This 4G Americas white paper explains the evolution of 3GPP technologies and the ITU roadmap that leads to IMT-Advanced and beyond.

LTE is the common global 4G standard for paired (FDD) and unpaired (TDD) licensed spectrum. We can now extend the benefits of LTE Advanced also to unlicensed spectrum, the shared resource used by multiple technologies such as Wi-Fi. This is an ideal solution for mobile operators to augment mobile broadband and help to meet the 1000x challenge.

Frank Rayal, Telesystem Innovations - The design of the LTE physical layer (PHY) is heavily influenced by requirements for high peak transmission rate (100 Mbps DL/50 Mbps UL), spectral efficiency,

This Qualcomm paper explores the revenue opportunities and cost benefits MNOs can realize through the implementation of LTE Broadcast, a mobile broadcast solution that complements LTE networks.

The high computation demands of next-generation cellular and broadcast wireless require both higher efficiency and greater flexibility in baseband processing.

This article from Freescale provides an excellent introduction to the LTE physical layer. The topics included are:

- LTE basic concepts
- Introduction to OFDM
