Recent Whitepapers

  • Delivering Voice Using HSPA

    This 4G Americas white paper describes the technological features that are being developed for Voice over HSPA (VoHSPA) and recent simulations that substantiate the anticipated benefits of VoHSPA.

  • The Move to Small-Cell Architectures

    The expansion and evolution of cellular networks over the past decades has been astounding. Networks initially designed for voice traffic have grown to accommodate increasingly high data-traffic loads. This growth has long relied on a network of macro cells to provide a good balance of wireless coverage and
    capacity.

  • Meeting mobile broadband expectations with maximum efficiency

    As the Networked Society takes shape, providing the right user experience is a top priority for operators. Bandwidth-hungry applications common on smartphones, tablets and other connected devices are driving figures for data traffic sky high.

  • It all comes back to backhaul

    Ericsson - Backhaul plays a critical role in mobile broadband, and is rising in importance on account of the introduction of heterogeneous networks, known as hetnets.

    Deploying vast numbers of small cells to complement improved and densified macrocell layers will require a range of highly scalable, flexible mobile backhaul solutions that support superior user experience.

  • Voice and video calling over LTE

    Ericsson - The GSMA IR.92 voice-over-LTE and GSMA IR.94 IMS conversational video specifications are the preferred industry choices for mass-market voice and video calling services over LTE, satisfying user expectations and providing the most advantageous solutions for operators.

  • 3GPP Release 10 and Beyond - HSPA+, SAE/LTE and LTE-Advanced - Update

    This 4G Americas document is an updated version of the February 2011 white paper and includes a new Appendix A: Detailed Member Progress and Plans on Release 99 through Release 10 and updated deployment and subscriber information.
