Heterogeneous networks

    Ericsson’s heterogeneous network solutions will address capacity and coverage demands in the most challenging areas. In city centers, transport hubs and business parks these network solutions will provide subscribers with a truly mobile lifestyle.

    Efficient use of spectrum

    Ericsson will meet this challenge with a heterogeneous network solution building on a strong interaction between every element in RAN and backhaul, thus providing both performance and cost efficiency. The key is to use available spectrum in the most efficient way.

    Ericsson advocates a three step approach where the combination and timing must be determined for each operator:

    Improve

    ImproveImprove the existing macro layer using our line up of new digital units, radio units and antenna configurations in existing sites. This is an attractive way to increase coverage, capacity and data rates as it doesn't require new sites.

    Densify

    DensifyDensify the macro layer by adding more small, lightweight macro cells that installs on walls or poles. This keeps the total number of sites relatively low resulting in low total cost of ownership.

    Add small cells

    Add small cells in additional layers as a complement to the macro layer. The small cells may be based on 3GPP standard (micro cells, pico cells or low-power remote radio units, RRU’s) and Wi-Fi. The performance will depend on how strongly the small cells can be integrated with the macro network.

    Mobile backhaul for heterogeneous networks

    To support a good end user experience, the backhaul needs to be planned and deployed according to the requirements of the mobile services it is intended to carry. Ericsson’s Mobile Backhaul supports this by providing cost efficient backhaul modernization and capacity upgrades when enhancing the macro layer. To densify the macro layer, scalable optical and microwave nodes are needed. To add small cells, compact all outdoor microwave solutions are the fastest and most cost efficient way to provide backhaul. Existing fiber and copper infrastructure can and will be re-used.

    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 on smartphones, tablets and other connected devices are driving figures for data traffic sky high. Heterogeneous networks efforts to improve and densify existing mobile broadband infrastructure together with added small cells are important when meeting ever-increasing user expectations.
