Urban Densification

Mobile data traffic volumes have been growing exponentially, almost doubling from one year to the next. With the introduction of Internet of Things (IoT), smart cities and connected infrastructures with 5G, the demand for capacity will continue to grow.

To cope with this demand, mobile operators need to find ways to utilize the available radio spectrum resources in the most efficient way. There are four ways to increase capacity:

• Utilizing new technology with more efficient modulation and coding schemes like 5G
• Buying more spectrum
• Using spectrum more efficiently (See RAN Virtualization)
• Densifying the network

Urban areas and large venues with high concentration of mobile users often need network densification to increase the amount of capacity per square meter. This is usually accomplished by adding more cell sites to cope with the corresponding increase in traffic. However, in many premium real-estate areas, space is limited.

Dali Wireless Urban Densification Solution:

Dali Wireless urban densification solution can deliver precision coverage and capacity with low power remote radio units to multiple cell sites to densify congested networks. To minimize interference between various cells, one cell is created through software configurable simulcasting.

In addition, with Dali’s patented digital signal processing, multiple operators signal can be digitally processed and combined ensuring no degradation of signal. It also eliminates the additional passive inline amplifiers, splitters and combiners traditionally found with Distributed Antenna System (DAS) deployments. Beyond savings on equipment costs, owners and operators realize real-estate and ongoing operating cost savings.

The digital signal processing also enables centralized base station resources. This means multiple mobile operators’ base station resources can be centralized in a local fiber center or data center and delivered to high capacity areas over long distances.

With the exponential growth of mobile data traffic, and the coming of age of 5G, capacity demand will further increase. With Dali network densification solution, mobile operators or even sectors can be added incrementally to the common distribution network with no loss of signal quality and with no changes to the existing distribution network. With Dali’s software configurable simulcasting, cell sizes can dynamically shrink to accommodate the increase in mobile traffic. This enables mobile operators to easily scale.

With this next generation solution, mobile operators can effectively handle the capacity crunch and utilize the precious spectrum resources in the most efficient way.
