced networks to provide subscribers with a seamless mobile broadband experience.
