IWPC Heterogenous Networks Workshop

NEW – International Wireless Industry Consortium
Interactive Technical Workshop

Workshop Background: Introduction: Data usage on the mobile operator's network is growing exponentially, creating significant strain on the user experience such as blocked calls, unsent messages and slow WEB access. As the industry look towards LTE & WiMAX networks, the operators are looking for ways to meet the capacity demands in a most cost effective manner while managing interference across potentially three networks. How can the supply chain help the operators with this major challenge? Definitions: Heterogeneous Network - A tiered network deployment that supports macros, picos, femtos, relays, DAS and WiFi in the same spectrum. Macro - conventional base stations that use dedicated backhaul and open to public access. Typical transmit power ~43 dBm; antenna gain ~12-15 dBi. Pico - low power base stations that use dedicated backhaul connections and open to public access. Typical transmit power range from ~ 23 dBm-30 dBm, 0-5 dBi antenna gain. Femto - consumer-deployable base stations that utilize consumer’s broadband connection as backhaul; femto base stations may have restricted association. Typical transmit power < 23dBm. Relays - base stations using the same spectrum as backhaul and access. Similar power as Pico’s. Source of Definitions: Heterogeneous Networks – A new paradigm for increasing cellular capacity Avneesh Agrawal, Qualcomm - http://netseminar.stanford.edu/seminars/01_29_09.pdf (slide 5) Small Cells - micro, pico, relay, consumer femto, enterprise femto, and WiFi. DAS - Distributed Antenna Systems SON - Self-Optimization Networks CoMP - Coordinated Multipoint a.k.a power combining G's - referring to the 2G, 3G, LTE & WiMAX Networks
Workshop Goals: The Goals of this workshop are to have a clearer understanding of: Market and technology clarity for each layer of the Heterogeneous Networks Market and technology clarity for backhaul requirements for each layer of Heterogeneous Networks Interference management between layers of the Heterogeneous Network Load balancing requirements between layers of the Heterogeneous Network The impact of the Het Net on future portable devices. To accomplish these goals, we will bring together senior leaders from THE ENTIRE SUPPLY CHAIN to facilitate and stimulate breakthrough thinking on these emerging technologies, in a highly interactive workshop format.

10:20 AM	Mobile Wireless Operator Requirements Operator's Use Cases What are the operator’s use cases and priorities for deploying macro, micro, pico, relay, enterprise femto, consumer femto, DAS and WiFi? Density Capacity Forecasts are showing that the macro networks may not be able to handle the capacity, even with LTE, in a few years. How will the recent push for more spectrum-- and an apparent willingness by the Spectrum Regulators to entertain the idea-- affect the timeline for Het-Nets? Coverage Speed Post LTE, spectral efficiency improvements will be mild. Is improved end-user signal quality driving this concept? Costs Will Het-Nets increase operator costs, or shift them to end-users (e.g., femto-cells)? Will there be a potential paradigm shift in the U.S. towards shared network infrastructure, to prevent the potential for pico cell farms? Managing user applications for lowest costs How can WiFi offload capacity of mobile network? Site Planning How can Het-Net help optimize future CapEx/OpEx for the operator? How will a Het-Net be designed across legacy 2G, 3G and LTE & WiMAX networks? What are decision criteria for choosing which cell type for which "G" network? What is the design impact of dense urban vs. urban vs. suburban vs. rural? What are the design considerations for various network cell types for various capacity requirements? cell splitting vs. coverage? What are the selection criteria for deploying macro, micro, pico, relay, enterprise femto, consumer femto, DAS and WiFi considering the following variables? Available sectors Transmit Power/Range Costs Performance (Spectral Efficiency or Capacity) Latency Backhaul Supported simultaneous bands What is the role of the femto in the Het-Net architecture? How can operators manage the high volume deployment of small cells for: Ease of Installation? Coverage? Capacity? Radio Access Issues* What are the Het-Net design considerations for: Cell splitting Interference - Outdoor networks and indoor networks Expected Inband interference scenarios Range extension Load balancing (capacity) For various "G's" What is the impact of towers >200 feet (boomer sites) on neighboring small cell deployment? What are best practices for handover management for MIMO channel conditions in a heterogeneous network? What are the Het-Net RF tradeoffs between coverage and capacity for deploying macro, micro, pico, relay, enterprise femto, consumer femto, DAS and WiFi? Transport (Backhaul) How will backhaul be handled for small cells, when 4G solution is an issue today for macro networks? How will quality of service be maintained? How will relays be positioned among the other cell types as a Backhaul alternative to fiber and/or wireless? In what circumstances will operators use spectrum for backhaul with relays? Given the complex topology of all of these various cell types, what will a future Het-Net backhaul network look like? Will each network cell type have a backhaul link to the central office? Will each network cell type be linked to each other in a "mesh" then aggregated back to the central office? Something else? How effective is using consumer broadband (DSL, cable modems, etc.) in small cell deployments? OR - will the bandwidth requirements of the various cell types exceed these consumer broadband options? Network Management How will operators manage multi-tiered cell types (the Het-Net) across multiple "G" networks? How can network management be made simpler? How does the operator plan to manage multiple vendors in SON environment? Will the success and evolution of SON ultimately determine how effective Het-Nets can be? What breakthroughs in network management be needed for Het-Nets? How can the number of system management parameters be reduced? How can overall complexity can be reduced?
