The frequency reuse properties of LTE allow the addition of micro cells to provide sufficient capacity to support growing traffic levels. This solution, called HetNet, proposes adding anywhere from 10 to 100 small cells within each macro cell to support anticipated 10 to 100 times data traffic growth over the next few years, assuming capacity scales linearly and interference is managed effectively.
One of the challenges in deploying small cells is providing an appropriate backhaul mechanism. Since fiber is not always readily available, alternate means such as DSL, cable modems, and Line of Sight (LOS) and Non-Line of Sight (NLOS) microwave and millimeter wave radios are required. Due to the growing number of sites and the diversity of backhaul mechanisms needing to be managed, the deployment and provisioning of backhaul links is a significant contributor to operational expenses.
The Juniper Networks mobile backhaul solution addresses these operational aspects throughout the lifecycle of HetNet deployment. ACX Series Universal Access Routers acting as small-cell and macro-cell routers support zero-touch provisioning (ZTP) to minimize installation and deployment costs, while Junos Space Service Activation Director automates backhaul services provisioning, activation and maintenance to simplify typically labor-intensive processes.
Junos Space Service Now and Junos Space Insight provide remote, automated troubleshooting, reducing network downtime by delivering rapid, proactive bug notifications specific to network configuration. The result: a 40% increase in Day 1 issue resolution, further reducing total cost of ownership.
