LTE Carrier Aggregation Deployment – From Standardization to Deployment
Telecommunications technology development need innovation generation. Often development relates improvements for data transmission rate and latency improvements on radio interface. When building new telecommunications standards where network and mobile station can communicate together irrespective of manufacturer, there is need for standardization where various technical features construct standard specifications. There is investigated whether LTE Carrier Aggregation commercial deployment intentions have happened in early phase after standard specifications for equipment implementation have been ready. The results show that LTE Carrier Aggregation has adopted to commercial usage immediately after standard specifications have been ready for implementation. LTE Carrier Aggregation is also basis for development path towards 5G technology.
Purpose: The objective of this research was to investigate LTE Carrier Aggregation commercial deployment and how soon it happened after standardization finalization. Because LTE Carrier Aggregation feature was expected to be important feature there is good reason to expect its deployment for real commercial markets.
Design/Methodology/Approach: Used methodology was to gather network operators' and equipment manufacturers' intentions for LTE Carrier Aggregation commercial deployment purposes during and after standardization finalization. Information found from public sources where commercial deployment intentions launched by companies.
Findings: The research showed that after and already before standardization finalized there were immediate intentions for LTE Carrier Aggregation deployment. Commercial trials appeared within one year and real commercial deployments appeared within two years from standardization finalization. That means soon deployments in commercial markets when considering deployment in licensed band.
Research, Practical & Social implications: For future works there could be study why not LTE Carrier Aggregation solutions in unlicensed band was not successful and whether there be will changes when going to 5G standard deployment.
Originality/Value: This article is an academic contribution for innovation feature commercial deployment in telecommunications industry and investigation whether LTE Carrier Aggregation feature deployment happened as soon as expected.
Key Words: LTE Carrier Aggregation, Standardization, Deployment, 5G technology.
