Hot off the press! New book on LTE small cells and unlicensed band utilization
Everybody likes a success story - and LTE technology has turned out to be a great success given its remarkable performance and global economies of scale. Data traffic carried by the LTE networks has increased rapidly as customers increasingly discover value in the mobile broadband connectivity. And along with higher network loading and the more demanding services like Voice over LTE (VoLTE) and video streaming comes the need for more advanced network optimization solutions and deployment of small cells. Likewise, unlicensed frequencies provide access to more spectrum and higher data rates. LTE-Advanced can utilize unlicensed spectrum through a number of techniques.
- Licensed Assisted Access (LAA) also known as LTE-Unlicensed (LTE-U), which is an aggregation of licensed and unlicensed bands LTE. Nokia is already testing the LAA solution with customers.
- LTE - Wi-Fi aggregation (LWA), which combines licensed band LTE and unlicensed Wi-Fi.
- MulteFire, which is a standalone LTE solution in unlicensed bands.
But I don’t want to give away the entire story here. These solutions are illustrated in the figure below.
And the small cell topics are addressed in our new book: “LTE Small Cell Optimization: 3GPP Evolution to Release 13” authored by technology experts from Nokia, T-Mobile (USA) and Videotron (Canada). The book describes R&D and standardization activities on LTE small cells and network optimization, focusing on 3GPP evolution to Release 13 - also known as LTE-Advanced Pro. Among the topics covered include LTE small cells from specification to products and field results, the latest 3GPP evolution to Release 13, and LTE optimization and field studies.
If you don’t have time to read the whole book, Nokia will publish a white paper about unlicensed bands in the near future - watch this space
