Small Cells are a Big Deal: Small cells, or more specifically, low power base stations, have been part of mobile operator non-residential 3G rollouts for at least 5 years.? They are not a big deal to date, with most small cells silently deployed in-building for 3G coverage, totaling less than 250,000 cumulative to date.? The big fuss is about the slowly beginning rollout of outdoor picocells for capacity for 3G and later LTE.? Outdoor small cells will principally be deployed on lightpoles, traffic lights, and the sides of buildings in urban cores, and their operation will be coordinated with the nearby macrocells, putting prime stress on capacity, latency, and timing/synch for backhaul.? Another wrinkle: many outdoor deployments will include carrier WiFi, which brings both simplification and complexities to the network design and operation.? Operators will use Ethernet copper and fiber where available, but will predominantly use microwave, millimeter wave, and NLOS microwave for the immediate small cell backhaul link.? Clock timing/synch must be supplied to the small cells and IEEE 1588v2 is the preferred technology.? North America has strikingly different macrocell backhaul trends versus the rest of the world, but small cell backhaul will face the same issues across the globe.? The speaker and Infonetics team have conducted research for the past 2 years with mobile operators around the world, and will present their preferred architectures, backhaul technologies, design assumptions, vendors, and the daunting barriers.? Outdoor small cell deployments are not going to be easy or quick, but they will be a big deal in the long run.
Small Cells and the Critical Role of Microwave: Backhaul has become one of the most critical aspects of mobile networks.? This is especially true in the implementation of LTE networks.? The first part of this talk will focus on the experiences of building LTE backhaul solutions.? The current backhaul solutions used for Macro Cells will clearly have to be different for Small Cells and the second part of the talk will address the challenges and the potential solutions.? Finally, the future of Microwave Networking will be addressed and how the demands of the network evolution will influence innovation and what techniques and technologies will emerge to address the challenges.
